Abstract

The invention discloses a method for producing thin-gauge medium-high-grade non-oriented silicon steel by a CSP flow anomalous process, and belongs to the technical field of silicon steel production. The invention includes the following steps: composition design, smelting, CSP continuous casting, tunnel furnace soaking, hot continuous rolling, cold rolling and annealing. Through composition and process design, the present invention can effectively overcome the disadvantages of corrugated defects in high-grade grades in the existing CSP production, and omit the normalization process of the conventional process, so that the produced thin-gauge non-oriented electrical steel has high magnetic induction and low iron loss excellent magnetic properties.

Description

technical field

[0001] The invention belongs to the technical field of silicon steel production, and more particularly relates to a method for producing thin-gauge, medium- and high-grade non-oriented silicon steel by a CSP process irregularity process. Background technique

[0002] Non-oriented silicon steel is the most widely used soft magnetic material in motors, and it is one of the key materials that constitute the core components of motors. Its magnetic properties directly affect the efficiency of motors. The use of high-efficiency non-oriented silicon steel is one of the main ways to reduce volume, weight, iron loss and improve efficiency of electromechanical products. With the country and society increasingly demanding and paying more attention to environmental protection, energy saving and consumption reduction, electromechanical products are constantly developing towards miniaturization and high efficiency. The development of high-efficiency non-oriented silicon st...
