摘要
利用ProCAST-CAFE模块,对42CrMo环件的凝固组织进行了模拟,研究了浇注温度对凝固组织的影响。结果表明,随着浇注温度的增加,晶粒尺寸增大,晶粒个数减少。同时得出在1510℃,晶粒度最好;当浇注温度达到1550℃时,晶粒开始粗化。
Solidification structure of 42CrMo ring was simulated with CAFE module of ProCAST software. The effect of casting temperature on solidification structure was studied. Results show that with the casting temperature increasing the grain size grows up and the number of grains reduces. The grain degree is best at 1510℃, and when casting temperature reaches 1550℃, the grains begin coarsening.
