Method and device for discontinuous parting off of molten mass

摘要

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.
