Abstract

The invention discloses an electrical steel lateral thickness difference control system and a method of the control system, and belongs to the technical field of steel rolling. The system comprises a thickness multi-point comprehensive evaluation module and an edge falling flexible control module, and further comprises a first coupling module. The invention is aimed at flaws generated during the actual production process in terms of the lateral thickness difference control, improves level of controlling the electrical steel lateral thickness difference, and moreover improves capability of a rolling mill for controlling straightness of strip steel and improves stability of the rolling.

Description

technical field [0001] The invention belongs to the technical field of steel rolling, and in particular relates to a control system and a method for lateral thickness difference of electrical steel. Background technique [0002] Due to the needs of the processing characteristics of electrical steel laminations, the transverse thickness difference of the strip determines the lamination coefficient of the electrical steel. Therefore, in order to improve the efficiency of the motor, the user not only has strict requirements on the electromagnetic properties of the electrical steel, but also has strict requirements on the transverse thickness difference. Extremely high (ordinary requirements are less than or equal to 10um, and advanced requirements are less than or equal to 5um). Therefore, the strip transverse thickness difference has become an important quality index of cold-rolled finished electrical steel, and the key factor affecting the strip transverse thickness differenc...
