Molten metal furnace

摘要

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.

主权项

1. An improved molten metal furnace comprising:
a molten metal reservoir adapted to retain a bath of molten metal; at least one heater proximate to said reservoir, wherein said at least one heater is surrounded by an atmosphere comprising air and heater exhaust gases; and a buffer plate disposed between said bath of molten metal and said at least one heater, wherein said buffer plate seals and separates said molten metal bath from said heater atmosphere; wherein said at least one heater generates sufficient heat to melt a metal which makes up said molten metal bath, said heat passing through said buffer plate to said molten metal bath; and wherein said buffer plate is a superalloy having an emissivity of approximately 0.96-0.98.
