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： 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： The crown (21) on a steel strip in a rolling mill is controlled by a continuous rotational adjustment of an arbor (1) in response to a control signal representing the current crown (21) profile or deviation therefrom, the arbor (1) being equipped with a series of eccentric rings (2, 3, 4, 5) fixed thereto, bearings (7) surrounding the rings, and a continuous or segmented sleeve (8) around the rings (2, 3, 4, 5). Where the sleeve (8) is segmented, use of an intermediate roll is suggested.
