Abstract: 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.

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.

Abstract: A copper anode furnace includes a furnace drum which can be pivoted about a horizontal axis and in which copper melt is refined into anode copper by fire refining. The furnace drum is provided with a spout for pouring out the refined copper. A sliding closure is arranged on the spout of the furnace drum. The sliding closure includes at least one stationary, fireproof closing plate and a fireproof sliding plate which can be displaced relative to the closing plate. Through the displacement of the sliding plate, the outflow out the furnace drum can be regulated or closed and therefore the outflow amount of the copper can be controlled. A drawing of slag into the casting, which reduces the anode quality, can be prevented using the sliding closure.

Abstract: A copper anode furnace comprises a furnace drum (2), which can be pivoted about a horizontal axis and in which copper melt is refined into anode copper by means of fire refining. Said furnace drum (2) is provided with a spout (10) for pouring out the refined copper. A sliding closure (20) is arranged on the spout (10) of the furnace drum (2). Said sliding closure comprises at least one stationary, fireproof closing plate (21) and a fireproof sliding plate (22) which can be displaced relative to said closing plate. Through the displacement of the sliding plate (22), the outflow out the furnace drum (2) can be regulated or closed and therefore the outflow amount of the copper can be controlled. A drawing of slag into the casting, which reduces the anode quality, can be prevented using said sliding closure (20).
