The temper rolling is applied to eliminate the stretcher strain, to control mechanical properties, to control the surface roughness and to improve the flatness of material rolled. However, there are some unsolved problems remains in analysis of the temper rolling process. The classical rolling theories based on the rigid plastic theory, cannot deal with un-uniform elastic-plastic deformation in the temper rolling process. This paper presents elastic-plastic finite element analysis of stress behaviors in the plane strain temper rolling for annealed high carbon steel sheet. In this analysis, yield point elongation is taken into account for the stress-strain relation of the material deformed. And the calculated rolling forces by FEM are compared with the measured rolling forces by rolling experiment.
