PohangSteelworks

Pohang WorksPohang Works was the rst integrated steel mill ever built in Korea. This

grandiose project by Yeongil Bay started with Phase 1 being

commissioned in 1973, and spanned three more phases until its

completion in February 1981. It currently runs carbon steel and stainless

steel processes and has played a pivotal role in promoting POSCOs

global competitiveness with the establishment of the worlds rst

commercialized Finex process in May 2007.

Major Products

Hot- and cold-rolled steel, plates, wire rods, electrical steel,

stainless steel, API steel, etc.

PH-CoreThe directional property of grain-oriented electrical steel is more reinforced in the rolling direction than PG-Core and therefore fea-tures lower core loss and higher magnetic ux density. It is used for iron core of both large and other size power transformers anddesirable for high efciency and miniaturization of m achinery.

PHD-CoreMagnetic domain rened steel is the product that has been specially treated with laser scribing to lower the core loss about 30% fromthat of CGO steel. Energy efciency is highered and magnetostriction is lowered, resulting in low noise of this domain rened steel.It is used for iron core of both large and othersize power transformers that have not been heat treated.

Non Grain-OrientedElectrical Steel

PN-CoreThe non-oriented electrical steel features even magnetic properties in the rolling direction and in other directions.They are widely used for iron core materials of rotating machines ranging from large-size power generators to small-size precisionelectric motors. They are also desirable for iron core of small-size power transformers.

Stress relief annealing is a process that is carried out to acquire desired magnetic properties of electrical steel sheets

by relieving stress generated in the process of shearing and punching at a proper temperature for a certain period of

time.

Annealing Temperature

If the annealing temperature is too low, it is difcult to acquire adequate magnetic properties and if the temperature is too high, it may

erode surface insulation and degrade insulation properties.

The optimum annealing temperature for grain-oriented electrical steel is 780to 840and 750to 800for non-oriented electri-

cal steel for improved magnetic properties.

Annealing Time

Annealing time means the in-furnace time of materials at the highest temperature during the annealing process. During this time, the

materials in the furnace should be evenly heated. The annealing time varies depending upon amount of materials or type of furnace.

Generally, the annealing time is between 1.5 to 2. 5 hours.

Heating and Cooling Speed

Abrupt heating and cooling must be avoided to prevent any deformation of the iron core. Slow cooling must be applied until it

reaches 300~350, after that and cooling is permitted.

Furnace Atmosphere

Furnace atmosphere should be controlled to minimize carburization or oxidization which can diminish magnetic properties.

Therefore a pure nitrogen atmosphere is ideal and the dew point of gas should be maintained as low as possible, below 0 is

adequate.

The oil used in shearing and punching should be removed completely. Otherwise both sides of piled-up core will be damaged during

the annealing process, deteriorating the work capacity.
