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.
