摘　　要：利用ProCAST有限元模拟分析软件,对中空侧壁保温45 t钢锭定向凝固过程温度场进行了计算机模拟。结果表明:应用中空侧壁保温技术,顶面覆盖发热剂,辅以改进后的水冷Cu铸锭底盘,能够促进钢锭的定向凝固。The temperature field in 45 t steel ingot with hollow lateral wall insulation during unidirectional solidification was simulated with finite element analysis software ProCAST. The results show that using lateral wall insulation technology, heating agent on the top surface and an improved auxiliary water-cooled Cu stool can optimize unidirectional solidification process.
