Silicon steel, also known as electrical steel or oriented silicon steel, is a special type of steel specifically used in the manufacture of power equipment. Its structure has the following characteristics:
Grain orientation: The grain orientation of silicon steel is one of its most significant characteristics. The grain will be oriented in a specific direction during rolling, so that the permeability in a specific direction is maximum, thus improving the performance in the alternating magnetic field.
Amorphous regions: Silicon steel contains amorphous regions, which have a more random structure than the crystal structure. These amorphous regions help to reduce the flux loss, thereby improving the magnetic properties of the silicon steel.
Grain and grain boundaries: Grain boundaries and grain boundaries in silicon steel are interfaces between some grains with a specific orientation. These interfaces have an important effect on the electromagnetic properties of silicon steel.
Silicon content: The silicon content in silicon steel is relatively high, usually between 3.2% and 4.8%. This makes the silicon steel has good magnetic permeability.
In general, the structural design of silicon steel is designed to make it perform well in alternating magnetic fields and reduce energy loss, thus making it an ideal material for manufacturing power equipment such as transformers and motors.
