Two-dimensional rolling process is modeled and analyzed by nonlinear finite element software called ABAQUS for understanding the law of changing of rolling parameters and strip tensile stress distribution in asymmetrical rolling process. There are three asymmetry factors about rolling process, drive mode, contact friction lubrication conditions between work roll and strip, asynchronous rolling mode. The effect of the asymmetry factors on the tensile stress distribution of strip, roll force and roll torque is analyzed. The effect of the asymmetry factors on the shape of strip and rolling process is compared and assessed. Simulation results show that all the asymmetry factors can make the tensile stress distribution in thickness direction of strip asymmetrical and change the mechanics parameter of temper rolling process obviously. Compared with the corresponding symmetry rolling process, some asymmetry factors can reduce the roll force and roll torque in different degree. Therefore, the advantages and disadvantages of asymmetric rolling process factors both exist from different perspective.
