The Steel Research Institute officially entered the field of superhard materials in 1981. Since the development of the diamond geological drill project, after more than 30 years of development, today's Beijing Antai Steel Research Superhard Materials Co., Ltd. (referred to as Antai Superhard) has It has developed into a key enterprise in the industry with large-scale industrial scale, advanced technology, complete product variety and specifications, and enjoys the reputation of international brands and steadily moving forward in anti-dumping response.
In order to commemorate the 50th anniversary of the birth of synthetic diamonds, in the industry evaluation activities organized in September, Antai Super Hard won the “Innovative Enterprise†crown, the former general manager Chen Zhe, through the application materials, qualification examination, judging voting and website publicity procedures. He was named "Innovative Entrepreneur", and Liu Yibo and Luo Xiyu were awarded "Outstanding Contribution Experts".
First, pay close attention to opportunities, overcome technology, and after more than 30 years of tempering, realize the major seven engineering technologies in the industry first or early in China.
In 1981, the research institutes converted, the "weaning" impact of the original four-chamber (Powder Metallurgy Research Laboratory) researchers who made significant contributions to nuclear fuels, they took the initiative to ask for the project and produced the "Diamond Geological Drill" project (team leader) Luo Xiyu), after four years, successfully developed a variety of geological core drills, and transferred to small batch production. In the mid-1980s, with the rise of China's stone processing industry and the development of spurt, the original four-chamber organized the trial production and mass production of large diamond saw blades. Afterwards, with the vigorous development of the building materials industry, the development of diamond small saw blades was organized. (Peng Xianqi and several other original four-room old people), in 1989, the first in China to develop successfully "integral forming free-sintering small saw blade (referred to as Cold-pressed-sintered sheet), the saw blade was exhibited in the Canton Fair in 1990, which shocked the entire industry and won many foreign orders. In 1991, the company realized the industrial production of cold-pressed sheet. In 1995, it became the first enterprise in China with sales exceeding 100 million yuan, and launched the Shijiazhuang and Danyin regions with the technology as the core. The film entered the international market and made an indelible achievement. In 1994, the company took the lead in introducing laser welding machines in China. In China, it opened the door for exploring laser welding saw blades and drill bits. On the basis of conquering laser welding technology and laser welding special powder, more than ten laser welding machines were introduced one after another. The largest laser welding tool production, export and R&D base in China. In the late 1990s, the company took the lead in developing the “integrated pressure-sintered saw bladeâ€, which satisfied the requirements of advanced tools in the international market. In 2001, it was restructured and listed as a holding subsidiary of “Antai Technologyâ€.
Antai Superhard has achieved four major engineering technologies in the early stage in China: First, the carcass pre-alloyed powder for diamond tools, which was jointly developed and successfully applied with Antai Powder, and affects the national industry. The laser powder special powder and ingredient design is still The first in China; the second is the use of powder catalyst and graphite powder to synthesize diamond, the yield and quality are greatly improved at the same time and the production cost is significantly reduced, replacing the domestic leader of early sheet-like synthesis technology, and mastering the preparation of gem-quality single crystal and polycrystal. The key technology; the third is to use brazing solder, consolidate diamond, greatly improve the efficiency of tool operation, the development and successful application of brazing saw blades and drill bits necessary for disaster relief; Fourth, change the random distribution of traditional diamond particles into an orderly arrangement, Development and application of directional diamond tools that increase operational efficiency and reduce costs.
Antai Super Hard is market-oriented and has taken over the technology. The development of seven major engineering technologies has grown and expanded. The current assets have exceeded 400 million yuan. In recent years, despite the economic downturn and anti-dumping from the United States, sales have been stable for many years. At more than 300 million yuan. At present, it produces 8 series and more than 3,000 kinds of products, and more than 80% are sold to the United States and the European Union.
Second, rational treatment, organization of the team, scientific response, after eight years of anti-dumping response to the United States to obtain satisfactory results
China's diamond tools have opened the door to the world's largest consumer market with high cost performance. From 2002 to 2004, the number and amount of export saw blades doubled. This has greatly stimulated the US local manufacturers. On May 3, 2005, they jointly filed an anti-dumping application with a punitive tariff of up to 298% to the CCPIT and the Ministry of Commerce. At this time, in the domestic fear of anti-dumping, the confusion of the corresponding complaints, and the unpredictability of the prospects, Chinese diamond companies face a difficult choice.
Antai Super Hard under the flag of most companies, resolutely decided to set up the responding working group headed by the former general manager Chen Zhe on May 15th. Until the end of 2013, the anti-dumping response has gone through 8 years. After experiencing the damage investigation stage of the US Trade Promotion Association, the US prosecution litigation and anti-litigation multiple rounds, the US Department of Commerce's original investigation, three annual review tax rate investigations, the WTO dispute settlement mechanism zero appeal and many other lines are intertwined. . The latest results: In 2013, the US Department of Commerce made a final ruling on the second review. Antai's super-hard anti-dumping margin was zero, and the remaining 22 companies had a weighted average tax rate of 8.1%. Antai Super Hard strives for such satisfactory results. It cannot be said that it is inseparable from the working group to face challenges, dare to take responsibility, be good at learning, and answer scientifically. According to incomplete statistics, the US Department of Commerce has issued more than 90 questionnaires to the country, involving more than 6,000 specific issues.
Third, expand stock production, adjust product structure, and march into the modern processing field of metal and precious materials
Antai Superhard is currently mainly engaged in the production and processing of hard and brittle non-metallic materials, such as cutting, drilling and grinding and polishing diamond tools for concrete, asphalt, stone and building materials. Such tools have large market capacity, other tools are irreplaceable, and new products and processes need to be dug up. It is still the main battlefield for enterprises to stably expand the production of such tools. At the same time, however, it is seen that a new market for superhard materials is emerging: first, PCD (diamond polycrystalline composite) and PcBN (cubic boron nitride polycrystalline composite), which are difficult to process metals, are becoming efficient after being cemented carbide tools. High-precision, high-life, green and environmentally friendly cutting tool materials: Second, the processing of precious materials, such as photovoltaic industry semiconductors, LED industry sapphire and other cutting, grinding and polishing tools. Antai Superhard has deployed this new front, developed new products, and blew the horn of superhard materials and products needed to enter the modern processing industry! (The call here is just a small investment and a slow process.)
The achievements belong to the past, and the new future is coming. The "super-hard" people will carry forward the super-hard character, concentrate on the road of innovation drive, and use the "super-hard" sharp teeth to overcome the barriers and create new glory. .
