West Aluminum - West Aluminum Industry Telecom: At 4:30 on November 24, Hainan Wenchang launch site, the Long March 5 remote 5 rocket lifted up the chang'e-5 lunar probe. Subsequently, "chang'e-5" successfully entered orbit and launched successfully! "Changdu" has made a large number of "high-quality aluminum" materials from "Wujian". In the course of human exploration of the vast universe, Swaziland has once again written a new chapter.

China's lunar exploration project is divided into three steps: circling, landing and returning. Chang'e-5 will carry out the lunar sampling and returning mission and complete the last step, return. Therefore, this mission is of great significance and is the final work of the third phase of the lunar exploration project. The success of the launch has laid an important foundation for the successful completion of the third phase of the lunar exploration project. The "chang'e-5" launched this time is heavier, about 8.2 tons, which is more than twice the weight of the previous "chang'e-4" lunar probe. Therefore, it is one of the most complex and difficult tasks in China's aerospace field to launch the "chang'e-5" rocket, which has the largest carrying capacity in China, and send it to the Earth Moon transfer orbit about 200 km near earth point and about 400 000 km apogee One. The launch mission is an important national engineering task which was confirmed earlier after the project of "chang-5" rocket project. After 10 years, "big rocket" and "Chang'e" finally went to the moon hand in hand, attracting the attention of the whole country and the world.

SWA's aluminum alloy forging rings with diameters of 5 meters and 3 meters and high alloy plates of various specifications are used in the key parts of "chang-5" rocket, such as transition ring, transfer frame and tank, accounting for more than 80% of the aluminum required for the rocket body structure. In 2007, SWA overcame the technical difficulties of large ingot casting, forging and blooming, ring rolling and cold deformation, and successfully forged a 5-meter diameter transition ring. Its original core forging technology filled in the domestic blank and forged a key "ring" for the "chang-5" rocket. In order to meet the new requirements of high-quality development of aerospace industry, SWA started the quality improvement work of the second generation of 5-meter ring in 2018, and successively overcame a number of technical difficulties such as forging and rolling deformation, heat treatment and cold deformation, so that the elongation and comprehensive performance of the second generation of 5-meter ring were increased by 20% and 10% compared with the first generation, and it was successfully put into use in 2019. In 2016, SWA successfully developed a 10 meter class super large aluminum alloy integral ring, which broke the world record and solved major key technical problems for China to launch heavy-duty launch vehicles in the future.

On the "chang-5" detector, SWA provides high-precision and sophisticated aluminum materials such as bars, skin plates, free forgings, super large size plates and forged rings, which are mainly used in the key parts of "chang-5" landing system, telescope system, transfer mechanism and solar panel. Among them, 22xx, 2axx and other plates on the "Chang Wu" are all from SWA. SWA adopts the "three fixed" principle of fixed process, equipment and personnel to carry out the follow-up production, which effectively overcomes the major technical problems such as unevenness, same plate difference and high surface requirements, and meets the urgent needs of major national projects.

SWA provides high-precision, high surface and high-performance aluminum alloy materials for the "chang-5" and "chang-5" projects. It has the characteristics of many varieties and specifications, large component size, complex shape and difficult process. It has effectively solved a series of scientific research problems such as melting casting, hot processing and heat treatment, and its comprehensive performance of specific strength, specific stiffness and low temperature resistance has reached the international advanced level It meets the strict requirements of aerospace engineering construction.

"In 2004, China officially launched the lunar exploration project, which was named" Chang'e project ". In 2007, "Chang'e-1" sent the moon back to the motherland; in 2010, "Chang'e-2" became the farthest spacecraft in China; in 2013, "chang'e-3" became China's first unmanned probe for soft landing of celestial bodies outside the earth; in 2018, "chang'e-4" became the world's first spacecraft successfully landing on the back of the moon; Chang'e-5, launched in 2020, will carry out lunar surface sampling and return mission. "Chang'e" series of moon journey, SWA people have been bold innovation, "made by SWA" is indispensable.

"Jiaolong" entered the sea, "Shenzhou" flew into the sky, "Chang'e" flew to the moon, "Tianyan" sounding In every national key project of aerospace and national defense, SWA has significant technological breakthroughs and innovative material guarantee. "This is the responsibility and responsibility shouldered by SWA, which is the" national heavyweight ". Because of these key" aluminum ", we can avoid being" stuck in the neck "and ensure the safety of key projects in key areas of the country. The words of Li Yong, general manager and Deputy Secretary of SWA, are loud.
