Modeling of Thin Strip Profile during Cold Rolling on Roll Crossing and Shifting Mill

Abstract

Strip profile control in cold rolling of thin strip is a difficult and challenge problem found in industry. Currently using the novel type of strip rolling mill, such as the work roll crossing and shifting is the one of the main methods to control the strip profile quality in cold rolling. In this paper, 3-D finite element simulation models of the thin strip profile in cold rolling for the work roll crossing and shifting system were successfully developed. The strip profile and edge drop are discussed considering both crossing angle and shifting value of the work rolls. The research shows that the combination of the work rolls crossing and shifting can effectively improve the strip profile. The developed 3D- finite element model has been verified with the measured values. The obtain result are applicable to control the rolled thin strip profile during cold rolling process.Keywordswork roll crossingwork roll shiftingstrip shape and profilethin stripfinite element modelingcold rolling
