Abstract By site testing and data analyzing for F2 and F3 stands which vibrate more seriously, it was found that the frequency of the chatter marks is equal to the vibration frequency. The calculation result shows that the length of chatter marks on the roller and strip transferred on to rolling interface is equal to the contact arc length, which indicates that there is a direct relation between the chatter marks and the contact arc. Based on such observation, a mechanism of mill vibration was constructed. During the rolling process, chatter marks on the work roller are spreading from initial marks,making the mill vibration aggravated. This mechanism was supported by monitoring data,and is important for vibration prevention on same kind of mills.
