Abstract:Based on experimental researches on chatter marks of steel strip of a temper mill, it was discovered that the chatter marks is closely related to self-excited vibration of the system. This kind of vibration originates from rolling interface, where partial fluid lubrication and viscous-slip coexist.
Key words: temper mill; self-excited vibration; rolling interface
