Recently, after hours of busy work, national nuclear CAP1400 project 2#unit high-pressure welding rotor was successfully forged on 120MN hydraulic press of Erzhong Equipment, which effectively ensured the development progress of National Nuclear Demonstration Project.  

The rotor forging was manufactured for the first time in China with a high degree of difficulty in manufacturing and a great number of guidelines in process control.

In order to produce superior rotor forgings, the casting and forging plant of Erzhong Equipment ensured the process disclosure to the primary-level workers and made preliminary production plan amid its efforts in pursing both quality and progress. The furnace heating the steel ingots, the setup of sizing block and the inspection of equipment were all prepared in advance. Every effort was made to upgrade the organization model, forge 160MN and 120MN in turn, and specialized workers were put in place for technical service.

Through keeping risks under control in the operation, quantifying operation requirements and stepping up specified measures, the casting and forging plant ensured the success of the forging of the rotor by addressing all sorts of difficulties in the manufacturing process of blank.
