In the field of shield machine/TBM R&D and manufacturing, its comprehensive strength and domestic market share have ranked first in China for nine consecutive years, and its production and sales volume have ranked first in the world for four consecutive years; In the field of research, development and manufacturing in the bearing industry, it has the largest bearing enterprise in the country, forming a relatively complete industrial system, and is a base of advanced technology and high-end talents in the bearing industry in China. On the way to advanced manufacturing industry and strong industrial province, shield and bearing have become two dominant industrial development directions in Henan Province.

On the morning of March 15th, the "Henan Advanced Manufacturing Report Conference", guided by the China Society of Mechanical Engineering and Henan Association of Science and Technology, and sponsored by the Henan Society of Mechanical Engineering, was held at the Zhengzhou International Convention and Exhibition Center. At the meeting, discussions were conducted around the technical development and key technology breakthroughs of large diameter shield tunneling machines, the research and development and industrialization process of high-speed railway bearings in China, and the digital twin technology to assist the research, design, manufacturing, and management of mechanical equipment. The "Henan Shield Industry Development Report" and "Henan Bearing Discipline and Industry Development Research Report" were issued.

The "Henan Shield Industry Development Report" was released by Sun Zhihong, President of China Railway Equipment Major Special Research Institute, and provides a detailed description of the development process of shield machines, the layout of the shield industry in Henan Province, and new products and technologies in the future.

The report points out that the shield machine industry in Henan Province started early and developed rapidly, becoming a major and powerful province in the research, development and manufacturing of shield machines/TBMs in China. At present, Henan Province has basically formed a whole industrial chain integrating product design and development of tunnel boring machines, localization of key components, product manufacturing and remanufacturing, technical consulting, technical services, equipment leasing, tunneling services, accessories sales, etc.

Currently, Henan Province has formed a complete shield industry system and product categories, with products applied to more than 50 urban tunnel construction projects in China, and exported to 28 countries and regions such as France, Italy, Poland, Malaysia, Singapore, Lebanon, Israel, and Vietnam. Its comprehensive strength and domestic market share have ranked first in China for nine consecutive years, and its production and sales volume have ranked first in the world for four consecutive years, Become a major and powerful province in shield machine R&D and manufacturing in China. As of 2020, there are about 3500 shield machines in the national market, with China Railway Equipment occupying nearly 1000 sets, accounting for about 30%. Among them, there are about 350 shield machines in Henan Province, with China Railway Equipment products occupying 37% of the market.

Among them, the State Key Laboratory of Shield and Tunneling Technology was founded in Zhengzhou in 2012. It has the high-end innovation platform of "Henan International Joint Laboratory of Shield and Tunneling Technology" and "Henan Underground Engineering Technology and Equipment Innovation Group", which is the only national public research platform, academic exchange platform and talent training platform in the field of shield and tunneling technology in China.

China Railway Engineering Equipment Group Co., Ltd., as a pioneer and leader in China's shield/TBM (full face tunnel boring machine) industry, is also a comprehensive equipment service provider with the most core technologies and the most comprehensive product categories in China's shield/TBM industry. Its market share has remained the first in China for ten consecutive years, and its production and sales volume has been the first in the world for five consecutive years. The export volume of products accounts for more than 80% of China's exports of similar products, It has become the first brand of shield machines exported overseas in China.

The "Research Report on the Development of Henan Bearing Discipline and Industry" was issued by Ma Wei, the supervisor of Henan Society of Mechanical Engineering. It systematically introduces the current situation of bearing technology and industry development at home and abroad, as well as the current situation, existing problems, opportunities and challenges faced by our province's bearing discipline and industry, and puts forward suggestions for the structural adjustment and high-quality development of our province's bearing industry during the "14th Five Year Plan" period.

The report points out that bearings are the core and key basic components of mechanical equipment, and their technical level represents a country's industrial level. The technology and development level of high-end bearings directly affect national security. After more than 70 years of development, China has become a major bearing manufacturing country in the world, with bearing output ranking third in the world, and is moving towards becoming a powerful bearing country in the world.

The bearing industry is a traditional advantageous industry in Henan Province. It is mainly distributed in Luoyang City, Xinxiang City, Fangcheng County, and Jiyuan City. In 2021, there were more than 400 enterprises in the bearing industry in the province, including 106 bearing and upstream and downstream enterprises above designated size, with over 50000 employees, achieving an annual main business income of 32 billion yuan.

Luoyang is one of the five major industrial clusters in China. It has comparative advantages in high-end precision bearings, robot bearings, oversized turntable bearings, railway bearings, metallurgical machinery bearings, mining machinery bearings, petroleum equipment bearings, machine tool bearings, aerospace bearings, as well as rolling bodies, precision bearing testing instruments and test equipment, and has formed a relatively complete industrial system, It is also a base of advanced technology and high-end talents in the bearing industry in China, known as the "Holy Land" of bearings by industry insiders.

Henan University of Science and Technology is the only university in the bearing industry that cultivates undergraduate, master, doctoral, and postdoctoral talents in bearings. It has established a national and local joint engineering laboratory for high-end bearing tribology technology and application; The predecessor of Luoyang Bearing Research Institute is a comprehensive research institute in the bearing industry in China. It is a high-tech enterprise that develops "high, precision, cutting-edge, special, and specialized" bearing products for key host machines in various fields of the national economy and national defense construction; Luoyang LYC Bearing Co., Ltd. was once the largest bearing enterprise in China, and has established a State Key Laboratory for aviation precision bearings; China Machinery 10th Institute International Engineering Co., Ltd. is the only bearing factory design institute in China; Luoyang Xinqianlian Slewing Bearing Co., Ltd. is mainly engaged in the R&D and manufacturing of large-scale slewing bearing products, wind turbine bearings, and shield machine main bearings. It is an innovative leading enterprise serving the industries of wind power generation, marine equipment, port machinery, marine machinery, and shield machines.

It is understood that the "2023 Central China (Zhengzhou) Equipment Manufacturing Expo" (referred to as the "25th Central China Manufacturing Expo"), sponsored by the China Society of Mechanical Engineering and the Henan Association of Science and Technology, was held at the Zhengzhou International Exhibition Center from March 15 to 18, 2022. As the industry professional exhibition with the longest history (held every spring and held 24 times), the largest scale and the most professional exhibition in the central region, it has attracted nearly 1000 exhibitors from home and abroad, showcasing metal cutting machine tools, laser cutting, sheet metal equipment, forging machinery, machine tool functional components, welding equipment, surface treatment, heat treatment, industrial automation and instrumentation, robots, hydraulic transmission technology products Exhibits such as air compressors comprehensively showcase new products and technologies for industrial equipment and provide one-stop comprehensive solutions for the industry.
