A silicon iron alloy. Rolling with the silicon steel sheet is in the field of application of electrical most of the soft magnetic materials, thus silicon steel sheet also known as electrical steel. Silicon steel sheet widely used in motors, generators, transformers, chokes, electromagnetic, and measuring instruments in the relay. Silicon impact of the performance of silicon steel sheet. Silicon steel is a good Deoxidizer. It and oxygen combine to make changes for the stability of oxygen for carbon reduction is not the SiO2, to avoid a doping due to oxygen atoms iron lattice distortion. Α in silicon iron in a solid solution to resistivity after the sharp rise at the same time contribute to harmful impurities will be separated from the carbon. Therefore, the general containing impurities in silicon after the accession of iron can increase permeability rate and reduce coercivity and iron loss, but will also increase the volume of silicon material hardens Biancui, thermal conductivity and toughness decline in the thermal and mechanical processing Unfavorable, the general silicon steel sheet of silicon content of not more than 4.5 percent. Carbon, sulfur, oxygen is considered silicon steel sheet in the three evils. These elements will increase soft magnetic materials of coercive force, silicon steel sheet and increasing loss of hysteresis. In addition, nitrogen will prevent excessive growth of grain, led to hysteresis loss and coercive force increase. Al excessive (more than 0.5 per cent) of silicon steel sheet too brittle, it is difficult to process. Therefore, these should be eliminated on the silicon steel sheet have an adverse effect on the impurity elements. Cold-rolled silicon steel sheet or also known as grain oriented silicon steel sheet steel Goss texture, is the first in 1934 by the NP Goss made a cold-rolling method. It has an excellent along the rolling direction of the magnetic properties. Grain-oriented texture steel not only in strong magnetic field has a high saturation magnetic flux density and low iron loss, but also in weak magnetic field has a good magnetic (initial permeability of large). This is due to cold-rolled steel in the process to reduce the content of impurities, and in a large steel grain. Coarse grains will permeability rate increased, decreased hysteresis loss. Cold-rolled steel grain to the edge of the cube (the most vulnerable magnetization direction) along with rolling direction, is conducive to the conduct of magnetization. This material known as the single-oriented silicon steel sheet. Is also able to create more easily magnetized direction of the silicon steel sheet (that is, non-oriented silicon steel sheet). Industrial large-scale use of electrical thickness of 0.35 ~ 0.50 mm of silicon steel sheet in telecommunications technology commonly used in high-frequency 0.05 ~ 0.20 mm strip of thin films, in order to more effectively reduce the eddy current losses. Hot-rolled silicon steel sheet thickness of 0.35 ~ 0.50 mm, density of 7.55 ~ 7.70 g/cm3, and more for large, medium and small pay, the DC motor; cold-rolled non-oriented silicon steel sheet thickness of 0.35 ~ 0.50 mm, density of 7.65 to 7.75 g/cm3, and more for large-scale exchange of generators, motors, large, medium and small pay, the DC motor; cold-rolled silicon steel sheet thickness of single-orientation of 0.35 mm, density of 7.65 g/cm3, and more for electricity transformer, reactor, magnetic Amplifiers; orientation of cold-rolled thin strip single thickness of 0.05 ~ 0.20 mm, and more for high-frequency radio transformer.
