Abstract

Method and apparatus for separating slag and pouring molten steel out of a container such as a converter or the like, which makes use of a gas jet member for jetting an inert gas into the flow of the molten steel in a descending portion of a U-shaped passage communicated with a molten steel outlet opening of the converter, whereby the gas jet causes the flow speed of the molten steel to retard so as to eliminate the influence of inertia force of the flow of the molten steel exerted to a balance between the static pressure of the residual molten steel and the static pressure of the residual slag in the U-shaped passage.
