METHOD FOR THE PYROMETALLURIGICAL TREATMENT OF METALS, MOLTEN METALS, AND/OR SLAGS

摘要

In a method for the pyrometallurgical treatment of metals, molten metals, and/or slags in a metallurgical unit or melting crucible, in particular in an electric arc furnace, an injector device (1) is used to blow oxygen-rich gases onto or into the metals, molten metals, and/or slags. When operated as an injector, said injector device (1) accelerates the oxygen-rich gases and forms a high-speed jet with a gaseous shroud that entirely surrounds the jet. The disclosed method is characterized in that the injector device (1) is alternatively used as a burner in a burner operation.
