Research on Changing Regularity of Green Sand Properties

摘要：

The research represents the actual effect of clay and core sand content on the permeability, compressive strength and hot wet tensile strength of green sand by adding clay and core sand into green sand mixture in order to simulate the actual situation of clay and core sand continuously increasing in the used sand during the foundry production. It was found that the content of clay and core sand affect the permeability, compressive strength and hot wet tensile strength of molding sand. With the content of clau and core sand increasing, the permeability of molding sand reduces and has a peak when core sand reaches certain content; the strength of molding sand is high and stable when the content of clay and core sand is below certain amount, and then decreases with the content of clay and core sand increasing. For green sand with resin bonded sand, the effect of clay on hot wet tensile strength appears a curve of Peak shape, while for green sand with sodium silicate bonded sand, the effect of clay and core sand on hot wet tensile strength appears Annual Ring shape as whose center is the coordinates dot.
