Abstract

PURPOSE:To easily produce a frozen mold having high strength by mixing a suitable amount of water and specific additives into molding sand, molding the sand and freezing the molding. CONSTITUTION:As additives, those consisting essentially of magnesium compounds, for example, magnesium silicate, magnesium oxide, etc., those consisting essentially of calcium compounds, for example, calcium hydroxide, calcium carbonate, etc., those consisting essentially of aluminum compounds, for example, aluminum oxide, aluminum hydroxide, etc., those consisting essentially of iron compounds, for example, ferrous hydroxide, ferric hydroxide, etc., and mixtures of these compounds are used. These compound particles fill the spaces between sand and sand, increase the contact area between the sand and water and increase strength, particularly deffective strength and tensile strength.
