Characteristics And Applications Of Silicon Steel Sheets

1. Smooth and Flat Surface

Silicon steel sheets have a smooth, flat surface with uniform thickness. This characteristic helps improve the lamination factor of the core, which in turn optimizes the performance of motors and transformers.

2. Excellent Stamping Performance

Silicon steel sheets exhibit excellent stamping performance, which is particularly important in the manufacturing process of micro and small motors. Their outstanding stamping performance is crucial for the production efficiency and yield rate of small motors.

3. Advantages of Insulating Film

The insulating film coated on their surface not only has excellent adhesion and weldability but also effectively prevents corrosion and further enhances stamping performance. In short, the insulating film on silicon steel sheets improves stamping and welding performance while resisting corrosion.

4. Iron Loss and Grade

Iron loss is a key indicator for measuring the performance of silicon steel sheets. Countries around the world classify the grades of silicon steel sheets based on iron loss values: the lower the iron loss, the higher the grade. Iron loss value is an important standard for evaluating silicon steel sheet performance and directly affects the classification of their grades.

5. Magnetic Induction Intensity and Weight Saving

In a strong magnetic field environment, silicon steel sheets can exhibit high magnetic induction intensity. This property helps reduce the volume and weight of motor and transformer cores, thereby saving silicon steel sheets, copper wires, and insulating materials. Simply put, high magnetic induction intensity allows silicon steel sheets to reduce the size and weight of motors and transformers when used in strong magnetic fields.

6. No Magnetic Aging

Silicon steel sheets have almost no magnetic aging. This feature ensures the stability of their performance, meaning silicon steel sheets with almost no magnetic aging maintain stable performance during long-term use.

Power Equipment: Cold-rolled grain-oriented silicon steel (low loss) is used for transformers; cold-rolled non-oriented silicon steel (impact-resistant) is used for generators.

Motor Field: Medium-low grade non-oriented silicon steel is used for industrial motors (fans, machine tools); high-grade non-oriented silicon steel (high-temperature resistant) is used for new energy vehicle motors.

Consumer Electronics: Low-grade non-oriented silicon steel is used for home appliances (air conditioners, washing machines); ultra-thin non-oriented silicon steel (lightweight) is used for motors in mobile phones and computers.

Special Fields: Silicon steel suitable for high-frequency scenarios is used for high-frequency transformers in communication base stations and charging piles.
