NUMERICAL SIMULATION ON HEATING PROCESSOF 9Cr2Mo COLD ROLLER

A mathematical model of heating austenitization process has been founded in this paper.The evolution of transient temperature field and austenitization in 9Cr2Mo cold roller during the heatingprocess have been simulated using FEM numerical method. The accuracy of simulation results has alsobeen tested and verified by sampling the heat curves of some positions in the cold roller. The optimumheat technology of cold roller has been proposed according to the simulation results, which has obviouslyreduced the heating time, and has remarkably effect on energy saving.
