Abstract

The invention relates to a method for the slag-free removal of molten steel from distributors and ladles that are used in an aftertreatment process. During said method, the base outlets (10, 15, 16) are opened and the slag cover (8, 14) is prevented from being carried along with the metal by means of baffles (21, 22) that interrupt or significantly retard the vortices that occur in the vicinity of the base outlets (10, 15, 16). The baffles (21, 22) that are allocated to the base outlets (10, 15, 16) thus act as vortex breakers (20), so that slag cannot be carried off with the metal. The pins (41) that are provided to fix the vortex breakers (20) on or in the distributor base (24) or ladle base (25) preferably take the form of a cylinder (56).
