Ensuring Specified Surface Roughness in the Production of Thin Cold-Rolled Steel Sheet

Abstract

The formation of surface microrelief on rolled strip is considered. The influence of the surface state of the rolls, the strip reduction, the rate of reduction, the mechanical properties of the metal, the lubricant employed, and other rolling and tempering parameters on the roughness of cold-rolled steel strip is analyzed. Practical means of ensuring compliance with the surface-roughness standards for thin sheet are proposed.
