摘要：Ice-pattern investment casting is a new kind of casting process. One of its key technologies is to choose molding materials which can apply to frozen temperature. This paper studied some behaviors of molding material in ice-pattern investment casting. Different ethyl silicate binder, refractory materials and catalyst were chosen and the experiments were carried out in the freezing temperature. The optimized process and the composition of binder and catalyst for ice-pattern investment casting was determined by comparing the room temperature strength and high temperature strength of refractory shell. The experiment is helpful to promote the application of the casting process.
