A discharge structure includes a refractory plate, a mounting frame supporting the refractory plate, an exchangeable refractory nozzle, a mounting sleeve surrounding and supporting the nozzle, a lock between the sleeve and frame for locking the sleeve and the nozzle to the frame in a position with an inner end face of the nozzle urged toward a confronting surface of the refractory plate, and a refractory joint forming a seal between the end face and surface. An abutment extends from the frame and abuts an inner end of the nozzle, thus forming an axial support for the nozzle upon the lock urging the nozzle toward the plate, thus ensuring spacing between the end face and the surface by a predetermined distance and the resultant formation of the joint at a predetermined thickness.
