As a common defect in the production of high-quality steel strip, chatter marks are easily found on the strip surface which may resulting from inappropriate variation of rolling parameters of a twenty-high rolling mill and the quality of the strip surface can be significantly affected. Therefore, it is critical to understand the underlying relationship between the vibration mechanisms of chatter marks and rolling parameters, furthermore, an appropriate adjustment strategy of rolling parameters is needed to improve the quality of the strip surface. To addressing this problem, a dynamic model of the twenty-high rolling mill, coupling the vertical and horizontal vibrations (because of the variation in friction tension forces), is proposed to investigate the vibration characteristics under different rolling conditions. Based on this dynamic model, effects of rolling force, rolling speed and fluctuations of tension on the vibration of the twenty-high rolling mill are studied. Finally, a rolling parameter adjustment strategy is discussed and presented based on the research results.
