摘　　要：介绍了G10MnMoV6-3某铸件的产品性能要求,重点论述了利用因果图分析G10MnMoV6-3铸件气孔,确定产生的主要原因,并制定对策表,采取相应的措施,验证措施实施后的效果:特定位置粗加工后出现气孔缺陷的比例由原来的的60%减低至10%以内。This paper introduced the performance requirements of G10MnMoV6-3 casting,discussed the use of fish bone diagram emphatically to analyze blowhole of the G10MnMoV6-3 casting,determined the main causes,formulated the countermeasure table,taken the corresponding measures,verified measures after the implementation of the effect:the rate of blowhole in specific locations after rough machining reduced from 60%to less than 10%.
