2012年3月31日上午,我国首台400 MN(4万吨)重型航空模锻液压机在西安阎良国家航空高技术产业基地热试成功,顺利锻造出其首个大型盘类件产品。这是我国向实现大型航空模锻件自主研制迈出的重要而坚实的一步。400 MN重型航空模锻液压机由西安三角航空科技有限责任公司承制,清华大学设计,中国二十二冶制造,是世界上最大的单缸模锻液压机。该项目以生产大型精密航空模锻件为主要目标,投产
On the morning of March 31, 2012, China’s first 400 MN (40,000 t) heavy-duty aero-forging hydraulic press was successfully tested in Xi’an Yanliang National Aviation High-tech Industrial Base, successfully forging out its first large-sized disc and plate products. This is an important and solid step taken by our country toward the independent development of large-scale aviation forgings. 400 MN Heavy Duty Air Forging Hydraulic Press is made by Xi’an Triangle Aviation Science and Technology Co., Ltd., designed by Tsinghua University and manufactured by China 22nd Metallurgical Corp. It is the largest single-cylinder forging hydraulic press in the world. The project to produce large precision air forging pieces as the main goal, put into operation
