Pass the project of double aluminum alloy large die forgings in China

Recently, the national machinery group China second heavy Machinery Group Co., Ltd. (hereinafter referred to as "China Erzhong") a large aluminum alloy die forging engineering development project successfully passed the process review.

Hou Xiao, academician of the Chinese Academy of Engineering, and relevant experts from the evaluation team visited the 80,000-ton die forging press, inspected the typical parts of the project, listened to the report on the leading process review of China Duozhong Wanhang Die forging Project, questioned and consulted the relevant materials, and considered that the process evaluation data provided by China Duozhong Wanhang Die forging are complete, the data are detailed, the leading process is reasonable and feasible, and it is agreed that the project forgings pass the process review.

The smooth passing of the process evaluation indicates that the basic process research and the formulation and verification of the leading process have been completed in a large-scale aluminum alloy die forging engineering development project undertaken by China heavy Wanghang Die forging, and the project has successfully entered the stable preparation stage of the engineering. it will lay a solid foundation for the development of a key type of spacecraft.
