In order to implement the spirit of General Secretary Xi Jinping's speech on "developing new productive forces according to local conditions" and "strengthening innovation and cultivating emerging industries" at the second session of the 14th National people's Congress, it is undertaken by Hebei Longfengshan Chenxin New Materials Technology Co., Ltd., in cooperation with Shanghai University, Economic Research Center and China Metallurgical newspaper. The innovative development of the first domestic fire preparation of 4N grade high purity iron industrialization project is in full swing to speed up the construction. It is understood that at present, the construction of the main factory building has been completed, and most of the major production equipment has been basically installed, and it is about to enter the stage of stand-alone commissioning, and it is expected that the full line will be completed next year. 4N grade high purity iron is a key basic material in the new material industry, which has excellent physical and chemical properties and special functions, such as ductility, corrosion resistance, soft magnetism, electrical conductivity, thermal conductivity and so on. it is widely used in aviation, aerospace, shipbuilding, nuclear power, medical equipment, electronic and electrical appliances, new energy vehicles, marine engineering and other high-end equipment manufacturing, national defense science and technology industry and high-tech fields. 4N-grade high-purity iron has been successively listed in the catalogue of Industrial basic Innovation and Development (2021 Edition) (in the field of new materials) (guided by the Chinese Academy of Engineering and the National Manufacturing Power Construction Strategy Advisory Committee, compiled by the National Industrial basic expert Committee), the Ministry of Industry and Information Technology "the first batch of key new materials application demonstration catalogue (2024 edition)" and the National Development and Reform Commission "Industrial structure adjustment guidance catalogue (2024)" encouragement category. The production and application of new materials of super pure iron can reflect a country's scientific and technological innovation ability and industrialization level. For many years, the high-grade pure iron market has been monopolized by Japan and developed countries in Europe and America, and it has become one of the key strategic issues in the field of key basic materials in China. To this end, in September 2022, 15 academicians headed by Academician Gan Yong jointly put forward the "proposal on speeding up the Development of China's Pure Iron Industry" to the relevant state ministries and commissions, aiming at further accelerating the development of China's high-purity metal materials and realizing the self-reliance and high-quality development of China's new materials industry. * * under the leadership of a team of experts headed by Professor Dong Han of Shanghai University, the project takes the unique liquid high purity pig iron of Longfengshan as the base material, carries out the research and development of 4N grade high purity iron and 5N-6N grade ultra-pure iron, focuses on basic research and industrial technology development, and seizes the commanding height of the industrial production of high purity iron-based new materials. The company's experimental project "Research and Development of 4N Super Pure Iron" won the only gold medal in technological innovation in the field of new materials in the Fifth China Advanced Technology Transformation and Application Competition in 2023. * * 4N grade high purity iron industrialization project is the first phase of the iron-based new material quality improvement project, mainly the construction of purification system, vacuum degassing system, pouring and solidification system, centralized control center and supporting environmental protection and public auxiliary facilities. Since the start of construction, by the end of March 2024, the construction of the purification workshop, vacuum degassing workshop, pouring and solidification workshop and other main workshops with a total construction area of 95000 square meters and the supporting 110KV substation has been completed; part of the main production equipment has been basically installed; some production facilities and supporting water treatment systems are under construction, and some of the main equipment has entered the stage of stand-alone commissioning in May. After May, we still need to complete the remaining project of more than 400 million yuan, and by the fourth quarter of this year, we can have the conditions for commissioning and enter the stage of hot installation and commissioning. The whole industrialization project will be completed in 2025 to produce a new high purity iron material with 99.99% iron content. During the construction of the project, the high-end market application docking of 4N grade high-purity iron will be carried out simultaneously, and a strategic framework will be formed with Yonggang Group at the end of the year to expand the personalized market application of new high-purity iron materials.
