From a long-term perspective, smelting equipment needs to be transformed into short process method, green hydrogen smelting, carbon capture and other technologies.
Promoting the use of EAF smelting can significantly reduce carbon emissions in the steel industry, so the existing blast-converter production line can be gradually converted to EAF production line. As of 2021, China's electric arc furnace steelmaking capacity is 18,600 tons, with a CAGR of +13.4% in the past five years, but the proportion is far lower than the world's major regions and average levels.
In December 2020, the Ministry of Industry and Information Technology issued the "Guiding Opinions on Promoting the high-quality Development of the Steel Industry (Draft for comments)", which requires China to increase the proportion of electric furnace steel production to more than 15% by 2025, and strive to reach 20%, and the future of China's electric furnace smelting method of steel making has huge room for improvement.
2.1.2 Company side: The whole industrial chain of metallurgy has significant advantages, and hydrogen metallurgy + intelligent transformation leads the future
Metallurgical technology is comprehensive, and the whole industrial chain has outstanding advantages. As the world's largest metallurgical construction contractor, the company has undertaken the planning, investigation, design and construction of the main production facilities of almost all large and medium-sized iron and steel enterprises in China, and is in an absolute leading position in the eight aspects of steel production process: its subsidiaries China Enfei and China Huaye are good at mining and mineral processing; MCC Changtian, MCC North, MCC coke resistance deep ploughing sintering and coking technology; Ccid is good at blast furnace ironmaking; MCC Tiangong, MCC Jingcheng and MCC South have advantages in the field of steelmaking and hot rolling, and the cold rolling technology is mainly promoted by MCC South. At present, the company occupies 90% of the domestic and 60% of the global metallurgical market, fully reflecting the hard strength of China's metallurgical construction with the advantages of the whole industrial chain.
Actively layout of hydrogen metallurgy process to speed up the short process iteration process.
In terms of process technology, the company has formed a number of advanced technical products by accelerating the research and development of core technologies and processes and centering on the goal of green intelligence.
Ccid, a subsidiary of MCC, put forward the main line of "hydrogen energy preparation-hydrogen smelting - CCUS", and realized the technical route of green low hydrogen metallurgy through three technical paths of hydrogen rich reduction low carbon blast furnace, hydrogen base shaft furnace direct reduction, and hydrogen base melting reduction based on high efficiency pre-reduction. Its subsidiary, MCC Jingcheng, is committed to the research of low-carbon metallurgical technology, has completed the research of gas refining technology based on dry process, and has mastered the technology of 𝐶𝑂2 extraction and deep processing.
In December 2020, the "MCC Jingcheng - Tang Steel International" consortium led by MCC Jingcheng won the bid for the hydrogen energy development and utilization project demonstration project of Hesteel, which officially opened the substantial pace of hydrogen metallurgy development in China, and is expected to promote the transformation of the steel industry from traditional "carbon metallurgy" to a new type of "hydrogen metallurgy".
Power production line transformation and intelligent operation and maintenance to create the second growth curve of metallurgical engineering.
In terms of engineering and technical reform, the subsidiary MCC Baosteel has outstanding advantages, with modern metallurgical production and operation service capabilities, and has experience in providing equipment maintenance, production and operation, technology upgrading and transformation services for large metallurgical enterprises at home and abroad. Metallurgical engineering and technical reform covers iron and steel enterprises, steel series, rolling series, public auxiliary facilities and so on.
