Large-scale Transformer Oriented Silicon Steels

The Ministry of Industry and Information Technology recently held a large-scale localization promotion meeting for oriented silicon steel for transformers in Wuhan. It requires various power design and research departments, transformer manufacturers and property owners to implement adjustment and revitalization plans for the steel industry and equipment manufacturing industries, and use new steel Technology, new product research and development, improve large-scale transformer equipment, UHV power transmission and transformation equipment, such as autonomy.

The Ministry of Industry and Information Technology requires the downstream industries to actively support the steel industry in improving technology and improving product quality. It must establish a mutually beneficial strategic cooperation relationship with steel companies, vigorously promote the localization of major equipment materials, and strive to complete the trial production of domestic materials before the end of this year. Taiwan sets of 500 kV large transformers will lay a good foundation for the promotion and expansion of usage next year.

At the promotion meeting, some domestic large-scale transformer manufacturers reported on the use of Wuhan Iron and Steel (Group) Corporation silicon steel products to manufacture 220 kV transformers and test results, and introduced the trial application of oriented steel products of Wuhan Iron and Steel Company to replace imported materials on S13 energy-saving transformers. . The meeting held that the oriented silicon steel produced by Wuhan Iron and Steel Company has been used in the manufacture of transformers with a voltage level of 220 kilovolts. The qualified products have passed the test and basically reached the quality level of similar foreign products. This gradually frees China from relying on imports and being controlled by people. It has extremely important significance.

It is understood that the high magnetic induction oriented silicon steel in the cold rolled silicon steel sheet produced by Wuhan Iron and Steel Company has the advantages of high magnetic induction strength and low iron loss, and is the best silicon steel in the silicon steel family. It is widely used in large-scale transformer manufacturing, and its production process is very demanding. High, domestic companies can produce very few of the products.
