Title (EN) NOZZLE FOR CONTINUOUS CASTING OF STEEL
(FR) AJUTAGE POUR COULAGE CONTINU D'ACIER
Abstract:
(EN) A nozzle for continuous casting of steel which excels in resistances to both clogging and melting loss, characterized in that the inner hole and/or the part in contact with molten steel of the nozzle for continuous casting of steel are formed of a refractory material consisting of spinel or spinel and periclase as mineral phase.
(FR) Ajutage servant à effectuer le coulage continu d'acier et permettant d'empêcher à la fois l'obturation et la perte de fusion, caractérisé par le fait que, soit l'orifice interne, soit la partie de cet ajutage en contact avec l'acier en fusion, sont constitués par un matériau réfractaire de spinelle ou de spinelle et de périclase en tant que phase minérale.
