Recently, the "Key Technology Research and Development and Promotion and Application of High-quality Bearing Steel Clean Production Platform" led by Shanxi Iron and Steel Co., Ltd. won the second prize of the 2022 Shandong Science and Technology Progress Award, marking Shanxi Iron and Steel's clean control technology for bearing steel. research has reached a new level.
The "cleaner" the bearing steel means the more "durable". In order to produce cleaner bearing steel, since 2018, relying on key research and development projects in Shandong Province, Shandong Iron and Steel Research Institute has closely focused on the goal of "construction of a clean production platform for bearing steel" and gathered forces from all parties involved in "production, marketing, research and application". Coordinate superior resources, gather strength to overcome difficulties, form key technologies such as clean production, greatly improve the quality of bearing steel products, and realize the localization substitution of some bearing steel application fields in the province.
"At present, there is still a systematic gap between my country's bearing products and the international advanced level, especially high-end bearings are still the short board of my country's high-end manufacturing industry." Dr. Xu Rongchang, a first-level researcher at the Emerging Industry Technology Research Institute of Shanshan Iron and Steel Research Institute, said, "High The R&D, promotion and application of key technologies for the clean production platform of high-quality bearing steel are of great significance to improving the quality of Shangang's bearing steel products, promoting the development of high-end equipment manufacturing, and enhancing international competitiveness.
Xu Rongchang introduced that gas elements such as oxygen and nitrogen in the form of bubbles or inclusions in molten steel are the root cause of quality defects. The lower the oxygen content in the bearing steel, the less inclusions, the higher the purity, the more uniform the structure, the stronger the bearing steel and the longer the fatigue life. Therefore, solving the "cleanliness" problem has become the primary link in improving the quality of bearing steel.
"For bearing steel, there is no key point of research, because it is everywhere." Xu Rongchang said that from raw materials to smelting to pouring, the factors affecting the "cleanliness" of bearing steel are complex, there are many technological breakthroughs, and it is difficult to complete. The project team made full use of the "one institute, multiple centers" research and development platform and the "five-in-one" operating mechanism, starting from the whole production process, focusing on raw materials, oxygen content, refining slag system, inclusions, protection pouring, organizational regulation, etc., successively More than 50 technical details were sorted out.
The project team systematically optimized the low-oxygen and low-titanium smelting process of bearing steel, and successively researched and developed high-quality bearing steel inclusion detection technology, inclusion rare earth modification technology, pulse external field suppression A series of key process technologies for the purification of high-quality bearing steel, such as nozzle plugging technology and microstructure control technology, continue to improve the level of bearing steel manufacturing technology. From 2018 to 2021, the annual average oxygen content of bearing steel will drop from 11.3PPM to 6.0PPM, and the purity, stability and fatigue performance of bearing steel will be greatly improved. According to the test by authoritative organizations, the contact fatigue life L10 of Shangang bearing steel exceeds 107 times, reaching 2.7×107 times, entering the domestic advanced ranks. At present, the key technologies of the project have applied for 15 invention patents, applied for and authorized 8 utility model patents, and formulated 2 related group standards.
With "diamonds" in hand, it is easy to do "porcelain work". In order to realize the "double improvement" of the bearing steel quality and quantity of Shanxi Iron and Steel Co., Ltd., the project team, in conjunction with the relevant personnel of the marketing head office and the special steel business department, visited domestic bearing manufacturing bases, actively explored the middle and high-end bearing steel market, and successfully applied the products to the high-end metallurgical industry. Equipment and other fields, and successfully realized localization substitution. At present, the annual production and sales of bearing steel of Shanxi Iron and Steel Co., Ltd. have increased by 3 times compared with the same period of last year.
"Winning the second prize of the Shandong Provincial Science and Technology Progress Award is a great encouragement to our R&D personnel. In the next step, we will conduct in-depth research on the homogenization control technology of bearing steel, improve the uniformity of the carbide structure of bearing steel, and develop bearing rolling elements. Bearing steel research and development and other "revealing the list" projects have further enriched the types and uses of bearing steel. Use our steel to produce more bearings." Liu Chengbao, director of the Emerging Industry Technology Research Institute of Shanshan Iron and Steel Research Institute, said firmly.
"Actively build a 'material supply-manufacturing-testing and evaluation' full-chain technology innovation service model to realize the internal circulation of bearing steel production-bearing manufacturing-high-end bearing localization in upstream and downstream enterprises in the province." With this "domestic substitution" With the feeling of "culturalization", the team of the Emerging Industry Technology Research Institute of Shandong Iron and Steel Research Institute has embarked on a new journey.
