摘　　要：分析不同的AFS平均细度、树脂加入量对呋喃树脂砂的砂型性能影响,建立起AFS平均细度、树脂加入量与砂型性能之间的关系曲线,确定出呋喃树脂砂的AFS平均细度和树脂加入量的最佳值。试验研究发现,呋喃树脂砂的AFS平均细度控制在34~42、树脂加入量控制在0.8%~1.0%、固化剂加入量占树脂的40%、砂型抗压强度控制在2.5~4.0MPa,可以得到最优的型砂性能,从而生产出高品质的中小铸铁件。Analyze the impact of different AFS average fineness and resin addition on the sand mold performance of furan resin sand,establish a relationship curve between AFS average fineness,resin addition and sand mold performance,and determine the optimal value of AFS average fineness and resin addition of furan resin sand.Experimental research has found that the average AFS fineness of furan resin sand is controlled in the range of 34~42,the resin addition is controlled in the range of 0.8%~1.0%,the curing agent addition accounts for 40%of the resin,and the compressive strength of the sand mold is controlled in the range of 2.5~4.0 MPa,which can achieve the optimal molding sand performance and produce high-quality small and medium-sized iron castings.
