The result of the "Taiwan crisis" has made the leaders of the Yellow River Company determined to find another way out. Qiao Jinling visited Professor Wang Guangzu and visited the superhard materials expert of Zhengzhou Abrasives Grinding Research Institute of the Ministry of Machinery Industry. Two retired directors, Qian Weigui and He Yiquan, went to Changsha to see the Metallurgical Minister Sha Mining and Metallurgy Research. Professor Chen Qiwu, dean of the hospital, went to Guilin to see Zhang Zhiyuan, a professor-level senior engineer of the Institute of Geology and Minerals of the Ministry of Geology and Mineral Resources. He also invited the chief engineer of the Zhongzhou Machinery Factory of the Ministry of Weapons Industry, professor-level senior engineer Han Zheng, and Zheng Henggong, professor of Zhengzhou Institute of Technology, to the Yellow River Group. The technical center in Zhengzhou consulted in person, and the insights of these super-hard materials senior experts made him establish the path of China's own development of diamond business - the belief of six-sided top press! So a seemingly impossible thing to do - with the power of a private enterprise, the personal identity of a peasant-born entrepreneur, to complete the routine should be from the central ministries, and at least a national-level industry association Coordinated, led and organized the diamond press large-scale project! Huanghe Company and Qiao Jinling invited the above-mentioned authoritative experts in the industry, as well as a professor of the Jinan Casting and Forging Research Institute of the Ministry of Machinery and the author of the book “Hyper-hard material production special equipment – ​​hinged six-face hydraulic press†Shen Xinde; I have invited more than 30 professors, scholars, and well-known experts in the design, manufacturing, electronics, diamond synthesis, and post-processing industries of the Ministry of Chemical Industry, Jilin University, Yanshan University, and the People's Liberation Army Information Engineering College. The scientific and technical personnel gathered in the technical center of Zhengzhou, in this building, everyone lives in Sri Lanka, works in Sri Lanka, studies, discusses, designs, and demonstrates. From August 28, 1996 to October 30, 1997, the team forgot to work, day in and day out. During the period, nine more expert meetings were held to study and solve various technical problems in the R&D process. The leaders of the Yellow River Company, especially Qiao Jinling, can say that they can't get out of the night, understand the situation, listen to opinions, think deeply, raise funds and make decisions continuously. People still remember that at the first expert team meeting from July 25 to 27, 1996, Qiao Jinling on behalf of the Yellow River Group Company firmly requested the development of a Φ33mm cavity, that is, a 6×1500 ton press! The experts were surprised! Such a large cavity, such a large tonnage, such a large press is something that experts can't think of beforehand. China's six-sided top press, developed from the first 6×600-ton press by the Jinan Casting and Forging Research Institute of the Ministry of Machinery in 1966, was not developed until 1987 by Taiyuan Heavy Machinery Institute and Changchun Test Machine Factory. ×800 tons of presses, this period has passed 21 years! From 6×800 tons to 6×1000 tons, it was only 4 years after Taiyuan Heavy Industry was successfully developed in 1991. Now that it is in 1996, it is still in this tonnage, and the Yellow River company has to jump from 6×1000 tons to 6×1500 tons! The firm determination of Huanghe Company and Qiao Jinling ignited the courage and confidence of the experts. Dean Chen Qiwu accepted the important task; Professor Zhang Zhiyuan provoked the design burden of the press; equipment manufacturing and machining were under the responsibility of Professor Han Zheng. Others such as processes, tests, etc. have been specifically divided. Qiao Jinling also proposed that the original operation mode of the press should be resolutely changed, that is, one person should be on duty, and according to the chart drawn by the craftsman, the different buttons connected by many relays can be hurriedly pressed. Qiao Jinling has seen intelligent operations in the United States and Japan, so it is required to be as intelligent as the United States and Japan! This task fell on the head of young expert Cao Qingzhong. Cao Qingzhong has experience in the design of automatic control of the direct-drawing single crystal silicon furnace. He also consulted a large amount of relevant materials, and after careful thinking, proposed the design. Qiao Jinling immediately invited professors and experts from the PLA Information Engineering Institute, Zhengzhou Institute of Technology, Jilin University, Yanjing University and Sanmao Institute to carry out demonstrations. After several modifications, the operation of the six-face press was finally realized. Nowadays, The Yellow River Cyclone Company has already been able to open more than a dozen large presses, greatly liberating productivity and greatly reducing costs. The decisions of the Yellow River Company and Qiao Jinling were implemented one by one. On August 27, 1996, the first 6×1500 ton prototype was produced on March 26, 1997. On October 28, 1997, the provincial technical appraisal was passed. By the end of 1998, 100 of these were officially The “UDS-6×1500 tons-I†press was named for the scale production of diamond. Afterwards, Dean Chen Qiwu said with emotion: "This kind of big project usually takes 5 years from project establishment to industrialization. It takes only one and a half years to go to the 'Yellow River'. This is a miracle! It is a private enterprise and a private enterprise. It’s a miracle to build a leader!" The development of UDS-6×1500 tons-I type press has obtained 11 patents in technology and won 4 scientific and technological achievements and scientific and technological progress awards at provincial and ministerial levels. Due to the technological advancement of the UDS-I press, the economic benefit is increased by 2/3. Since the unit cost is one-third lower than that of the same grade products produced by the US double-face press, it is highly competitive in the international market. The Yellow River Company and Qiao Jinling are a team that is constantly pursuing and never stops. They then developed the UDS-II and III presses, whose bore diameter is Φ650mm from Φ320mm; the cavity is Φ52mm from Φ33mm; the pressure is 6,000 tons. It has reached 22,000 tons; the single production has reached 140 carats from 40 carats; due to the improvement of its quality, the price per carat has reached 0.48 yuan from 0.12 yuan! Professor Deng Fuming from the Institute of Superhard Materials and Cutter of Beijing University of Mining and Technology said in his book "Chen Qiwu - Love Diamonds Half a Century" (see Henan People's Publishing House, "Recalling the Past and the Years"): "Yuhe Industrial Group Corporation UDS- The large-scale launching of the -1 large-scale high-pressure synthetic equipment and the Φ30mm cavity diamond synthesis process have been successfully promoted and applied, creating obvious economic benefits, which led to the company's successful listing in 1998, becoming the largest diamond company in Asia, especially the Yellow River. The group company uses this equipment to produce HHD30 products, which have been tested by Japan's ODK company, and its performance is close to that of foreign high-end products, setting a new milestone in the large-scale domestic six-face top equipment." The famous name of "Huanghe Cyclone" not only spurs China, but also has been famous in the world of superhard materials industry! On June 12, 2001, Wang Chunlin, the executive vice president of the company, visited the TYROLIT company in Austria. This is an internationally renowned superhard material company in Europe after the British element six. After the inspection, Wang Chunlin reported to Qiao Jinling: "They were warmly received by the company's CEO, Siegwart. What impressed them was that the company raised the Chinese flag to show respect and friendship to China and our company!" Qiao Jinling heard this, excitedly stood up from the seat, flashed in front of the scene of GE in the United States, and now the five-star red flag raised in Austria TYROLIT company, he can not help but tears... Yes! Huanghe Industrial Group and its subsidiary, the Yellow River whirlwind, have been recognized and respected by the world's peers! Also vying for the great motherland!
