Abstract (en)
A submerged nozzle for continuous casting of steel wherein the whole nozzle or a part or the whole of the inner wall portion thereof which comes into contact with molten steel is made of a spinel-periclase-graphite type refractory, especially a spinel-periclase-graphite type refractory comprising 50 to 95% by weight of spinel, 0 to 20% by weight periclase, 5 to 30% by weight of graphite, and not more than 3% by weight of unavoidable impurities. The inner wall portion 1 and the portion 2 around the spout of the inner wall portion can be made of the above spinel-periclase-graphite type refractory, the nozzle main body can be made of AG-based refractory, and the powder line portion 3 can be made of ZrO2-C type refractory. <IMAGE>
