摘　　要：采用数值模拟与工艺试验相结合的方法研究了熔模铸造ZL101A铸件凝固过程中不同的型壳预热温度和型壳厚度对金属温度变化的影响。数值模拟结果表明,在合金固相线温度以上,型壳预热温度对金属凝固过程温度变化的影响较大,型壳预热温度越高,金属温度波动幅度越明显;在合金固相线温度以下,型壳厚度对金属凝固过程温度变化的影响较大,且随型壳厚度的增加影响逐渐减弱。选取型壳厚度6 mm、型壳预热温度350℃进行工艺试验,验证了数值模拟的可行性与准确性。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.
