Abstract

PURPOSE:To prevent the unbalance of screw-down reaction force, and to automatically control the plate thickness and a snake motion, by coupling upper and lower inner-housings for supporting upper and lower rolls so that they can be moved relatively. CONSTITUTION:This cross-rolling mill consists of an upper work roll 2, an upper backup roll 4 which is in contact with its upper side, supporting parts 12, 12' of the roll 4 which is in contact with a screw-down means of reduction screws 9, 9', a lower work roll crossed at a prescribed angle to the upper rolls 2, 4, a lower backup roll 5 which is in contact with its lower side, also an upper inner housing 11 for supporting the upper rolls 2, 4 so that they can be moved up and down, and a lower inner-housing 13 for supporting the lower rolls 3, 5 so that they can be moved up and down. Said upper and lower inner-housings 11, 13 are coupled so that they can be moved relatively in the upper and lower directions and the rolling direction. According to said rolling mill, the unbalance of screw- down reaction force is prevented, and the plate thickness and a snake motion are controlled automatically.
