CTOnews.com, September 1, according to CCTV news, the high-grade non-oriented electrical steel production line independently developed and built by China has been put into production in Qian'an, Hebei Province on August 31, and the new material will greatly improve the motor power density and motor efficiency of new energy vehicles.

CTOnews.com learned that non-oriented electrical steel, as its name implies, has isotropic magnetism (also known as isotropic electrical steel), which is widely used in the manufacture of all kinds of motor and electronic transformer cores. In China, the use of non-oriented electrical steel accounts for about 90% of the total use of electrical steel.

In 1882-1900, R.A.Hadfield, an Englishman, found that adding a certain amount of silicon to steel can greatly reduce the iron loss, which is the origin of non-oriented electrical steel. At present, the industry believes that electrical steel is the core material to drive modern industry.

Over the past 40 years of reform and opening up, by learning foreign advanced technology, digesting and mastering foreign advanced patent technology, China's electrical steel industry has been developing and growing. Over the past 40 years, we have developed a series of products with independent intellectual property rights, improved the production process and continuously improved the equipment. through long-term efforts, China's electrical steel production technology has developed rapidly, and the output of electrical steel ranks first in the world.

According to reports, the two electrical steel products for new energy vehicles put into production in the above production line can be used as the core functional materials of the drive motor of new energy vehicles, which can meet the needs of higher efficiency of the drive motor, and the efficiency of the motor can be improved by more than 0.8%.

If it is calculated that each electric car runs 50 kilometers per day, 20 million cars can save 5 million kilowatt-hours of electricity every day. Officials say that after this production line is put into production, we will open up a new process path to lead the new energy automobile materials industry.
