DEVICE AND METHOD FOR SHIFTING WORK ROLL OF CLUSTER MILL
A roll shifting cylinder (14) is driven to pivot a lever arm (12), thereby shifting a work roll (1) via a thrust bearing (15). A control unit (27) performs auto-positioning control, based on a shift amount performance value of the thrust bearing (15) detected by a shift amount detection sensor (16),...

| description | A roll shifting cylinder (14) is driven to pivot a lever arm (12), thereby shifting a work roll (1) via a thrust bearing (15). A control unit (27) performs auto-positioning control, based on a shift amount performance value of the thrust bearing (15) detected by a shift amount detection sensor (16), so as to obtain a target roll shift position. A constant clearance amount is maintained between an end surface of the work roll (1) and the thrust bearing (15) during a rolling operation, and a chockless mill is effectively used as a work roll shift mill. |
