Description
Elektrischer Ofen zur Ausübung des Verfahrens zum Schmelzen von Leichtmetallen Das Hauptpatent 541046 betrifft ein Verfahren zum Schmelzen von Leichtmetallen, bei dem das Schmelzgut erst durch Induktionsheizung und dann durch Strahlungsheizung mittels Heizwiderständen erhitzt wird. Es werden dadurch ungünstige Erscheinungen zu starker Badbewegung durch die Induktionserhitzung vermieden.Electric furnace for carrying out the process of melting light metals The main patent 541046 relates to a method for melting light metals, in which the melting material is first heated by induction and then by radiant heating is heated by means of heating resistors. This results in unfavorable phenomena Avoid excessive bath movement due to induction heating.
Die Erfindung, welche sich gleichfalls auf das Schmelzen von Leichtmetallen, wie Aluminium, Zink o. dgl.,, bezieht, betrifft einen elektrischen Ofen zur Durchführung des Verfahrens nach dem Hauptpatent, indem der durch Heizwiderstände beheizte Teil des Ofens als mit dem durch Induktionsheizung beheizten Teil des Ofens in Verbindung stehender besonderer Schöpftiegel ausgebildet ist. Zweckmäßig wird der Schöpftiegel seitlich neben dem Induktionsschmelzraum angeordnet und eine Trennwand vorgesehen, welche den Übertritt der bei Leichtmetallen sich stark bildenden Schlacken vom Induktionsschmelzraum in den Schöpftiegel verhindert. Der neue Ofen zeichnet sich durch einfache Bauart aus; er - ermöglicht es, die Schmelze aus dem widerstandsbeheizten Tiegel auszuschöpfen; ferner ergibt sich eine gute Sichtbarkeit der in dem widerstandsbeheizten Teil des Ofens befindlichen Schmelze, so daß sich der Schmelzbadspiegel durch Zugabe neuen Materials leicht konstant halten läßt; schließlich ist die Gefahr des Einfrierens des auf genaue Temperatur zu haltenden Schmelzgutes vermieden.The invention, which also relates to the melting of light metals, such as aluminum, zinc or the like refers to an electric furnace for implementation of the process according to the main patent, in which the part heated by heating resistors of the furnace than in connection with the part of the furnace heated by induction heating standing special ladle is formed. The ladle becomes useful arranged laterally next to the induction melting chamber and a partition is provided, which allows the slag, which is strongly formed in light metals, to pass from the induction melting chamber prevented in the ladle. The new furnace is characterized by its simple design the end; it - enables the melt to be scooped out of the resistance-heated crucible; furthermore, there is good visibility of the in the resistance-heated part of the Furnace located melt, so that the melt pool level by adding new Material can easily be kept constant; after all, there is a risk of freezing of the melting material to be kept at the exact temperature avoided.
Die Erfindung sei beispielsweise an Hand der Zeichnung erläutert.The invention is explained, for example, with reference to the drawing.
Der Ofen besteht aus dem Induktionsschmelzraum i und dem Schöpftiegel 2. Durch den Transformator 3 wird das in der Rinne 4 befindliche Metall erhitzt und gleichzeitig eine starke Durchwirbelung des Bades in dem Schmelzraum i erzielt. Zwischen dem Induktionsschmelzraum i und dem Schöpftiegel 2 befindet sich eine Trennwand 5, welche den Übertritt der Schlacken von dem Induktionsschmelzraum in den Schöpftiegel verhindert und gleichzeitig eine Dämpfung der Badbewegung für die in dem Schöpftiegel befindliche Schmelze bewirkt. Im Schöpftiegel sind die Widerstandsheizkörper 6 angeordnet, durch welche die Schmelze weiter erwärmt und insbesondere am vorzeitigen Erstarren verhindert wird. Zweckmäßig werden die Heizkörper selbsttätig elektrisch geschaltet, und zwar durch eine Regeleinrichtung, welche in Abhängigkeit von der Temperatur der Schmelze im Schöpftiegel arbeitet.The furnace consists of the induction melting chamber i and the ladle crucible 2. The metal in the channel 4 is heated by the transformer 3 and at the same time a strong turbulence of the bath in the melting chamber i is achieved. There is a partition between the induction melting chamber i and the ladle 2 5, which shows the passage of the slag from the induction melting chamber into the ladle crucible prevents and at the same time a damping of the bath movement for those in the ladle causes located melt. The resistance heating elements 6 are arranged in the ladle, through which the melt is further heated and in particular due to premature solidification is prevented. The radiators are expediently switched electrically automatically, namely by a control device, which depends on the temperature the melt in the ladle works.
Die im Ausführungsbeispiel beschriebene Vorrichtung kann verschiedentliche Änderungen erfahren; so kann z. B. der Schmelzraum i als eine mittels Hochfrequenzinduktionsspule beheizte Trommel ausgebildet sein.The device described in the embodiment can be various Experience changes; so can z. B. the melting chamber i as a high-frequency induction coil be formed heated drum.
