PROCESS FOR IMPROVING THE ADHESION OF A LUBRICANT TO THE SURFACE OF AN ALUMINIUM STRIP

摘要

A process for improving the adhesion of a lubricant to, and the distribution on, the surface of a strip of aluminium or aluminium alloy which is cold rolled between two work rolls, said cold rolled strip being coated with lubricant for the purpo se of subsequent shape-forming, is such that the surface of at least one work roll exhibits a roughness pattern (10), which is comprised of at least two line patterns (14,18) that cross each other, whereby each of these line patterns is characterised by a plurality of parallel rills (12,16).
