From the perspective of two bearings, China's manufacturing transformation and upgrading are accelerating towards becoming a manufacturing powerhouse (forging ahead and embarking on a new journey towards becoming a strong nation). The manufacturing industry is the foundation of building a country and a strong nation. Riding on the "numbers" and moving towards the "new", China's manufacturing transformation and upgrading are taking a resolute step. General Secretary Xi Jinping emphasized that "China cannot lack manufacturing at any time", "we must firmly strengthen, optimize, and expand manufacturing and the real economy", and "accelerate the construction of a manufacturing powerhouse". Bearings, the 'joints' of industry. In June of this year, the Liu'ao offshore wind farm in Zhangzhou, Fujian, achieved batch operation and full capacity grid connection of 16 MW wind turbines equipped with domestically produced main shaft bearings. The "China Railway 872" shield machine, equipped with domestically produced 3-meter main bearings, has achieved new success on Line 6 of the Suzhou Metro in Jiangsu Province. Two bearings, from scratch to excellence, reflect the solid steps of Chinese manufacturing from small to large and from large to strong since the founding of New China 75 years ago. With the most complete industrial system in the world, the overall scale of the manufacturing industry has ranked first in the world for 14 consecutive years, and the output of more than 220 products has ranked first in the world... The solid foundation, innovative momentum and surging vitality of Made in China have provided strong support for promoting Chinese path to modernization. From the perspective of a complete industrial system, General Secretary Xi Jinping emphasized that "manufacturing is the lifeline of the national economy" and "China is a major country that must develop the real economy, continuously promote industrial modernization, and improve the level of manufacturing. As the main shaft bearing manufacturer of 16 MW wind turbine, Wang Xinying, secretary of the Party Committee and chairman of the Group, said frankly: "More than 10 years ago, we could not touch high-end bearings, but we would have to bite this" hard bone "no matter how hard it is." To "strengthen internal strength", we established innovative platforms such as State Key Laboratory; Borrowing external forces "and closely cooperating with universities and institutions such as Tsinghua University. From new energy vehicle bearings to wind turbine main shaft bearings, and then to rail transit bearings, new products from Luoyang Axle have been continuously produced and applied to major equipment such as Chang'e, Tiangong, and China's Tianyan. Luozhou has taken the "first-class product" to the extreme, while Tiejian Heavy Industry specializes in the "first-class product" of shield tunneling machines. Developing main bearings and adding the "last piece of the puzzle" for the localization of the shield machine industry chain. In 2019, China Railway Construction Heavy Industry established a research and design institute, and after more than 1000 days and nights, successfully developed the main bearing of a 9-meter shield machine. This is the main bearing of the shield machine with the largest diameter and highest load-bearing capacity in the world, which can be used for the largest model of shield machine in the world Liu Feixiang, Chief Scientist of China Railway Construction Heavy Industry, sighed, "In the past, we used to perform whatever work was needed, and now we can manufacture whatever equipment is needed." Behind the two bearings is the solid confidence demonstrated by China's complete manufacturing industry system. In 1949, the first furnace of molten iron in New China surged out of Angang Steel. Today, China has been the world's largest producer of steel for 28 consecutive years, constantly breaking world records for "hand torn steel"; In 1956, the first Liberation brand truck drove off the FAW production line. Today, China's automobile production and sales have been ranked first in the world for 15 consecutive years, and the production and sales of new energy vehicles have been ranked first in the world for 9 consecutive years. From 'unable to make' to 'able to make' and then to 'made well', we have completed the industrialization process of developed countries for hundreds of years in just a few decades. The manufacturing industry has 31 major categories, 179 medium categories, and 609 sub categories, making it the most complete industry category and system in the world. The resilience and competitiveness of the industrial chain and supply chain continue to improve. In 2023, the added value of the manufacturing industry will account for 26.2% of the gross domestic product and about 30% of the global share. Strong physique and muscular physique, today's Chinese manufacturing has a rock solid foundation and confidence. From the perspective of industrial chain synergy, General Secretary Xi Jinping emphasized that "the core of the manufacturing industry is innovation, which means mastering key core technologies. It must rely on self-reliance and strive for success through independent innovation. The breakthrough of the main bearing of the 9-meter shield tunneling machine is driven by an innovative "relay" involving raw materials, industrial mother machines, engineering applications, and other aspects - "not crushed, not worn", and the material must first be hard enough. Taking the inner gear ring of the main bearing as an example, an 8mm thick ring layer requires a Rockwell hardness greater than 58, and conventional medium carbon bearing steel is far from meeting the standard. What should I do? China Railway Construction Heavy Industry has collaborated with universities to select the optimal steel element ratio after more than 2 years, over 30 sets of tests, and millions of fatigue tests. Multiple steel companies, after dozens of technical discussions and tests, have turned formulas into products. With materials, precision machining is also necessary. The domestically produced 9-meter high-speed CNC gear milling machine, jointly developed by China Railway Construction Heavy Industry and its partners, started research and development in 2020 and will be produced in 2022 with a localization rate of over 90%, helping the main bearings to be successfully produced. The development of 16 MW wind turbine main shaft bearings also relies on the "group operation" of relevant parties. There is no relevant reference material for the main shaft bearings of the large megawatt wind turbine. At a critical moment, the host manufacturer Goldwind Technology sent various types of wind turbine operation data, solving the 'urgent need' Yao Dong, the head of the Wind Power Department of Luozhou Sales General Company, sighed and said, "With solidarity and collaborative innovation, China's manufacturing industry has unlimited possibilities." Large, medium, and small enterprises integrate innovation, industry, academia, and research work together, large aircraft soar in the blue sky, high-speed maglev flies close to the ground, and domestically produced large cruise ships are put into commercial use... A large number of major landmark innovation achievements have led China's manufacturing industry to continuously reach new heights. In 2023, the added value of high-tech manufacturing accounted for 15.7% of the added value of industrial enterprises above designated size, an increase of 6.3 percentage points from 2012. Promote innovation and upgrade traditional industries; Keeping up with the times and strengthening emerging industries; Focusing on the forefront and laying out future industries... China develops new quality productive forces according to local conditions, constantly shaping new driving forces and advantages for development. At present, strategic emerging industries account for about 13% of the gross domestic product, and the number of high-tech enterprises in the country has reached 463000. With the spirit of self-improvement, we strive to climb. Today's Made in China is full of constantly changing creations. From the perspective of high-end, intelligent, and green development, General Secretary Xi Jinping emphasized the vigorous vitality of China's manufacturing industry, "promoting the development of high-end, intelligent, and green manufacturing." With comprehensive improvement and high-end layout, bearing products continue to be "updated": On March 10th, the bearing of the Changbai Mountain 40 meter aperture radio telescope developed by Luozhu passed the acceptance inspection, and in the future, the radio telescope will accurately "guide" the lunar probe. On March 14th, the world's first 25 MW wind turbine main shaft bearing was successfully produced at Luoyang Zhuyan Technology, breaking the global record for the largest single unit capacity of wind turbine bearings. Products should be more high-end, and production should also be more intelligent. Entering the final assembly plant of China Railway Construction Heavy Industry Changsha Second Industrial Park, there is a physical workshop and a digital workshop, both online and offline, synchronized in real-time. Look, this is a set of digital twin images on the front of the shield machine cutterhead, with varying shades of color representing the force and wear of the blades Wang Yongsheng, Deputy Director of the Digital Twin Research Institute of China Railway Construction Heavy Industry, said that by analyzing this data in real time, engineers can optimize the next generation of products in a targeted manner. Two bearings "is a microcosm. Continuously promoting industrial optimization and upgrading, China's manufacturing industry has achieved fruitful results. Climb towards both ends of the 'smile curve'. The energy density of mass-produced power battery cells reaches 300 watt hours per kilogram, which is at the international leading level; The efficiency of the crystalline silicon perovskite stacked cell has reached 34.6%, repeatedly breaking world records; The annual export of new energy vehicles, lithium batteries, and photovoltaic products has exceeded the trillion yuan mark... Chinese manufacturing is accelerating its move towards the mid to high end of the global industry. Advancing towards the deep integration of data and reality. The popularization rate of digital R&D and design tools of key industrial enterprises reached 80.1%, the numerical control rate of key processes reached 62.9%, and the industrial Internet achieved full coverage of industrial categories... The pace of industrial digitalization and digital industrialization has been accelerating. Continuously striving towards' green and low-carbon '. Promoting green and low-carbon transformation, building a green manufacturing system, and cultivating and strengthening green industries... In the first two years of the 14th Five Year Plan, the cumulative energy consumption of industrial units above designated size in terms of added value decreased by 6.8%. Aiming at "high technology", pursuing "high efficiency", and moving towards "high quality", today's Made in China is showing a new look, opening up new spaces, and stirring up new vitality. We will focus on promoting new industrialization, developing new quality productive forces, and maintaining a reasonable proportion of manufacturing industry. We will organically combine the construction of a strong manufacturing country with the development of digital economy, industrial informatization, and accelerate the construction of a modern industrial system with advanced manufacturing as the backbone Jin Zhuanglong, Secretary of the Party Group and Minister of the Ministry of Industry and Information Technology, stated.
