Superhard materials are known as “industrial teethâ€. Henan is the leader in the domestic superhard materials industry, accounting for more than 80% of the national market. On March 22, the Henan Provincial Superhard Materials Discipline and Industry Development Report (hereinafter referred to as the “Reportâ€) approved by the Provincial Association for Science and Technology was released at the 4th China Superhard Materials Industry Development Forum on Henan Superhard Materials Industry. How to further develop its advantages and develop a direction for the “superhard†industry in China's manufacturing industry. Henan's superhard materials industry forms an overall competitive advantage. Superhard materials refer to diamond and cubic boron nitride and related composite materials. The "Report" pointed out that high-efficiency precision superhard material tools are one of the high-end tools irreplaceable for the high-end development of modern industry, and have more than 100 times leverage for the development of the national economy. It can be said that although the super-hard materials industry is small, it is a strong industry in the manufacturing industry. "Since the birth of China's first synthetic diamond in Henan in 1963, our province has become a radiation source for domestic superhard materials research and development centers and technical personnel." Gao Wensheng, vice chairman and secretary general of Henan Mechanical Engineering Society, told reporters. After more than 50 years of development, our province has realized the transformation of research and development and industrialization bases for super-hard materials and products, laying a solid foundation for China to become a global superhard material production country. According to the "Report" data, Henan Province is the most concentrated area of ​​China's super-hard materials and products enterprises. It has nearly 300 super-hard materials and products manufacturing enterprises. In 2016, the province's super-hard materials and products industry realized sales income of 30 billion yuan. The industrial added value exceeded 10 billion yuan. In 2016, the top three diamond production companies in Henan Province, Zhongnan Diamond, Yellow River Cyclone, Zhengzhou Huajing Company's total output accounted for more than 80% of the national total; while the production of cubic boron nitride enterprises are almost all concentrated in Henan Province, production It accounts for more than 95% of the national total. The continuous breakthrough of key technologies has brought bright prospects. The “Report†shows that during the “Twelfth Five-Year Plan†period, various sub-areas of Henan superhard materials industry have achieved a large number of scientific research and development and industrialization achievements with international cutting-edge technology level, and continuously expanded the industry. Expansion capacity. For example, the successful development of large-scale nano-polycrystalline diamond will lead to revolutionary progress in the field of diamond tools, solving the difficult problem of high-hard material processing in the fields of aerospace, defense and military industries; the successful development of gem-quality diamonds and industrial production has broken Foreign technology monopoly has made China one of the world's largest producers and sellers of synthetic diamonds; the strategic emerging industries such as modern communications have used chip-shaped diamond single-crystal tool materials to break through key technologies and achieve industrialization, breaking the developed countries for more than 20 years. The market monopoly has been sold to domestic and foreign markets in large quantities... It is worth mentioning that, due to the breakthrough of many key technologies, the technology of sawing and drilling tools of some enterprises in Henan Province has been promoted to the world's leading level. "The development of China's new diamond wire cutting tool industry is in the ascendant. Since the first half of 2017, the diamond micropowder industry has been in short supply." Professor Wang Qinsheng, chief expert of the National Superhard Materials Industry Base, explained: "Currently, the global photovoltaic industry, IT processing industry, The wire cutting tool manufacturing industry is focusing on China. For the processing of crystalline silicon wafers, LED lighting equipment, electronic products, high-end screens and protective screens, military equipment displays, etc., high-efficiency, precise and low-cost new diamond wire cutting tools are needed. huge market demand. "With intelligent manufacturing sharpen the" industrial teeth "in the implementation of" Made in China 2025 "process, intelligent manufacturing is the main direction. The application of superhard materials is broad, and it is the perfect carrier for green, efficient and intelligent processing. How to use intelligent manufacturing to sharpen the "industrial teeth" of superhard materials to ensure its healthy and orderly development? According to the "Report", for the super-hard materials industry, the level of automation in material production and diamond saw blade and wire saw production is relatively high. First, we should encourage and support these areas to vigorously promote intelligent design and manufacturing; the level of automation in other product fields is relatively low. The automation of the connection to the line should be the main goal during the “Thirteenth Five-Year Plan†period, and strive to achieve partial design and manufacturing intelligence by 2025. Although the super-hard materials and products industry in Henan Province has formed an obvious competitive advantage in the industrial chain, the problem of “big but not strong†has become more and more prominent, mainly reflected in the unreasonable product structure, mainly in the middle and low-end products, and high-end. Lack of products, production technology, equipment technology can not meet the development requirements of high-end products and green production, the industry chain urgently needs to upgrade to high-end transformation. In this regard, the "Report" suggests that Henan Province should speed up the transformation and development of the new materials industry, adhere to the "high-end, composite, productization", and soon build a domestic leading, internationally renowned superhard material production base; the government further increase the super Support for the construction of innovative systems in the hard materials industry; the establishment of the first spot trading center for superhard materials in Henan Province, and the establishment of “Henan price†and “China price†for super-hard materials. “Regular and irregular release of disciplines and related industry development reports has become an important measure for the provincial associations and associations to play the role of think tanks and serve regional economic and social development, and plays an important role in building regional technological innovation systems.†Party Secretary Cao Kui told reporters that in recent years, the Provincial Association for Science and Technology has accelerated the promotion of regional technological progress and economic development by organizing specialized academic forums. “Last year, the China Superhard Materials Industry Development Seminar was held in Qicheng County, Shangqiu, which led Huajing Group to invest in the construction of a synthetic diamond production base in Yucheng with a total investment of about RMB 5 billion.â€
