A B S T R A C T An improved device used for teeming liquid metal out of a metallurgical container comprises an efficacious cross section which is formed by the surface of the discharge channel available for the outflow of the metal during the progressive opening of the upper outflow passage. This efficacious cross section is initially kept small and over at least a noticeable part of its length the discharge channel is provided with an active passage portion showing a shaped cross section. This shaped portion stretches down to the lower extremity of the channel and has a form comparable to that one of a star with three to four branches, whereas the grounds of these branches extend axially in the direction of the outflow and serve as guides to the metal during its discharge.
