Facing the impact of the financial crisis on enterprises, Chinalco Southwest Aluminum, as the vanguard of China's aluminum processing industry and the national aerospace material supply base, has always been committed to protecting the country’s urgent needs and has devoted itself to the development of supporting materials for domestic large aircrafts. .
A few days ago, while Southwest Aluminum obtained orders for the first batch of large aircraft supporting materials, a major breakthrough was made in the development of the first batch of large-size aluminum alloy materials. This indicates that Southwest Aluminum has the capability to develop aluminum alloy products with large specifications and high performance requirements. Large domestic aircraft manufacturing has taken a big step forward.
Recently, the aluminum alloy fuselage frame forging materials of the first batch of domestically produced large aircrafts were successfully produced on the 30,000-ton hydraulic press of the Southwest China National Treasure National Equipment. At the production site, the company’s veteran model worker and former researcher who has participated in the development of the Shenzhou-series spacecraft and the supporting materials for the project around the moon, and her research and development team have always been on the spot and are in control of the production situation. Looking at the aluminum alloy fuselage frame forgings of the previous large aircraft, he gradually walked down the molding line, and Rong Rongrong said proudly: Let the domestic large aircraft fly to the blue sky as early as possible has always been our dream, as a grassroots scientific and technical worker. I feel really excited today and I am very proud to see the large aircraft forgings that we have developed by hand.
A large aircraft is a transport-type aircraft with a total weight of more than 150 tons. Currently, only the United States, four European countries and Russia have the ability to make large aircraft. The development of large aircraft is a highly sophisticated project, each requiring a large amount of aluminum alloy material. After the launch of the domestically produced large-aircraft project, Southwest China will provide forging products for Boeing and provide superior research and development advantages for advanced aluminous materials such as the "Shenzhou series" spacecraft and other key national aerospace projects. It will intervene in advance and set up a leading company for advanced aluminum alloy materials for large aircrafts. The team and the large aircraft office began pre-research and trial production of key special aluminum alloy materials for large-aircraft projects and made full efforts to tackle the problem.
The processing technology of ultra-large force components such as large aircraft fuselage frames has always been the cutting-edge technology of the international blockade. In the absence of drawings, and the absence of technical information, the majority of scientific and technological personnel at Southwest Aluminum are responsible for the development. Through exploration and innovation in practice, we boldly developed and developed a composite strong deformation process. After many trials and debugging, we finally broke through the problems of inadequate deformation capability of existing auxiliary equipment and incomplete deformation of the product. We succeeded in making the product thickness jump from 120 MM to 300MM increases the thickness by 2.5 times at one stroke, filling the gap that can not produce 300MM ultra-thick components at home and meeting the needs of large aircraft. In the development work, they also conquered a number of technical problems, applied for a number of patents, laid the technical foundation for airworthy certification of large aircraft materials. Fang Qingwan, deputy director of Southwest Aluminum Forging Plant, told reporters: Southwest China can become a supplier of domestic large aircraft supporting materials, relying on its strong R&D strength. With the continuous development of the aviation industry, the requirements of large aircrafts for materials have become higher and higher. This has also given our scientific and technical personnel more stringent requirements. We will speed up the research and development of key technologies for large aircraft materials, strive to complete various scientific research tasks as soon as possible, and strive to promote the localization of large aircraft materials.
During the development of Southwest China's full-scale research and development of large aircraft supporting materials, State Councilor and Minister of Defense Liang Guanglie, Chairman of China Commercial Aircraft Company Zhang Qingwei, and Deputy Director of the National Defense Technology Industry Bureau Li Qiegui successively came to Southwest Aluminum to inspect and guide the work of Southwest China to protect the country’s urgent needs. He has served as a leading force in the research and development of aluminum alloy materials for domestic large aircrafts and has given high evaluation to the advantages of aerospace research and development.
It is understood that Southwest Aluminum has obtained a total of more than 100 kinds of large aircraft aluminum alloy supporting material production orders with a total weight of about 700 tons. At present, Southwest Aluminum is closely tracking the research and development needs of large aircraft-related design and equipment manufacturing units, and continues to refine the research and development of key materials such as special aluminum alloy plates, profiles, and forgings required by the “big aircraft†project. In addition, Southwest Aluminum is stepping up construction of an important 4.3-meter-thick-thick-plate hot-rolled production line and a large tonnage-stretching machine of more than 12,000 tons. After the project is completed, SWA will have large-scale aluminum and aluminum alloys for large aircrafts. Aluminum plate production capacity, pioneering and innovative.
The successful development of the first batch of domestically-produced large aircraft supporting new materials was just a beginning. Zhao Shiqing, general manager of Southwest Aluminum, had deeper thinking in the future. He said: Large domestic aircraft is a large and complex system engineering, and a generation of materials determines a generation of aircraft. Alloy materials are one of the key aspects of large aircraft engineering. We will always adhere to the principle that national needs are high and national interests are paramount. We are committed to becoming the main force for material research and development support for domestic large aircrafts, advanced planning, advanced construction, and advancement. Development, and strive to make our domestic large aircraft equipped with a large number of "China Aluminum Aluminum Company" aluminum alloy materials soar as early as the blue sky.
