Beschreibung
Zusammenfassung:	A container for molten metal has at least one opening in which a refractory nozzle brick is mounted. A refractory purge plug or a refractory sleeve defining an outlet opening is inserted in the nozzle brick opening. A defined gap is formed between the nozzle brick opening and the purge plug or the sleeve and is filled with a refractory mass, this mass consisting of a material which can be easily bored or milled out of the mass for the purpose of replacing the purge plug or the sleeve. In this manner, laborious cleaning steps can be avoided and the nozzle brick no longer risks being damaged.
