Thorstenson gave a presentation on Drive
Selection for Rolling Mills, in the Long
Product Projects Session at the
annual Iron & Steel Technology
Conference and Exposition (AISTech).
The conference was held in Pittsburgh,
PA, USA this year from May 3-6 with an abundant turnout of
over 6000 attendees.
The Russula paper concentrated on the selection of low
voltage, less than 1000 V, variable speed motor drives for
long product rolling mill applications. Among the selected
principles discussed were:
• Long product rolling process
• Drive selection criteria
• AC vs. DC drives
• Braking
• Rectifier section types
• Common DC Bus AC drives
• Maintenance considerations
• Installation considerations
• Rebuilds vs. buying new
´DC and AC drive technology are at an interesting cross-
roads with implications in rolling mill technology of great
importance. With properly selected drive systems, product
dimensional control is very precise.´ stated Eric Thorstenson.
The presentation was received well and started a lively dis-
cussion.

MAINTENANCE TIPS
All modern variable speed AC motor drives consist of threemain sections:
1. Mains frequency AC to DC section called a rectifier
(or active front end)
2. Capacitor energy storage/filter section
3. DC to variable frequency AC section called an inverter.
Aluminum electrolytic type
capacitors are used for the
energy storage / filter sec-
tion. Aluminum electrolytic
capacitors are constructed
from two conducting alumi-
num foils, one of which is
coated with an insulating
oxide layer, and a paper
spacer soaked in an elec-
trolyte fluid. This combi-
nation of aluminum foils
and paper is rolled up and
contained in sealed aluminum cans. Typically about the size
of a soda can each.
Older AC drives using GTO switching devices required very
large capacitor banks which were typically mounted in a
distinct section. Modern IBGT based drives require less
capacitance, and generally include the capacitors in the
individual inverter section(s).
These type of capacitors have an inherit storage problem.
The oxide insulating layer will tend to deteriorate in the
absence of a sufficient rejuvenating voltage, and eventually
the capacitor will lose its ability to withstand voltage, if
voltage is not applied.
Individual capacitors, as well as those in inverter modules or
even complete drives purchased as spares are subject to this
deterioration. For this reason Russula recommends rotating
these spare components, from spares storage to a working
drive once per year. Failure to perform this preventative
maintenance may result in shortened life or even immediate
failure of the spares when put into service.
As an alternative to rotating the spares, capacitors in storage
for over a year can often be "reformed" by connecting them
to a voltage source through a resistor and allowing the
resulting current to slowly restore the oxide layer. The drive
module manufacturers, such as ABB or Siemens, publish
“reform” procedures which involve an external power
supply which gradually steps up the voltage over a few days’
time. For spares without voltage for over two years, this
external method of reform is recommended.
The annual rotating procedure is simpler, and provides the
added benefit of practice in replacing the components.

In the celebration of ILAFA in Buenos Aires, Argentina last
October, it brought Russula to reflect upon an important
milestone in 2007; the Acindar SBQ project followed by the
subsequent opening of a Russula technical office in San
Nicolás, Argentina.
In 2007, Russula supplied the complete water treatment plant
and electrical equipment and installation for Acindar´s
(ArcelorMittal) new 500 kt/y combination bar and wire rod
mill, located in Villa Constitución, Argentina.
The new high-efficiency mill is designed to roll special bar
quality (SBQ) products for high-end industrial applications,
including the automobile industry. Products range in size
from 5.0 to 88.9mm round bars, as well as squares,
hexagonal, flats and rebar.

Rolling Mill Plant Data
A Compact Water Treatment Plant
The new water treatment plant, supplied on a turnkey basis,
features Russula´s unique technology combination of twin
decanting basins, mechanical ring filters and modular
cooling towers. This was the first water treatment plant of its
kind, implemented in Argentina and designed specifically
for steel production. Due to the Acindar site limitations for
the water treatment installation, Russula designed a very
compact water treatment plant occupying a total area of
3550m2.
The water treatment plant is rated for 3,000m3/h and pro-
vides the mill with clean cooled process water. The sludge
from the decanting basins passes through a thickener tank
before being formed into bricks by a press pack filter. An oil
skimmer removes any oil and grease. The ring filters are
self-cleaning.
Russula was responsible for the complete mechanical and
electrical supply and provided detailed civil designs for the
installation, including the embedded rebar and conduits.
Russula also provided extensive installation advisement;
commissioning and training.

Acindar Maintains 118m/s with Russula Rolling Mill Automation
Russula supplied the complete rolling mill automation, all
the electrical and control equipment, and level 2, AC and DC
drives and an IBA data acquisition system. The combination
mill features controlled temperature rolling, which permits
Acindar to produce thermo-mechanically rolled rod and bar
product. Acindar´s production speed reached 118m/s, well
above the Morgan guarantee of 110m/s due in part to the
consistent and reliable automation system provided by
Russula. The project scope consisted of consulting,
engineering, installation, and start-up and training.
In order to have a successful start-up and reach 118m/s
rolling speeds with excellent product quality, there were
three principal challenges that Russula had to overcome,
states José Luís Casanova, the Russula Project Manager.
To begin with the system integration was complex, the
mechanical supplier Morgan supplied a different electrical
system, which must be integrated with Acindar´s existing
plant management systems and the new control system for
the Greenfield SBQ mill.
¨Russula tackled this problem by first doing a study of all the
different existing solutions available on the market. Then we
evaluated and selected the best solution based on our
know-how from implementing similar projects.¨ says José
Luís Casanova
Second a challenge to all project managers is to complete the
project deadlines; in the case of Acindar the delivery time
spanned approximately 1.5 years. This project was executed
on time and managed well according to Casanova. Russula
follows a standard project management process for purchas-
ing, assembly, delivery, installation and start-up.
And lastly the most important project challenge was for the
SBQ mill to achieve optimum functionality at 110m/s.
¨During the performance test for the mill, we were able to
sustain a consistent production rate of 118m/s for many
hours, much higher than the rolling mill guarantee. On the
control side, this can be attributed to an optimized control
configuration and final drive adjustments.¨ affirms Casanova
Acindar and Russula have had a successful partnership
dating back to 1995, when Russula upgraded the control
system for their other two strand wire rod mill in Villa
Constitución. Since 2002, Russula has completed numerous
electrical projects for Acindar in San Nicolás and Navarro.
This Greenfield SBQ mill marks the 5th and largest project
for Russula with Acindar.

we were able to sustain a consistent

Introducing Russula´s Mathematical Model for Reheating Furnaces
By: José Luis Casanova, Project Manager
The complete set of Russula re-heating furnace control pro-grams result in effective furnacecontrol, improving heating effec-tiveness and heating gas con-sumptions. Short pay-back timesare obtained due to the effective-ness of furnace gas consumptionreduction; especially at installa-tions without any previously existing optimization control program.
Russula has developed and implemen-
ted a Mathematical Model for the
reheating furnace. This Mathematical
Model is currently in operation at two
furnaces after undergoing a testing and
validation process. Russula sponsored
a chair and jointly developed the
Mathematical Model with the Vigo
University Applied Research Depart-
ment (Universidade de Vigo).
The Mathematical Model complements
the existing Russula reheating control
modules including level one control for
combustion and logic; level two for
heating strategies and delay multipliers
and a pyrometer feedback module.
The Level one program is the basic
furnace control and includes two
functions; combustion control and
furnace logic. Combustion control is
responsible to control common regula-
tion functions such as combustion air
pressure control, furnace pressure
control, gas pressure control and
recuperator protection functions;
furnace zone temperature control func-
tions and cooling supervision functions
are also included at this program level.
Furnace logic is the program that
controls all charging, discharging,
hydraulics and walking beam
functions.
The Level two functions generate
automatic heating set-points based on
strategy tables and delay multiplier
tables. A material tracking program is
used at this control level (alternatively
upon customer request the tracking
program could be included as an option
for level one function). The tracking
program keeps track of all the material
(billets, blooms and slabs) inside the
furnace; it detects where different
quality material is located, and decides,
which heating strategy should be
applied to a particular furnace control
zone. This decision is based on
material data information received
from the operator or plant management
software. Information regarding which
strategy should be applied, and data
regarding material speed inside the
furnace are used to automatically
generate set-points for zone tempera-
ture control automatic operation.
Furnace stops are controlled by delay
multiplier tables, which generate the
appropriate lower setpoints in the case
a furnace stop is twice the average time
between two furnace discharges.
The Pyrometer feedback module
corrects automatic temperature set-
points for the heating and preheating
furnace zones. This correction is based
on pyrometer temperature feedback
from the material after leaving the fur-
nace, while it is rolling.
The reheating furnace Mathematical
Model is a program intended to detect
material temperature deviations inside
the furnace against an ideal curve that
could be supplied by furnace construc-
tor or optimized by a rolling company
based on their experience and know-
how. The Mathematical Model pro-
gram estimates material temperature
for each product inside the furnace
based on material speed inside the
furnace, burners’ power and furnace
temperatures. The estimated tempera-
tures obtained are compared against an
ideal curve and the deviation is used to
calculate a correction for the furnace
automatic temperature set-point gene-
ration system. The Main objective for
the Mathematical Model program is to
detect material heating deviations due
to a lack of cadence in material dis-
charging that cannot be corrected by
the delay multipliers control program
and could lead to a material over-
heating or under heating.
The Russula approach to develop the
reheating furnace Mathematical Model
begins with a static analysis on normal/
standard operating conditions. The sta-
tic analysis simulates the material
heating inside a furnace full of material
under fixed power and material speed
conditions.
In general, the material temperature
will be affected by initial conditions in
addition to heating conditions. Heating
conditions are determined by
convection heat exchange between the
material and the gases inside the
furnace and the heat exchange with
burner flames, furnace walls and other
pieces of material through radiation. In
the case of a walking hearth furnace,
conduction heating between the
furnace and the material pieces will
have influence, too. In general, heating
conditions will be affected by:
- product position inside furnace
- flame temperature
- gas temperature inside the furnace
- furnace wall temperatures
- material temperature
- temperatures of other material
pieces
The Static analysis is a mathematically
detailed simulation of furnace material
heating under standard and stable
heating conditions. All mentio-
ned heating conditions are
analysed to generate furnace
and material heating data.
Main output data from this
analysis are shown in these
three graphs:
- fume temperature graphs
- radiation temperature
- material piece temperature
(one graph per each piece)
Figure 1 “Fumes Temperature
Graph” shows the result of a
static analysis inside the fur-
nace with a fume temperature
representation. In the above
example one can see how the
higher temperature fumes are
generated by the heating cen-
tral burners. Also a fume flow
analysis inside the furnace was
conducted and shows how the
fumes flow from the burners to
the fume exit. As well, different
gas tempera-tures close to the
material pieces at the bottom
and upper sides are shown in
the graph. Please note that the
temperature is expressed in
Kelvin degrees.
Figure 2, “Radiation Tempera-
ture”, shows data related with
the burner’s temperature,
furnace wall temperatures and
material pieces temperatures.
Once again data values are in
Kevin degrees. Note that the
furnace wall temperatures can
also be observed on this graph.
Wall temperatures are the
detected value of furnace
thermocouples when properly
installed on the furnace roof or
walls. Furnace fume temperatures or
burner temperatures are higher than
the temperatures observed by furnace
thermocouples on the roof or walls, as
can be seen in analyzing figures 1 and 2
together.

TECHNOLOGY
The Figure 3, “Material Piece Tempera-
ture”, plots detailed data of one billet
temperature obtained from furnace sta-
tic analysis. The static analysis gives all
the data for each furnace billet;
analyzing each billet material tempera-
ture in the nucleus and outside the nu-
cleus, and the differences between
material corners and other points.
The static analysis is an intermediate
step to construct the Mathematical
Model; all obtained data must be
analyzed and checked to ensure that
critical information regarding the
furnace (geometrical data, burner
power, walls, materials, ect.) is correct.
Static data can be also being confirmed
with a material thermocouple test along
the furnace.
The thermocouple test is a data
recording operation where a data
acquisition system collects all furnace
parameters (temperatures, powers,
set-points, fume temperature) and the
data from several thermocouples
installed on a test piece that goes
through the furnace in a normal heating
process. Continuous furnace operation
is required to validate the data obtained
from this test in order to be able to
check the data with the static analysis
output data.
The static analysis is a complex
mathematical process that requires
hours of computer calculations.
Russula has developed a simple
modelling system based on the data
obtained from the static analysis to
furnace material temperature on-line
independent of furnace speed and other
heating parameters. This development
based on the modelling techniques is
the furnace Mathematical Model.
The furnace Mathematical Model pre-
dicts on-line, each minute, material
temperature for all material pieces
inside the furnace. This data is
compared with the ideal heating data
and used to correct the automatic
furnace set point generation program.
The most important factor for
validating a model is its repeatability,
the same answer against the same
heating conditions.
Once again, the thermocouple test is a
useful tool to check on-line material
heating prediction. Figure 4 “Thermo-
couple Test Complete” shows the
different values obtained during a real
test. Three thermocouples were
installed on a billet; thermocouples 1
and 3 located close to the billet ends
and thermocouple 2 installed in the
middle of the billet. Mathematical
Model predictions show the billet at
each position in the furnace.
The Mathematical Model program
must have a high repeatability; this
means that results obtained under
similar heating conditions must have
similar temperature values. It is
impossible to repeat the same heating
and material speed conditions from one
production day to the next on a real
installation, but under similar condi-
tions results obtained must be similar.

This is the repeatability concept for the
Mathematical Model program.
Billet temperature differences between
model estimation and thermocouple
test values could be adjusted by offset
adjustments, but it is absolutely
necessary to get similar results against
similar input conditions that lead to do
an accurate automatic set point
correction.
Figure 5 “Different Billet Comparative”
shows Mathematical Model data
obtained by two different billets at
different times under similar
production conditions. The same
production speed, same final heating
temperature target and same steel
degree are the conditions for this test.
Graph 5 “Different Billet Comparative”
shows estimated temperature differen-
ces under similar production condition
are lower than 10 ºC in various
positions inside the furnace.
The furnace Mathematical Model gives
a good estimation of material heating
inside the furnace and is used to adjust
heating requirements to optimize
furnace combustion. This adjustment
will finally result in improving of the
heating process and will result in a
positive economic impact by reducing
the gas consumption in the furnace,
reducing the cost per produced ton;
and result in an environmental impact
by reducing atmospheric emissions.
The complete set of Russula reheating
furnace control programs result in
effective furnace control, improving
heating effectiveness and heating gas
consumptions. Short pay-back times
are obtained due to the effectiveness of
furnace gas consumption reduction;
especially at those installations without
any previously existing optimization
control program.

Steel has been an interesting subject
for the last two decades and it con-
tinues to keep the adrenalin high till
date. Crude steel production in 2009
was 1227 Million Metric Tonnes. In
2010 production reached 1413 Million
Metric Tonnes. China steel leads in
terms of crude steel production and
the year on year growth is nearly the
same.
Steel industry reformsin 1991 and 1992 haveled to strong and sustainable growth in India’s steel industry
Since its independence, India has
experienced steady growth in the steel
industry, thanks in part to the
successive governments that have
supported the industry and pushed
for its robust development and private
investors who have taken advantage
of the opportunity to help build the
steel industry in India.
1991 A substantial number of
economic reforms were introduced by
the Indian government. These reforms
boosted the development process of a
number of industries, in particular the
steel industry in India, which has
subsequently developed quite rapidly.
The 1991 reforms allowed for no licen-
ses to be required for capacity creation,
except for some locations. Also, once
India’s steel industry was moved from
the listing of the industries that were
reserved exclusively for the public sec-
tor, huge foreign investments were
made in this industry.
1992 Yet another reform for India’s
steel industry came in 1992, when
every type of control over the pricing
and distribution system was removed
making the modern Indian Steel
Industry extremely efficient as well as
competitive. In addition to this a
number of other goverment measures
have also stimulated the growth of the
industry such as unrestricted external
trade, low import duties and an easy
tax structure.

Current Indian SteelSector Scenario
The Indian Steel Industry has been
moving from strength to strength and
according to the Annual Report 2009-10
by the Ministry of Steel, India has
emerged as the fifth largest producer of
steel in the world and is likely to
become the second largest producer of
crude steel by 2015-16.
With a strong demand from autos and
engineering services, the domestic steel
demand in India remains robust, as per
Moody's sectorial analysis on Asia's
steel sector. According to the analysis,
the outlook for the domestic operating
environment is positive, driven by
robust growth in infrastructure, autos
and construction and constrains on
additional supply by 2011.
Recently, Mr Virbhadra Singh, Minister
for Steel, said that India will become the
world's second-largest steel producer
by 2012, with a capacity of 124 million
tonnes (MT) as part of the push being
given to assist overall infrastructure
development.
Production
India's steel production during 2009-10
was 64.88 million tonne (MT), up 11 %
from a year ago, according to Mr A Sai
Pratap, Minister of State for Steel.
During the end of the second quarter in
September 2010, steel majors Tata Steel
and Steel Authority of India Ltd (SAIL)
reported a high growth in steel sales.
SAIL registered sales of 3.17 MT in the
period under review, while Tata Steel's
total sales for the quarter stood at 1.66
MT which is around 14 % higher than
the corresponding quarter last year.
Meanwhile, JSW Steel's production
during the quarter grew by 8 % to 3.14
MT on the back of a steady rise in
demand.
Consumption
The domestic steel consumption grew
by 9.8 % to 29.82 MT during April-
September 2010 over the year ago
period, on the back of steady demand
from sectors like automobile and
consumer durables. As per the
provisional data from the Ministry of
Steel, consumption was at 27.15 MT in
the same period a year ago. In Septem-
ber 2010, steel consumption rose 4.1 %
to 4.72 MT, against 4.53 MT in the year-
ago period.
Investments
A host of steel companies have lined up
major investment proposals. Further-
more, with an expanding consumer
market, the Indian steel industry is li-
kely to receive huge domestic and
foreign investments.
The domestic steel sector has attracted a
staggering investment of about US$ 238
billion, according to Mr A Sai Prathap,
Minister of State for Steel. This consists
of nearly 222 MoUs signed between the
investors and various state govern-
ments mostly in the states of Orissa,
Jharkhand, Chhattisgarh and West
Bengal.
• Tata Steel plans to invest US$
226.17 million to commission its
proposed ferroalloys plant and bar
mill at its industrial park at Gopal-
pur and a greenfield steel plant at
Kalinga Nagar.
• Essar Steel plans to expand its ex
clusive steel showrooms, Hyper-
mart and retail outlet, Expressmart
in Madhya Pradesh.
• JSW Steel plans to invest US$ 17
billion over the next 10 years to
ramp up capacity from 7.8 million
tonne per annum (MTPA) to 32
mtpa through greenfield and
brownfield projects.
• Jindal Steel has completed the ac-
quisition of Oman-based Shadeed
Iron and Steel Co LLC for US$ 464
million.
• Japan's Nippon Steel will begin a
manufacturing operation in India
making steel pipes for use in auto
mobiles and plans to invest US$ 37
million on production and sales
operations.
Government Initiative
As per the Press Information Bureau
(PIB), during 2009, the government
took a number of fiscal and administra-
tive steps to contain steel prices. Central
value added tax (CENVAT) on steel
items was reduced from 14 % to 10 %
with effect from February 2009.
Moreover, in the Union Budget 2010-11,
the government has allocated US$ 37.4
billion to the infrastructure sector and
has increased the allocation for road
transport by 13 % to US$ 4.3 billion
which will further promote the steel
industry.
Conclusion
The growth of the steel sector in India
will be robust thanks to the domestic
demand and Government Initiative.

Soon after taking charge of the Min-
istry of Steel, Virbhadra Singh, Min-
ister of Steel, interacted with repre-
sentatives from the steel industry and
took steps to implement some of their
demands. Singh set the steel industry
on the growth path with significant
growth in production.
At a time when the statistics show a much lower per capita
steel consumption in the country, what is your assessment of
the steel sector in India?
A low per capita consumption only indicates the future de-
mand potential. As you know, steel demand in the country
is pegged to the gross domestic product and its increase is
also similarly linked to growth in GDP. What we are most
interested is in improving the availability of steel in order to
cater to the growing steel demand in the country. Per capita
steel consumption will automatically improve as steel de-
mand grows and also the supply is ensured to fulfill the de-
mand.
We are also interested in improving the general steel con-
sumption through innovative design, technological and pro-
duct based solutions. There are a number of areas, where
steel usage is cost economical and can provide a better solu-
tion. These areas range from architectural buildings, airports,
railway station, flyovers, roads, etc. to rural housing and
household applications. One of our objectives is to identify
and promote innovative applications of steel in engineering,
architecture, construction and household applications.
How do you look forward to sector’s growth in terms of de-
mand and consumption over the next few years?
Over the last five years, between 2004-05 and 2008-09, steel
consumption growth in the country has been 9.6 per cent per
annum. Earlier, the National Steel Policy 2005 had estimated
an average consumption growth of 6.9 per cent. Then in
2007-08, the steel consumption growth in the country has
touched a figure of nearly 13 per cent. I believe that the ave-
rage growth of steel consumption in the country, for the next
five years, can be estimated to be higher than 10 per cent per
annum.
How do you think that the country’s annual steel produc-
tion target of 124 million tones can be achieved by 2012?
We have realistically projected a steel capacity of nearly 120
million tones in country by December 2012. Nearly 36
million tons of brownfield capacity additional projects are
going on as per schedule. Apart from this, a number of small
and medium units in the secondary sector are also coming
up fast. Except one or two Greenfield projects, we are
expecting all other steel capacity projects, as envisaged, will
be on stream by December 2012.
With the present production at 55-60 million tones, the In-
dian steel sector is the fifth largest in the world, much be-
hind China’s 500 million ton sector. How do you see China’s
role as the potential challenge to India?
The present steel capacity in the country is nearly 65 million
tons. In terms of current rate of demand growth, the steel re-
quirement in the country would double within five to six
years. Therefore, we must double our capacity within two
years to fulfill the domestic demand. Also, once our steel pro-
duction capacity is at a comfortable level, we will certainly
aim at quality and competitiveness of our steel products on
a par with the best global standards. We are continuously
watchful towards sustenance of our steel industry and take
appropriate steps, whenever, required to maintain a healthy
growth of the steel sector in India.
Now coming on China, we need to understand that every
economy has its own requirements depending upon its
supply, demand, capacity and most importantly the phase
of economic cycle it is passing through. After China, our steel
industry is the second fastest growing sector in the world in
terms of demand and production. We have become the third
largest steel producer in the year 2009, from being the
seventh largest three to four years back. We have great po-
tential for economic growth and currently our main concern
is to synergise all available resources to facilitate the pro-
duction and capacity building to meet the future steel requi-
rement in the country.

What’s your opinion on export of iron ore to other country?
Don’t you think that an increase in export duty on iron ore
will help the domestic sector to conserve it for long-term
utilization?
We are of the view that the precious raw material like iron
ore is non-renewable natural resource and should be con-
served for long-term utilization of domestic steel industry.
We are regularly taking up the issue with Ministry of Finance
for imposition of appropriate export duty on iron ore to dis-
courage its export. As a result of our efforts, export duty on
iron ore lumps has been increased recently from 10 per cent
to 15 per cent ad valorem. We feel that to effectively dis-
courage export of iron ore, we further need to increase
export duty on iron ore to at least 20 per cent ad valorem on
all varieties of iron ore.
In my opinion, I feel that the government should impose a
ban on exports of iron ore. Others may differ on this issue,
but we should see what United States and China are doing to
conserve their resource of iron ore and oil in that order.
Several international companies like ArcelorMittal and
Posco have delayed their projects due to some government’s
regulatory hurdles. What’s your opinion on this and how do
you plan to solve the issue?
Some of the greenfield projects have affected by the issue of
land acquisition. We are hopeful that there will be a political
consensus with regard to land acquisition and R&R policy. It
is a key issue not only for steel industry and infrastructure
development in general. We are hopeful of a solution.
There is no regulatory hurdle on Posco, ArcelorMittal or any
other entrepreneur planning to set up steel plants in the
country. There are certain procedural formalities and critical
requirements, especially for the greenfield projects. Since
ArcelorMittal and Posco are high capacity steel proposals
with a much larger level of integration, there are certain de-
lays. But I am sure all the hurdles will be gradually overcome
and these Greenfield will commence their executions soon.
At the ministry level, we have constituted an inter-ministerial
group, headed by Secretary, Steel with representatives from
the concerned central ministries / departments and state
governments, where major steel projects are located. This
group has been actively monitoring and coordinating on all
impeding issues and the infrastructure requirements of the
upcoming steel projects.
Rising prices have become a vital issue today, how do you
plan to check steel prices from escalating?
I keep a very close watch on prices. The recent spurt in
prices has not been a happy development. In my view that
was not warranted. We organised a meeting with major steel
producers of the country to see that there is no speculative in-
crease in prices. The results are for everyone to see as steel
prices have fallen by 5 to 10 per cent after the meeting. In a
deregulated market, the prices are determined by the inter-
play of market forces. The current rise in price of steel is at-
tributable to increase in price of steel making inputs one
hand and strong domestic demand for steel on the other
hand. Government through various policy measures tries to
maintain stability in terms of price and availability. For in-
stance, the import duty on steel has been reduced over the
years and currently stands at the lowest slab of 5 per cent.
The import duty on melting scrap has been brought down to
nil. Similarly, the general excise duty rate has been reduced
to 10 per cent which will also help in checking the rise in
price of steel.

How to Sell More Steel By: Mary House, Marketing Department
An interview with Ali Riza-Bekem and Levent Danisman
from the trading company Linkas Steel in Istanbul, Turkey
reveals the criteria one trading company uses to buy steel
from steel manufacturers.
You buy and resell steel, - who are your main customers?
Our main customers are central steel distributors in various
countries, which mainly supply the steel to the construction
companies and manufacturing industries. We trade all kinds
of steel; flats such as HRC or CRC, or longs such as reinfor-
cing bars and merchant bars. The long products consist of 70-
80% of our sales volume. A smaller amount of our business
is for the steel producers themselves; selling billets and
occasionally slabs for rolling into semi-finished and finished
products.
How do you find new customers?
We participate in a lot of trade fairs and conferences like IRE-
PAS/Steel Orbis/SBB/Metalexpert conferences and events.
We follow and pick certain markets where there is import
potential, and we visit those markets to develop relation-
ships with local players. Sometimes, we work through
agents who have a good local understanding and who are
well connected with the potential customers. Of course, we
also use the internet for locating new customers.
How is the market now in Turkey, two years after the
crisis?
The market is recovering. We see that the customers are
coming back with more inquiries. The quantities are not yet
back to pre-crisis times, and we still think it will take another
1-2 years before we reach the pre-crisis trading levels. Cus-
tomers tend to run with minimum stocks due to weaker de-
mand and market volatility.
What are the criteria your customers use to purchase steel?
For the long products, it is a very competitive market where
price and delivery time are the main determining factors. For
a product like wire rod, which is usually further processed,
quality becomes an important criteria in mill selection. For
the flat steel products which are usually intended for manu-
facturing industries, quality has a higher importance. But
still, price is the main factor when carbon steels are concer-
ned in general.
In a market down cycle, does this criteria change?
In a downturn market, on-time delivery becomes very criti-
cal as the customers tend to prefer getting the material as
soon as possible to sell it through their distribution channels
before the price drops further.
What do you see are the biggest challenges steel manufactu-
rers face today?
In the first place, due to the low demand, most mills are
operating at reduced capacities. The margins have decreased
considerably, and mill efficiency has become more important
than before. As most distributors keep lower stocks, the
order sizes have decreased. Steel manufacturers are forced to
do more size changes, which add more manufacturing costs
and lower their plant efficiency.
Raw material supply is becoming a very critical issue, too.
There were a lot of new investments prior to the crisis which
have increased the requirement for scrap. The scrap short-
age is a challenge for mini-mills.
STEEL MARKET
Ali Riza-Bekem left, Levent Danisman right
Logistics is becoming very important as well, because pre-
viously overseas shipments used to go in bulk, and now
there is a tendency towards container shipments, which re-
quire more material handling.
How do you select which steel mill to fill a particular cus-
tomer request?
Well not all steel plants make the same products. Most im-
portant is if the steel manufacturer makes the exact product
requested at a certain, price, quality and can meet the deli-
very time. If all of these fall into place, the relationship we
have with the supplier in general becomes the determining
factor as to the final mill selection.
Our job is to keep in close contact with all the steel mills at all
times so we know which mill is the best for a certain grade
and quality at the best price and delivery time. So depen-
ding on the customer´s priorities - price, delivery time,
quality, we know which will be the best mill to cover the cus-
tomers’ needs.
You may have contact with many steel manufacturers,
which supply exactly the same product. In the moment you
have an order to fill, how do you decide whom to call?
We will try to select a mill which is easier to work with in
terms of operations. We tend to go with the mills who are
faster problem solvers – in case there are any issues with the
deal they will help to solve the problems. Resolving pro-
blems such as operational issues, size changes, production
and operational flexibility are important. Long term
co-operation is also important.
Think of one of your best steel suppliers, why do you call
him more than other suppliers?
It is important in our business to have a quick reply. When
we send an inquiry we want an immediate reply. Response
time is vital in a changing market. In fluctuating markets it
has become more common that steel mills do not respect the
agreements as much and naturally we want to work with
mills who respect the agreements.
How can steel producers be more competitive?
Before the crisis it was all about cutting on already high mar-
gins. But today the margins are tight and competitiveness
will highly depend on having good technology. The specu-
lative aspect of the business in terms of raw material sour-
cing and end product sales strategies requires the mill to be
very fast decision makers and to follow the world markets
and trends, in order take the right positions. It is not enough
to be just a good steel producer today – a mill needs to be
able to read the market well, too.

QUALITY
The history of quality management is part of the history of
management itself. Initially, civilizations relied on arts and
crafts to improve the quality of the products distributed
within society.
The Industrial Revolution and the rise of mass consumption
led to emerging issues in management and specifically in
quality management. In 1924 W. A. Shewhart, a physicist at
Bell Laboratories of AT&T, developed a method for produc-
tion quality control applying statistical techniques taken
from engineering and manufacturing. Then during World
War II, W. E. Deming used these methods in the manufac-
ture of munition and other products of strategic importance.
In the mid-50s, Japan decided to make quality improvement
a national imperative in the reconstruction of its economy
based on the theories of W.A. Shewhart, W.E. Deming and J.
Juran. The Japanese worked with quality tools designed by
Deming such as control charts and continuous improvement.
It was at this time that the idea of opening a continuous
learning service came to fruition. One of its theories came
from Taiichi Ono Toyota's production manager. From the
70´s this initiative became a success mainly in the automo-
tive industry.
Since 1980, some of the U.S. states, created new organizations
dedicated to promoting quality such as the Nation Advisor
Council for Quality (NACQ). In April 1990, 21 of the largest
American companies, such as IBM, AT&T,
joined the GEMI (Global Environmental Management Initia-
tive) to begin the quality control process including environ-
mental criteria (TQEM: Total Quality Environmental
Management). This association was created in response to
the first legal measures related to the impact of industry on
health and the environment.
The standards have been progressively integrated to meet
the demands of civil society: global risks, climate change, etc.
In RUSSULA, the challenges of sustainable development
have been translated into concepts of social responsibility,
health and education.
Some milestones:
- 1970 (USA.): First quality assurance law passed for
nuclear power plant construction
- 1991 (USA.): First environmental standard (EQS) on the
quality of soil
- 1993 (USA): First environmental quality standards for
health
