    • In a tandem type rolling mill, it is difficult to control each roll bending force so as to produce a constant forward slip and a constant backward slip at each stand in the transversal direction.A first shape meter is disposed between a pay-off reel and a first stand and a second shape meter is disposed between a tension reel and a last stand. The roll bending forces under the first stand, the second stand, . . . the lth stand are controlled so as to produce a constant backward slip at the first stand as measured by the shape meter disposed between the pay-off reel and the first stand to provide a predetermined value.The roll bending forces under the first stand, the second stand, . . . the lth stand are also controlled so as to provide a constant forward slip at the last stand as measured by the shape meter disposed between the last stand and the tension reel to provide a predetermined value.The feeding of a roll coolant is also controlled together with the control of roll bending forces.
    • 在串列式轧机中,难以控制每个辊弯曲力,从而在横向上在每个支架处产生恒定的向前滑移和恒定的向后滑动。 第一形状计量器设置在发放卷轴和第一支架之间,并且第二形状计量器设置在张力卷轴和最后的支架之间。 第一支架下的滚动弯曲力,第二支架。 。 。 控制第l支架,以便通过设置在发放卷轴和第一支架之间的形状计量器测量在第一支架上产生恒定的向后滑动,以提供预定值。 第一支架下的滚动弯曲力,第二支架。 。 。 也可以控制第l台,以便通过设置在最后的支架和张力卷轴之间的形状计量器测量在最后的支架上提供恒定的向前滑动,以提供预定的值。 轧辊冷却液的供给也与轧辊弯曲力的控制一起控制。
