A few days ago, Shanghai Electric's high-end manufacturing reappeared milestones. The large-scale nuclear power turbine welding rotor has been successfully developed and manufactured as another technological innovation intellectual property rights of Shanghai Electric. It will soon be sent to China's first overseas Hualong No. 1 nuclear power demonstration project in Karachi, Pakistan.
In today's world of vigorously pursuing low-carbon development, nuclear power has gradually become an important choice in the energy sector. Since the 19th CPC National Congress, the key words for the development of China's nuclear power have been adjusted to 'steadily advance the development of nuclear power'. Shanghai Electric has been in over 60 years. In development, it has been closely following the development plan of the national energy strategy and is committed to innovation and promotion of industrial development.
On April 12, Shanghai Electric large-scale nuclear power turbine welding rotor technology conference was held.
Technical report meeting site
Shanghai Electric invited nuclear power investment companies, owner companies, design institutes and domestic universities and leaders and experts as well as industry elites to attend the report meeting to witness this important moment of Shanghai Electric's nuclear power technology development.
At the report meeting, the welding rotor technology team made detailed presentations to the guests on the design and development process of the nuclear welding rotor, and the process inspection technology during production and manufacturing.
Committed to the broad development of nuclear power as a 'national heavy equipment', during the conference, the elite of the Shanghai Electric Welding Rotor team and the guests in various fields of the conference conducted in-depth discussions to discuss the future of nuclear power technology. The guests expressed their recognition of Shanghai Electric's initiative and approval.
Academician of the Chinese Academy of Sciences, Pan Jiyu, a specialist in welding engineering, feels and feels at the scene.
59 years ago, under the auspices of the Shanghai Steam Turbine Plant, I led the welding professional research team of Tsinghua University in cooperation with other scientific research units to carry out the 'Research, Development, and Production of Large Size Welding Welded Rotors', and developed and produced the 6MW gas turbine compressor rotor.
At that time, the living conditions were arduous and the technical conditions were also difficult. In order to ensure that the deformation of the rotor during the welding process did not exceed the specified requirements, we used paper and pen to calculate the deformation during the welding process of each weld to determine the welding sequence. The paper was full of room, but we completed the manufacturing of our country's first gas turbine rotor with high quality, and mastered key technologies with completely independent intellectual property rights.
I am particularly pleased that over the past 50 years, Shanghai Steam Turbine Plant has continued to develop and improve this technology. The welding team of Tsinghua University has once again cooperated with Shanghai Turbine Works for ten years and has been able to produce large-scale nuclear power turbine welding rotors with millions of kilowatts. The technology of the plant is at the top of the world. The level of glory for our country, I also feel very honorable!
Detailed history, Since 1959, the development of Shanghai Electric Welding Rotors has spanned over half a century, covering the first 6MW gas turbine compressor welding rotor in China, 300MW, 600MW, 1000MW thermal power welding rotor and the first large-scale nuclear power welding rotor. .
Shanghai Electric Nuclear Welding Rotor Processing Site
After years of development, Shanghai Electric now has a complete welding rotor technology system, comparable to the world's leading welding rotor technology level, can provide nuclear power users at home and abroad with superior performance, reliable quality nuclear power project welding rotor. Mature and rich performance and manufacturing experience , To provide maximum protection for nuclear power user project cycle.
In addition, with the continuous increase in the capacity of nuclear power turbines in recent years, the low-pressure rotors and the last-stage blades have grown toward heavier and longer-term directions. However, the forging capacity, quality control, and domestic The progress of localization of suppliers can no longer fully meet the needs of nuclear power development. Therefore, the welding rotor will be the 'necessary path' for the development of nuclear power. This will also be the direction of large-scale thermal power turbines. High-parameter units above 630°C and more need to consider dissimilar steels. Welding rotor application.
Shanghai Electric has a world-class nuclear power blade development system and has formed a series of 1250mm to 1905mm products. It can tailor nuclear power engineering steam turbine equipment to meet the different operating conditions and different demands of nuclear power users at home and abroad.
High-end technology leads high-end equipment. Shanghai Electric is committed to development and strives to stay ahead of the development.
