摘要
采用ProCAST软件对ZG13Cr9Mo2Co1NiVNbNB铸钢件进行了铸造过程数值模拟研究和缩孔缩松预测,通过解剖试验得到冒口内实际缩孔缩松分布。研究了不同模拟参数对冒口内缩孔缩松预测精度的影响,得到预测的缩孔缩松与实测结果较为吻合的最优计算参数。
ProCAST software was used to simulate the casting process of ZG13 Cr9 Mo2 Co1 NiVNbNB steel castings and predict the shrinkage defects.The shrinkage defects in riser zone was first measured by dissection way,and then simulated by using different process parameters to obtain optimal simulation parameters.The impact of simulation parameters on the prediction accuracy of shrinkage and dispersed shrinkage in riser zone was studied.The results show that the predicted shrinkage defects results are more close to the actual measured ones.
