A CONTINUOUS CASTING NOZZLE FOR CASTING MOLTEN STEEL

摘要

The invention is related to a continuous casting nozzle for casting of alumi num killed steel without clogging of the bore of the nozzle. The surface layer of the bore of the continuous casting nozzle contacting wi th the molten steel is formed of a refractory comprising graphite from 10 to 35 wt%, an aggregate of 10 to 60 wt% selected from from alumina matter, zirconia matter , zircon matter, or alumina-silica matter and roseki containing the pyrophyllite (Al2O3~4SiO2~H2O) as the main component as the rest part of the above mentio ned materials.
