锥形冒口在球铁件上的应用

Application of Tapered Feeder in Production of Ductile Iron Castings

介绍了球铁件锥形冒口的原理和设计方法。试验表明,锥形冒口比普通冒口更有效地消除铸件缩松缺陷,并提高金属补缩率。

The principle and design of tapered feeder for ductile iron castings were introduced. Experiments have shown that this type of feeder can more efficiently eliminate shrinkage defects of castings camparing with normal feeders, and as a result, it has a higher feed metal efficiency.
