Title (EN) TAPHOLE ASSEMBLY
(FR) ENSEMBLE TROU DE COULÉE
Abstract:
(EN) A taphole assembly for a metallurgical vessel, made of at least two ring shaped bricks ( 1,2.3,4), made of an MgO based refractory material and arranged one after the other, to form a continuous tapping channel (C), wherein a terminal brick (4) at a lower end of the taphole assembly, when the metallurgical vessel is in a tapping position, i s a multi- layer brick, comprising an outer layer (4o) made of a material which has a thermal conductivity of at most 80 % of the thermal conductivity of an MgO based inner layer (4i) of said terminal brick (4),
(FR) L'invention concerne un ensemble trou de coulée pour une cuve métallurgique, constitué d'au moins deux briques de forme annulaire (1, 2, 3, 4), constituées d'un matériau réfractaire à base de MgO et disposées les unes après les autres, pour former un canal de coulée continu (C), une brique terminale (4) au niveau d'une extrémité inférieure de l'ensemble trou de coulée, lorsque la cuve métallurgique est dans une position de piquage, étant une brique multicouche, comprenant une couche externe (4o) constituée d'un matériau qui a une conductivité thermique d'au maximum 80 % de la conductivité thermique d'une couche interne à base de MgO (4i) de ladite brique terminale (4).
