Abstract：

For cold rolling mill of an iron and steel company, the influences of electrical control system parameters on product quality of strip steel and on vibrations of rolling mill were analyzed. Then, the rolling process of rolling mill was simulated based on MATLAB/Simulink module and a theoretical analysis method, and the simulation diagram of the compression rate and the tension fluctuation versus the strip quality and the vibration of the rolling mill respectively were obtained. It is proved that the compression rate could cause the change of the plate crown and the vibration of the rolling mill and the tension fluctuation influences the vibration of working roll. The main factors causing the vibration of rolling mill are the compression rate and the tension fluctuation, and the vibration suppression of the rolling mill can be achieved by optimizing the electrical parameters and improving the tension control method.
