On the feasibility of surface-film lubricated cold rolling without liquid-phase cooling

This tech brief presents some basic theory and calculations to help assess the feasibility of surface-film lubricated dry skin pass of metal strips to enhance surface finish after cold-rolling operations. Results are presented of the required rate of heat removal from the rolling apparatus and the maximum rise of roll surface temperature for steel and aluminum strips under various parametric conditions of practical interest. The theory and the calculation tool may be used to perform analyses with other material, geometry, and operating parameters and to assist the design and development of surface-film lubricated dry skin-pass processes.
