Late at night on November 29, in northwest China, deep in the desert, the Long March 2F Remote 15 carrier rocket carrying the Shenzhou 15 manned spacecraft was launched at Jiuquan Satellite Launch Center. In the hinterland of the Central Plains, Luoyang, the ancient capital, the picture of "Giant Dragon Flying into the Sky" was transmitted to Yang Jin'an, the leader of the electric furnace team of CITIC Heavy Industry Casting and Forging Co., Ltd. through live video. This great craftsman, who was involved in the manufacturing of some special metal castings and forgings for the escape tower system of the spaceship, was full of pride. "The Shenzhou 15 manned spaceship was successfully launched, and I feel honored to contribute to it." Yang Jin'an, who has participated in the manufacturing of special metal castings and forgings related to Shenzhou series spaceships for 13 times, said that it is their goal to protect the "heavy weapons of great powers". As one of the key projects constructed during the "First Five Year Plan" period, CITIC Heavy Industry (formerly Luoyang Mining Machinery Factory), located in Luoyang, Henan Province, has always insisted on building "the most important weapon of the country". From "Shenyi" to "Shenwu", CITIC Heavy Industry has undertaken the important forging research task for Shenzhou spaceship for 15 consecutive times. Yang Jin'an, who has been in the factory for 38 years, is a skilled senior steelworker. He can judge the carbon content of molten steel by scooping a ladle of molten steel from the furnace and throwing it on the ground. Yang Jin'an, who is nearly one meter and eight heads, is not only an expert in business, but also a leader in learning. The report of the Twentieth National Congress of the Communist Party of China proposed that "guided by the national strategic needs, we should gather strength to carry out original and leading scientific and technological research, and resolutely win the battle against key core technologies". Yang Jin'an said that the report touched on his heart. "We should study and implement the spirit of the Twentieth National Congress of the Communist Party of China, and put it in an important position to accelerate the building of a strong manufacturing country." Yang Jin'an believes that as a front-line worker, he should take the spirit of the 20th CPC National Congress as the guide, take root in the front-line steelmaking, overcome difficulties, innovate and create efficiency. Over the years, Yang Jin'an has led his team to continuously overcome the "choke" technical problems in the industry, and has produced a series of "high precision" steel grades such as aerospace steel, special steel, nuclear power steel, petrochemical hydrogenation steel, etc. These steel grades have been successfully applied to the Shenzhou series airships, domestic aircraft carriers, Hong Kong Zhuhai Macao Bridge and other major national engineering construction projects. It is precisely because there are a group of employees who continue to practice independent innovation like Yang Jin'an, and CITIC Heavy Industry has accumulated strong scientific and technological strength. The first high-pressure roller mill, the first 10 million ton complete set of large-scale open-pit mine equipment, the largest and most advanced autogenous mill, semi-automatic mill, ball mill, etc. were launched. CITIC Heavy Industry has continued to achieve "great achievements" in science and technology. "The report of the 20th National Congress of the Communist Party of China proposed to strengthen the deep integration of enterprise led production, education and research, strengthen the goal orientation, and improve the transformation and industrialization of scientific and technological achievements." Wang Xinchang, deputy chief engineer of CITIC Heavy Industry, said that CITIC Heavy Industry put innovation in a prominent position to promote high-quality development of the enterprise. In the first three quarters of this year, CITIC Heavy Industry's revenue was 6.768 billion yuan, up 23.35% year on year. In the past November, compared with the new deployment of "scientific and technological innovation" and "manufacturing power" in the report of the 20th National Congress of the Communist Party of China, CITIC Heavy Industry carried out a systematic, overall and transformative research plan around high-quality development, and clarified the development ideas of "strengthening traditional industries, making new energy industries, making complete industries bigger, and refining emerging industries".
