    • PROBLEM TO BE SOLVED: To excellently control the shape while suppressing the deflection of a work roll by providing a pair of upper and lower reinforcement roll chocks which support upper and lower reinforcement rolls respectively and are movable in a housing in a vertical direction, and a driving means to shift an intermediate roll in the axial direction.
      SOLUTION: Intermediate rolls 9U, 9L, 10U, 10L of a cluster type rolling mill 3 are shifted in the axial direction, or the desired profile is given to the intermediate rolls 9U, 9L, 10U, 10L by applying the bending force by hydraulic cylinders 19L, 19U, and the load distribution becomes appropriate, and the deflection of work rolls 8U, 8L is further suppressed. Reinforcement roll chocks 14U, 14L are movable in the vertical direction in a housing 13, the work rolls 8U, 8L, the intermediate rolls 9U, 9L, 10U, 10L, and reinforcement rolls 11U, 11L, 12U, 12L are integrated with upper and lower partners, moved in the housing 13, form an extensive space in a strip 6 when the strip is passed, and the excellent strip passing is ensured.

    • 要解决的问题:通过提供一对分别支撑上加强筋和下加强筋的上加强辊和下加强辊,并且可以在壳体中沿垂直方向移动来抑制工作辊的挠曲,从而优良地控制形状,同时抑制工作辊的偏转,并且 驱动装置,用于沿轴向移动中间辊。 解决方案:集束式轧机3的中间辊9U,9L,10U,10L沿轴向移动,或者通过施加液压缸的弯曲力将期望的轮廓给予中间辊9U,9L,10U,10L 19L,19U,负荷分布适当,进一步抑制工作辊8U,8L的偏转。 加强辊轴承座14U,14L可在壳体13中沿垂直方向移动,工作辊8U,8L,中间辊9U,9L,10U,10L和加强辊11U,11L,12U,12L与上部 下部配合件在壳体13中移动时,当条带通过时在条带6中形成广泛的空间,并且确保了优良的条带通过。
