Stainless steel casting parts

Stainless steel casting parts is a kind of wax mold used in the production of stainless steel products when some products are strange in shape and cannot be produced by processes such as elbows. For the production of such irregular shapes (internal hollow or solid), a wax mold is used. →Do the sand mold→liquid material filling molding process.
Advantages and disadvantages of stainless steel casting parts process:
1. Due to the poor fluidity of the molten steel, in order to prevent the cold separation and pouring of the steel castings, the wall thickness of the steel castings should not be less than 8 mm; the structure of the casting system is simple and the cross-sectional size is larger than that of cast iron; Or hot-casting type; suitable to increase the pouring temperature, generally 1520 ° ~ 1600 ° C, because the pouring temperature is high, the molten steel has a high degree of superheat, a long time to keep the liquid, and the fluidity can be improved. However, if the pouring temperature is too high, it will cause defects such as coarse crystal grains, hot cracks, pores and sand. Therefore, the casting temperature of a small, thin-walled and complex shape is generally about +150 ° C of the melting point of steel; the casting temperature of large and thick-walled castings is about 100 ° C higher than its melting point.
2. Since the shrinkage of stainless steel precision casting greatly exceeds the cast iron, in order to prevent the shrinkage and shrinkage defects of the casting, most of the casting process uses risers, cold irons and subsidies to achieve sequential solidification. In order to prevent shrinkage, shrinkage, porosity and crack defects in stainless steel castings, the wall thickness should be uniform, sharp angle and right angle structure should be avoided, sawdust should be added to the molding sand, coke can be added to the core, and hollow type should be adopted. Core and oil sand core to improve the repellent and breathability of the sand or core.
