The 35 scientific research results of the State Machinery Reinstallation and China Second-Hong Kong html were on the list, including 1 special prize, 1 first prize, and 3 second prizes.
Machinery Industry Science and Technology Progress Award is jointly sponsored by the China Mechanical Industry Federation and the China Mechanical Engineering Society . It is awarded to individuals or organizations that have made outstanding contributions to promoting scientific and technological progress and economic and social development. This award is the highest honor in the award of scientific and technological achievements in the machinery industry. The 2021 China Machinery Industry Science and Technology Award selected 3 special prizes, 36 first prizes, 126 second prizes, and 201 third prizes.
"Key Techniques and Engineering Applications of 80,000 Tons Forging Press" led by China Secondary and participated in the research of China Heavy Duty Academy won the special prize of the China Machinery Industrial Science and Technology Progress Award.
80,000 tons die forging press
China Secondary and China Heavy Duty Institute and other domestic research institutes jointly researched and developed, and after nearly ten years of hard work, they broke through multiple manufacturing limits and created several world firsts. They successfully developed 80,000 tons of die forging press , providing core key forgings for new aircraft and engines in my country. Relying on the platform, we have broken through the bottleneck of domestic large-scale precision die forging parts and overcome the problem of high-quality forging of super-large aviation die forgings. Now we have mass-produced key large-scale die forging parts required for various new aircraft. The successful development of
, a series of scientific research products, marks a major breakthrough in the complete design and manufacturing of super-large load-bearing, high-precision large die forging press equipment, as well as the manufacturing of large, overall and precision die forging parts, and plays a huge role in the national economy and national defense construction.
"R&D and Application of Key Postprocessing Equipment and Core Production Technology" won the first prize of the Science and Technology Progress Award by the China Heavy Duty Institute.
R&D and application of key post-processing equipment and core production processes of high-end metal plate belts
This project pioneered the integrated design of the full-process post-processing process and its key equipment technology, developed high-precision disc shear overlap amount and lateral gap adjustment mechanism and setting technology and high-precision mechanical equipment reversing gap compensation control system, established a shear process database based on expert system and big data support, and developed a comprehensive control technology for edge quality, plate shape and surface quality of metal plate belt finishing process, solving the key technical problems that restrict the independent development of my country's automobile industry, ultra-high voltage transmission and transformation industry and other industries to the high-end independent development. The successful research and development and promotion of the
project has realized the localization of high-end metal plates such as high-quality automotive exterior panels and high-magnetic inductance -oriented silicon steel , promoted industrial upgrading and structural optimization, and met the major needs of various fields of my country's high-end manufacturing industry.
Dual Equipment hosted the "Overweight, super long boiling bed residual oil under high corrosion medium hydrogenation reactor " project won the second prize of the Science and Technology Progress Award.
The world's heaviest (2400 tons) boiling bed residue forging and welding hydrogenation reactor for shipment
This project is based on a hydrogenation reactor (1203-R-8101) of the boiling bed residue hydrogenation device of 2.6 million tons/year. Its manufacturing technology reaches the advanced level of similar products in the international category, solving the problem of the large thin-wall circulation cup of stainless steel inner parts easy to deform, assembly and welding between large distribution plates and cylinders, and solving the welding technical problem of the inner weld height of no more than 0.1mm after the butt welding of small steel pipes. For the first time, the domestic research and development of overall manufacturing technology in the factory is achieved.
This device can increase the conversion rate of residual oil from the original 40-50% to 85%, making my country's petroleum refining technology among the world's leading companies, strongly supporting the implementation of the national energy strategy, and is a veritable "national weapon" for national energy security and beautiful China construction.
China Heavy Machinery Leading Project "Research on the Engineering Characteristics of Carbon Slate in Southeast Asia and Surrounding Rock Stability and Safety Control Technology" won the second prize of the Machinery Industry Science and Technology Progress Award.
This project relies on the Southern Russia Four Hydropower Station in Laos to conduct research.The total length of the water diversion tunnel of the project is 16.5km, and the total length of carbon slate has been revealed to be as long as 4.1km, accounting for 25% of the total length of the tunnel. Such a large-scale tunnel project through carbon slate is very rare in the world. In order to solve a series of technical problems in the construction of carbon slate tunnels, the project team has formed a complete set of technologies through a series of research, which not only saves more than US$15.86 million in project investment, but also has great significance for ensuring local energy security, promoting environmental protection, and promoting China-Laos cooperation. The results of the
project have been promoted and applied in many transmission and transformation line projects of Laos China-Laos Railway, Laos and Cambodia . The results have been evaluated to generally reach the industry-leading level, significantly improving the level of scientific and technological innovation in soft rock tunnel construction, setting an example in China and the world.
"High-performance, low-energy consumption, heavy-duty servo hydraulic cylinder and its system development and application" won the second prize of the Science and Technology Progress Award.
High performance, low energy consumption, heavy-duty servo hydraulic cylinder and its system development and application
A series of innovative achievements of this project have successfully solved the functional characteristics of high-frequency, heavy-duty servo hydraulic cylinder and its system, the functions of high-performance flexible working conditions based on digital-to-analog control, and the connection technology of user on-site data through industrial Internet, which plays an important supporting role in promoting the upgrading of mechanical equipment, the optimization of high-quality products, and the intelligence of production lines. At the same time, the servo hydraulic cylinder and its system are solved as the key core equipment for the production of high-value-added casting billets in the field of continuous casting, and provide technical guarantees for the development of modern high-end continuous casting with my country's independent intellectual property rights. The technical achievements of the
project have been successfully applied in many major continuous casting projects at home and abroad, significantly improving the core technical independence, international influence and product competitiveness of domestic complete equipment.
