Abstract: The vibration theory of strip rolling mill has always been a scientific problem in the field of rolling forming, which is very important to the quality of sheet metal and the stable operation. With the rapid development of rolling mill towards large scale, high speed, continuous and intelligent, as well as the adoption of a large number of new technologies and new processes, the research on rolling mill vibration has gradually developed from the single attribute study to polymorphic coupled vibration, and from linear vibration to nonlinear vibration. The study of rolling mill vibration theory depends on the precise control of rolling mill vibration in addition to the reasonable structure model. In order to fully understand the dynamic behavior and vibration characteristics of strip rolling mill and obtain reasonable and feasible control strategy, the research status of vibration theory of strip rolling mill at home and abroad is summarized from the aspects of unidirectional vibration, multistate coupling vibration and nonlinear vibration, and the application status of active control method and passive control method in rolling forming process is analyzed. Considering the current development trend of steel industry, the future research direction of strip rolling mill is prospected.

Key words: strip rolling mill, unidirectional vibration, polymorphic coupled vibration, nonlinear vibration, vibration control
