实型铸造法的关键基础技术包括:模样的材料及成形、涂料、型砂的振动充填、金属液的充填。国内外的研究和经验表明,使用铸造低密度EPS珠粒模样;用具有高的强度、良好的涂挂性和触变性、高的透气性的涂料;干砂的填充密度高,各向压力一致;金属液的充填平稳快速。是实型铸造法获得成功的关键。 The key foundational techniques of solid casting include: the appearance of materials and forming, the filling of coatings, the filling of sand and the filling of molten metal. Domestic and foreign research and experience show that the use of cast low density EPS beads look like; with high strength, good coating and thixotropy, high permeability of the paint; dry sand packing density is high, the same pressure in all directions Filling of metal liquid is steady and fast. Is the real casting method to obtain the key to success.
