Forehearth
Definition
A reception basin or external refractory compartment situated in front of the taphole of a cupola or blast furnace, serving for the temporary collection, homogenization, and temperature maintenance of molten iron or liquid metal before casting. This structural element optimizes the metal smelting process by allowing lighter residual slag to separate at the surface.
