In order to solve rolling stability on roughing mills,which reduces roller accidents,one kind of varying contact-length backup roll contour curve and negatively crown work roll contour were designed and applied respectively . After the new roll system allocation was applied on roughing mill,removing harmful contact between working roll and back-up roll,uniformity contact stresses on the backup roll,large improvement the roll gap stiffness and less roll wear off is obtained,and what′s more,better strip alignment and rolling stability is helpful
