Abstract： Aiming at the problems of much casting defects， low rate of qualified products，existed in casting the plant carrier by ordinary sand，iron - coated sand casting method was used for the production of carrier castings. The solidification simulation analysis with hot section，shrinkage carity， shrinkage porosity was carried，optimization of the casting process was realized. The solidification simulation technology was applied to guide the casting process design，and the design cycle process was shortened，the mold repair rate was reduced. Production practice results show that，by the iron-type coated sand casting method，the casting surface of planet carrier is smooth，its size is accurate，internal organization is dense，it doesn't have shrinkage carty，shrinkage porosity defects. It can realize the non-riser casting，reduce production costs，and it has significant economic benefits and competitive advantage.
