Successful forging of high-temperature alloy die forgings for domestic engines
Time:2024-09-18
On August 1, high-temperature alloy die forgings for domestic engines and super-large aircraft structural parts were successfully forged at Xi'an Aviation Base.
On August 1, high-temperature alloy die forgings for domestic engines and super-large aircraft structural parts were successfully forged at Xi'an Aviation Base. This indicates that the 400MN die forging hydraulic press production line fully meets the requirements of independent development of large die forgings, and will further enhance the innovation level and manufacturing capacity of large die forgings in China.
It is understood that the 400MN heavy-duty aviation die forging hydraulic press is manufactured by Xi'an Triangle Aviation Technology Co., Ltd., designed by Tsinghua University, and manufactured by China 22nd Metallurgical Co., Ltd., and is the world's largest single-cylinder die forging hydraulic press. The main goal of this project is to produce large-scale precision aviation die forgings. After it is put into production, it will greatly improve the development and production level of my country's aviation die forgings, and promote the development of my country's aircraft and aero-engine technology. It is of great significance to promote the rapid development of my country's aviation industry.
On the morning of March 31, 2012, the hot test of 400MN large die forging hydraulic press was successful, and large plate products were successfully forged. However, the GH4698 superalloy die forgings forged this time have a diameter of 1020mm and an area of more than 1 square meter for TC18 aircraft structural parts. Both superalloy and titanium alloy die forgings have adopted advanced forging technology, and the products are fully formed and the dimensions fully meet the requirements of technical drawings. It represents the current technical level of the domestic aviation forging industry and marks the official entry of Xi'an Delta Aviation Technology Co., Ltd. into the world aviation forging field.
