ROLL SPEED MAPS FOR HOT ROLLING PROCESS DESIGN

Abstract

In metal forming processes, the behavior of the metal undergoing large plastic deformation is affected by the dynamic or strain rate effects of the material. Since both of' the material and mechanical effects are correlated with each other in the forming processes, they are effectively treated by the computer simulation which can take account of strain rate effect. The dynamic material modeling (DMM) is a proven technique for studying constitutive behavior of materials. In this study Roll Speed Maps (RSM) are generated using simulation and DMM, which are used to select the optimum roll speed for different frictional conditions.
