On August 2, CRCC Heavy Equipment Base was completed and put into operation in Xiangyang, Hubei Province. The picture shows a 900 ton beam carrier in production. On July 28, the cold leg bend of the main pipe of Unit 1 of Sanmen Nuclear Power Station, the world's first third-generation AP1000 nuclear power plant, completed the bending forming process in the hydraulic locomotive workshop of China Erzhong Forging Branch, marking that Erzhong has mastered the most difficult bending forming core technology in the manufacturing process of the cold leg bend of AP1000.
In recent years, the production of large forgings in China has made great progress, reaching a certain scale and level of production, but the process, equipment and management still cannot meet the needs of the market. The Chinese die forging industry is still dominated by old-fashioned forging hammers and double disk friction presses, which still has a large gap compared with the developed countries in the world. It is far from meeting the needs of the domestic and foreign forging markets, and it is in urgent need of transformation and improvement. So far, only about 150 hot die forging press production lines have been built, and hot precision forging, warm forging and cold forging production processes have been developed.
Today, the 2021 Changsha International Construction Machinery Exhibition, a grand event in the construction machinery industry that has attracted worldwide attention, has been launched. The 2020 Changsha International Construction Machinery Aftermarket Trade Conference (hereinafter referred to as "Aftermarket Trade Conference"), one of the supporting activities, also opened at the Changsha International Exhibition Center.
