PURPOSE: Refractory assemblies are provided to improve the seal of a contacting surfaces of refractories. CONSTITUTION: A apparatus provides a set of refractory assemblies(30, 32), which is capable of being used between an upstream container and a downstream container of a plant for transferring liquid metal, in particular steel, comprising: a tapping spout(28) via which the metal flows from the upstream container into the downstream container, each refractory assembly(30, 32) of the tapping spout(28) having at least one surface forming a mating surface(22) with a corresponding surface of an adjacent refractory assembly(30, 32); a flow regulator 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(30, 32) 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.
