Abstract

According to the orthogonal experimental method, the influences of the feeding sequence, premixing time and final mixing time on the permeability, green compressive strength, green splitting strength and shatter index are studied when the interactions of the factors are considered. The results show that the final mixing time is the most important factor that affects these property parameters of green sand. Besides the interaction between the feeding sequence and final mixing time has bigger influence on shatter index than the feeding sequence, the influence of factor interactions on permeability, green compressive and splitting strengths is lower than that of single process parameter. Comprehensively considering these four property parameters, the optimal mixing process can be obtained, namely, the quartz sand and water are first added and premixed about 4 minutes, and then the clay and coal are added and mixed about 12 minutes.
