Abstract

PURPOSE: To easily disintegrate and remove a core after casting, which bears high pressure of molten metal and does not develop breakage and penetration of the molten metal, by using sodium chloride as raw material and burning at the specific temp. after pressing and forming this raw material in a mold.
CONSTITUTION: The disintegratable core 1 uses the sodium chloride with grain size set to 60-150μm as the raw material and this raw material is burnt at 670-720°C after being pressed and formed in the mold, and shaped. Therefore, this bears the high pressure of molten metal in high pressure casting, and the penetration of molten metal and the breakage are not developed, and after casting, this is removed with good disintegration and cavity part of cooling hole, etc., in the casting can be formed as the desirable shape.
