Abstract
La structure réfractaire se compose de deux pièces réfractaires (11, 13) maçonnées l'une dans l'autre, la première pièce (11) formant une frique réfractaire supérieure qui délimite un canal de coulée supérieur (10), ladite brique se trouvant maçonnée dans le revêtement réfractaire (6) qui tapisse le fond de la poche de coulée et la seconde pièce réfractaire (13) formant un anneau inférieur qui délimite un canal de coulée inférieur (16) prolongeant le canal de coulée supérieur (10). L'interstice entre les deux pièces réfractaires (11, 13) précitées est empli d'un joint de mortier (18) qui s'étend en formant une surface tronconique entourant une partie du canal de coulée inférieur et se prolonge jusqu'à la surface cylindrique extérieure de la bride extérieure (15) de l'anneau (13) en entourant ladite surface cylindrique extérieure jusqu'à la surface extérieure du fond (1) de la poche de coulée.The refractory structure consists of two refractory pieces (11, 13) masonry one inside the other, the first piece (11) forming an upper refractory brick which delimits an upper pouring channel (10), said brick being masonry in the refractory lining (6) which lines the bottom of the ladle and the second refractory piece (13) forming a lower ring which delimits a lower casting channel (16) extending the upper casting channel (10). The gap between the two aforementioned refractory pieces (11, 13) is filled with a mortar joint (18) which extends by forming a frustoconical surface surrounding a part of the lower pouring channel and extends to the surface outer cylindrical of the outer flange (15) of the ring (13) surrounding said outer cylindrical surface to the outer surface of the bottom (1) of the ladle.
