In modern cold rolling, strip exit velocities of the order of thousands of feet per minute are employed. Even if only moderate reductions of the strip are performed, large amounts of heat are generated due to deformation and friction. This work presents a mathematical formulation of the problem of the temperature in the roll bite as strain rate is varied (due to Cerni), as well as some calculated examples using a typical small rolling mill. The possible influence of the temperature generated on the rolling process is also considered.
