Description

Werkstoff für Teile, welche mit geschmolzenem Aluminium oder geschmolzenen Aluminiumlegierungen in Berührung kommen Flüssiges Aluminium hat eine starke Neigung zur Aufnahme von Eisen bei Berührung mit diesem Metall oder mit Legierungen, welche Eisen in größeren Mengen enthalten. In Spritzgußmaschinen, Kabelpressen u. dgl. kommt Aluminium mit Metallen in Berührung, welche Eisen als Hauptbestandteil enthalten. Ganz abgesehen davon, daß der Angriff durch das geschmolzene Aluminium zu einer Schädigung der mit ihm in Berührung kommenden Teile führt, werden auch die mechanischen Eigenschaften des Aluminiums wesentlich verschlechtert.Material for parts made with molten aluminum or molten Aluminum alloys come into contact Liquid aluminum has a strong tendency to absorb iron in contact with this metal or with alloys, which Contains iron in large quantities. In injection molding machines, cable presses and the like. aluminum comes into contact with metals, which contain iron as a main component. Quite apart from the fact that the attack by the molten aluminum leads to a Damage to the parts that come into contact with it will also affect the mechanical ones Properties of aluminum deteriorated significantly.

Gemäß der Erfindung werden die Bauteile, welche mit geschmolzenem Aluminium inBerührung kommen, aus einem gesinterten Werkstoff hergestellt, der aus einem innigen Gemenge von Eisen und Aluminium-Oxyd besteht. Es ist überraschend und war nicht vorauszusehen, daß ein Werkstoff mit einem so hohen Eisengehalt eine solche Widerstandsfähigkeit gegen flüssiges Aluminium besitzt. Beispielsweise wurde ein erfindungsgemäßer Werkstoff, der 5o Gewichtsprozent Eisen und 5o Gewichtsprozent Aluminiumoxyd enthielt, Zoo Stunden lang in flüssiges Aluminium von 75o° eingetaucht. Die Eisenaufnahme des Aluminiums betrug nur etwa o,i °/a.According to the invention, the components, which with molten Aluminum come into contact, made from a sintered material made from consists of an intimate mixture of iron and aluminum oxide. It's surprising and it was not foreseeable that a material with such a high iron content would produce one possesses such resistance to liquid aluminum. For example, was a material according to the invention, the 50 percent by weight iron and 50 percent by weight Containing aluminum oxide, immersed in liquid aluminum at 75o ° for hours. The iron uptake of aluminum was only about 0.1% / a.

Wurde ein Gußeisenstab unter gleichen Bedingungen eingetaucht, dann war die Eisenaufnahme io °/o, die Aluminiumschmelze enthielt also ioomal mehr Eisen als bei Verwendung des Werkstoffes nach der Erfindung.If a cast iron rod was immersed under the same conditions, then the iron uptake was 10 per cent, the molten aluminum thus contained 10 per cent more iron than when using the material according to the invention.

Von besonderem Vorteil ist die Verwendung des Werkstoffes aus Eisen und Aluminiumoxyd bei Spritzgußmaschinen und Kabelpressen, die aus keramischen Werkstoffen nicht gebaut werden können, die aber andererseits gegen geschmolzenes Aluminium sehr widerstandsfähig sein müssen.The use of the material made of iron is particularly advantageous and aluminum oxide in injection molding machines and cable presses made from ceramic Materials cannot be built, but on the other hand against molten aluminum must be very resistant.
