Silicon steel

Silicon steel (also known as electrical steel) is a special type of steel whose main characteristic is excellent magnetic properties under alternating magnetic fields. Silicon steel has a wide range of applications and is mainly used to manufacture electromagnetic equipment such as motors, transformers, generators, ballasts, and drive systems for electric vehicles. Two important performance indicators of silicon steel: core loss and magnetic induction intensity.

Core loss (iron loss): Core loss is the energy loss caused by magnetization and reverse magnetization of silicon steel in an alternating magnetic field. This loss is an important consideration in motors and transformers made from silicon steel, as high iron losses can lead to wasted energy and heating of the equipment. Therefore, the silicon steel core should have lower iron loss to save electrical energy and improve the efficiency of the equipment.

Magnetic induction intensity (magnetic induction): Magnetic induction intensity is a measure of the degree of magnetization of silicon steel under the action of an external magnetic field. High magnetic induction intensity means that silicon steel has higher magnetic permeability and is more sensitive to the external magnetic field, thereby reducing the need for excitation current. This helps save electrical energy and improves the performance of electromagnetic equipment.

The core loss of silicon steel should be as low as possible, while the magnetic induction intensity should be as high as possible. This can achieve higher efficiency when manufacturing equipment such as motors and transformers, save electricity, reduce energy losses, and make equipment more lightweight and efficient. At the same time, silicon steel also needs to meet some other requirements, such as isotropy or anisotropy, excellent punching and shearing properties, flat surface and uniform thickness, good insulation properties and small magnetic aging, to ensure that it can be stable in practical applications. Works reliably.

Main components of silicon steel

Production Process

Fold pickling

The descaler and hydrochloric acid tank are used to remove oxides from the hot-rolled steel strip to prevent surface defects of the cold-rolled finished product.

Folding cold stamping

In order to ensure the thickness and material for different purposes, the reduction ratio is set at 40%-90%, and advanced control equipment such as automatic thickness control and automatic shape control are implemented.

Fold annealing

It is a process that softens the steel strip material that has been hardened in the cold stamping process. Through metal heating and rapid cooling, steel for deep processing and high-tensile steel are produced, and boxing (hood annealing) annealing and continuous annealing methods are used.

Folded insulating coating

When the silicon steel plate is processed into an iron core, in order to improve its processing performance and prevent eddy current loss equivalent to the thickness of the steel plate, continuous coating equipment is used to spray the insulating coating liquid on the upper and lower sides of the steel plate.

The main properties of silicon steel:

1. Low iron loss, which is the most important indicator of the quality of silicon steel sheets. Countries all classify grades according to the iron loss value. The lower the iron loss, the higher the grade.

2. The magnetic induction intensity (magnetic induction) is high under a strong magnetic field, which reduces the size and weight of the cores of motors and transformers, saving silicon steel sheets, copper wires, and insulating materials.

3. The surface is smooth, flat and uniform in thickness, which can improve the filling factor of the iron core.

4. Good punching properties are more important for manufacturing micro and small motors.

5. The surface insulating film has good adhesion and weldability, can prevent corrosion and improve punching properties.
