Abstract:
A set of refractory assemblies for transferring liquid metal between an upstream container and a downstream container, the set comprising:(a) a plurality of refractory assemblies, comprising a first refractory assembly having a mating surface for mating with a corresponding mating surface of an adjacent second refractory assembly that is capable of movement relative to the first refractory assembly; (b) a tapping spout formed by the refractory assemblies through which the metal flows from the upstream container into the downstream container; (c) a flow regulator for regulating the flow of liquid metal through the tapping spout; and (d) a shroud channel circumscribing the tapping spout and opened to the mating surface between the first and second refractory assemblies, and the shroud channel having an inlet capable of allowing the intake of a fluid and an outlet capable of allowing the fluid to escape from the refractory assemblies.
