Silicon steel for UHV AC transformers has always been the technical field of foreign companies. In international trade, long supply cycles and high prices often occur. Compared with the status of foreign UHV transformer silicon steel products as "unusual goods", domestic high-performance oriented silicon steel urgently needs breakthroughs in technical difficulties such as magnetic properties, quality stability and yield rate, and the design of silicon steel sheets for UHV transformers is needed Selection criteria and innovation of application performance detection and evaluation methods under complex working conditions.

In order to break the foreign technology monopoly in the field of high-performance oriented silicon steel, the project team of China Electric Power Research Institute, led by Li Peng and Zhang Shuqi, adopted the industry-university-research-use model. Co., Ltd. has carried out joint research on the key technologies of comprehensive control of high-performance oriented silicon steel, developed stable nitriding control technology, laser scoring technology and intelligent magnetic domain control technology, and developed high-performance oriented silicon steel represented by B27R090 and other models The series of products have advanced key performance indicators such as magnetic performance stability, excitation power characteristics and unit iron loss.
