Chinese steel giant Baowu electrical steel is used in unit 6 of China’s largest nuclear power plant Liaoning Hongyanhe Nuclear Power Plant, which successfully completed a 168 hour trial operation and was ready for commercial operation. As the first brand of silicon steel in the world, Baosteel Silicon Steel has made another breakthrough in the localization of key materials in the field of nuclear power, becoming the only domestic silicon steel supplier for the second phase of this project.The 4 units of the first phase of Hongyanhe Nuclear Power Plant use CPR1000 nuclear power technology with independent intellectual property rights of China General Nuclear Power. Baobian Electric contracted the Hongyanhe Nuclear Power Plant Unit 5 and Unit 6 to supply related transformers using high magnetic induction oriented silicon steel products from Baosteel’s Qingshan Base.In recent years, the manufacturing technology of high magnetic induction oriented silicon steel in Qingshan Base has made great progress. The new generation of low temperature HiB steel process has been successfully developed, and the electromagnetic properties and surface state have been significantly improved, leading the industry. It has been used in Fuxing high-speed railway traction transformers, large offshore wind power plants, the world's first nuclear power plant in China's Hualong No 1 Fuqing Nuclear Power Plant Unit 5, and China Guangdong Nuclear Power's Zhejiang San'ao million-level nuclear power plant.In addition to this project, Baosteel and Baobian Electric are also working together on CGNPC Fangchenggang Power Substation and CNNC Fuqing Main Substation Project to jointly promote the localization of key raw materials for nuclear power equipment. After years of hard work, Baosteel is now accelerating the localization process of grain-oriented silicon steel for various transformers in the field of nuclear power, striving to become the vanguard of the comprehensive localization of key raw materials in all voltage levels and all application fields of transformers.
