R & D Center

1. Technical advantages
Liaoning Province Yiliansheng New Materials Co., Ltd. is a professional manufacturer of high-speed steel roll research and development and production in China. It has been awarded the "casting high-speed steel roll production base" and the "specialized and refined" advantageous enterprise of China foundry by the China Foundry Association. It is a high-tech enterprise of the municipal high-speed steel roll engineering technology research center, and its technical force has the long-term and comprehensive technical support of the high-speed steel roll research and development expert group of China Iron and Steel Research Technology Group Co., Ltd.
The high-speed steel roll R&D team headed by senior engineer Gong Kailing is the first high-speed steel roll developer and producer in China, and the inventor of my country's first high-speed steel roll patent. It has been engaged in roll research and development and production for more than 30 years. Since then, we have accumulated rich experience, especially the unique technology in the research and development, manufacture and use of high-speed steel rolls, and obtained 9 national invention patents, of which 7 belong to the manufacturing technology of high-speed steel rolls. In 2018, he was responsible for drafting and formulating my country's first group standard of "Casting High Speed ​​Steel Rolls" (T/CFA02010116.1-2019), and organized and presided over the first, second and third national high-speed steel rolls for bar and wire rod mills. Use technical workshops. He is also one of the main drafters of my country's current national standards for rolls GB/T1504-2008 "cast iron rolls" and GB/T25825-2010 "hot-rolled steel strip rolls". He has published more than 40 articles and won 8 provincial and ministerial level scientific and technological progress two above prizes.
2. Serialized development and production of high-speed steel rolls
The high-speed steel rolls produced by Yiliansheng Company firstly manufacture high-speed steel rolls in series according to the characteristics of the rolling material and the number of rolling mills and rolling characteristics. High-toughness high-speed steel rolls, high-speed steel rolls used in intermediate rolling stands, heat-resistant high-speed steel rolls used in rough rolling stands, and high-alloy high-speed steel rolls used in controlled cooling and controlled rolling production lines. Research and develop a new generation of high-strength, heat-resistant, high-wear-resistant high-speed steel rolls used in the endless rolling production line of continuous bar rolling mills; the second is to optimize the composition of high-speed steel rolls to avoid the problem of component segregation in centrifugal production, while improving The high-speed steel roll heat treatment process is adopted to enhance the hardness uniformity of the roll. For the high-speed steel rolls produced by the company, through the optimization of composition and the improvement of heat treatment process, the surface hardness uniformity of the roll body is not more than 2HSD, and the cutting performance of the roll is significantly improved; the hardness drop of the working layer is not more than 1HSD, and the stability of the use of the roll is greatly increased. , the comprehensive service life of the roll can be increased by about 20% compared with the previous similar products, but the sales price of the roll does not increase, which is deeply loved by the majority of users.
