摘要： Refractory casting nozzle for a changing device arranged at the outlet of a metallurgical vessel is provided with a top side refractory plate, which is provided with an abutting surface at each of two opposing end faces. During a change, the casting nozzle can either be moved against the one abutting surface of a top side plate of an adjacent casting nozzle or be pushed out from this casting nozzle. This top side plate is provided, in the one abutting surface, with a centering element protruding on both sides of this and in the opposite abutting surface with a bevelling on both sides, designed such that, during a change, the casting nozzle cooperates, with its centering elements with the bevellings of the adjacent identically designed casting nozzle, thus bringing about a guiding of the two casting nozzles.
