  Verfahren und elektrisch beheizter Schachtofen zur Gewinnung von Metallen auch aus armen Erzen. 
 EMI1.1 
 Ofenschachteseingeführt. 



   Diese Einrichtung bat den Nachteil. dass das Gewölbe des Schmelzraumes in unmittelbarer Näbe des LIehtbogens sich befinden muss und daher ausserordentlich stark beausprucht wird. Dieser Übelstand konnte auch nicht dadurch beseitigt werden. dass man

 Schachtöfen nicht möglich gewesen. 



   Im   nachfolgenden   wird eine Ausführungsform des Ofens der Erfindung an Hand einer schematischen Zeichnung beschrieben. 



   A sind die seitlich angeordneten Schächte. die in den Schmelzraum B führen. In diesen reichen die Elektroden C senkrecht durch das Gewölbe D hinein. Im Boden dieses

   PATENTANSPRÜCHE :
1. Verfahren zur Gewinnung von Metallen auch aus armen Erzen, Schlacken und   mdoren   Abfällen des   Hüttonbetriebes,   dadurch gekennzeichnet, dass die beim reduzierenden   fh nelzen   im Schachtofen fallende   metalloxydhaltige   Schlacke auf dem Schmelzbade durch   frelorennende   Lichtbögen durch Aufbringung von Kohlenstoff oder in sonst geeigneter
Weise in der fUr die Stahlgewinnung bekannten Art von-ihrem Metalloxydgehalt befreit wird, und zwar unter Ausschluss des Zutrittes von Sauerstoff oder sonstiger oxydierender
Gase in demselben Verfahren, in dem die Reduktion des Ausgangsmaterials erfolgt.

  Process and electrically heated shaft furnace for the extraction of metals, also from poor ores.
 EMI1.1
 Furnace shaft introduced.



   This facility took the disadvantage. that the vault of the enamel space must be in the immediate vicinity of the arc and is therefore extremely stressed. This problem could also not be eliminated. that he

 Shaft furnaces were not possible.



   In the following, an embodiment of the furnace of the invention is described with reference to a schematic drawing.



   A are the shafts arranged on the side. which lead into the melting chamber B. The electrodes C extend perpendicularly through the arch D into this. In the bottom of this

   PATENT CLAIMS:
1. Process for the extraction of metals from poor ores, slag and mudor waste from the Hütton factory, characterized in that the metal oxide-containing slag falling in the shaft furnace during the reducing felzen is deposited on the melt pool by freezing arcs by the application of carbon or otherwise
The manner known for steelmaking is freed of its metal oxide content, with the exclusion of oxygen or other oxidizing agents
Gases in the same process in which the starting material is reduced.

Claims (1)

2. Eloktrisch beheizter Reduktionsofen (Schachtofen) zur Ausführung des Verfahrens nach Anspruch 1, dadurch gekennzeichnet, dass der an die seitlichen Schächte sich an- schliessende Herdschmelzraum so erweitert ist, dass die Beschickung die freibängenden Elektroden nicht umspült und dass die Anbringung von Türen zur Überwachung des Betriebes und zur Einführung von Zuschlägen ermöglicht ist. 2. Electrically heated reduction furnace (shaft furnace) for carrying out the method according to claim 1, characterized in that the hearth melting chamber adjoining the side shafts is widened so that the charge is free-hanging Electrodes not washed around and that the attachment of doors to monitor the operation and to introduce surcharges is possible.
