Abstract

PURPOSE:To enable the recombination of a backup roll by arranging an actuator for work roll control between a work roll and the project block which is provided on a backup roll chock. CONSTITUTION:Actuators 13, 15 controlling work rolls 1, 1' are arranged between the project block 18 which is provided on work roll chock 12, 14 and backup rolls 2, 2' respectively. A projection is provided respectively on the work roll 12, 14, which control the shift of the work rolls 1, 1' by engaging with the hook which is motioned by a hydraulic cylinder. The recombination of the backup rolls 2, 2' by the hook for recombination is thus enabled freely with this mechanism due to no projection being provided inside the window of a housing 9. Consequently the recombination of the backup rolls 2, 2' as well as the correct shape control of the work rolls 1, 1' can be performed.
