PURPOSE:To straighten the camber of a sheet by installing high-speed and low- speed rolls used form performing wrapping different-speeds rolling and disposing a backup roll for sandwiching a rolling stock between it and the high-speed roll. CONSTITUTION:A warpping different-speeds rolling mill has a low-speed work roll 1 and a high-speed work roll 2, and the roll 2 is made to be driven and the roll 1 is made to be driven or idle. A backup roll 3 made to be driven or idle is disposed at the upper part of work roll 2. By this construction, the camber of a rolling stock (s) produced at a gap part A between the work rolls 1, 2 by the different-speeds rolling, is straightened and removed by the equal-speed rolling of rolls 2, 3 at a gap part B. |
