In the early morning of October 16, the Long March 2 F Yao 13 carrier rocket carrying the Shenzhou 13 manned spacecraft was precisely ignited and launched at the Jiuquan Satellite Launch Center at the scheduled time, successfully sending 3 astronauts into space! “China Aluminum Manufacturing” once again played the role of the mainstay in serving the national strategy. East Light, Southwest Aluminum, and Northwest Aluminum provided guarantees for the materials required by my country’s aerospace industry.
The three astronauts carried by the Shenzhou 13 spacecraft embarked on a 6-month space journey. The time span is unprecedented in the history of our country. The aluminum Alloy materials used in the Shenzhou 13 are required to be absolutely stable and reliable, that is, the organization Uniformity and stable performance require the curing of process flow and parameters, and the quality assurance is foolproof.
The aluminum alloy materials used by Dongqing in the orbital cabin shell structure, skin, return cabin side wall metal shell, seat metal structure, portable water storage bracket, and upward load object cabinet board of the Shenzhou 13 spacecraft are all used. For the exclusive supply, it has once again raised the silver backbone for our country to explore the space world. In order to overcome the problem of substandard toughness of a certain alloy sheet used for the Shenzhou 13 spacecraft, the Dongqing R&D team actively benchmarked with advanced units, summed up and refined high-quality experience, summarized and solidified the process operation process, and realized the high-quality delivery of the alloy sheet. . The aluminum alloy materials provided by Dongqing have the characteristics of high strength, high toughness, corrosion resistance and superplasticity. They can withstand huge pressure, temperature differences and gravity problems during flight, which can effectively reduce the strength loss of materials and reduce the weight of the aircraft body. .
The aluminum alloy materials provided by Southwest Aluminum for spacecraft and rockets cover forgings, plates, profiles, pipes and other categories and more than 10 specifications and varieties. The key parts of the structure and the transition ring, transfer frame and storage tank of the launch vehicle account for more than 60% of the total aluminum material supplied. Among them, the aluminum materials of the spacecraft skin, metal shell of side walls, metal structure of tables and chairs, brackets of portable water storage tanks, left plate of upward cargo container, shell structure of track cabin, oil circuit and gas circuit, etc. are made of Southwest Aluminum. , A certain type of diameter aluminum forging ring for the main structural parts of the arrow body is also exclusively supplied by Southwest Aluminum. These high-alloyed aluminum materials have the characteristics of many varieties and specifications, large component sizes, complex shapes, and difficult processes. Southwest Aluminum has effectively solved a series of technological problems, obtained a series of scientific research achievements such as melting casting, hot processing, and heat treatment, and conquered materials. A number of key technical difficulties in R&D and production.
Northwest Aluminum provided materials such as bars for valve housings and industrial profiles for stringers for the Long March 2 F Yao-13 rocket. The wall thickness difference of the profile is large and the shape is complex. It is difficult to ensure high-precision shape and position tolerance by ordinary processing methods. Northwest Aluminum adopts a special material method to ensure high precision; the extrusion process is optimized during bar production, and precise matching Compared with trace elements, it ensures uniform grain refinement. On the Shenzhou 13 manned spacecraft, there are bars for the cabin turntable with good thermal strength and high strength provided by Northwest Aluminum, as well as industrial profiles with medium strength, good processing performance, corrosion resistance, and welding performance. High-precision aluminum alloy materials such as return cabin seat buffer materials.
Entering the first year of the “14th Five-Year Plan”, Chinalco Group will give full play to the advantages of scientific and technological innovation, and increase the technical transformation of existing production equipment, from the improvement of equipment accuracy to the improvement of product performance, to ensure the development of China’s aerospace industry, and to promote the development of China’s aerospace industry. Serving the national strategy R&D and production of more key aluminum.
