Prediction of Proper Horizontal Position of Work Roll in Backup Roll Driven-type Cold Rolling Mill

보강롤 구동 냉간압연기에서의 적정 작업롤 수평위치 설정기법 개발

For the purpose of rolling hard metals such as silicon steel and non-ferrous metals, the backup roll driven-type mill has been widely used in cold rolling industry. Since the backup roll drive results in horizontal bending of the work rolls and therefore exerted reciprocal action on the roll gap contour, the selection of slim work rolls is very restricted. In this paper, we present an analytic equation based scheme to determine a proper horizontal position of work roll minimizing the horizontal force subject to mechanical constraints.
