Abstract Base on no hydraulic roller bending device on medium plate mill, Roll Wear Coordination Distribution Method is introduced so as to prevent strip shape problems by traditional equal load distribution. It analyses the influence to strip shape by roll crown, and real-time roll crown is obtained by soft sensor models of roll thermal crown and roll wear. Strip shape coefficient is adjusted in response to the change of roll crown in order to get more rational load distribution schedule and better effect of strip shape. From application results it shows that strip shape problems such as intermediate shape and side shape decrease obviously after this method starts, and it has a great application value.
