FEM numerical simulation is carried out for 30Cr2Ni4MoV steel low-pressure rotor based on a typical quenching heating process. Some influencing factors on the temperature difference between surface and center of rotor, phase transformation and stress distribution is studied. The factors contain heating time and middle temperature during the first stage, as well heating and holding time during the second heating stage. It provides fundamental information for the further process optimization.
