Non-oriented silicon steel is used

Non-oriented silicon steel is a special kind of silicon steel material, which has excellent magnetic properties and low energy consumption. Non-oriented silicon steel is usually composed of silicon, iron and a small amount of carbon, manganese and other elements. It has high permeability and low hysteresis loss, and has universal applications in power transmission and conversion. The following will be a detailed introduction of non-oriented silicon steel from three aspects: material characteristics, consumption process and use.

Material characteristics

The secondary characteristics of non-oriented silicon steel include high permeability, low hysteresis loss and low iron loss. Its high permeability allows it to effectively concentrate the magnetic field and improve the transmission efficiency of power equipment. The low hysteresis loss means that less energy is lost during the magnetization and demagnetization of non-oriented silicon steel in the magnetic field, thus reducing energy waste. Non-oriented silicon steel also has excellent thermal invariance and mechanical strength, which can meet the requirements of various complex working conditions.

Consumption technology

The consumption process of non-oriented silicon steel mainly includes melting, continuous casting, rolling and annealing. Through melting, the appropriate proportion of raw materials are stopped by heating and melted to form alloy liquid. The molten metal is continuously cast into a broad band, and the broad band is processed into the desired sheet through a rolling process. By annealing process, the sheet has excellent magnetic and mechanical properties.

The use of non-oriented silicon steel

Non-oriented silicon steel is widely used in power equipment and electronics because of its unique characteristics. Here are a few common application areas:

1. Power transformer: non-oriented silicon steel is an important material for the construction of power transformers. It is used in the core sector of power transformers to concentrate and transmit magnetic fields. The high permeability and low hysteresis loss make the power transformer efficient and invariable to convert electrical energy.

2. Generator: non-oriented silicon steel on the top of the generator is used to build the rotor and stator chip. The core of the rotor and stator requires excellent magnetic permeability and low iron loss to improve the efficiency and power factor of the generator.

3. Motor: non-oriented silicon steel is also widely used in various types of motors, such as high-speed motors, meander motors, switching motors, etc. It can reduce the hysteresis loss and iron loss of the motor, and improve the efficiency and output power of the motor.

4. Isolation transformer: non-oriented silicon steel can also be used for the construction of isolation transformers. Isolation transformers are mainly used for isolation, measurement and shelter in power systems, and the high permeability and low loss of non-oriented silicon steel can improve the efficiency of isolation transformers.
