At 17:50 on March 29, 2022, the Long March 6 carrier rocket carrying the "Pujiang-2" and "Tiankun-2" satellites was successfully launched at the Taiyuan Satellite Launch Center in Shanxi, and the two satellites were successfully delivered to the scheduled track.
When the Long March 6 carrier rocket is launched, the tail flame can reach thousands of degrees Celsius. If the performance of the aluminum alloy material required for the rocket body is unstable, it will affect the launch process. At the same time, the tail section of the "Long March 6" is equipped with four boosters. Therefore, the rocket has strict requirements on material stability and reliability. It not only has uniform organization and stable performance, but also requires solidification of process flow and parameters. Ensure that quality requirements are foolproof.
Over the years, ZLDQ Light Alloy Technology Corporation has undertaken the research and development tasks of important aluminum alloy materials such as shell skins, storage tank materials, high-strength body ring forgings, and key structural connector profiles required for China's Long March series rocket bodies.
ZLDQ is the designated manufacturer of aluminum alloy materials for Long March series launch vehicles. Compared with other similar products on the market, a certain series of alloy plates developed by ZLDQ have the characteristics of high strength, high toughness, corrosion resistance and superplasticity, which can resist the rocket during flight. It bears huge pressure, temperature difference and gravity problems in the middle, effectively reducing the strength loss of the material and ensuring that the arrow body is "indestructible".
At the same time, in order to resist various external pressure loads of the rocket, the project has extremely strict requirements on the performance, strength and stability of the ring forgings of the body. In the exploration of heat treatment process, ZLDQ has overcome numerous scientific research problems, gave full play to the advantages of technology and equipment, and optimized the production process.
From the first successful launch of the "Long March-1" carrier rocket to the 412th successful launch of today's Long March series of carrier rockets.
