摘要

介绍了消失模法生产蠕铁排气出口管的工艺过程。试验发现

采用反直浇道结合侧注的模组形式为佳

每组8件、管口朝下;涂料直接影响铸件表面积碳及皱皮倾向;并采用消失模法批量生产了蠕铁排气出口管

材料性能及金相组织达到要求

铸件壁厚均匀

表面光滑

已用于红旗轿车的部分车型。

Abstract

Vermicular graphite cast iron exhaust pipe in lost foam casting was introduced. The experiment shows that using reverse ingate combined with side-gating system is beneficial to manufacturing the pipe with every assemble set eight parts. Coating has obvious effects on the carburization and ripples of parts surface. The exhaust pipe in lost foam casting with uniform thickness and smooth surface can meet the requirements in material performance and microstructure

having been used for some type of HongQi Car.
