近年来,日本三菱重工业公司开发并成功地应用了一种带钢轧机的“成对交叉”轧辊轧制技术。在常规的4辊带钢轧机中,上、下工作辊和支持辊都是垂直于轧制方向的,也即垂直于通过轧辊之间的带钢边缘。在“成对交叉”轧辊系数中,将由上支持辊和上工作辊所形成的辊对安装成和轧制方向成一角度,即和所轧钢板的上表面边缘成一角度;由下支持辊和下工作辊所组成的辊对也和轧制方向形成一

In recent years, Mitsubishi Heavy Industries, Ltd. of Japan has developed and successfully applied a “twin crossed” roll rolling technology for strip mills. In a conventional 4-roll strip mill, the upper and lower work rolls and backup rolls are both perpendicular to the rolling direction, ie perpendicular to the strip edges passing between the rolls. In the “twin crossed” roll factor, the pair of rolls formed by the upper backup roll and the upper roll are mounted at an angle to the rolling direction, ie, at an angle to the upper surface edge of the rolled steel sheet; The work roll composed of roller pairs also form a rolling direction
