Abstract

La présente invention concerne une paire de plaques réfractaires (11, 12) disposée dans un récipient unitaire. De nombreux tubes longs en céramique (14) sont disposés entre la paire de plaques réfractaires (11, 12). Une extrémité (14a), du côté de l’ouverture de sortie de matière en fusion (9), de chaque tube en céramique (14) est fixée à la plaque réfractaire (12) à l’aide d’un ciment réfractaire (22), et l’autre extrémité (14b) de chaque tube en céramique (14) est fixée à la plaque réfractaire (11) à l’aide d’un mortier fibreux (21). Ceci permet de conserver la résistance au choc thermique tout en renforçant la résistance de fixation des tubes en céramique (14).
