Abstract

The invention relates to the technical field of steel rolling, in particular to a method for raising the transverse thickness difference of high-grade non-oriented silicon steel, comprising: presetting a target crown value compensation value and a compensation position in a rolling plan sheet in a rolling model, wherein the compensation position is 1, 2, 3... N, and N is a positive integer. The actual value of the target crown value is calculated and input into the rolling model, and the rolling process of the steel block is controlled by the rolling model. The method for raising the transverse thickness difference of the high-grade non-oriented silicon steel provided by the embodiment of the invention improves the control level of the transverse thickness difference of the low-speed whileensuring the rolling stability.

Description

technical field [0001] The invention relates to the technical field of steel rolling, in particular to a method and a device for improving the control level of lateral thickness difference of high-grade non-oriented silicon steel. Background technique [0002] High-grade non-oriented silicon steel products are used in the manufacture of large motors (such as large generators, large AC and DC motors, etc.), energy-saving home appliances (such as inverter air conditioners, refrigerators, etc.), core components of electric vehicle power systems, and small and medium-sized high-efficiency motors. Indispensable and important material, mainly used as stator punching, the lateral thickness difference is the key quality index. Cold-rolled high-grade non-oriented electrical steel has the characteristics of high silicon content, high deformation resistance, and high cold-working brittleness. Under the same cumulative deformation rate, the yield strength of high-grade non-oriented sil...
