Skin-pass rolling (or temper rolling) is usually the final process in the production of cold-rolled steel sheets. In operation, skin-pass rolling is performed with a lubricant with very low lubricating ability. However, relatively few studies have been reported in the literature regarding the effect of lubrication in skin-pass rolling.

Cold rolling cannot reduce the thickness of a workpiece as much as hot rolling in a single pass. Cold-rolled sheets and strips come in various conditions: full-hard, half-hard, quarter-hard, and skin-rolled. Full-hard rolling reduces the thickness by 50%, while the others involve less of a reduction.
