Abstract
A multi-purpose pyrometallurgical process enhancing device for metallurgical furnaces can be employed in oxy-fuel burner mode for preheating and melting of solid charge, in an oxygen injecting lance mode for decarburization of molten metal in metallurgical furnaces, in particular in melting electric arc furnaces, plasma arc furnaces and basic oxygen furnaces, and in an injector mode for injecting solid materials; the device includes a pivotally mounted water cooled generally arcuate body which can be pivoted into and out of a furnace vessel through a small opening in the shell wall for optimal positioning of the oxy-fuel flame against solid charge, in the burner mode; or injection of oxygen vertically downwardly into the molten metal at supersonic speed, in the oxygen lance mode; in one embodiment the arcuate body can be rotated about its longitudinal axis for directing the oxy-fuel flame towards a cold spot in the furnace; the tip of the arcuate body includes a replaceable, multi-opening nozzle, mounted in a retracted position inside the tip.
