Abstract：Considering the influence to the dynamic characteristics of rolling force and rolling friction from horizontal vibration of rolled piece, a compensative vibration model of roll system is established. According to the Lagrange principle of generalized dissipation, dynamic equilibrium equation is established respectively both in rolling direction and in vertical direction. With four-high strip mill of a factor as an example, simulating and analyzing the horizontal vibration velocity of rolled piece and the vibration displacement of roll under different rolling speeds. Five sets of rolling force data at different rolling speeds are obtained. Finally, the theoretical values of rolling force and the test data are compared with the model before and after optimization. Research results show that: the calculated values of the rolling force after optimization are far more close to the actual working condition;
