PURPOSE:To reduce the size of construction by supporting one work roll by an intermediate roll and support rolls and supporting the other work roll by an intermediate roll and divided type back up rolls in such a manner that the roll can be pushed horizontally at both sides. CONSTITUTION:The small-sized and chockless upper work roll 3 is supported by the upper intermediate roll 2 and is further supported by the support rolls 8, 9 disposed on the upper and down stream sides of a pass line 5. The small- diameter and chockless lower work roll 12 is pulled and supported by a spring 13 to the lower intermediate roll 11 and is supported by the divided type back up rolls 16, 17. The work rolls 3, 12 are supported in a manner as to offset to the down to the down stream side of the pass line 5. The fluctuation in the horizontal deflection of the work rolls 3, 12 is prevented and the shape control power is improved by such mechanism. The size of the work rolls is thus made smaller and the size of the construction smaller. |
