Abstract

In order to impede entrainment or trailing of molten slag (1) while tapping molten metal (2) from a metallurgical vessel (5) having a tap hole (1) in the bottom (13) of said vessel, the molten slag (1) is blown away from the surface of the molten metal in the area of the tap hole (10) (2) by a gas jet (9) with high impulsive energy.
