Claims (1)

PATENT-ANSPRÜCHE : l. Elektrischer Ofen mit einer Elektrode oder mehreren Elektroden von gleicher Polarität und einem bei hohe Temperaturen elektrisch leistungsfähig werdenden Tiegel oder Schmelzgrube für die Herstellung von Stahl von irgend welchem KohlenstoCgehalt, dadurch gekennzeichnet, dass der Tiegel oder die Schmelzgrube aus einer Anzahl von Materialschichten besteht, deren Kohlenstoffgehalt von aussen nach innen aufeinanderfolgend abnimmt. PATENT CLAIMS: l. Electric furnace with one electrode or several electrodes of the same polarity and a crucible or melting pit which becomes electrically efficient at high temperatures for the production of steel of any carbon content, characterized in that the crucible or the melting pit consists of a number of material layers whose carbon content decreases successively from the outside inwards 2. Verfahren zur Inbetriebsetzung des Tiegels oder der Scbmelzgrube nach Anspruch l, dadurch gekennzeichnet, dass der Tiegel oder die Schmelzgrube vor Ingebrauchnahme des Ofens hoch erhitzt und hiedurch leitnngsfähig gemacht wird, welche Leitungsfähigkeit auch nach erfolgter Abkühlung beibehalten wird. 2. A method for putting the crucible or melting pit into operation according to claim l, characterized in that the crucible or melting pit is heated to a high level before the furnace is used and thereby made conductive, which conductivity is retained even after cooling has taken place.
