Abstract

PURPOSE:To greatly reduce the rolling load, and to make a rolling mill compact, by providing a work roll with a verical deflection preventing roll and a horizontal deflection preventing roll. CONSTITUTION:A backup roll 3 for preventing the vertical deflection of a small diameter work roll 2 is arranged; at least >=1 backup rolls 5, 4 for preventing the horizontal deflection are arranged before and after the work roll 2. Since the horizontal deflection preventing backup rolls 5, 4 are arranged before and after the work roll 2, the diameter of the work roll 2 can be shortened; besides, by employing a variable-crown type backup roll for the vertical deflection preventing backup roll 3, the rolling load is reduced, and the mill is compacted.
