Effect of Shell Parameters on Temperature Change During Solidification Process of ZL101A Alloy
The effects of different shell preheating temperature and shell thickness on the metal temperature change during the solidification process of investment casting ZL101A castings were studied by combining numerical simulation and process test.The numerical simulation results show that above the solidus temperature of the alloy,the preheating temperature of the shell has a greater influence on the temperature change of the metal solidification process,and the higher the preheating temperature of the shell,the more obvious the fluctuation range of the metal temperature.Below the solidus temperature of the alloy,the influence of the shell thickness on the temperature change of the metal solidification process is greater,and the effect gradually weakens with the increase of the shell thickness.The process test was carried out with a shell thickness of 6 mm and a shell preheating temperature of 350 ℃,which verified the feasibility and accuracy of the numerical simulation.
