Computational Model of Work Roll Temperature Distribution during Hot Strip Rolling Process

摘要: Computational models of deformation and friction work were established by dividing contact arc between strip roll into two sliding regions, braking regions one stagnating region. A dimensional temperature field model was finite difference method according to practical boundary conditions. Simulation results show that with the increase rolling pass, reduced while increased, except works at last pass least. The computed forces surface temperatures agree well measured values collected from a hot mill.
