Abstract
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.
