摘要： A method for producing a metal sheet with raised lines uses a rolling mill including a plurality of roll stands and produces a metal sheet including, on an upper surface, a plurality of raised lines extending in a rolling direction. The method includes a preparing step, a choosing step, an incorporating step, and a forming step. In the preparing step, a grooved roll is prepared, the grooved roll including a plurality of grooves in an outer peripheral surface. In the choosing step, a stand at least one stage before the last stand is chosen. In the incorporating step, the grooved roll is incorporated in the rolling mill as an upper roll of the chosen, specified stand. In the forming step, a workpiece is rolled by the rolling mill and is formed into a metal sheet with raised lines formed corresponding to the respective grooves of the grooved roll. At this point, in the forming step, until a leading edge of the workpiece reaches a stand next to the specified stand, a maximum rolling reduction achieved by rolls of the specified stand is set to a provisional value that is lower than a required value. After the leading edge of the workpiece reaches the stand next to the specified stand, the maximum rolling reduction achieved by the rolls of the specified stand is changed to the required value.

摘要： A compensation method of an asymmetric strip shape of a strip rolling mill, for compensating the asymmetric strip shape of a strip caused in a machining process of the strip rolling mill in the prior art. The compensation method is realized by generating a non-linear asymmetric no-load roll-shaped profile curve through polishing an upper working roll and a lower working roll of a rolling mill and forming a non-linear asymmetric no-load roll gap between a transmission side and a working side of the upper and lower working rolls. The strip rolling mill in the prior art refers to a presently commonly used two-roll rolling mill driven by the transmission side of the working roll, a four-roll rolling mill equipped with a support roll and a multi-roll rolling mill equipped with a middle roll. The present invention is applied to compensate an asymmetric no-load roll gap on the working roll, thus reducing or eliminating an asymmetric strip shape defect caused by a machining process of the strip rolling mill in the prior art and an apparent or potential asymmetric strip shape quality problem of the product caused thereby, and also reducing production stability faults such as off tracking, drifting and pack rolling caused by the asymmetric strip shape in the production process of the strip rolling mill.
摘要翻译：一种带钢轧机的不对称带钢形状的补偿方法，用于补偿现有技术中带钢轧机的机械加工过程中产生的带材的不对称带钢形状。该补偿方法是通过研磨轧机的上工作辊和下工作辊并在变速器之间形成非线性非对称无负载辊间隙而产生非线性非对称无负载辊状轮廓曲线侧面和上下工作辊的工作侧。现有技术中的带钢轧机是指目前常用的由工作辊的传动侧驱动的双辊轧机，配备有支承辊的四辊轧机和配备有轧辊的多辊轧机中间辊。本发明适用于补偿工作辊上的非对称无载辊缝，从而减少或消除了现有技术中带钢轧机机加工工艺造成的不对称带形缺陷，以及明显或潜在的不对称带钢形状由此造成的产品质量问题，并且还降低了带钢轧机生产过程中由于不对称条形造成的偏离跟踪，漂移和卷装轧制等生产稳定性故障。

摘要： The invention describes a rolling mill train (2; 30; 56) for processing rolling stock (4, 32), wherein at least three rolling stands (10) are directly adjacent in the rolling direction and are driven by electric motors (20) having superconducting windings. It is thereby possible to keep the distances between the rolling stands smaller than with conventional electric drives, thus reducing energy losses during the rolling process. A combined casting and rolling station (40), which is equipped with such an electric motor (20) in the rolling stands, is configured and/or operated efficiently in terms of the required heating power.
