The wet moisture of the molding sand used for the sand type is slightly higher than that of the wet sand. After the sand mold is prepared, the surface of the cavity should be coated with refractory paint, and then dried in an oven. After it is cooled, it can be combined and poured. It takes a long time to dry the clay sand type, which consumes a large amount of fuel, and the sand type is easily deformed during the drying process, which affects the accuracy of the casting. Clay dry sand types are commonly used in the manufacture of steel castings and larger cast iron parts. Since the chemical hardening sand has been widely used, the dry sand type has been eliminated.
