PURPOSE:To make the simultaneous disposition of roll bending means of intermediate and work rolls possible while suppressing the expansion in the window parts of a housing in rolling mills with roll bending means by disposing the respective roll bending means for the intermediate and work rolls specifically. CONSTITUTION:The projecting parts 9 of projecting blocks 7 provided in the window parts of a housing 6 freely attachably and detachably support the chocks 4 of work rolls 1 vertically movably and contain hydraulic rams 11 for bending of the rolls 1. The moving blocks 19 held movably in the same blocks 17 on the blocks 7 support the chocks 15 of intermediate rolls 13 vertically movably and contain hydraulic rams 21, 23 for bending of the rolls 13. Hydraulic rams 27 which attain equilibrium between the hydraulic rams 25 for bending of the rolls 1 and backup rolls 29 are contained in the blocks 17. Here, the end parts for holding the chocks 15 are located nearer the central side than the supporting end parts of the blocks 7. The roll groups on the lower side are of the similar mechanism. |
