PURPOSE:To change a rolling roll width through a remote manipulation or to perform assembly or disassembly at a short time by arranging a variable width means to adjust an interval between an operating side roll or a driving side roll. CONSTITUTION:When a driving source 17 of a variable-width means connected to the shaft end 9a of the rolling roll shaft body 9 is actuated, a nut 19 is rotated through a clutch 18, a slide block 15 engaging with this nut moves forward and backward in the axial direction with the roll shaft body 9 and, consequently, a roll interval between the driving side roll LR and the operating side roll RR or the rolling roll width to roll down the material 1 to be rolled can changed easily by the remote manipulation. When the rolling roll is disassembled from the housing of the rolling mill, important parts are supported and a gear T set to the outer surface of the case of the variable width means 13 is engaged with the gear of an assembling and disassembling device and rotated, the variable width means 13 can be removed from the rolling roll. The order should be reversed for the assembly. |
