The invention relates to a set of refractory assemblies (8, 12, 30, 32, 42, 48, 50, 60), which is capable of being used between an upstream container (2) and a downstream container (10) of a plant for transferring liquid metal, in particular steel, comprising: a tapping spout (28) via which the metal flows from the upstream container (2) into the downstream container (10), each refractory assembly (8, 12, 30, 32, 42, 48, 50, 60) of the tapping spout (28) having at least one surface forming a mating surface (22) with a corresponding surface of an adjacent refractory assembly (8, 12, 30, 32, 42, 48, 50, 60); a flow regulator (26) for regulating the flow of liquid metal through the tapping spout (28); a shroud channel (34) placed around the tapping spout (28) near at least one mating surface (22) between refractory assemblies (8, 12, 30, 32, 42, 48, 50, 60) and having an inlet (38) capable of allowing the intake of a fluid; in which the shroud channel (34) has an outlet (40) capable of allowing the fluid to escape to the outside of the plant.
L'invention a trait à un jeu d'ensembles réfractaires (8, 12, 30, 32, 42, 48, 50, 60) pouvant être utilisés entre le conteneur amont (2) et le conteneur aval (10) d'une installation servant à transférer du métal liquide, de l'acier notamment. Ce jeu comporte un chenal de coulée de métal (28) par lequel le métal s'écoule du conteneur amont (2) vers le conteneur aval (10), chaque ensemble réfractaire (8, 12, 30, 32, 42, 48, 50, 60) du chenal de coulée de métal (28) ayant au moins une face formant une surface de contact (22) pour la face correspondante d'un ensemble réfractaire adjacent (8, 12, 30, 32, 42, 48, 50, 60). Il comporte également un régulateur de débit (26) destiné à réguler le débit de métal liquide traversant le chenal de coulée (28) ainsi qu'une conduite enveloppante (34) placée autour du chenal de coulée (28) à proximité d'au moins l'une des surfaces de contact (22) entre les ensembles réfractaires (8, 12, 30, 32, 42, 48, 50, 60) et pourvue d'une admission (38) permettant l'entrée d'un fluide. Cette conduite enveloppante (34) est également pourvue d'une évacuation (40) destinée à laisser le fluide quitter l'installation.
