The invention relates to a sliding closure () for a metallurgical vessel comprising a tapping hole () for draining metal melt or slag, said sliding closure being provided with a slider housing () that can be secured to the vessel () and a closure plate () that can move therein for opening and closing the tapping hole (). The sliding closure () also has only this moveable closure plate (), without a stationary closure plate, which is can be moved directly on a sliding surface (), extending around the tapping hole, preferably of a casing block () in the vessel () and can be pressed by pretensioning elements. In this way, this sliding closure () provides a constructionally simpler structure and user-friendly handling.

Sliding closure for a metallurgical vessel

With a method for detecting variables in an outlet of a metallurgical vessel, different variables in the outlet are detected or measured by at least one coil surrounding the outlet channel and/or an induction coil of an induction heater as a monitoring system, wherein the variables relate to the slag portion when pouring out the metal melt, wear condition of refractory parts in the outlet channel, the solidified metal melt, flow rate and/or plugging mass in the outlet channel. After evaluation, a closure element for the outlet is actuated, heating of the metal in the outlet channel is activated and/or renewal of the outlet channel is triggered. In this way, optimum operation in the pouring of metal melt out of a vessel is simply achieved, wherein occurrence of irregularities are detected during the entire pouring, and pouring out of slag can be successfully prevented at the end of the pouring.

Method and device for detecting variables in the outlet of a metallurgical vessel

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.
