Abstract：

For the vertical vibration phenomenon of cold rolling mill, combining recent achievements of mill vertical vibration problems, it was concluded that the roll gap is the source of cold rolling mill vertical vibration. When the cold rolling mill rolled at high speed, the change of roll gap lubrication led to the change of roll gap damping and vertical vibration of rolling mill. A simplified model of cold rolling mill was built, and the cold mill rolling process was simulated. Furthermore, the relationship between roll gap damping and vertical vibration mill was analyzed, and the conclusion was made that mill vertical vibration is due to roll gap damping reducing. The proper roll gap damping is maintained by increasing the roll gap friction coefficient and additional damping device, the vertical vibration is eliminated, and the smooth running of mill is ensured.
