  Elektrischer   Strahlungsofen zum   Erhitzen und   Brennen von Gegenständen.

 EMI2.1 
 Gegenstände herauszunehmen, ist das Gewölbe 12 mit in der Zeichnung nicht gezeichneten Hebevorrichtungen versehen. 



   Die Anordnung eines Ofens gemäss Fig. 3 mit drei Elektroden 2 bringt den Vorteil, dass ein besonderer Bodenkontakt nicht erforderlich wird, wenigstens nicht bei Drehstrom. Dazu kommt, dass der Nutzeffekt gesteigert wird, weil man im Stande ist, in einen kleineren Ofenraum sowohl mehr Kraft zu verwenden als auch mehrere Gegenstände auf einmal zu brennen bzw. zu erhitzen. Die zu erhitzenden Gegenstände werden in Reihen auf jeder Seite der Wärmequelle angebracht und vorzugsweise so angeordnet, dass sämtliche ungefähr   dieselbe. Wärmemenge   pro Zeiteinheit erhalten, um zu verhindern, dass, wenn einige derselben fertig erhitzt sind, andere noch beheizt werden   müssen, wodurch   die ersteren einer   Überhitzung   ausgesetzt werden. 



   PATENT-ANSPRÜCHE :
1. Elektrischer Strahlungsofen zum Erhitzen und Brennen von Gegenständen mittels eines oder mehrerer in der Mitte des Ofenraumes angeordneter Lichtbogen, dadurch gekennzeichnet, dass die Gegenstände um eine zur wärmeerzeugenden Einrichtung parallele Achse drehbar angeordnet sind.

 EMI2.1
 To remove objects, the vault 12 is provided with lifting devices not shown in the drawing.



   The arrangement of a furnace according to FIG. 3 with three electrodes 2 has the advantage that a special ground contact is not required, at least not with three-phase current. In addition, the efficiency is increased because one is able to use both more power and to burn or heat several objects at once in a smaller furnace space. The items to be heated are placed in rows on either side of the heat source and are preferably arranged so that they are all approximately the same. Obtained amount of heat per unit of time in order to prevent that when some of them are finished heating, others still have to be heated, thereby exposing the former to overheating.



   PATENT CLAIMS:
1. Electric radiation furnace for heating and firing objects by means of one or more arcs arranged in the middle of the furnace chamber, characterized in that the objects are arranged rotatably about an axis parallel to the heat-generating device.

Claims (1)

2. Elektrischer Strahlungsofen nach Anspruch l, dadurch gekennzeichnet, dass der die Gegenstände tragende Boden in einzelne Platten unterteilt ist, von welchen jede für sich um ihre vertikale Achse drehbar ist. 2. Electric radiation furnace according to claim l, characterized in that the floor carrying the objects is divided into individual plates, each of which can be rotated about its vertical axis. 3. Ofen nach Anspruch 1 und 2, dadurch gekennzeichnet, dass die drehbaren Tragplatten aus dem Ofenraum heraushebbar angeordnet sind. 3. Furnace according to claim 1 and 2, characterized in that the rotatable support plates are arranged so that they can be lifted out of the furnace space. 4. Ofen nach Anspruch 1 bis 3, dadurch gekennzeichnet, dass die drehbaren Platten in Reihen zu beiden Seiten einer aus mehreren hintereinander angeordneten Elektroden bestehenden wärmeerzeugenden Anordnung gelagert sind. EMI2.2 4. Oven according to claim 1 to 3, characterized in that the rotatable plates are mounted in rows on both sides of a heat-generating arrangement consisting of several electrodes arranged one behind the other.
