基 于 有 限 元 模 拟 的 高 锰 钢 衬 板 消 失 模 铸 造 工 艺 评 估

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.
