A CONTINUOUS CASTING NOZZLE FOR MOLTEN STEEL

摘要

A continuous casting nozzle for casting molten steel, wherein at least a surface layer of an inner bore of the continuous casting nozzle contacting with a molten steel is formed of a refractory comprising: an aggregate consisting essentially of alumina (Al2O3) or an aggregate comprising alumina (Al2O3) as its main ingredient and melting point thereof being at least 1800 degree centigrade: from 15 to 60 wt.% and roseki as a balance. The refractory is added thermosetting resin as binder, kneaded, formed, and sintered in an anti-oxidizing atmosphere.
