  Verfahren und Ofen zum Erschmelzen von   plattenförmigen   Quarzgeoenttänden. 



   Es ist bekannt, röhrenförmige Gegenstände aus Quarz dadurch herzustellen, dass man um einen   stabförmigen   Widerstand Quarzsand schichtete, diesen durch einen eingeleiteten starken Strom schmolz und hierauf den Widerstand aus   der geschmolzenen Röhre herauszog.   



  Es konnten aus diesen Röhren durch Aufblasen oder ähnliche Handhabungen verschiedenartige Quarzgegenstände hergestellt werden, jedoch nur solche von geringen Abmessungen.

  Zu diesem Zwecke wird gemäss der Erfindung durch Aneinanderreihung einer grösseren Anzahl solcher röhrenförmigen Formlinge ein   Werkstück   von erheblicher Ausdehnung hergestellt, aus welchem die Widerstände gleichzeitig durch Zurückziehen der sie tragenden beweglichen Ofenwand herausgezogen werden können. Diese von Löchern durchsetzte Platte wird nunmehr unmittelbar nach dem Schmelzen in noch bildsammem Zustand unter die Presse gebracht, welche 
 EMI1.2 
 heitliche ebene Platte von beliebigen Ahmessungen herstellt. 



   Ein wesentliches Merkmal der Erfindung besteht darin, dass der Abstand der Ofen-und   Formwände,   welche parallel zu der durch die Widerstände bestimmten Fläche liegen, verstellbar ist, so dass die Dicke der Schmelzlinge geregelt werden kann. 



   Auf der Zeichnung ist ein Ofen   dargestHt, mit dessen Hilfe   sich vorliegende Erfindung durchführen lässt und welcher die Herstellung dicker Platten aus Kieselsäure ermöglicht.

   Der Ofen besteht aus   einer gusseisernen   Platte, deren   Enden aufwärtsgebogen   sind, so dass zwei   Seitenwände entstehen. D 'Deckel A   besteht aus zwei Teilen, die in der Mitte durch

  Method and furnace for melting plate-shaped quartz objects.



   It is known to manufacture tubular objects made of quartz by layering quartz sand around a rod-shaped resistor, melting it using a strong current introduced and then pulling the resistor out of the molten tube.



  Various types of quartz objects could be produced from these tubes by inflation or similar manipulations, but only those of small dimensions.
 EMI1.1
 



  For this purpose, according to the invention, by stringing together a large number of such tubular moldings, a workpiece of considerable size is produced from which the resistors can be pulled out simultaneously by pulling back the movable furnace wall that supports them. This plate, interspersed with holes, is now brought under the press immediately after melting in a still picture-collectable state
 EMI1.2
 produces uniform flat plate of any measurement.



   An essential feature of the invention is that the distance between the furnace and mold walls, which are parallel to the surface determined by the resistors, is adjustable so that the thickness of the fused parts can be regulated.



   The drawing shows a furnace with the aid of which the present invention can be carried out and which enables the production of thick sheets of silica.



   Fig. 1 is a side view of the furnace,
Fig. 2 is a plan view.



   Fig. 3 is a side view, partly in section, with the oven inverted.



   Figure 4 is a side view from the other side with the oven in the normal position

   The stove consists of a cast iron plate, the ends of which are bent upwards so that two side walls are created. D 'lid A consists of two parts that go through in the middle

 connected is. The other bottom is formed by a door C which is mounted on a trolley b. The latter moves on rails c.
 EMI1.5
 Bottom, while the other is used to line the lid. The longitudinal division of the graphite plate used for the cover has the purpose of increasing the free movement of the joints a.



   The iron bands have spindles with flat, square heads. Some of them are embedded in the graphite plate.
 EMI1.6
   and quartz plates of various thicknesses can be produced in this way. These wheels, f are held in place by means of bushings connected to the top and bottom of the box.
