GENERALGENERAL

Rolling mill facilities are supplied with lubricants by circula-tion systems in order to ensure high product quality. If necessary, the exhaust air is also extracted and treated inexhaust air cleaning systems. As a result, spe cial emphasisis given to the handling of these media from an economicand ecological standpoint. Demands on the productionprocess relating to capacity and quality in partic ular havebeen increasing in recent years. Of decisive importancewhen it comes to meeting these requirements is, amongstother factors, the quality of the coolant technology used.

With our modern processes, products, and know-how weensure that the high level of efficiency of our rolling millfacilities is not achieved at the expense of the environment.

This brochure providesinformation on the mostimportant plants and com-ponents for correct mediahandling.

3

On the basis of our extensive scope of supply and morethan 30 years of experience, we are able to offer solu tionsfor almost all problems arising when dealing with thesemedia.

Our services range from supplying components to reva mp -ing and supplying complete circulation systems as well asto providing consulting services. In addition to our broadarray of services and experience, the number of our refer-ences is also worthy of note. We have designed and builtover 600 filters and separators and over 700 coolant sys-tems for our customers around the world.

COOLANT SYSTEMSCOOLANT SYSTEMS

PLANTS

Essentially the task of the coolant system is to feed themedium to the service points with the correct pressure,temperature and purity and to discharge and treat thismedium after use. This process occurs in an almost closedcircuit.

In the circulation systems the coolants are treated with various filters and separators from our broad array of filterproducts. The decisive criteria for chosing the right filterare:

type of coolant usedrequired puritytype and degree of pollution

Rolling oils and rolling emulsions are coolants which,depending on their conditions, can have a significant effecton product quality.

In addition to various types of precoat filters for the filtra-tion of rolling oils, our filter line also includes, for example,the Supafine filter which operates without filter aids.


6

In addition to coolant systems, our scope of supply alsoincludes coolant treatment lines. The thermal treatment of the rolling oil is effected by our compact distillation system, Oildist. By combining the thermal separation technique with ultrafine mechanical filtration, a constantand optimum rolling oil quality which is free of foreign oilsis ensured. Moreover, the life of the rolling oil is extendedthereby, which in turn results in considerably lower operat-ing costs.

Furthermore, we also offer you a concentration measure-ment system for automatic measurement of the oil concen-tration in emulsions. In this system, other parameters suchas temperature and density are also determined.

Together wit our affiliated company SMS Lubrication weoffer rolling oils and emulsions to meet the ever increasingdemands of the rolling mill industry.

EXHAUST AIR CLEANING SYSTEMSEXHAUST AIRCLEANING SYSTEMS

A great variety of systems are used to treat the different waste air flowsoccurring in the metallurgical industry. All systems are designed to clean thewaste air so that it can at least be discharged into theatmosphere safely in accordance with environmental regu-lations.

Owing to an effective extraction system and enclosure ofthe mill stands as well as to optimal design of the waste aircleaning system, minimum operating costs are incurred.

A particularly economical solution for exhaust air cleaning is the AIRWASH system, which is based on the absorption/rectification procedure and reclaims the rolling oil from thewaste air flow. The reclaimed rolling oil can then be feddirectly into the rolling oil system. The cleaning perform-ance of the system itself meets the most stringent envi ron -mental legislation, even when a high percentage of oil ispresent in the form of gas. The performance of the airwashsystem is especially suited for rolling mills with high rollingspeeds (e. g. 6-high rolling mills).
