摘　　要：通过采用不同的混砂工艺方案,随着混砂时间的改变,研究了混砂工艺对型砂性能的影响;同时,采用不同的芯砂加入方案,随着加入量的改变,研究了芯砂对型砂性能的影响。结果表明,型砂各种性能均随混砂工艺和混砂时间的不同而变化,也会随着芯砂加入工艺和加入量的不同而改变。为最终确定和选用混砂工艺和芯砂的加入量提供了指导依据。The influence of sand mixing process on the properties of molding sand was studied with the change of sand mixing time by adopting different sand mixing process schemes;At the same time,the influence of core sand on the properties of molding sand was studied with the change of the amount of core sand by using different core sand adding schemes.The results show that the properties of molding sand vary with the mixing process and time,and also with the addition process and amount of core sand.It provides a guiding basis for the final determination and selection of sand mixing technology and the amount of core sand.
