High magnetic induction and low iron loss cold rolled oriented silicon steel sheet is an urgent product in power industry. The higher the magnetism of the silicon steel sheet, the electrical appliances manufactured are: less power loss, small size, light weight, long service life, and less cooling oil for the manufactured transformer. In particular, it can solve the problem that large electrical appliances such as transformers larger than 360000 KVA use lower magnetism. Difficulties of oriented silicon steel sheet manufacturing and transportation cannot pass through railway tunnels and highway bridges.

Non-oriented silicon steel is used in rotating equipment such as motors. It is divided into iron core and rotor. In order to be easily magnetized during the rotation process, electrical energy is converted into mechanical energy. Therefore, it is required to be easily magnetized at every angle in the rotation process, so the grain orientation distribution in the non-oriented silicon steel is required to be uniform.

Non-oriented electrical steel is mainly used as the iron core of large and medium-sized motors, generators, household motors and micro-motors, ballasts and small transformers. The main magnetic performance requirements of non-oriented electrical steel are low specific total loss and high magnetic polarization. The low specific total loss can save a lot of electric energy and extend the working time of the motor. High magnetic polarization means that the magnetization ability is strong, the excitation current of the iron core is reduced, and the specific total loss and iron loss are reduced.

Oriented silicon steel, also known as cold-rolled transformer steel, is an important ferrosilicon alloy used in transformer (core) manufacturing industry. The most widely used oriented silicon steel is supplied in the form of a coil, and its surface is coated with an insulating layer to generate tensile stress in the base steel strip, thus further reducing the iron loss value.

The low silicon wafer contains less than 2.8 silicon and has a certain mechanical strength. It is mainly used to manufacture motors, commonly known as motor silicon steel sheets.
