| 摘要 |
The invention relates to a plant for transferring liquid metal, in particular steel, between an upstream container (2) and a downstream container (10), comprising: an upstream container (2); a tapping spout (28); a downstream container (10), a flow regulator (26) for regulating the flow of liquid metal through the tapping spout (28); a set of refractory assemblies (8, 12, 30, 32, 64, 66, 74) which are placed between the upstream container and the downstream container, delimiting the tapping spout (28) via which the liquid metal flows from the upstream container (2) into the downstream container (10), each refractory assembly of the tapping spout (28) having at least one mating surface (22) forming a joint with a corresponding surface of an adjacent refractory assembly; a shroud channel (18; 40) placed around the tapping spout (28) near at least one mating surface (22) between refractory assemblies (8, 12, 30, 32, 64, 66, 74), this shroud channel having an inlet (44) capable of allowing the introduction of materials; in which plant means (32, 34; 36) are provided for introducing a sealing agent into the shroud channel (40; 18).
