Silicon Steel Sheet is an alloy, and an iron-silicon alloy formed by adding a small amount of silicon (generally below 4.5%) to pure iron is called silicon steel.
This type of core has the highest saturation magnetic induction value of 20000Gs; because of their good magnetoelectric properties, it is easy to mass-produce, the price is cheap, and the mechanical stress has little effect, and it is widely used in the power electronics industry. Such as power transformers, distribution transformers, current transformers, and other iron cores.
It is the most productive and used material in soft magnetic materials. It is also the most used material in magnetic materials for power transformers. Especially suitable for low frequency and high power.
Commonly used are cold-rolled silicon steel sheet DG3, cold-rolled non-oriented electrical steel tape DW, cold-rolled oriented electrical steel tape DQ, suitable for all kinds of electronic systems, household appliances, medium and small power low-frequency transformers and chokes, reactors, Inductor cores, these alloys have good toughness, can be punched, cut, and other processing, core lamination and winding type. However, the loss increases sharply at high frequencies, and the general frequency of use does not exceed 400 Hz.
From an application perspective, the choice of silicon steel must consider two factors: magnetics and cost. For small motors, reactors and relays, pure iron or low-silicon steel sheets are available; for large motors, high-silicon hot-rolled silicon steel sheets, single-oriented or non-oriented cold-rolled silicon steel sheets are available; single-oriented cold-rolled silicon steel is often used for transformers. sheet. When used at industrial frequency (50Hz), the thickness of the commonly used strip is 0.2~0.35mm; when used at 400Hz, it is appropriate to choose 0.1mm thickness. The thinner the thickness, the higher the price.

Cold Rolled Oriented Silicon Steel
The main purpose of cold-rolled oriented silicon steel strip is for transformer manufacturing, so it is also called cold-rolled transformer silicon steel.
Compared with cold-rolled non-oriented silicon steel, oriented silicon steel has strong magnetic directionality; it has superior high magnetic permeability and low loss characteristics in the rolling direction of easy magnetization. The iron loss of the oriented steel strip in the rolling direction is only 1/3 of the transverse direction, the magnetic permeability ratio is 6:1, the iron loss is about 1/2 of the hot rolled strip, and the magnetic permeability is 2.5 times of the latter.
High magnetic induction cold-rolled silicon steel strips are all single-oriented steel strips, which are mainly used in the manufacture of electromagnetic components such as transformers and chokes in the telecommunication and instrument industries.
There are two main characteristics of its application. One is that under the condition of low current, that is, weak magnetic field, the material is required to have high magnetic properties in the range of weak magnetic field, that is, high μ0 value and high B value; the second feature is the frequency of use High, usually above 400Hz, even up to 2MHz. In order to reduce the eddy current loss and the effective permeability under an alternating magnetic field, a thin strip of 0.05-0.20mm is generally used.
