Abstract (en)
[origin: WO2010054853A2] A container for molten metal has at least one opening (4; 24) in which a refractory nozzle brick (5; 5'; 25; 25') is mounted. A refractory purge plug (10; 10') or a refractory sleeve (30; 30') defining an outlet opening (31; 31') is inserted in the nozzle brick opening (6; 6'; 26; 26'). A defined gap is formed between the nozzle brick opening (6; 6'; 26; 26') and the purge plug (10; 10') or the sleeve (30; 30') and is filled with a refractory mass, said mass consisting of a material which can be easily bored or milled out of the mass for the purpose of replacing the purge plug (10; 10') or the sleeve (30; 30'). In this manner, laborious cleaning steps can be avoided and the nozzle brick no longer risks being damaged.
