Effect of lubrication in skin-pass rolling of thin steel sheets with dull finished work rolls

摘要

Skin-pass rolling, or temper rolling, is usually the final process in the production of cold-rolled steel sheets. The lubricant applied is normally a dry or soluble skin-pass lubricant with very low viscosity. Although several studies have examined lubrication conditions in skin-pass rolling, the mechanism of lubrication in skin-pass rolling has not been clarified. In the present paper, the effect of lubrication in skin-pass rolling of thin steel sheets is experimentally investigated with dull finished work rolls in two different laboratory rolling mills using relatively soft, medium-to-heavy gauge strip.
