Deformation Heating During Cold Rolling of Aluminum Strips

Abstract

The temperature rise due to plastic work and interfacial frictional forces during cold rolling of aluminum and steel strips is investigated. The predictions of a two-dimensional thermal-mechanical model of the process, which includes convection in the direction of rolling, are compared to measurements. The comparison reveals the exceptional predictive capability of the model. While the temperature rise in commercial cold rolling is predicted to be significant, it would be expected to contribute little to the loss of strength. Breakdowns in lubricant delivery, however, would cause excessive roll wear and should be avoided.
