Recently, No. 4 twenty-high roll mill of Beijing Shougang Co., Ltd. has successfully completed producing the high grade silicon steel with excellent rolled plate and clean surface, indicating that the No. 4 twenty-high roll mill has a successful thermal test and the set of silicon steel is completely finished and put into operation.

With the implementation of national efficient and green energy development strategy and the continuous upgrade of household appliance industry and new energy vehicle brands, the market demand for efficient high grade non-oriented silicon steel will be high. By adhering to the "market-oriented, customer-focused, with economic benefit as the core" development principle, focusing on the industrial growing trend, customer need and researching and judging in advance, Shougang silicon steel applied for the construction of supporting comprehensive silicon steel project two years ago and has obtained the approval in decision-making. After that, the Company vigorously participated in different preparatory work including technical negotiation, scheme design and tenders and bids to ensure the compliance of project process and preciseness of materials; meanwhile, it overcame the difficulties such as deep foundation pit construction beside the production units in the existing factory, innovated the construction methods to ensure the construction progression and safe control and efficiently coordinated both engineering construction with production organization to achieve balanced development. Different participating units vigorously collaborated to jointly resolve the difficulties and all the employees carried on the spirit of entrepreneurship and working standards of "never leaving a problem and strictly following the standards" and concentrated on the project construction without distraction to ensure the high-speed project construction and high-quality project operation.

Supporting comprehensive silicon steel project is a significant technology upgrade project open to advanced industries or technologies such as downstream efficient electrical machines, household appliances and new-energy vehicles. After the completion of the project, the annual capacity of Shougang efficient high grade non-oriented silicon steel will be largely increased and its structure and quality will meet the further market demand for high-end products.
