Abstract

The invention discloses a method for preparing a high-silicon steel ribbon through using an electric brush composite plating method. The method is characterized in that a pure iron ribbon, a low-carbon steel ribbon or a low-silicon steel ribbon is used as a cathode plating piece ribbon, an electric brush plating anode plate is used as an anode, a layer of iron-silicon iron particle composite plating layer is coated on the cathode plating piece ribbon through using an electric brush composite silicon plating process, a composite plating layer steel ribbon adopting a steel-ribbon substrate as a core part is formed, then the uniform dispersion heat treatment is carried out, silicon-contained particles in the iron-silicon iron particle composite plating layer are uniformly dispersed into the steel ribbon substrate of the core part, and the high-silicon steel ribbon can be continuously prepared. The invention also discloses a continuous silicon steel ribbon preparing device which comprises an unreeling guide device, a conveying device, an electroplating device, a dispersion heat treatment device and a rolling device. The high-silicon plating layer is electrically plated on the cathode plating piece ribbon, then the high-silicon steel ribbon with an excellent magnetic conduction performance is obtained through using a heat treatment process, the simplicity in operation can be realized, characteristics such as high efficiency and continuity in preparation can be achieved, and the preparation cost also can be greatly reduced.

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...
