In the process indicated, the slag floating on the molten baths in the case of a relatively high level of the molten baths towards the end of tapping sinks to the pouring orifice in the vessel bottom, which can be closed or controlled by means of a slider seal or flap seal. In order to avoid dispersion of slag, caused by metal streams, towards the end of the tapping process, so that slag-free molten metal can still be tapped until just before the closing position is reached, that is to say in order to obtain a recovery of more than 95% of molten metal, it is proposed that a flow body (11), fixed to a lifting device (7) in vertical alignment with the tapping orifice (13) of the slide seal or flap seal (2), is held in a position in the upper part of the melt (3), that, when a residual quantity of molten metal (3) with a critical level of the molten bath of 200-500 mm above the upper edge of the tapping orifice of the open slide seal or flap seal (2) is reached, the flow body (11) is lowered into a lower position about 30 to 50 mm above the base (1c) of the vessel bottom and that the outflow of the melt is stopped when the level of the molten bath sinks down to the base (1c) of the vessel bottom. <IMAGE> |
