The invention pertains to a process and an apparatus for the discontinuous tapping of melts. An inductor surrounds a passage through which the melt is discharged from a vessel. The inductor applies radial electromagnetic energy to the passage to maintain the melt in a molten state. To stop flow of the melt through the passage, an outlet opening of the passage is closed and the inductor is electrically switched off while a cooling medium is flowed through the inductor. To begin flow of the melt, the outlet opening of the passage is opened and the inductor is electrically switched on.

[What is claimed is:] [1.]interrupting flow of a melt from a vessel through a passage;flowing a cooling medium through an inductor that surrounds said passage while said inductor is electrically switched off, whereby the melt solidifies within said passage;ceasing the interruption of the flow of the melt through said passage; andelectrically switching on said inductor, whereby radial electromagnetic energy is applied to the solidified melt within said passage such that the solidified melt within said passage becomes molten and flows through said passage.
