Description
Verfahren zum Reinigen von metallischen Schmelzflüssen Gegenstand der Erfindung ist ein Verfahren, .welches gestattet, metallische Schmelzflüsse von darin enthaltenen ungeschmolzenen Bestandteilen, insbesondere Oxyden, vollkommen und schnell zu reinigen. Das Verfahren ist in erster Linie zum Reinigen von Leichtmetallen, deren Oxyde schwerer sind als das Metall und sich deshalb nicht leicht von dem flüssigen Metall trennen lassen, oder von Legierungen solcher Metalle bestimmt, kann aber auch mit Vorteil für gewisse Schwermetalle benutzt werden.Process for cleaning metallic melt fluxes object of the invention is a method .which allows metallic melt flows from unmelted components contained therein, especially oxides, completely and quick to clean. The process is primarily for cleaning light metals, the oxides of which are heavier than the metal, and are therefore not easily separated from the liquid Let metal separate, or determined by alloys of such metals, but can can also be used with advantage for certain heavy metals.
Die Erfindung besteht darin, daß der geschmolzenen Metallmasse ein Mineralpulver zugesetzt wird, das in feiner Verteilung eine organische Substanz enthält, die in der geschmolzenen Metallmasse zur Verkohlung bzw. Verbrennung gebracht wird. Durch die hierbei an sehr vielen gleichmäßig über die Metallmasse verteilten Stellen stattfindende Gasentwicklung werden die in der flüssigen Metallmasse enthaltenen ungeschmolzenen Metallteile an die Oberfläche gebracht, von der sie durch Abschäumen leicht entfernt werden können.The invention consists in that the molten metal mass a Mineral powder is added, which is finely divided an organic substance contains, which are brought to charring or combustion in the molten metal mass will. Due to the very many evenly distributed over the metal mass Places that take place gas development are contained in the liquid metal mass Unmelted metal parts brought to the surface, from which they are skimmed can be easily removed.
Es ist bekannt, bei. der Herstellung von Flußeisen und Stahl zum Zwecke der Desoxydation der geschmolzenen Metallmasse in diese organische Substanzen, wie z: B. Sägespäne, einzuführen. Für die Erfindung, ist es aber wesentlich, zu verhindern, daß schon an der Oberfläche der Metallmasse vorzeitig eine Verkohlung bzw. Verbrennung der organischen Substanz eintritt. Dies geschieht dadurch, daß die organische Substanz in einem Mineralpulver sehr fein verteilt wird, so daß die Mineralkörnchen die organische Masse kurze Zeit vor dem thermischen Angriffe der Schmelze schützen.It is known at. the production of fluoro iron and steel for the purpose the deoxidation of the molten metal mass into these organic substances, such as e.g. to introduce sawdust. For the invention, however, it is essential to prevent that already on the surface of the metal mass a charring or burning prematurely the organic matter enters. This happens because the organic matter in a mineral powder is very finely divided, so that the mineral granules the organic Protect the compound from thermal attack by the melt for a short time.
Es ist auch schon zur Erzeugung dichter und gleichmäßiger Güsse aus Kupfer und dessen Legierungen vorgeschlagen worden, dem Schmelzsatz und der Schmelze Natriumbicarbonat ebenfalls zum Hervorbringen einer Gasentwicklung hinzuzusetzen (Patentschrift 179 $17). Dieses Salz zersetzt sich aber schon unter loo°.It is also already used to produce dense and even casts Copper and its alloys have been proposed, the melt set and the melt Add sodium bicarbonate also to produce gas evolution (Patent 179 $ 17). However, this salt already decomposes below 100 °.
Der Schmelzpunkt der mineralischen Masse, welche die zur Verkohlung bzw. Verbrennung kommende organische Substanz in sehr feiner Verteilung enthält, muß höher liegen als der der zu reinigenden Metallmasse.The melting point of the mineral mass which is responsible for charring or combustion contains organic matter in very fine distribution, must be higher than that of the metal mass to be cleaned.
Zur Ausführung der Erfindung kann z. B. eine leim- oder hornartige Substanz in Verbindung mit - Kieselgur oder Kreide benutzt werden.To carry out the invention, for. B. a glue or horn-like Substance can be used in conjunction with - diatomaceous earth or chalk.
