APPARATUS FOR TRANSFERRING MOLTEN METAL, OPERATION METHOD THEREOF AND REFRACTORY ACCESSORIES

摘要

The invention relates to a set of refractory assemblies, 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 via which the metal flows from the upstream container into the downstream container, each refracotry assembly of the tapping spout having at least one surface forming a mating surface with a corresponding surface of an adjacent refractory assembly; a flow regulator for regulating the flow of liquid metal through the tapping spout; a shroud channel placed around the tapping spout near at least one mating surface between refractory assemblies and having an inlet capable of allowing the intake of a fluid; in which the shroud channel has an outlet capable of allowing the fluid to escape to the outside of the plant.
