Abstract：In order to find the regularity and mechanism of vibration of CSP mill during rolling thin container strip, torsional vibration of main drive, vertical vibration of stand and suppression measures of three intermediate stands were tested in spot. Then the relationship between strip(roller) chatter marks and technological parameters, and vibration of rolling mill, and necessary conditions for chatter mark generation were researched. It was found that the frequency of F2 roller chatter mark is 14 Hz, and which is caused by torsinal vibration of main drive system excited by transfer case mesh impact. The frequency of F3 roller chatter mark is 54 Hz, which is caused by horizontal vibration of roller system excited by spindle curved tooth mesh impact. The frequency of F4 roller chatter mark is 78 Hz, which is caused by stand horizontal resonance vibration. For F4, to avoid chatter mark growing, it is necessary to select work roll diameter cautiously at preset rolling speed. The contrast test indicated that the vibration can be eliminated by stopping oil water emulsion supply and adopting highspeed steel work roller.
