Abstract (en)
[origin: US2003011112A1] A refractory nozzle is provided for arrangement in the wall of metallurgic vessels, especially for steel melts. The nozzle has a passage opening with an upper end and a bottom end, an inside wall of a solid electrolyte material enclosing the passage opening. At least one electrode is arranged on an outer side of the solid electrolyte material facing away from the passage opening and having connecting lines leading electro-conductively therefrom. Thermal insulating material at least partially encloses the outer side of the solid electrolyte material and the electrode. The at least one electrode is essentially made of a metal which has a melting point of at least about 1400° C. and/or of at least one of its oxides.
