The hydrogen-oxygen engine of the launch vehicle requires titanium alloy castings
In order to break through the technical bottleneck of ultra-low temperature mechanical properties, composition uniformity and impurity content control of titanium alloy castings for hydrogen-oxygen engines, the project team of SYZZ Alloy Technology Corporation has carried out hundreds of furnace composition optimization and performance test research, repeated tests and corrections, from thousands of The optimal composition ratio and smelting process parameters are found in the group data, which effectively improves the performance and stability of the casting.
For aerospace products, quality comes first. The ability to produce high-quality titanium alloys and high-temperature alloy castings for rocket hydrogen-oxygen engines is inseparable from the whole-process quality control of development and production.
Based on years of technological accumulation and innovation, the project team has achieved major innovations. SYZZ successfully solved the key issues of composition control, internal and external quality control, and size control of high-quality titanium alloy castings for hydrogen pump series, and developed a high-performance, high-quality ultra-low temperature resistant , High pressure titanium alloy castings.
At 12:41 on July 23, 2020, China's Long March 5 carrier rocket ignited and took off at China's Wenchang Space Launch Site, sending the "Tianwen-1" probe, China's first Mars exploration mission, into the ground fire transfer orbit.
"The more than ten kinds of titanium alloy castings used in the Long March 5 and Long March 5B carrier rockets and the two hydrogen-oxygen engines are all from SYZZ!"
Over the years, SYZZ has provided core casting product guarantee for the Long March 5 launch vehicle engine, and has successively met the requirements of the new generation of manned spacecraft test ships, the Mars probe "Tianwen-1", "Chang'e-5", "Tianhe Core Module", etc. A number of major engineering spacecraft have been launched, and excellent products have been used to escort the development of China's aerospace industry.
