Abstract
Slide closure unit on the spout of a metallurgical vessel, preferably a copper-anode furnace, includes a housing in which refractory closure plates, as well as at least one connecting refractory inner casing, are arranged. A removable induction heater is provided, having at least one induction coil surrounding the refractory inner casing outside of the housing. In this way, it is possible to constantly keep the melt located in the outlet channel of the spout sufficiently warm so that it does not freeze before and/or during the pouring of the melt, or that any frozen metal and/or slag can be melted in the spout.
