Abstract

A forged copper burner enclosure capable of being mounted within the side wall of a steel melting furnace for the purpose of providing an improved cooling characteristic to a burner lance. The burner enclosure is provided with a central passage adapted to receive a burner lance for injecting oxygen into the batch of molten metal of an electric arc furnace. The forged burner enclosure is positioned such that only a solid forged copper face is on the furnace side when installed. The burner enclosure has an optional through hole which can be used for the purpose of treating the metal melt with particulate supply ranging from slag forming materials to metallurgical materials. The burner enclosure further has a number of coolant holes and tubes which provide a unique bidirectional flow of cooling fluid through each hole and increases cooling fluid velocity while reducing stalling and hot spots of the cooling fluid thereby providing better heat transfer and physical characteristics over cast or weld-assembled burner enclosures.
