Application of Cast Simulation for Large-Sized Iron Castings

摘要

Cast simulation using computer is useful for designing cast technology of complicated iron castings, and analyses of fluid and solidification are carried out in routine work for reference. Using the function of solidification analysis, methods differing from common ones were established in this study. Prediction and optimization of shake-out timing for large-sized iron castings, prediction of temperature distribution in casting during heat treatment process, and prediction of residual stress in casting using simple models, were carried out. The results proved that these analyses are useful in iron casting production.
