Abstract
An analytical model is proposed to analyze the asymmetrical cold strip rolling by the slab method, and used to easily determine the rolling pressure distribution, roll force, and torque. The effects of asymmetrical rolling conditions including roll speed, roll radius and friction coefficient on rolling pressure, roll force and torque are analyzed separately. The influences of different asymmetrical conditions on rolling pressure distribution are different and unrelated, but will superimpose each other when multiple asymmetrical conditions coexist. An appropriate combination of asymmetrical conditions can improve the non-uniform distribution of roll torques due to the unequal roll speed. The analysis results are in good agreement with experimental measurements and other studies, which verify the accuracy of the proposed model.
