Abstract

The invention discloses a method for preparing a high-silicon silicon steel strip by an electric brush composite plating method. A pure iron strip, a low-carbon steel strip or a low-silicon silicon steel strip is used as a cathode plated strip, and an anode plate is plated by an electric brush. As the anode, a layer of iron-iron-silicon particle composite coating is covered on the cathodic plating thin strip through the brush composite silicon plating process to form a composite coated steel strip with the core as the steel strip matrix, and then perform uniform diffusion heat treatment to make the iron - The silicon-containing particles in the composite coating of ferrosilicon particles are uniformly diffused into the steel strip matrix at the core, thereby continuously preparing high-silicon steel thin strips. The invention also discloses a silicon steel strip continuous preparation device, which includes an unwinding guiding device, a conveying device, an electroplating device, a diffusion heat treatment device and a winding device. In the invention, the high-silicon silicon steel strip with excellent magnetic properties is obtained by electroplating the high-silicon coating on the cathode-plated thin strip, and then undergoing a heat treatment process. The method is simple to operate, has the characteristics of high efficiency and continuous preparation, and can greatly reduce the preparation cost.

Description

technical field [0001] The invention relates to a metal material preparation process and equipment, in particular to a silicon steel strip preparation process and device, which are applied in the technical field of continuous silicon steel strip manufacturing. Background technique [0002] Silicon steel is a very important soft magnetic material. It is an indispensable and important soft magnetic alloy for electric power, electronics and military industries. It is also the metal functional material with the largest output. It is mainly used as the iron core of various motors, generators and transformers. The performance of silicon steel sheets directly affects the utilization efficiency of national electric energy. Therefore, the development of high-performance silicon steel materials has very important strategic significance. [0003] High-performance silicon steel sheets require silicon steel sheets to have high initial and maximum magnetic permeability, low iron loss, and...
