Computer-Aided Process Design for Tension Levelling of Glad Sheet Metal

摘要

FE simulation of tension levelling process for clad sheet metals was performed using an elastic-plastic FE code developed by the present authors. It was found from the simulation that the elongation of the clad strip in the course of levelling is much smaller than that of monolithic strips of its component metals. The elongation and the final flatness of the clad strip are strongly affected by the strip-set condition (the situation of whether the work-roll contact layer is the stainless steel or the aluminium). Based on the numerical simulation, the optimal process design of the tension levelling was investigated for two different types of roll-arrangements.
