Abstract It is proposed, in the case of at least one transport and discharge runner installed at a tapping orifice of the metallurgical furnace and a transfer station having a swivel or tilting runner in which the molten metal flows from the discharge runner by way of a distribution system into the outlet openings from which it flows into a preferably movable casting vessel, to cover the discharge runners conveying the molten metal from the tapping orifice of the metallurgical furnace with cover hoods, to screen off the transfer station in a substantially gastight manner, to sweep these interiors with inert gas and in addition to screen off the molten metal discharge stream from the outlet opening to the casting vessel by means of a pressurized inert gas covering which prevents air access and is substantially annular in cross-section. By these means, fume production is effectively avoided.
