Zebian writer: Xiaoguang Hong WASHINGTON March 23, the CPC Central Committee, China Commercial Aircraft Company chairman and party secretary Zhang Qingwei led his unit into the Southwest Aluminum business investigation and study, the aluminum company and SWA in the large aircraft project he hopes In terms of basic materials, we will continue to play a major role in the deployment of domestically produced large aircrafts with high-quality domestic aluminum materials. Southwest has always been the first to meet the national needs, and has undertaken a number of key projects in the country's research and development work. Before the country launched the large-aircraft project, Southwest China took the initiative to contact the relevant units and carried out preliminary preparations for the project. At the same time, in order to ensure the smooth development of material for large planes, Southwest China attaches great importance to it, and has established the leading group of special aircrafts and special offices for general aircrafts with the general manager as the team leader, and has applied human, material and financial resources to large aircraft materials. The research and development work give great support. Southwest China also vigorously carried out the certification of international aviation materials. Based on the certification of Boeing for precision aviation forgings and forgings production, it vigorously expanded the extension certification of plates and extrusion materials and obtained the BVC (French Bureau of International Inspection). The certification certificate has accumulated valuable experience and laid the foundation for China to establish its own certification system for aviation aluminum alloy materials. In the process of organizing the preparation of commercial aircraft, Chinalco not only continued to support the implementation of major national projects, but also directly participated in the project through the innovation of the mechanism and system. Chinalco and Southwest Aluminum are brave enough to take responsibility and provide strong guarantees for the smooth implementation of large aircraft projects. Earlier this year, China Aluminum Corporation signed a strategic cooperation agreement with China Commercial Aircraft Co., Ltd. to jointly promote the construction of large-scale aircraft projects in China. Under the leadership of Chinalco, Southwest China will continue to shoulder the heavy responsibility of revitalizing the national aluminum processing industry, in-depth study and practice of the scientific concept of development, to create a world-class aluminum processing enterprises, will not give up, to undertake the main research and development of aerospace and defense military materials Responsibility of the military remains unchanged, with confidence, determination, and ability to complete the R&D and production tasks of domestically-made large aircraft-related materials, and to deliver a qualified and satisfactory answer to the party, the country, and the people with outstanding results, which will serve as an aerospace enterprise for China. We will make greater contributions to the development of blue sky as soon as possible with domestically produced large aircrafts, and strive to build world-class aluminum processing companies. Zhang Qingwei said that for many years, Southwest China has worked closely with relevant state departments and units to overcome difficulties, provided a lot of sophisticated aluminum alloy materials for aerospace and national economic development, and made outstanding contributions. Among the major special projects identified by the country, large-aircraft projects have been placed first, and special emphasis has been placed on strengthening the implementation of major special projects represented by large-aircraft projects. It is necessary to use scientific and technological innovations to enhance the country’s overall national strength and promote the development of the country. . To this end, the state has established China Commercial Aircraft Co., Ltd. The State Council has proposed that the large-aircraft project should play the “three-in-one†role, that is, drive the development of the aviation industry, related industries, and basic industries. In order to do a good job in large-aircraft projects, materials are the foundation and materials must go first. It is imperative that the strategic cooperation agreement be implemented well and that each person should do a good job of the work undertaken. At the same time, the development of materials is inseparable from other aspects of the work and must be carried out simultaneously. Moreover, the unit that undertakes the material development work should push the work forward as far as possible, and must coordinate the development of the material under the overall coordination to provide qualified and reliable material protection for the large domestic aircraft. Zhang Qingwei hopes that Chinalco and Southwest Aluminum will work together with Chinese commercial aircraft companies to jointly develop large-aircraft projects. Southwest China will continue to carry forward its fine traditions, overcome difficulties, and become the main force in the development of aluminum alloys for domestic large aircrafts. China National Aluminum Corporation deputy general manager Hao Hong, the head of China Southwest Aluminum Corporation also accompanied Zhang Qingwei and his party to visit the forging plant, hot rolling production line, thin plate plant, aluminum foil plant, plate production line, new 50 tons of casting production line. During the visit, Zhang Qingwei listened to the report and carefully inquired about the production and development of the aluminum alloy materials required by the large aircraft. He expressed his affirmation of the achievements of Southwest Aluminum in recent years. During the visit to the hot rolling line, Zhang Qingwei also happily operated the rolling mill in the operation room and rolled out an aluminum alloy sheet used to make aircraft skin. The personnel involved in the survey also exchanged information on the production of aluminum alloy materials for large aircrafts. (Xiao Guanghong
