With the rapid development of China's economy and equipment manufacturing industry, China's steel output has also risen sharply, and it has become a global steel-producing country. In order to increase steel output, major domestic steel mills purchase and install a large number of steel production lines. However, domestic high-end, advanced rolling mills and other steel equipment are mainly imported products, such as equipment and equipment of multinational enterprises such as Sweden, the United Kingdom, Germany, the United States, and Japan. The key components. The main imported brand of high-speed wire rod finishing mill cone and roll box bearings is Mogen t bearings, and the main imported brands of supporting bearings for wire and bar guides such as SKF and NSK. Precision rolling mills use imported precision bearing bearings including SKF, SCHAEFFLER, NSK, JTEKT, and TIMKEN in the United States. In order to meet the needs of steel companies, domestic bearing companies have developed products for typical high-end precision rolling mill bearings, but the results are not ideal The main technical problems are as follows: ① Early labor of inner and outer raceways: ② Broken rolling body: ③ Broken outer ring, etc. The bearing life and technical performance of domestic precision rolling mill bearings are far from meeting user needs. Therefore, the reliability and precision of precision rolling mill bearings are improved. Life is a problem that needs to be solved urgently in the domestic rolling mill bearing manufacturing industry. According to the actual use conditions, technical development of steel rolling mill bearings and other technologies will use product design and manufacturing technology with strong service conditions and service technology; its product development and product development And technology development and management will therefore have distinctive characteristics. According to the important progress of precision backing bearing precision manufacturing technology and a large number of installed service experimental research (UMG), the main crystal production suppliers, namely European SKF and SCHAEFFLER, have mastered the core technology; through the product installation experiment, we can see that JTEKT and NSK are The continuous improvement of key technologies has also made important progress; Timken products in the United States have gradually kept up with the level of research and development to avoid remaining raceways.
