The Numerical Value Simulation Research for the Large Forgings during the Heat Treatment Process

Based on the analyzing of the heat transfer process of the large forgings, we have established a temperature distribution model ,and performed the simulative calculation for the variable regularity of the temperature field on the large forgings. Meanwhile contrastive analysis between the simulated results and the experimental results have been performed as well, in this case the simulative calculation for the quenching process of a rotor made of 26Cr2Ni4MoV has been also performed, which shows the correctness and advantage of the numerical value simulation to the heat treatment process, and shall be the basis for the further research of the structure transformation and stress deformation to the large forgings in the future.
