摘　　要：本文介绍了该厂GF气冲造型线的型砂要求、生产实际中控制情况和应用效果。This paper introduces in detail the experience of moulding sand quality Control on GF air impacting mould line. It Points out that magnetic separation, crumbling and screening, stirring with water adding. cooling, aetating and uniform new sand adding are essential links for the sand preparation of GF line; And purity. grain size and temperature are the basical control factors. It concludes that the optimum sand characteristies for GF air impcting moulding line as following: compactibility 30～40％. green strength O.18～0.22MPa, moisture 3.8～4.6％ (or 4.2～5.2％).
