In the spring, the Party Central Committee embarked on economic recovery, and Rongke was recruited to the East China Textile Administration in Shanghai to participate in the construction of the Hangzhou Jingwei Textile Machinery Factory. In July of the same year, he helped the state-run Second Mechanical Factory to solve the problem of the foreign blockade of the manufacturing of the spacer, paving the way for the resumption of production of 2.6 million spindles in Shanghai. In October of the same year, the Korean War broke out, and the war burned to the Yalu River. At this time, Hangzhou Jingwei Textile Machinery Factory was ordered to move to Yuji, Shanxi Province. Rongke is responsible for the design and construction of the mechanized textile machinery foundry with an annual output of 10,000 tons. The beginning of the lack of confidence, had to foreign aid, but the conditions are too harsh, back to insist on self-reliance, the organization of the East China Ministry of Industry and the plant's technical staff, according to his blueprints for their own design, their own manufacturing, only 1 year and 3 months to complete China's first modern casting workshop construction tasks. For this, he was awarded the title of Model Industrial Worker in North China.
Ductile iron is a special cast iron, high tensile strength, high hardness, good toughness, high degree of heat resistance, is an important metal instead of cast steel, forged steel, is an important material for manufacturing textile machinery. And its cost is only cast steel 1/3, the use of ordinary cast iron equipment can be manufactured, easy to mass production. At that time, all over the country to manufacture ductile iron have to go through two treatments (i.e. two procedures), Rongke in July 26, 1952 creative use of silicon-iron copper-magnesium spheroidal agent, with a bell method of one time to deal with the iron to get good results, will be China's casting technology to move forward a step for the country to make a contribution. Firstly, once this advanced experience is generally promoted, it can save about 50% of copper to the country, and make the manufacturing cost of ductile iron reduce 25% compared with two treatments; secondly, it simplifies the operation procedure in manufacturing, saves labor, and lays the foundation for vigorously promoting the manufacturing of ductile iron. Thirdly, due to the high temperature of iron, good fluidity, greatly reducing the scrap rate, improve the quality. Such a ductile cast iron and then quenching method, can be made of Burrina 448 hardness wear-resistant needle cast iron, it is the automobile industry and the workhorse machine industry in the main material instead of steel. September 10, 1952, "Shanxi Daily" to "Rongke engineers and workers combined with the trial of ductile cast iron a successful treatment" as the title, made a detailed report. Detailed report. Then People's Daily, Workers' Daily and Ta Kung Pao reprinted it in full. For this reason, Rongke was awarded the title of Special Labor Model of Shanxi Province and the Silver Shield Memorial Prize engraved with the four big red words "Carrying Forward" issued by the Ministry of Textile and Machinery Industry. The Aeronautical Research Institute decided to try to produce a turbofan engine, with the Aeronautical Materials Research Institute as the chief metallurgist, responsible for the production of one machined part and three blanks, which were all under the charge of Rongke. The trial production task started rapidly. The trial production of aluminum alloy castings for the front and rear magazines and fuel attachments took only 3 months from process design, plant arrangement, production preparation to trial production and finalization. Through the trial production of the whole engine, the Institute of Aeronautical Materials created the conditions for the production of aviation forging and casting, and cultivated a group of metallurgical technology team with high level. In the same year, in order to realize China's self-designed high-altitude and high-speed J-8 aircraft assembled with dual turbojet 7A engine program, it is necessary to firstly develop the air-cooled hollow one-stage turbine blades. Rongke shouldered the heavy responsibility, under his guidance, brought together the relevant factories and institutes, especially Shenyang Institute of Metals, Shenyang Aero-engine Manufacturing Plant and Aviation Materials Research Institute of scientific research strength, and cooperated in the development of 9 small holes air-cooled casting of a first-class turbine blade. This is the key to the success or failure of the turbojet 7A engine, and also the problem of whether the dual-engine design of J8 aircraft can be realized. First of all, research and design of air-cooled hollow turbine blade test pieces, the establishment of the cooling effect tester and blade thermal shock tester, and one by one to overcome the selection of materials, precision casting mold design, core material core breakage failure, core technology, casting loosening, blade calibration and other technical keys, the turbine blade is finally a successful trial production for the success of the J8 aircraft test flight, made a significant contribution.
Air-cooled hollow casting first-class turbine blade development success, not only shook China's casting industry, in the international are also leading. At that time, the British Rolls-Royce aero-engine only used forged hollow blades, the casting of hollow blades can work under high loads, is not yet assured. Then it took 3 years before it was successful. The company's technical director Dr. Hooker visited China, saw the turbojet 7A engine casting hollow turbine blades, greatly surprised, he said to Rongke: "to see your casting hollow blades, is a big gain!" In this regard, Rongke did not say anything, just put a smile. At this moment, he remembered that 28 years ago, when he was an intern at Rolls-Royce, the British used cartoons in the newspaper to satirize the Chinese internship team, and he felt even more proud of being a Chinese. Rongke has always been optimistic about his illness. Although he got oral cancer and underwent a major operation, he never put a burden on his mind, but fought against the disease with strength and perseverance. Even in the most painful time after the operation, he never moaned. He loved martial arts, swimming, and sports, which was also a great asset for him to overcome the disease, and soon after he was discharged from the hospital in 1974, he learned Bagua Palm from his teacher. He was a keen learner, practiced hard and wrote many notes. There are more than three years, he always insisted on 4 to 5 times a week to get up early in the morning by public **** car rushed to Tiananmen Square to practice martial arts, regardless of spring, summer, autumn and winter, persistent. Afterwards, he always insisted on more than two hours of exercise every day, even if he went abroad on business trips, he never stopped. Everyone admired Rongke for this strong perseverance and tenacious spirit. He is also a director of the Beijing Wushu Association.
Kungfu is not a rewarding endeavor. Long-term perseverance in exercising has honed his strong body and agility, providing an important foundation for overcoming maladies and dedicating himself to aviation. Wushu also enable him to be fearless in the face of danger, criminals in front of the hero. late 70's a year in mid-summer, Rongke went to Hangzhou for a meeting, one evening to visit the West Lake, four lawless youths attempted to roadblock robberies. Just when they start, Rongke a show of force will be four thugs swept to the ground. They saw that the silver-haired old man was so skillful that they fled.
Rong Ke has been suffering from oral cancer for more than 20 years now, but has remained stable. This situation is also rare in the medical world. As a result, at a world medical conference in the 1990s, oncologist Wu Hengxing shared his case as a successful and typical exchange of experience. This is not only a medical achievement, but also a result of his own mind, spirit, sentiment and his long and tenacious fight against the disease. After his retirement, Rongke still tirelessly contributed to the development of casting technology, the construction of key projects and the development of township enterprises.
