PROBLEM TO BE SOLVED: To provide a refractory nozzle which is very reliable, stable and low in costs. SOLUTION: The refractory nozzle for arrangement in the wall of a metallurgical vessel, particularly, for steel melts, is composed of a passage opening (1) having the upper end part and the bottom end part, an inner side wall (2) made of a solid electrolyte material enclosing the side parts of the passage way opening (1), at least one of electrodes (3, 4) having connecting wires (5) electro-conductively arranged at the side part of the outside of the solid electrolyte material facing away side from the passage opening (1) and a thermally insulating material at least partially enclosing the outside of the solid electrolyte material and the electrodes (3, 4). At least one of the electrodes (3, 4) is composed of a metal having the melting point of at least 1,400 deg.C and/or substantially composed of oxide thereof.
