研制了铸钢件凝固过程数值模拟中进行识别多个熔池的技术 ,利用此技术可将铸钢件凝固过程中所形成的多个相互孤立的熔池一一区分开 ;在此基础上 ,能够更加准确地预测由各个孤立的熔池所形成的缩孔 ,依此提高了铸钢件凝固过程数值模拟中对缩孔位置和形状预测的准确度 The technology of identifying multiple puddles in the numerical simulation of the solidification process of steel castings was developed. By using this technique, a number of isolated puddles formed during the solidification of the steel castings can be distinguished one by one. On this basis, Can predict more accurately the shrinkage cavity formed by each isolated molten pool, thereby improving the accuracy of predicting the position and the shape of the shrinkage cavity in the numerical simulation of the solidification process of the cast steel
