"Thank you for your contribution to the launch of the newly developed long march seven launch vehicle in china!" In recent days, a letter from the letter of the China Aerospace Science and Technology Corporation, let Pangang Group Jiangyou Changcheng Special Steel Co., Ltd. (hereinafter referred to as climbing a long special) engaged in special stainless steel developed by research staff and workers who feel proud. This is their second received congratulatory letter of China Aerospace Science and technology group the.
June 25th in this year, China's new carrier rocket Long March 7 in new Hainan Wenchang space launch site launch, the success of the payload into orbit, as a prelude to the China Manned Space Engineering space lab mission.
The long march rocket number seven in China with independent intellectual property rights of two new liquid oxygen / kerosene high-pressure afterburning engine is our current near earth orbit carrying capacity of the largest rocket, greatly enhance the overall strength of China's space. Pan Long specially designed for China's new generation of rocket engine, the LOX / kerosene high-pressure staged combustion engine developed a variety of new materials, these materials for liquid oxygen / kerosene high-pressure fill smoothly developing of combustion engine has laid a solid foundation.
According to climb long Technology Center Laboratory for stainless steel and special person in charge, s series of low-temperature steel is a LOX / kerosene space engine with steel, for climbing a long special exclusive exclusively for varieties, mainly for manufacturing in China a new generation of high thrust rocket engine in a variety of important parts. This steel production technology requirements are very high, difficult to control the composition of the.
Since 1997, the state set up a long march a new generation of high thrust rocket engine, liquid oxygen and kerosene high-pressure staged combustion engine material research projects, R & D of five kinds of new materials, climbing a long special bear the three kinds of materials research and development tasks. In the years of unremitting research and development process, climbing long special continuous improvement of technology, optimize the process, so that the performance of new materials continue to improve and upgrade, and can stabilize the supply.
In September 20th last year, 7 hours 01 minutes, China's new carrier rocket Long March six at the Taiyuan Satellite Launch Center ignition launch, the success of the 20 tiny satellites into space. The launch mission a complete success, not only marked the added a new member of the Chinese long march rocket family, but also to create a new record of China Aerospace multi satellite launch. This is the first launch for China's new generation of carrier rockets, and China Aerospace Science and Technology Corporation Development of LOX / kerosene rocket engine for the first time mission, marking the China engine technology development has entered a new era. Hypertension in the long march rocket number six LOX / kerosene fill combustion engine parts made of climbing the long development of new materials, for the successful launch of a rocket made a contribution. To this end, the China Aerospace Science and Technology Corporation to climb long congratulatory message thank.
Climbing a long special as Pangang's only special steel enterprise, national key special steel R & D and production base, national key industry supporting enterprises and Sichuan Province large-scale backbone enterprises. After 50 years of construction and development, the formation of the "special steel production process optimization, special equipment, strong research and development strength, product technology content high" operating characteristics, covering a wide range of products, complete supporting facilities, strong research and development strength, with a number of production technology patents, a number of proprietary technology, satellite equipment steel, resistant to hydrogen embrittlement HR series steel, aircraft turbojet engine with steel fill the domestic blank, has designed and produced a new material with more than 50 brands, more than 300 varieties of different specifications, for China's aerospace, ordnance industry, nuclear industry provides nearly 600 engineering and national defense materials.
China Aerospace Science and Technology Corporation said, hope in future engine development process, continue and Panzhihua long cooperation, common for China's aerospace industry to make new contributions.
