PURPOSE:To decrease the horizontal force acting on work rolls at the time of changing a rolling direction by shifting intermediate rolls without shifting the work rolls and changing the offset quantity between the work rolls and the intermediate rolls by the rolling direction. CONSTITUTION:The intermediate rolls 6, 7 are disposed between the work rolls 1, 2 and backup rolls 3, 4 at the time of rolling in a left direction in reversible type rolling. The rolls 6, 7 are movably constituted to act bending force on cylinders 18, 19 containing shift blocks 14, 15. Cylinders 16, 17 are contained the shift blocks 14, 15 provided to shaft parts 10. The cylinder 16 side is emerged and the cylinder 17 side is returned to shift the rolls 6, 7 toward the position of a broken line at the time of the ensuing rolling in the right direction. The horizontal force acting on the work rolls 1, 2 is decreased with the simple device by the above-mentioned mechanism. |
