, )Introduction to silicon steel
, ) .Silicon steel, also known as electrical steel, commonly known as silicon steel, is a kind of extremely low carbon content,) ferrosilicon
soft magnetic alloy, also the largest output The largest metal functional material, silicon steel is mainly used as the core of various motors, generators, compressors, motors and transformers. It is an indispensable raw material product in power, electronics, home appliances and even military industries.
, ). Silicon steel generally has a silicon content of .~.%. Adding silicon can increase the resistivity and maximum magnetic permeability of iron and reduce coercivity. Iron core loss (Iron loss),) Magnetic aging. Because the manufacturing technology is stricter than ordinary steel products, the production process is complex and the content is high, the process window is narrow, and production is difficult. Silicon steel was once called a handicraft among steel products, especially oriented silicon steel, which is more advanced than non-oriented silicon steel. It is known as the crown jewel of the modern steel industry. It is a symbol of the development level of a country's steel industry.
, ). With the development of the economy and the improvement of people's awareness of environmental protection, the requirements for silicon steel are getting higher and higher. Therefore, high-grade, low-iron-loss, high-magnetic, high-frequency, high-strength silicon steel has emerged. The thin specifications produced by Baosteel High-grade silicon steel has the advantages of low iron loss, high magnetic induction, low heat generation, and good punching properties. It can be widely used in new energy vehicle motors, drive motors, starter motors, miniaturized energy-saving household appliances and other products.

, ) .Silicon steel sheet performance indicators
, ) ., low iron loss. The most important indicator of quality, countries around the world use iron loss value to classify grades. The lower the iron loss, the higher the grade and the higher the quality.
, ) ., high magnetic induction intensity. Silicon steel sheets can obtain higher magnetic induction under the same magnetic field. The size and weight of the motor or transformer core made with it are relatively small, which can save silicon steel sheets, copper wires and insulating materials.
, ) ., high stacking coefficient. The surface of the silicon steel sheet is smooth, flat and uniform in thickness, and the stacking coefficient of the core is improved.
, ) ., good film processing properties. This is even more important for manufacturing small and micro motor cores.
, ) ., the surface has good adhesion and weldability to the insulating film, can prevent corrosion and improve the punching properties.
, ) ., The magnetic aging phenomenon is small
, ) . The silicon steel sheet must be annealed and pickled before delivery.
, ) Wuhan Iron and Steel Grain-oriented Silicon Steel Grade Naming Rules
, ). The thickness expressed in . means the ordinary oriented silicon steel coil of Wuhan Iron and Steel Co., Ltd., and the grade of silicon steel is expressed by times of the iron loss value under //.
, ). All countries use iron loss value to classify silicon steel grades. The smaller the number, the higher the grade. The iron loss of For electrical steel, the guaranteed value of iron loss / is not greater than ./.
, ) Baosteel Grain-oriented Silicon Steel Grade Naming Rules
, ) For example,) means that for ordinary oriented electrical steel with a nominal thickness of., the guaranteed iron loss value / is not greater than ./
