Abstract: According to the chattermarks on steel strip of HC cold rolling mill , continuous tracking measurement is adopted.By analysysing and compairing with the collected vibration and simulation analysis on natural characteristics of rolling mill,it is found that chattermarks of steel strip mainly cuased by the 7th natural frequency.lAt ast, combining chatter marks spacing with vibration frequency ,for analysising cuase of chatter marks on steel strip ,the cause of the cold rolling mill vibration is found,this article put forward relevant inhibiting chattermarks measures.and the measures are used for production,that got a good inhibition chatter marks result.
