摘要：
The article studies the method which hydroturbine part is manufactured by lost foam casting for obtaining higher quality product. The lost model material is polystyrene foam plastics, the EPS diameters are selected in 0.5-0.76mm, the casting raw material is lower carbon martensite stainless steel (ZG06Cr13Ni4Mo). The style of open pouring system is adopted, ΣFin-gate: ΣFcross-gate: ΣFdown-sprue=1: 1.1: 1.2, fireproof coating is mixed and coated, square sand box is used. The pouring temperature of liquid is 1600-1650°C. If the technology is strictly according to the design...
