<p>For the purposes of transferring a predetermined amount of liquid metal from a vessel (1) containing a molten metal bath (2) into a receiving container (3), there is provided a discharge flow pipe (4) which has a refractory lining and which is in the form of an inverted U or V with two downwardly pointing limbs (5, 6) of which the first has an intake opening and the second has an outlet opening for the liquid metal, which outlet opening can be gas-tightly closed by a closure means. Provided in the upper region of the discharge flow pipe (4) is a pipe connection (14) which has a refractory lining and which can be communicated with a vacuum means (19, 20). The discharge flow pipe is dipped with its first limb (5) into the molten metal bath (2) and the liquid metal is removed on the basis of the principle of a liquid siphon.</p> |
