✦ Synopsis

The mean rise in temperature with plastic strain due to the work of plastic deformation, taking account of the temperature-dependence of yield stress, is investigated when conduction effects are neglected and results for one particular example are presented. An adaptation of the well-known Siebel-I~arman analysis for sheet roiling is examined, and results for the particular case of rolling a medium carbon steel are given in detail. The temperature-dependent property of the yield stress in cold-rolling at moderate reductions is shown not to have a large effect on factors such as roll-torque, though the actual temperature increase generated is a significant one. ]Examples are given of how the temperature of the material increases in its passage through the roll gap.
