On May 29, with a loud noise that cut through the sky, the space laboratory’s supply spacecraft: the Long March 7 Yaosan carrier rocket of China’s second cargo spacecraft "Tianzhou II" was launched at the Wenchang Space Launch Site in China. success. DBQH Light Alloy Technology Group provided some key high-strength, high-toughness aluminum alloy precision parts for "Tianzhou II", and "DBQH" once again made contributions to China's aerospace industry.
DBQH has been a designated manufacturer of aluminum alloy materials for aerospace for many years. This time, DBQH has provided plates, forgings, profiles, pipes and other high-toughness aluminum composite parts for the "Tianzhou-2" cargo spacecraft, which are mainly used as direct parts of the cargo spacecraft assembly. , Key parts such as door components and cargo bulkhead shells.
It is understood that in order to ensure that the "Tianzhou 2" can carry food, cargo, fuel and equipment to the maximum in a limited space, the cargo bulkhead shell needs to be made of materials with light weight, high strength, corrosion resistance, and high precision. . A certain series of alloy plates developed by DBQH not only have the characteristics of high strength, high toughness, corrosion resistance and superplasticity, but also effectively reduce the strength loss of materials and reduce the weight of the aircraft body. To this end, DBQH exerts its advantages in scientific research, and the material R&D team strives to overcome difficulties such as high technical requirements, discontinuous production, and high cost control pressure. From smelting casting to rolling molding, from extrusion to forging, strict quality control, repeated trials and adjustments, Ensure the reliable quality of every process parameter and every batch of products.
In addition to the cargo bulkhead shell materials, DBQH also undertakes the production tasks of key direct components and door components for the final assembly of the "Tianzhou II".
