铸造凝固仿真软件选型与工作流

ProCAST / MAGMA 数值仿真可在开模前预测缩孔缩松与卷气位置，工作流为：STL 建模 → 网格划分（铸件+铸型+冷铁）→ 热物性参数赋值 → 凝固求解 → 孤立液区与 Niyama 判据分析。铜合金导热强，网格尺寸建议 ≤ 最小壁厚 1/3，铜液固相线区间窄，重点关注浇后 0–90 s 的温度场。仿真缩孔位置与实际 X 光探伤吻合率可达 80% 以上，改浇口比试错法省 2–3 轮开模费。
ProCAST/MAGMA simulation predicts shrinkage and gas defects before tooling: import STL, mesh casting plus mold plus chills, assign thermo-physical data, solve solidification, then review isolated liquid zones and the Niyama criterion. Copper alloys conduct heat strongly, so keep mesh size under one third of the thinnest wall and watch the first 90 s after pouring. Predicted shrinkage matches radiography at 80%+ and saves 2–3 tooling iterations versus trial and error. ---
