Chatter in Cold Rolling

A basic theory of chatter in. cold rolling is presented which is based on the effect of the variable scrip tension on the rolling force as well as on the variations of contact length The structure of a computer program simulating chatter of a tandem mill is presented and examples given of the effect of rolling speed, strip width, coefficient of friction and of using a tuned damper. The paper is based on work done jointly by McMaster University and the Dofasco Steel Company.
