Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Vorliegende Erfindung bezweckt die Einführung chemischer Reagentien, welche für die Reinigung oder Legirung von Metallen erforderlich sind, mitten in den Metallflufs, derart, dafs diese Stoffe beim Eintritt in die Schmelzmasse aufser Berührung mit der atmosphärischen Luft bleiben und daher ohne theilweise vorherige Verflüchtigung voll und ganz zur Wirkung gelangen.The present invention aims to introduce chemical reagents which are useful for the Purification or alloying of metals are required, in the midst of the metal flux, in such a way that that when these substances enter the molten mass they come into contact with the atmospheric Remain air and therefore completely without partial prior volatilization come into effect.

Die Vorrichtung ist auf der beiliegenden Zeichnung in den Fig. 1 und 2 durch einen senkrechten Schnitt und eine Seitenansicht dargestellt. Sie bildet ein leicht handliches Werkzeug, welches gleichzeitig zum Umrühren der Schmelzmasse benutzbar ist.The device is on the accompanying drawing in Figs. 1 and 2 by a vertical section and a side view shown. It is an easy-to-use tool, which can be used at the same time to stir the molten mass.

Der obere Vorrathsbehälter α für die pulverförmigen Stoffe ist durch einen Klappdeckel b mittelst Scharnierschraube und Flügelmutter c verschliefsbar. Unter dem trichterförmigen Behälterboden ist ein kleines Gehäuse d angebracht, in welchem das Schaufelrad e mittelst Handkurbel f drehbar gelagert ist. Dieses Gehä'use d ist durch ein abwärts führendes Rohr g mit der unteren Mischkammer h verbunden. Letztere besitzt entweder einen offenen Boden oder, wie gezeichnet, eine Anzahl radial verlaufender Bodenöffnungen i und ist aus feuerfestem Material hergestellt. Ihre Verbindung mit dem Metallrohr g kann durch Kittmasse k und Schraubenmutter Z oder auf andere geeignete Weise erfolgen. Am unteren Ende des Rohres g ist-ein Rückschlagventil m vorgesehen.The upper storage container α for the powdery substances can be closed by a hinged lid b by means of a hinge screw and wing nut c . A small housing d is attached under the funnel-shaped container bottom, in which the paddle wheel e is rotatably mounted by means of a hand crank f. This housing d is connected to the lower mixing chamber h by a downwardly leading pipe g . The latter has either an open bottom or, as shown, a number of radially extending bottom openings i and is made of refractory material. Their connection to the metal pipe g can be done by cement compound k and screw nut Z or in another suitable manner. A check valve m is provided at the lower end of the tube g.

Beim Gebrauch wird die Vorrichtung in den Schmelztiegel ο. dgl. eingeführt, derart, dafs die Kammer h etwa 3/ SlIn use, the device is in the crucible ο. Like. Introduced in such a way that the chamber h is about 3 / S1

3/4 in die Schmelzmasse hineinreicht. Durch Drehen des Schaufelrades e mittelst der Handkurbel f wird das Pulver aus dem Vorrathsbehälter α durch das Rohr g in die Kammer h hineinbefördert. Sobald dasselbe mit der heifsen Schmelzmasse in Berührung kommt, findet eine Gas- und Dampfbildung statt, das Ventil m schliefst sich und der ganze Kammerinhalt wird durch die Bodenöffnungen / in den Schmelztiegel hineingetrieben, wobei eine innige Vermischung der Stoffe mit dem Metallflufs stattfindet; diese Vermischung kann noch durch Umrühren mit dem Werkzeug selbst gefördert werden. 3/4 extends into the melt. By turning the paddle wheel e by means of the hand crank f , the powder is conveyed from the storage container α through the pipe g into the chamber h . As soon as the same comes into contact with the hot molten mass, gas and vapor formation take place, the valve m closes and the entire contents of the chamber are driven through the bottom openings / into the crucible, whereby the substances are intimately mixed with the metal flow; this mixing can be promoted by stirring with the tool itself.

Durch die Schaufelvorrichtung kann die einzuführende Menge der Stoffe leicht geregelt werden. Das Ventil m verhindert das Entweichen der Gase und Dämpfe nach oben und .erhöht die Mischwirkung.The amount of substances to be introduced can easily be regulated by means of the scoop device. The valve m prevents the gases and vapors from escaping upwards and increases the mixing effect.
