Insulated and anti-corrosive I type silicon steel sheet and heating method thereof

Abstract

The invention relates to an insulated and anti-corrosive I type silicon steel sheet. The insulated and anti-corrosive I type silicon steel sheet is characterized by comprising a silicon steel sheet body (1); the silicon steel sheet body (1) is 0.4-0.6 mm in thickness, 2000 m in length and 1 m in width; the silicon steel sheet body (1) is I-shaped model; the surface of the silicon steel sheet body (1) is orderly coated with an insulation layer (2) and an anti-corrosive layer (3). The insulated and anti-corrosive I type silicon steel sheet and the heating method thereof can well use materials in the process of production and shearing; the material layout utilization rate is 100%, and no waste generates; meanwhile, copper wires are coiled between the gap of the silicon steel sheet, thus alternating current magnetic field can be generated, and current is induced from a secondary coil. Meanwhile, the surface of every silicon steel sheet is coated with the insulation layer and the anti-corrosive layer, and thereby improving the insulation property and the corrosive resistance of the silicon steel sheet; meanwhile, the silicon steel sheet applies an improved heating method, thus the process is simple, the energy source is saved, and cost is relatively low.

Description

technical field [0001] The invention relates to a silicon steel sheet, in particular to an insulating and anti-corrosion I-type silicon steel sheet and a heating method thereof, belonging to the technical field of electromechanical. Background technique [0002] Silicon steel sheet is a kind of silicon-iron soft magnetic alloy with extremely low carbon content. Generally, the silicon content is 0.5-4.5%. Adding silicon can increase the resistivity and maximum magnetic permeability of iron. It is mainly used to make various transformers, motors and The iron core of the generator. [0003] The traditional silicon steel sheet for motors has a C-shaped cross-section, which cannot make good use of the material during the production and cutting process, and the material discharge utilization rate is 100%, resulting in a lot of waste. At the same time, the insulation and anti-corrosion properties of silicon steel sheets in the past are relatively poor; at the same time, the silico...
