Abstract: Physical simulation and numerial analysis are used to solve the problems to the forming process or 600MW steam turbine low-voltage rotor as a whole, suck as the forging programme, technical parameters, forging quality and the reliability of the process. The scientific basis for optimizing the forming process and controlling the quality of the rotor is provided.
Key words: Heavy forging  Rotor  Simulation test
