PURPOSE:To move stably a slide base in the stage of roll changing, etc. by bringing the slide plate which moves only in the vertical direction on the side face of the stationary base of a cross rolling mill into contact with the lower inside surface of the slide base so as to be positioned at the line center of the rolling mill. CONSTITUTION:A bottom beam 16b intervened with a slide base 14 below the lower backup roll 3b of backup rolls 3a, 3b circumscribing work rolls 2a, 2b and a pair of upper and lower jacks 13a, 13b for cross head in contact with both side walls of backup roll chocks 7a, 7b are installed in a housing 8. A guide plate 28 movable only in the vertical direction on the side face of a statonary base 22 in the lower part of the housing 8 is freely attachably and detachably brought into contact with both inside surfaces in the lower part of the base 14 so as to be positioned at the center of the rolling mill. The horizontal movement of the base 14 in the stage of roll changing and the horizontal turning motion in the stage of roll cross operation are smoothly accomplished and the online polishing of the rolls is made possible. |
