This year's "government work report" mentioned many times to enhance the core competitiveness of the manufacturing industry. The manufacturing industry directly reflects the productivity level of a country. Then, how do state-owned enterprises, which play the role of "ballast" and "pillar", strengthen the supply guarantee of raw materials, key parts and components, maintain the safety and stability of the industrial chain supply chain, accelerate the development of advanced manufacturing clusters, promote the construction of quality power, promote the industry to move towards medium and high-end, and write a new chapter of "made in China"? The reporter conducted interview and Research on this.
from scratch, continuous technological breakthrough and innovation
In the production workshop of CRRC Changchun Railway Passenger Car Co., Ltd., Li Wanjun, the chief technical expert of CRRC, is operating with eyes fixed, and the high-speed railway bogie at hand is full of electric fire. For more than 30 years, Li Wanjun has repeatedly welded high-speed railway bogies day after day. It is understood that bogie manufacturing technology is listed as one of the nine core technologies of high-speed EMUs, which is related to the speed and safety of high-speed railway operation. One of the main reasons why China's high-speed EMUs can "run on the vast land of the motherland" with such high speed and stability is that the bogie technology has made a major breakthrough. Li Wanjun's work has played a great role in the bogie welding post.
Li Jun has developed more than 30 kinds of bogies with the highest welding technology in the world. He has successively developed more than 30 kinds of bogies for the first time in China, and has participated in the development of more than 30 kinds of bogies in the world. This has also enabled China's Bogie Technology to successfully break through the technical blockade of foreign countries and ensure the mass production of EMU bogies.
Today, CRRC Changke has an annual output of more than 9000 bogies, more than the sum of world-famous rail vehicle manufacturing giants such as Bombardier, Siemens and Alstom. The company has an annual output of 180200 EMUs, 4000 urban rail cars, 600 ordinary railway passenger cars, 300 EMUs and 1000 ordinary railway passenger cars, and is expanding urban rail vehicle maintenance and operation and maintenance services.
"China's high-speed railway has developed from scratch, from catching up to leading. As the first generation of high-speed railway workers, they are not only proud, but also feel the responsibility and pressure on their shoulders. Every skilled worker should be highly conscious, strive to be the protagonist of innovation and contribute to the process from made in China to created in China." Li Wanjun said.
In addition to Li Wanjun, CRRC Changke also has a number of advanced models such as national outstanding communist party member and national labor model Luo Zhaoqiang, which provides strong support for China's high-speed railway to lead the development of the industry. Among the employees of state-owned enterprises, there are more outstanding people who contribute to "made in China".
According to the data released by the SASAC at a media briefing in November 2021, there are 56 academicians of the Chinese Academy of Sciences and Chinese Academy of Sciences in only more than 200 "science and reform demonstration enterprises", with a total of 1666 national and 1769 provincial high-level talents cultivated or introduced. The construction has formed a scientific and technological talent team with reasonable structure, excellent quality and strong innovation ability, which provides a strong talent guarantee for the optimization and upgrading of enterprise industrial structure and technological innovation.
"willful and arrogant" to solve the problem of "neck sticking" of major equipment
Recently, many people were stunned by the news that 52 shield machines were assembled in Dawan district during a battle of the national team "brigade". In Guangzhou, China's "South Gate", the central infrastructure enterprise has fully used 52 shield machines, established the world's largest shield construction machine group, and participated in the projects of Guangzhou metro lines 18 and 22.
Such a "arrogant" scene may have been unthinkable in earlier years. A technician engaged in shield machine research told reporters that shield machine technology has been monopolized by foreign Germany and Japan before. Even if Chinese enterprises give a very high price to buy, they can't buy the most advanced model. Moreover, due to the huge of the machine itself, it often delays several days in transportation, and it also takes a lot of time in transaction negotiation. Therefore, many projects in China at that time were delayed in construction time because the machine did not arrive.
Up to now, the main bearings of shield machines with a diameter of 6m and 11m developed by Luoyang LYC bearing Co., Ltd. (hereinafter referred to as Luoyang axis company) have been applied in many places in China, and the problem of "neck sticking" of China's major equipment has been solved.
Among the 626 scientific researchers of Luozhou axis company, there are professional R & D teams headed by well-known experts in the industry, such as aviation precision bearings, military bearings, shield machine bearings, high-speed railway bearings, wind turbine bearings and so on. In recent years, Luozhou axis company has established and improved the innovation network system covering all links and units of the company, and formed an innovation management system including intellectual property protection, achievement transformation and performance appraisal. Relying on national innovation platforms such as national enterprise technology center, the only national key laboratory in the industry and national recognized laboratory, it has successively established an "industry university research and application" innovation platform with colleges and universities and scientific research units such as Tsinghua University, Xi'an Jiaotong University, Henan University of science and technology, aviation Power Research Institute and Railway Research Institute, actively participated in tackling key scientific and technological problems in the industry and continued to lead technological innovation in the industry.
Yu Haibo, deputy secretary of the Party committee and general manager of Luozhou axis company, said that during the 13th Five Year Plan period, Luozhou axis company undertook 27 national scientific research projects, reaching the international advanced level and China's leading level, and its innovation ability continued to lead the industry. The average annual R & D investment ratio is 5.3%, and the compound growth rate of net profit reaches 30%, which has made a positive contribution to accelerating the industrial base represented by the bearing industry.
Li Wu, deputy director of China Statistical Information Service Center, pointed out that manufacturing investment, as an important part of industrial investment, can effectively stimulate the growth of industrial fixed asset investment. Enterprises should be encouraged to focus on basic parts, basic materials, basic processes and basic software of the manufacturing industry, increase investment layout, speed up the filling of the weaknesses of the industrial chain supply chain, strive to break through key technologies and enhance the toughness of China's industrial chain supply chain.
strong forces jointly promote the industry to move towards medium and high-end
The reporter learned from China Huadian that at the end of last year, the "Huadian Ruifeng" independently controllable 3MW onshore wind power main control system jointly developed by Guodian Nanjing Automation Co.Ltd(600268) Huadian Gansu company, Huadian Suzhou Electrical Apparatus Science Academy Co.Ltd(300215) and China Electronics Feiteng company was successfully put into operation in Gansu Yumen heiyazi wind farm.
The relevant person in charge of the project said that the operation is a major achievement of the joint innovation of central enterprises. Through joint research, "Huadian Ruifeng" has broken through the technical difficulties such as special application conditions of wind power and CPU share. The product performance index, environmental adaptability and anti electromagnetic interference ability have reached the leading level in China, and has 100% independent intellectual property rights. It has realized the independent control of software and hardware in the whole range from core CPU, operating system, compilation environment to control strategy, and successfully broke through a number of foreign technical monopolies, The "Huadian Ruifeng" 3MW onshore wind power autonomous and controllable wind power main control system with completely independent intellectual property rights, ft-2000 processor and domestic embedded real-time operating system has been developed.
The above-mentioned cases of joint innovation of central enterprises are not individual cases. The joint innovation of central enterprises has promoted the construction of a quality power and promoted the industry to move towards medium and high-end.
At the consultation meeting held by the Ministry of science and technology and the state owned assets supervision and Administration Commission of the State Council on March 1 this year and the Symposium on jointly cultivating and building leading enterprises in science and technology, Hao Peng, secretary and director of the Party committee of the state owned assets supervision and Administration Commission, pointed out that in recent years, the state owned assets supervision and Administration Commission and the Ministry of science and technology have established a strategic cooperation mechanism, the two sides have further coordinated resources, supported and guided a number of central enterprises with strong technological innovation ability and strong industry leading role to take the lead in the formation of innovation consortia, The construction of a national technological innovation center and the implementation of key core technologies have made new important progress and remarkable achievements, and made positive contributions to the construction of a scientific and technological power.
Weng Jieming, deputy director of SASAC, previously said that central enterprises should focus on their main industries, promote intensive development, improve development quality, realize industrial synergy and strengthen advantageous industrial clusters; We should develop intelligent manufacturing, continue to promote the transformation and upgrading of traditional industries, vigorously promote the development and growth of emerging industries, and promote industrial optimization and structural adjustment; We should improve our innovation ability, strive to build an important place for tackling key problems in intelligent manufacturing, an important source of original technology and a highland of scientific and technological talents, and achieve self-reliance and self-improvement in science and technology.
