Industrialization of New Developments in the Lubrication System of the Coupled Tandem Mill AMEKO at ArcelorMittal Eisenhüttenstadt with Henkel AG

Abstract:

In flat cold rolling of steels, emulsions of rolling oil and water are normally used to cool and lubricate, i.e. up to 2.5 % oil is emulsified in water and sprayed on work rolls and sheet. In this article it is shown how the Henkel AG and ArcelorMittal Eisenhüttenstadt GmbH developed and industrialized successfully the thin film lubrication (TFL) in front of stand one of the AMEKO. With this device, pure rolling oil is sprayed onto the work rolls. This resulted in a rolling force decrease of approx. 4.5 % in the stand and a higher operating life of the work rolls. Furthermore, the FlexMix system of the Henkel AG is presented. Therewith it shall be possible to react flexibly on the lubrication conditions in the roll gap. Using two spray bars emulsion with higher concentration is sprayed onto the strip. Trial runs were carried out in front of rolling stand number two of the AMEKO. A rolling force reduction in the stand of up to 9.7 % was seen. Moreover up to 7.9 % of less current could be observed on the motors of this stand. The article illustrates the theoretical and practical basics on both developments including effects on the production of the AMEKO. Further an outlook is given of how future lubrication techniques can optimize the production of flat steel cold rolling mills.
