PURPOSE:To rearrange rolls without biting a foreign matter and in a short time by supporting specifically inside and outside roll chocks in a rolling mill for bending shiftable work rolls. CONSTITUTION:Outside and inside roll chocks 102, 103 are set to the axial ends of upper and lower work rolls 1, (1') unmovably in the axial directions and freely turnably by a freely self-detachable clamp 106. Each roll chock is fitted to the space which penetrates lengthwise chock side frames 107, 108, and is supported freely rockably around a center line parallel to the sheet passing direction by a pair of pins 109, 110 provided to both side faces of each frame. A roll bending device 13 is engaged freely detachably with a grooved part 111 located on the roll-axis direction above which the frame is opened. Further, a roll balancing device 19 is interposed between a flange 112 at the upper side of grooved part 111 and a housing 6. A roll shifting device 5 for moving the frame 107 located at the driving side of a mill, is connected to the frame 107. Further, a stopping part for stopping the frame 107 when it moves more than a proper distance, is provided to the end part of groove 111. |
