2021 1 1 Cold rolling plays a crucial role in flat steel production. In recent years, it has become extremely difficult to ignore the existence of chatter, also called ghost vibration by operators who work in milling plants, which restricts the quality and efficiency of strip production.Fig. 1 shows the layout of a tandem cold rolling process. Mill vibration often occurs in stand 4 and 5
