PURPOSE:To make working and assembling easy and to improve the rigidity of the housing of a rolling mill by disposing respectively hydraulic jacks between a work roll chock and a backup roll chock and between said housing and the backup roll chock. CONSTITUTION:A work roll chock 23 is supported so as to be held by the top end of a backup roll chock 25, and a hydraulic back 27 for bending roll is provided between both chocks 23 and 25. A hydraulic jack 29 for crossing roll is provided between the chock 25 and a cross beam 28 mounted to a housing 26. The jacks 29 facing each other with the chock 25 in-between are cooperatively operated. On the other hand, both ends of the rolls and the upper and lower rolls are made respectively opposite in direction. Then the rolls 22, 24 are crossed in the direction at a right angle to the feed direction of a material 21 to be rolled and in opposite directions within the plane parallel with the rolling plane of the material 21. |
