    摘要： This invention provides a rolling method and a rolling apparatus, for flat-rolled metal materials capable of stably producing flat-rolled metal materials not having, or having extremely little, camber. A rolling method for a flat-rolled metal material uses rolling equipment including a rolling mill and at least a pair of pinch rolls for clamping a rolled material on the exit side of the rolling mill having a mechanism in which either one, or both, of upper and lower roll assemblies have a mechanism for supporting a work roll by split backup rolls split into at least three segments in an axial direction, the split backup roll group having a construction for supporting both a vertical direction load and a rolling direction load acting on the contacting work roll and each of the split backup rolls independently having a load measuring device. The method comprises the steps of directly measuring, or calculating on the basis of a predetermined measurement value, either one, or both, of left-right balance of a rolling direction force acting on a rolled material from the pinch rolls and the left-right balance of a rolling direction force acting on the work roll of the rolling mill through the rolled material; and controlling a left-right swivelling component of a roll gap of the rolling mill on the basis of the measured value or the calculated value of the left-right balance of the rolling direction force.

    摘要翻译： 本发明提供一种轧制方法和轧制设备，其能够稳定地生产不具有或极少弯曲度的扁平轧制金属材料。 用于扁轧金属材料的轧制方法使用轧制设备，所述轧制设备包括轧机和至少一对用于夹紧轧制机出口侧的轧制材料的夹送辊，所述轧机具有其中一个或两个 上部和下部辊组件具有用于通过在轴向方向上分成至少三段的分割支承辊来支承工作辊的机构，所述分离支承辊组具有用于支承垂直方向载荷和作用于其上的轧制方向载荷的结构 接触工作辊和每个分割支承辊独立地具有负载测量装置。 该方法包括以下步骤：根据预定的测量值直接测量或者根据预定的测量值计算从夹送辊作用在轧制材料上的轧制方向力的左右平衡中的一个或两个，以及左右平衡 通过轧制材料作用在轧机的工作辊上的轧制方向力的平衡; 并且基于测量值或轧制方向力的左右平衡的计算值来控制轧机的辊缝的左右旋转分量。
