FIELD: metallurgy.
SUBSTANCE: furnace bottom is provided with two outlet openings for molten metal, the distance between centres of which corresponds at least to twofold, and mainly fourfold value of the diameter of the outlet opening. Outlet openings have equal diameters and can be closed independently from each other by means of gate valves.
EFFECT: reduction of the metal tapping from the furnace, increase of service life of outlet openings, prevention of slag particles capture at metal tapping owing to improving hydrodynamics of metal flow in the outlet opening area.
