feuerbeständigem isolierenden Material eingelegt ist Hiedurch verringert sich der Querschnitt der Masse 8, während gleichzeitig der Stromweg verlängert wird Anstelle der Rippe 2 ist hier als Stütze der Schicht 3 ein Ring 9 aus feuerbeständigem, isolierendem Material eingefügt.
Wenn der Heizkörper in die Wand oder den Boden des Ofens eingesetzt werden soll, so gibt man ihm zweckmässig die Form nach Fig. 3, Das Graphitrohr 16 wird in einen Ring 12 der Ofenwand eingesetzt, der mit der Wand aus einem Stück bestehen oder von ihr isoliert sein kann.
Das Rohr wird durch einen Deckel 1. 1 abgeschlossenen und die Räume 15 zwischen dem Deckel und dem Rohr 16, sowie die Räume 14 zwischen dem Ring 12 und dem Rohr werden mit einer 'elektrisch leitenden Masse ausgeatampft. Anstatt des Einstampfens kann man auch das Rohr durch Glasieren mit den benachbarten Teilen verbinden, indem man die Zwischenräume mit einer Glasurmasse ausfüllt, deren Schmelzpunkt höher liegt als der der Charge, und die Masse durch starkes Erhitzen des Rohres zum Schmelzen bringt.
PATENTANSPRÜCHE :
1. Elektrischer Heizkörper für metallurgische Ofen, dadurch gekennzeichnet, dass am Boden des Heizkörpers ein mit diesem in elektrisch leitender Verbindung stehendes, als zweite Elektrode dienendes Kohlenstück befestigt ist.

Fire-resistant insulating material is inserted. This reduces the cross-section of the mass 8, while at the same time the current path is lengthened. Instead of the rib 2, a ring 9 made of fire-resistant, insulating material is inserted here as a support for the layer 3.
If the radiator is to be inserted into the wall or the floor of the furnace, it is expediently given the shape according to FIG. 3. The graphite tube 16 is inserted into a ring 12 of the furnace wall, which is made of one piece with the wall or of it can be isolated.
The tube is closed off by a cover 1.1 and the spaces 15 between the cover and the tube 16 and the spaces 14 between the ring 12 and the tube are evacuated with an electrically conductive mass. Instead of tamping, the tube can also be connected to the neighboring parts by glazing, by filling the gaps with a glaze compound whose melting point is higher than that of the batch and melting the compound by heating the tube.
PATENT CLAIMS:
1. Electrical heating element for metallurgical furnace, characterized in that a piece of carbon which is in an electrically conductive connection and serving as a second electrode is attached to the bottom of the heating element.
