Silicon Steel Sheet

In 1900, R.A. Hadfield and others from the United Kingdom first discovered that Si-Fe alloy containing 4% Si has good magnetic properties. In 1903, Germany and the United States successively produced hot-rolled silicon steel sheets containing Si1.0~4.5%. In 1906, it was used to make motor and transformer cores instead of mild steel. In 1934, the American N.P. Goss used two cold rolling methods to produce (110)  cold-rolled silicon steel sheets containing Si3% with preferential grain orientation. In 1968, Japan's Taguchi Satoru and others used comprehensive inhibitors of manganese sulfide and aluminum nitride and used a large reduction rate cold rolling method to make (110)  high magnetic induction oriented silicon steel. The grain orientation of this material is more accurate. , iron loss and magnetism are further improved. Over the years, the schematic curve of the decrease in iron loss value of silicon steel is shown in Figure 1.

In 1949, the United States produced cold-rolled (110) oriented thin silicon steel strips with a thickness less than 0.1mm for use in the electronics industry. In 1957, the Federal Republic of Germany produced (100)  cubic oriented silicon steel sheets, which have high magnetic properties in both longitudinal and transverse directions. However, due to the complexity of the process, they have not yet been officially produced. Figure 2 is a schematic diagram of the grain arrangement in (110) and (100) oriented silicon steel sheets. The magnetostriction of Si-Fe alloy containing 6.5% silicon is about zero, with high magnetic permeability, low iron loss, and the made transformer is noiseless. However, it is not widely used due to difficulty in processing. In the 1970s, liquid rapid cooling technology was used to produce 6.5Si-Fe microcrystalline thin strips, and new varieties such as thinner oriented silicon steel sheets and silicon steel sheets with (100) plane texture (no intergranular orientation) were developed.

Function Of Silicon Steel Sheet In Transformer

The common transformer core is generally made of silicon steel sheet. Silicon steel is a kind of steel containing silicon (silicon is also called silicon), and its silicon content is. 0.8%~4.8%。 The reason why silicon steel is used as the iron core of transformer is that silicon steel itself is a magnetic material with strong magnetic conductivity. It can produce large magnetic induction intensity in the energized coil, which can reduce the volume of transformer. The power loss of transformer under AC state is not only on the resistance of coil, but also in the iron core under alternating current magnetization. The power loss in the iron core is usually called "iron loss", which is caused by two reasons, one is "hysteresis loss" and the other is "eddy current loss".
