Shenzhou-12 successfully launched

West Aluminum - West Aluminum Industry Telecom: Chongqing, June 17 (reporter Zhao Congcong, correspondent Peng Yingtang Yuting) at 9:22 on June 17, the high-profile Shenzhou 12 manned spacecraft was successfully launched, and China's manned space project has fully entered the construction stage of the space station. When "Shenzhou 12" was successfully launched, the cadres and workers of SWA who watched the launch could not help cheering. Although this is not the first time that SWA's technology and materials have been applied to China's aerospace industry, many people are still excited. In the glorious history of manned space project, "made in Southwest Aluminum" once again shines brightly.

Shenzhou-12 project is the seventh manned mission in China. Aluminum alloy materials such as plates and forgings provided by SWA are available everywhere in launch vehicles and spaceships. This makes us feel extremely glorious and proud! " Li Yong, general manager and Deputy Secretary of the Party committee of sinal, said with pride.

In the "Shenzhou 12" project, SWA has undertaken the research and development of many kinds of aluminum alloy key materials for launch vehicles, spacecraft, such as high-precision aluminum alloy plates, profiles, bars and forged rings, which are mainly used for the main structures of spacecraft, such as connecting frame, intermediate frame, end frame and spacecraft surface, and the key parts of launch vehicles, such as transition ring, adapter frame, tank, etc. In addition, many parts of shenzhou-12, from the cabin skin to the astronaut seat, also use materials provided by SWA. These key materials have reached the technical indexes of high metallurgical quality and high performance, and have many varieties and specifications and large component sizes.

Shenzhou-12 spacecraft has adopted 4-meter-class rings. Compared with conventional rings, it is not easy for 4-meter-class rings to meet the requirements of the spacecraft. In the trial production process, SWA repeated tests, and finally designed a reasonable deformation ratio to pave the way for subsequent heat treatment. At the same time, in order to eliminate the unqualified performance caused by too large thickness in the process of heat treatment, the majority of technical and production personnel of SWA have overcome many technical difficulties in the production process, such as forging, reaming, rolling deformation matching, heat treatment and stress relief, so as to effectively reduce the residual stress after quenching caused by too large thickness. Through our hard work, we finally ensured that the comprehensive performance of the 4m ring not only met the standard requirements, but also exceeded 15% - 20% of the standard.

Looking back on the successful launching of manned spaceships time after time, "made by Southwest Aluminum" has made indelible contributions. In the Chinese nation's journey of exploring space, the people of SWA will always cherish the unswerving dream of developing aerospace engineering materials, give full play to their technical advantages, and become the main force of solid aluminum alloy material R & D support for national key projects.
