Use of silicon steelFirst, in the power industry we are familiar with, oriented electrical steel can be used to manufacture power transformers. With the popularization of electronic devices and changes in lifestyles, the demand for transformers is increasing. Silicon steel has high magnetic properties and low losses, making it the preferred material for manufacturing high-quality transformers.
Secondly, silicon steel is also suitable for the transportation industry. Oriented electrical steel is used in the transportation field to manufacture motors for electric and hybrid vehicles. The quality of the motor will directly affect the performance and efficiency of the car. Good silicon
Steel Coil accessories can ensure the high efficiency and long life of the motor.
In addition, silicon steel is used in the popular electronics industry. In the electronics industry, oriented electrical steel is also used to manufacture the core of electronic equipment. The core is one of the important components in electronic equipment, and its quality directly determines the performance of electronic equipment. Oriented electrical steel has excellent magnetic properties and low loss, which can greatly improve the efficiency and reliability of electronic equipment.

Oriented electrical steel is a very pure steel with a very low carbon content. At the same time, silicon steel contains a large amount of alloy elements such as silicon and aluminum. The presence of these elements helps to improve important properties of steel such as magnetic properties, magnetic permeability, and orientation. Hysteresis loss is also an indicator to measure the performance of oriented electrical steel. The lower the hysteresis loss, the lower the energy consumption of oriented electrical steel, and the equipment can be more energy-saving and environmentally friendly during operation.
