| 摘要 |
The invention refers to a refractory nozzle for arrangement in the wall of metallurgic vessels, especially for steel meltings, comprising a passage opening having an upper and a bottom end, an inside wall of a solid electrolyte material enclosing the sides of the passage opening, with at least one electrode having connecting lines arranged electroconductively at the outer side of the solid electrolyte material facing away from the passage opening, and with thermal insulating material enclosing at least partially the outside of the solid electrolyte material and the electrode, and is characterized in that the at least one electrode is essentially made of a metal which has a melting point of at least 1400 °C and/or of at least one of its oxides.
