Silicon Steel Product Details
1. Product Introduction
Silicon steel, also known as electrical steel, silicon steel sheet, and electromagnetic steel, is an iron-silicon alloy soft magnetic material with silicon content ranging from 0.5% to 4.5%. Through strict control of alloy composition, rolling process and heat treatment process, it features extremely low core loss, high magnetic permeability, high magnetic induction strength, excellent blanking performance and stable magnetic properties. It is an indispensable core functional material in the fields of power transmission, motor manufacturing, new energy equipment, home appliances and electronics. The product is widely used in manufacturing iron cores for various transformers, electric motors, generators and reactors, which directly determines the energy efficiency level, operation stability and service life of equipment.
2. Product Classification
2.1 By Grain Orientation Structure
Grain-Oriented Silicon Steel (CRGO)Grains are highly ordered along the rolling direction with obvious anisotropy, low core loss and high magnetic induction strength. It is mainly used in distribution transformers, power transformers, instrument transformers, reactors, large power supply equipment and other products with high energy efficiency requirements.
Non-Grain Oriented Silicon Steel (CRNGO)Grains are uniformly distributed with isotropic magnetic properties and excellent shearing performance. It is mainly used in various motors, generators, new energy vehicle drive motors, wind power motors, household appliance motors, small power equipment and other rotating machinery.
2.2 By Production Process
Cold-Rolled Silicon SteelIt has high thickness accuracy, flat shape, smooth surface, uniform insulating coating and stable electromagnetic properties, making it the mainstream high-end product in the current market.
Hot-Rolled Silicon SteelRelatively low cost and moderate processing performance, mostly used in low-end applications such as ordinary low-voltage electrical appliances and small simple iron cores.
2.3 By Thickness Specification
Conventional thicknesses: 0.10mm, 0.15mm, 0.20mm, 0.23mm, 0.27mm, 0.30mm, 0.35mm, 0.50mm. Special ultra-thin or thickened specifications can be customized according to customer requirements.
3. Common Grades
Non-Grain Oriented Silicon Steel: 50W470, 50W600, 50W800, 35W300, 35W440, 50WW1300, etc.
Grain-Oriented Silicon Steel: 23Q85, 23Q110, 27Q100, 27Q120, 30Q120, etc.
High Magnetic Permeability HiB Grain-Oriented Silicon Steel: Suitable for large ultra-high voltage transformers and high-end power equipment, with lower core loss and higher magnetic induction.
