Abstract

Process for inhibiting the erosion of the surface of molds for casting, whose erosion normally occurs during the contact of said surface with molten molten metal, while subsequently preventing adhesion of said ingots to the basic member of the mold after formation of the molds. same, characterized in that a suspension is applied to said surface that includes a refractory material suspended in a binder, said suspension being applied in an amount sufficient to form a coating of sufficient thickness to inhibit said erosion and prevent said adhesion, allowing such suspension will dry, whereby a protective solid coating is formed on said basic member, said suspension comprising at least one refractory material selected from the group consisting of vitreous silica, crystalline silica, alumino silicate, alumina, graphite, zirconium silicate , magnesium silicate and arcill a, suspended in a binder comprising a colloidal silica sol and a silicic acid sol, said binder being present in an amount sufficient to bind together the refractory particles and thus form a firmly adherent coating that joins said surface.
