Verfahren zur Herstellung von Bogenlichtelektroden.Process for the production of arc light electrodes.
: Um, die Lichtausbeute des elektrischen: Um, the luminous efficiency of the electric
Bogenlichtes zu erhöhen, hat man den Kohleiielektroden Metall bezw. Metallverbindungen als lichtfärbende Substanzen unter Zusatz von Flußmitteln, wie Borsäure, calcinierte Soda, Wasserglas usw., zugesetzt. Da die Mischung der Metall- bezw. Metalloidverbindungen mitTo increase the arc light, one has the carbon electrodes Metal or Metal compounds as light-coloring substances with the addition of fluxes such as boric acid, calcined soda, Water glass, etc., added. Since the mixture of metal respectively. Metalloid compounds with
." den Flußmitteln in den Kohlenstiften keine vollkommen gleichmäßige war, so entstanden. "the flux in the carbon pins was not perfectly uniform, so emerged
ίο beim Brennen der letzteren an den weißglühenden Elektrodenenden Schmelzpunkte von wechselnder Zusammensetzung und verschiedenen Eigenschaften. Die leichter- flüssigen Schlacken saigerten aus den streng flüssigen aus und setzten sich als feste Schlacken an den Kohlenstiften ab, wodurch der Lichtflammenbogen ungünstig beeinflußt wurde und schließlich abbrach.ίο when burning the latter to the incandescent Electrode ends melting points of varying composition and different Properties. The lighter, liquid slags segregated from the strictly liquid ones and settle as solid slag on the carbon pins, creating the arc of the flame was adversely affected and finally broke off.
Ein weiterer Übelstand der Schlackenabsonderung war der,'daß die Hauptmasse der zur:Another disadvantage of slag secretion was that 'that the main mass of the:
Lichtfärbung' dienenden Stoffe mit der abge-Light coloring 'serving substances with the
. setzten Schlacke verloren ging, so daß man mehr Metall- bezw. Metalloidverbindungen der rohen Kohlenstiftmasse zusetzen mußte, als zur Erzielung einer guten Lichtausbeute erforderlich war. Infolge der dadurch bedingten großen Mengen von Zusätzen zu der Kohlenstiftmasse wurde der Ohm'sche Widerstand der fertigen Kohlenstifte erhöht, und dieselben zeigten eine geringere Festigkeit.. put slag was lost, so that one more metal respectively. Metalloid compounds of had to add raw carbon stick mass than necessary to achieve a good light output was. As a result of the resulting large amounts of additives to the carbon stick mass the ohmic resistance of the finished carbon pins was increased, and the same showed lower strength.
Um diese Übelstände zu beseitigen, werden nach vorliegender Erfindung Metalle oder Metalloide und deren Verbindungen, mit Ausschluß der Karbide unter Zusatz von Flußmitteln, wie Wasserglas, calcinierte Soda usw. und Borsäure, Borax, Boronatroncalcit usw., welche Verbindungen des Bors ein ruhiges Brennen des Lichtbogens bewirken, zusammengeschmolzen, wodurch Glasflüssebzw. Schlacken von bestimmter Konstitution und bestimmten lichtfärbenden Eigenschaften erzeugt werden, welche der rohen Kohlenstiftmasse als feingemahlenes Pulver zugesetzt werden (jedoch mehr als 3 Prozent). Da nun jedes kleinste Teilchen dieser pulverisierten, lichtfärbenden Verbindungen gleiche Zusammensetzung besitzt, so ist ein Aussaigern von leichtflüssigen Schlacken nicht mehr oder nur in geringem Maße möglich, wodurch obige Übelstände der Lichtflammenbogenkohlen wegfallen. Ebenso können diese Glasflüsse bezw. Schlacken derart den Kohlenelektroden zugesetzt werden, daß erstere mit wenig Ruß, Kohlenstiftpulver und Teer den. inneren Kern oder äußeren Mantel der Kohlenelektroden bilden. Zweckmäßig ist es auch, diese Kohlenelektroden derart auszubilden, daß die gewöhnlichen Kohlenstifte ent- weder mit Rinnen zur Atifnahme der lichtfärbenden Glasflüsse oder Schlacken versehen oder daß die letzteren in Form eines Ansatzes an den Elektroden angebracht werden.In order to eliminate these inconveniences, metals or according to the present invention Metalloids and their compounds, with the exclusion of carbides with the addition of fluxes, such as water glass, soda ash etc and boric acid, borax, boronatron calcite etc, which connections of the boron cause a calm burning of the arc, melted together, whereby glass liquid or Slags of a certain constitution and certain light-coloring properties are generated, which the raw charcoal stick mass as finely ground Powder can be added (but more than 3 percent). Since now every smallest Particles of these powdered, light-coloring compounds have the same composition, so there is little or no more liquid slag to be sucked out Dimensions possible, whereby the above inconveniences of the light flame arcs are eliminated. as well can these glass flows bezw. Slags are added to the carbon electrodes in such a way that the former with a little soot, pencil powder and tar. inner core or outer sheath of the carbon electrodes. It is also useful to design these carbon electrodes in such a way that that the ordinary charcoal pencils either have grooves for receiving the light-coloring ones Glass flows or slags provided or that the latter in the form of an approach attached to the electrodes.
