Simulation optimization of Air-cooling temperature field for Ring-shaped forging parts
Heat treatment is the key to determine the final microstructure and properties of the metal,and the temperature field control of the cooling process is the core of heat treatment.Large ring-shaped forging parts have large size,poor temperature field consistency and difficult controllability under air-cooled heat treatment conditions.In view of the above problems,this paper inversely calculates the convective heat transfer coefficient through the air-cooled normalizing experiment and measurement of the scaled ring-shaped parts.Through the simulation of the air-cooled heat dissipation of the ring-shaped parts,the evolution of the air-cooled temperature field of the ring-shaped parts is studied,and the optimization suggestions of the air-cooled process are given.The results show that the flow field and temperature field are coupled during the air-cooled normalizing process.The reasonable design of the deflector and the wind speed can improve the flow field distribution and significantly improve the heat dissipation efficiency of ring-shaped parts.The method in this paper can provide technical support for temperature field analysis and heat treatment process optimization of large ring forging parts during air cooling normalizing process.
