摘　　要：针对消失模铸造高锰钢衬板的缩孔缩松倾向高的问题,利用ProCAST软件模拟了顶注式浇注一箱8件(A工艺)、阶梯侧注式浇注一箱10件(B工艺)和侧注式浇注一箱4件(C工艺)的衬板充型和凝固过程,并评估了3种工艺的铸造缺陷。结果表明,采用A工艺时金属液填充过程出现流动紊乱,而B工艺时充型过程更加紊乱,C工艺时充型过程相对平稳。采用A工艺和B工艺的衬板内部均出现大范围的缩孔缩松缺陷,尤其是B工艺中间6块衬板内部缺陷较为分散,且缺陷位置靠近衬板表面,而C工艺衬板内部缺陷集中于心部。综合比较,最佳的消失模铸造工艺为侧注式浇注的C工艺。For the problems of high tendency of shrinkage holes and shrinkage porosities in high manganese steel liner by lost foam casting,ProCAST software was used to simulate the liner filling and solidification process of process A with top injection casting of 8 pieces in a box,process B with step side injection casting of 10 pieces in a box and process C with side injection casting of 4 pieces in a box,and the casting defects were evaluated.The results indicate that the filling process of metal liquid with process A presents flow disturbance,while that of process B is more turbulent and that of process C is relatively smooth.Specially,the defects in the middle 6 liner plates of process B are more scattered and located close to the surface of the liner plates,while the defects in the liner plates of process C are concentrated in the core.The optimized LFC process is the process C with side injection casting.
