Description
Verfahren zur Herstellung künstlicher Edelsteine Künstliche Edelsteine (Korun@de) werden bekanntlich in der Weise hergestellt, daß man (las pulvrige Ausgangsmaterial, Aluminiumoxyd, mit oder ohne Zusatz färbender Oxyde, in einem Schmelzraum auf das von einer Schmelzflamme umspülte Ende eines Tragstiftes streut, auf dem sich .dann eine Perle geschmolzener Steinmasse bildet. Diese Schmelzperlen werden nach ihrer Abkühlung zerteilt und auf Schmucksteine sowie Lagersteine für Uhren, Elektrizitätszähler und andere Meßgeräte weiterverarbeitet.Process for the production of artificial gemstones Artificial gemstones (Korun @ de) are known to be produced in such a way that (the powdery starting material, Aluminum oxide, with or without the addition of coloring oxides, in a melting chamber on the Scattered by a melting flame around the end of a support pin on which .dann forms a bead of molten stone mass. These melting pearls are after their Cooling down and on gemstones as well as bearing stones for watches, electricity meters and other measuring devices processed.
Die so erzeugten Steine enthalten häufig Einschlüsse von feinen Gasbläschen, die unter Umständen in feinster Form in großen Scharen auftreten und dann als Trübung der sonst klaren Steinmasse erscheinen. Diese Poren beeinträchtigen nicht nur ,die Schönheit der Steine, sondern auch ihre technische Verwertbarkeit, weil sie, durch den Schliff freigelegt, muhe Laufflächen für die Stahlzapfen bilden und dadurch eine rasche Zerstörung der Zapfen herbeiführen.The stones produced in this way often contain inclusions of fine gas bubbles, which may appear in the finest form in large flocks and then as cloudiness the otherwise clear stone mass. These pores not only affect that Beauty of the stones, but also their technical usability because they, through Uncovered the joint, they have to form running surfaces for the steel pegs and thereby cause rapid destruction of the cones.
Die nach dem bekannten Verfahren erzeugten Lagersteine haben außerdem die nachteilige Eigenschaft, leicht zu zerspringen.The jewels produced by the known method also have the disadvantageous property of being easily broken.
Gegenstand der Erfindung ist ein verbessertes Verfahren zur Herstellung der künstlichen Edelsteine und eine Einrichtung zur Ausübung dieses Verfahrens. Das Ziel der Verbesserung ist die vollkommene Homogenität der Steinmasse, im besonderen die Vermeidung aller Gaseinschlüsse.The invention relates to an improved method of manufacture of artificial gemstones and a facility to practice this process. The aim of the improvement is the perfect homogeneity of the stone mass, in particular the avoidance of all gas inclusions.
Nach der Erfindung wird dieses Ziel erreicht durch eine besonders weitgehende Auflockerung des pulvrigen Ausgangsmaterials vor seiner Überführung in den Schinelzrattin.According to the invention, this aim is achieved by a special extensive loosening of the powdery starting material before its transfer in the Schinelzrattin.
Es ist möglich, völlig homogene, kugelige oder linsenförmige Schmelzperlen von einigen Millimeter Durchmesser mit einem verschwindend kleinen Halsteil herzustellen, die durch Einschleifen einer oder zweier Laufflächen ohne sonstige Bearbeitung in Spurpfannen für Elektrizitätszähler umgewandelt werden können.It is possible to create completely homogeneous, spherical or lenticular melting beads a few millimeters in diameter with an infinitely small neck part, by grinding in one or two running surfaces without any other processing in Track pans for electricity meters can be converted.
Die weitgehende Auflockerung des Ausgangsmaterials, das in an sich bekannter Weise einem Gasstrom überliefert und durch ihn dem Schmelzraum zugeführt wird, wird nach der Erfindung dadurch erreicht, daß das Material durch einen gegen die Oberfläche einer Schüttung des Materials gerichteten Gasstrahl zerstäubt wird.The extensive loosening of the starting material, which in itself in a known manner delivered to a gas stream and fed through it to the melting chamber is, is achieved according to the invention in that the material by a counter the surface of a bed of the material directed gas jet is atomized.
Das verbesserte Verfahren soll mit Hilfe der Zeichnung näher erläutert werden, auf der die Einrichtung zur Ausübung des Verfahrens und Erzeugnisse des Verfahrens dargestellt sind.The improved method is explained in more detail with the aid of the drawing on which the facility to carry out the process and products of the Procedure are shown.
Fig. i ist das Schema einer Einrichtung zur Ausübung des Verfahrens.Fig. I is the schematic of a device for practicing the method.
Fig.2 zeigt .den Zerstäuber dieser Einrichtung im (Querschnitt in vergrößertem Maßstab, Fig. 3 einen Teil des Zerstäubers in perspektivischer Darstellung.Fig. 2 shows the atomizer of this device in (cross-section in on an enlarged scale, FIG. 3 shows a part of the atomizer in a perspective illustration.
