Abstract
The vibration of the leveling mill is common in metallurgical enterprises, which causes vibration marks on the surface of the support rolls and affects the surface quality of the strip. This paper establishes a bearing-rotor system model for a leveling mill, and finds that reducing the bearing clearance helps to improve the stability of the mill. The study of different speeds under the amplitude of the change, the work of the roll system gap changes on the vibration of the mill. Finally, the results of the study can provide reference for the theory of vibration suppression of rolling mills.
