Abstract

An improved molten metal furnace including an enlarged buffer plate of nickel based superalloy material which seals and separates the furnace burners from the product to be heated. The seal from the buffer plate provides for the creation of a generally inert atmosphere for the bath of molten metal. Additionally, angling the interconnecting passageways between the furnace regions improve the thermal efficiency of the circulating molten metal.
