Description

Reinigen von Gußmetallen Durch die vorliegende Erfindung wird die den Gegenstand des Hauptpatentes bildende Eifindung weiter .ausgebildet. Wie umfassende Versuche ergeben haben. können alle zur Herstellung von Gußstücken verwendeten Metalle (Hartmetalle), wie Kupfer, Nickel, Silber, Blei, Zinn, Zink, Antimon und ihre Legierungen, ebenso wie Aluminium von ihnen anhaftenden, nicht schmelzbaren Verunreinigungen befreit werden, wenn sie gemäß dein Hauptpatente mit fein gepulverter Schale von Muscheln oder einem durch Zerkleinern ähnlich beschaffener Schalen anderer Weichtiere gewonnenen Pulver behandelt werden. Zu diesen Metallen gehört nicht Gußeisen, bei dem die Bedingungen für den Erfolg cler Erfindung nicht gegeben sind.Cleaning of Cast Metals The present invention makes the The invention forming the subject of the main patent. How comprehensive Experiments have shown. can use all metals used for the production of castings (Hard metals), such as copper, nickel, silver, lead, tin, zinc, antimony and their alloys, as well as aluminum from adhering, non-meltable impurities be exempted if they are in accordance with your main patents with a finely powdered peel of Mussels or one of the shells of other molluscs made similar by crushing them recovered powder are treated. Cast iron is not one of these metals which the conditions for the success of the invention are not given.

Wesentlich für die Erzielung der der Erfindung eigenen @'irkt:ng ist, daß als Roinigungsinittel ein Pulver -verwendet wird, welches außer kohlensaurem Kalle organische Substanzen in derselben Weise enthält, wie es bei Muschelschalen oder ähnlich wie diese zusammengesetzten Schalen anderer Weichtiere der Fall ist. In der Natur vorkommender Kalkstein ist ebenso wie Kreide nicht brauchbar. Die Verwendung von Kalkstein und Kreide als Metallreinigungsmittel ist bereits bekannt.Essential for the achievement of the invention's inherent @ 'irkt: ng is, that a powder is used as a cleaning agent, which apart from carbonate It contains organic matter in the same way as it does in clams or as is the case with these composite shells of other molluscs. Limestone occurring in nature, like chalk, cannot be used. The usage of limestone and chalk as metal cleaning agents is already known.

Die Erfindung kommt in dc@r Weise zur Ausführung, daß das Gußmetall e ingeschmolzen und der flüssigen Masse. nachdem sie abgeschäumt worden ist, das Tiersclialeipulver unter Umrühren zugesetzt wird. Die dein Metalle beigemischten Verunreinigungen gelangen an die Oberfläche, und nachdem .sie durch nochmaliges Abschäumen entfernt worden sind, besitzt das Metall einen hohen Grad von Reinheit, so daß es als Gußmaterial ohne Schwierigkeiten verwendet werden kann.The invention is implemented in the manner that the cast metal e in melted and the liquid mass. after it has been skimmed off, that Animal clip egg powder is added with stirring. Who mixed your metals in Impurities get to the surface, and then through repeated Skimmings have been removed, the metal has a high degree of purity, so that it can be used as a molding material without difficulty.
