ABSTRACT:
A method and apparatus for pouring molten metal in a neutral atmosphere into an ingot mold, a trumpet funnel for bottom poured ingots or a tundish box for a continuous caster or like vessel is disclosed wherein the receiving vessel is closed about a ceramic sleeve through which the molten metal is poured and wherein the normal atmosphere is replaced by vaporized hexamethylene or cyclohexane as it is sometimes called. The closure about the ceramic sleeve through which the molten metal is introduced into the receiving vessel is positioned on top of the receiving vessel and supports the ceramic sleeve and is provided with break lines or scores that permit the edge portions of the sheet-like closure to be moved in hinged relation thereto when the sheet-like closure is pushed downwardly into the receiving vessel to a point on or near the surface of the molten metal.
