摘　　要：气孔缺陷是湿型砂灰铸铁铸造最常见的缺陷之一。气孔缺陷的基本解决方法是"开流节源","开流是"通过增设、增大排气通道,增强溢流等。"节源"是减少制造原料中产生气体物质。再辅助以调整浇注系统、改善加工余量等方案叠加,可有效解决。Hole defect is one of the most common defects in wet sand gray cast iron.The basic solution to the porosity defect is"open flow saving source","open flow is"by adding or increasing the exhaust passage,enhancing the overflow and so on."Energy saving"means reducing the production of gaseous substances in manufacturing materials.The solution can be effectively solved by adjusting the gating system and improving the machining allowance.
