BOTTOM FOR A METALLURGICAL VESSEL WITH A DIRECT CURRENT ELECTRIC ARC DEVICE

摘要

The invention relates to a bottom for a metallurgical vessel with a direct current electric arc device, whereby the cathode of said device protrudes into the vessel and at least one anode is placed in the fire-resistant lining of said bottom. One end of the anode penetrates the wall of the vessel and comes into contact with the molten metal mass inside the vessel. The other end of the anode can be connected to sources supplying cooling fluid. The anode is secured to the wall of the vessel by means of fixing elements and is electrically insulated. A sleeve (31) which does not conduct electric current is also provided. Said sleeve covers the part of the anode (21) that protrudes into the metallurgical vessel (11) and forms a discharge channel (37) having a dimension ( DELTA r), which is arranged at a distance from the anode (21) in such a way that low melt metals, essentially lead, can flow out of the vessel (11) without any hindrance.
