摘要：An improved vertical furnace for melting metal pieces, such as pieces of copper cathode. The furnace has a generally round interior wall of refractory brick material which enclos a vertical melting chamber having a plurality of burner openings through the refractory wall. Heat, being injected through the openings by means of a novel burner design, melts the metal pieces under metallurgically controlled conditions. The burners are arranged near the bottom floor of the melting chamber which is sloped toward a single outlet thus allowing the molten metal to continuously drain from the melting chamber. The burners are fed a mixture of fuel and air from a plurality of remote mixing stations so as to reduce turbulence at the burners thereby significantly reducing the operating noi level and refractory wear compared to prior art furnaces. A combustion chamber between the burner and the melting chamber is provided so as to prevent entry of uncombusted fuel and/or air, thereby maintaining the cloly controlled atmosphere in the melting chamber.
