Abstract

A steel smelting furnace has a tundish outlet rapidly discharging liquid metal. The outlet zone has especially a fire-resistant ceramic cover which reduces the ferrostatic pressure in the vicinity of the outlet. The cover has a number of apertures through which the molten metal flows. The cylindrical base section is extended and diverts the molten metal, reducing surge flow and associated vortices.
