Abstract：According to the chatter marks on steel strip of and supporting roll of 1220 six temper mill, continuous tracking test was carried on. Different period of a backup roll Based on analysis of the supporting roll’s vibration spectrum in different period and simulation analysis of the dynamic characteristics of the temper mill with ANSYS tools,it is found that temper mill’s main vibration frequency is 600Hz which is an abnormal vibration named the eighth order natural frequency no matter in the early or normal rolling stages.The abnormal vibration can induce chatter marks on surface of supporting roll in steady rolling stage.At last,based on the relationship of mark spacing and vibration source, the cause of temper mill’s eighth order natural frequency is found,and the control measures of chatter marks are put forward.
