Overview of Grain-oriented Electrical Steel
Grain-oriented electrical steel, also known as cold-rolled grain-oriented silicon steel, refers to cold-rolled electrical steel that contains 2.9% to 3.5% Si and has a certain regularity and direction in the crystal structure of the steel plate. Grain-oriented electrical steel is an indispensable soft magnetic material in the electric power industry. It is mainly used in transformers, rectifiers, reactors, large motors and other industries. The Ministry of Commerce announced that it has ruled that imported oriented electrical steel products originating in Japan, South Korea and the European Union are dumped, harming China's domestic oriented electrical steel industry. It has decided to ban imported oriented electrical steel products originating from these countries and regions starting from July 23. Anti-dumping duties are levied on electrical steel products, with tax rates ranging from 37.3% to 46.3%, and the implementation period is five years.

Oriented Electrical Steel Uses
Grain-oriented electrical steel is an indispensable soft magnetic material in the power industry. Grain-oriented electrical steel is mainly used in various types of rectifiers, transformers, reactors and large motors, and is used to manufacture the cores of various transformers.

Grain-oriented electrical steel: ore---iron-making---steel-making---hot rolling---pickling--cold rolling---annealing---cold rolled silicon steel (grain oriented electrical steel)

The key to producing silicon steel with Gaussian texture from grain-oriented electrical steel is to use secondary recrystallization. In order to achieve secondary recrystallization, it is usually necessary to add normal grain growth inhibitors, such as MnS, to the alloy. The grain growth inhibitor must be dispersed in the alloy matrix in the form of doping. When secondary recrystallization occurs, it can effectively prevent the normal growth of the matrix crystal. At the same time, it requires final high-temperature annealing. can be easily removed to avoid deteriorating the magnetic properties of the product. In the secondary recrystallization, the orientation nuclei of secondary grain growth mainly rely on appropriate cold rolling process and recrystallization annealing. Since phase transformation destroys grain orientation, it is critical to maintain a single phase during heat treatment.
Cold-rolled electrical silicon steel sheets are divided into oriented silicon steel sheets, non-oriented silicon steel sheets and DW materials. Cold-rolled non-oriented silicon steel sheets for motors are commonly supplied in rolls with thicknesses of 0.35 and 0.50mm, and their silicon content is generally low; cold-rolled oriented silicon steel sheets for transformers are commonly supplied in thicknesses of 0.20, 0.30, 0.35, and 0.50mm. The silicon content is generally high.

Oriented Electrical Steel
The total output of electrical steel in the world is approximately 7 million tons. At present, especially in recent years, with the development of China's power and electrical appliance industries
With rapid development, China's demand for oriented electrical steel sheets has increased rapidly. In 2004, consumption accounted for almost half of the world's silicon steel sheet production. As a result, China's silicon steel production has entered a period of rapid development, but it is still unable to meet domestic demand. In 2004 The annual import of silicon steel sheets is 1.64 million tons.
Grain-oriented electrical steel has a history of hundreds of years. Grain-oriented electrical steel includes two types: electrical steel with Si <0.5% and silicon steel with Si content of 0.5~6.5%. It is mainly used as the core of various motors, transformers and ballasts. It is an important component of electric power, Not available in the electronics and military industries
Missing important soft magnetic alloys. Grain-oriented electrical steel is the largest used magnetic material and is also an important energy-saving metal functional material. The manufacturing process and equipment of oriented electrical steel, especially oriented silicon steel, are complex, the ingredients are strictly controlled, the manufacturing process is long, and there are many factors that affect performance. Therefore, the quality of oriented silicon steel products is often regarded as an important measure of a country's special steel manufacturing technology level. logo, and won the reputation of "art product" among special steels.
