摘要： A refractory nozzle is provided for arrangement in or on a wall of a metallurgical crucible, particularly for steel melts, having a discharge duct surrounding a flow passage, wherein the discharge duct has a surface delimiting the flow passage and an outer housing. In order to improve the known solutions of the prior art, one embodiment of the nozzle is characterized by the discharge duct having an upper part and a lower part with the lower part being fixed in or on the upper part, wherein the surface of the upper part delimiting the flow passage is made of a different material than the surface of the lower part delimiting the flow passage. In a second embodiment the nozzle is characterized by the discharge duct having an upper part and a lower part with the lower part being fixed on or in the upper part, wherein the diameter of the flow passage in the upper part is greater than the diameter in the lower part.

摘要： 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 1400null C. and/or of at least one of its oxides.

摘要： A refractory nozzle is provided for a metallurgical vessel, in particular for steel melts, wherein the nozzle has a flow-through opening with an upper end, a lower end, and an inner wall laterally enclosing the flow-through opening. In order to improve known discharge nozzles, in particular with regard to their thermal shock resistance, a heater and/or a thermal insulating material, that dissolves or bums upon contact with fluid steel, is arranged along the inner wall in the flow-through opening.
摘要翻译：为冶金容器提供耐火喷嘴，特别是用于钢熔体，其中喷嘴具有一个具有上端，下端和横向封闭流通开口的内壁的流通开口。为了改进已知的排出喷嘴，特别是关于它们的耐热冲击性，在流通开口内的内壁上布置有与流体钢接触时溶解或燃烧的加热器和/或绝热材料。
