摘　　要：为了解决消失模生产球铁件时容易产生的缩松和碳渣缺陷,在工艺设计时采用辅助浇口,目的是消除铁液充型造成温度较低铁液在铸件的重要部位汇集以及对易缩松部位进行有效补缩,从而消除消失模球铁件顶部出现的缩松、碳渣等缺陷。并以实例阐述了了辅助浇口在消失模球铁生产中的应用。In order to eliminate shrinkage and carbon slag defects in ductile iron production by lost foam casting, auxiliary gate is applied aiming to eliminate cold liquid iron accumulating in the important location and to effectively feed the casting part which easy to have shrinkage defects. Results show that the shrinkage porosity and carbon slag defects are eliminated with using auxiliary gate.
