Abstract：

For a series of poor quality issues that caused by unknown vibrations of Hanbao cold rolling mill during the production process in Handan Iron and Steel Company, dynamic model and mathematical model were established based on the F4 rolling mill that vibrated most frequently. Each natural frequency of system was gained through analyzing and calculating by MATLAB. Compared with the excitation frequency gained by field testing, it is found that the cause of torsional vibration is in the main drive system. The result shows that the main reasons of torsional vibration are the main drive electrical control systems, load changes, rolling slip and gap impact. Furthermore, the suggestions about the inhibition torsional vibration were put forward, which provided a theoretical basis for analyzing torsional vibration of cold rolling mill in future.
