ABSTRACT:
A corner wedging consumable hot top for ingot molds is formed of four side board sections and four corner wedges made of a combustible consumable material capable of being wedged in opposed relation within an ingot mold so that the hot top formed thereby conforms with the cavity shape in the ingot mold and when ignited by the molten metal poured therein supplies heat to maintain a pool of molten metal as necessary for filling cracks and pipes in the cooling ingot.
