消失模壳型铸造工艺实践

Practice of Lost Foam Shell Casting Process

介绍了一种改进的消失模铸造工艺-消失模气化、空壳负压浇注成型工艺。它解决了传统消失模铸造常见的缺陷,如表面增碳、气孔等,而且铸件表面精度高,内外在质量好。

An improved lost foam casting process was introduced, which was EPS gasification and shell casting under negative pressure. It solves the common defects of the traditional lost foam casting, such as surface carburizing, blowhole, etc, and the casting has high surface precision, good internal and external quality.
