The object of the present invention is to provide a nozzle for use in continuous casting of steel which simultaneously provides resistance to adhesion of Al2O3 inclusions, damage resistance, and spalling resistance. The nozzle for use in continuous casting of steel according to the present invention is characterized in that the refractory material of at least the interior surface of the nozzle and/or the portions to come into contact with molten steel is composed of amorphous silica and alumina and has a chemical composition of 5 to 40 percent by weight of SiO2, 60 to 95 percent by weight of Al2O3, and 3 percent by weight or less of unavoidable impurities. <IMAGE> |
