Beijing, June 7th The chief designer of the China Aviation Research Institute and the academician of the two academies, Gu Yufen, have emphasized that without the 800MN large die forging press, it will be impossible for China's large aircraft to achieve independent manufacturing.
In April 2013, the 800MN large die forging press was officially put into trial production, which wrote a great deal for the development of China's equipment manufacturing industry.
The ability of the die forging press determines the performance of the die forging. The performance of the large die forging determines the reliability and advancement of the product. For a long time, only the United States, Russia, and France have large-scale die forging presses of 400 MN or higher. Some key large-scale die forgings in China have to rely on imports, which are not only expensive, but also “subject to peopleâ€, which also seriously restricts the development of top equipment and industry in the fields of aerospace, petroleum, chemical, and shipbuilding.
China Second Heavy Machinery Group Co., Ltd., through the support of major special projects, has teamed up with more than 10 key universities and top research institutes in China to break through the difficulties in the development of large-scale die forging presses one by one.
On April 1, 2012, the world's largest 800MN large die forging press was successfully tested in China's double heat load test.
"A very long period of time, many of our large aviation forgings can't be done, and it's also a 'fat big ear', very thick and not refined. But these titanium alloy products that are now out are very delicate." China Academician Cao Chunxiao of the Academy of Sciences witnessed the work of the 800MN large die forging press.
The 800MN large die forging press uses a powerful pressure to make the ordinary metal materials flow in the mold, refine the internal grains, improve the rigidity and shape, and realize the overall precision forming of the large die forgings, which becomes the skeleton of the aircraft. "-- frame beam; 蜕 becomes the "spiral" of the engine - the turbine disk; 蜕 becomes the "blood vessel" of the oil field - the oil pipe tee and so on.
Up to now, China Duzhong has carried out trial production of 34 types of different types of aircraft engine turbine disks, landing gear and marine gas turbine turbine disks on the 800MN large forging press. After testing with third parties, the technical indicators of the press are better than the original design indicators, the system is stable, the action is controllable, and the molding process is in place.
The 800MN large-scale forging press has been completed and put into production, filling the gap between China's related manufacturing and equipment. It is not only a platform for independent protection, but also an equipment manufacturing platform, and also a research and development platform for new materials and new processes.
At present, China Double has applied the covering technology mastered in the forging of 800MN large die forging press to the forging of nuclear power plant head, and will gradually expand and deepen the application in related fields.
