Mit einer Aluminiumlegierung überzogenes Eisen.
Das bis jetzt hergestellte, mit Aluminium oder mit aluminiumreichen Legierungen überzogene Eisen liess sich in der Glühhitze des Eisens nicht bearbeiten, noch wieder weichglühen, da die Schmelzpunkte der bezüglichen Überzüge durchweg innerhalb der Schmelzgrenze des Aluminiums (zirka 7000 C) lagen. Dieser Umstand machte sich namentlich bei der Herstellung von Walzfabrikaten, wie Blechen, Drähten, Stangen, Rohren, die bekanntlich fast stets in der Glühhitze des Eisens vor sich geht, wozu auch das Wiederweichgliihen des Eisens bei dieser Temperatur zu rechnen ist, nachteilig fühlbar und erschwerte auch eine innige Legierung des Überzuges mit dem hiezu vielfach bei zirka 6500 C noch zu kalten Eien. Diese Übelstände zu vermeiden, bezweckt die vorliegende Erfindung.
Die Grundlage derselben bildet die Erkenntnis, dass der Herstellung von hochschmelzbaren, aluminiumreichen Legierungen, deren Schweissfähigkeit in der bezüglichen Temperaturhohe
EMI1.1
Bekanntlich assen sich hochschmelzbare, aluminiumreiche Legierungen durch Zusätze von höher schmelzenden anderen Metauen, wie Nickel, Eisen, Wolfram, Iridium, Zer, Thor, Kobalt und andere, zu dem Aluminiuni herstellen, und eignet sich beispielsweise eine AluminiumWolfram-Kobalt-LegierungfürvorhegendenZweck.
Das Aufbringen eines derartigen Überzuges auf dem Eisen geschieht dann in bekannter Weise durch oxydationsfreies Zusammenbringen des Einsens mit dem Überzug und Verschweissen beider Metalle unter Druck (Walzen. Pressen, Hämmern, Hämmern) bei ihrer, in diesem Falle aber hei zirka 800 bis 1000 C liegenden, Schweisstemperatur.

Iron coated with an aluminum alloy.
The iron that has been produced up to now and coated with aluminum or with alloys rich in aluminum could not be processed in the annealing heat of the iron, nor could it be soft annealed again, since the melting points of the coatings in question were consistently within the melting limit of aluminum (approx. 7000 C). This fact made itself disadvantageously palpable and difficult in the manufacture of rolled products such as sheets, wires, rods, and tubes, which, as is well known, almost always takes place in the annealing heat of the iron, including the re-softening of the iron at this temperature also an intimate alloy of the coating with the egg, which is often too cold at about 6500 ° C. The present invention aims to avoid these inconveniences.
The basis of the same is the knowledge that the production of high-fusible, aluminum-rich alloys, their weldability in the relevant temperature
EMI1.1
It is known that refractory, aluminum-rich alloys can be produced by adding higher-melting other metals such as nickel, iron, tungsten, iridium, zer, thor, cobalt and others to the aluminum, and an aluminum-tungsten-cobalt alloy, for example, is suitable for this purpose.
Such a coating is then applied to the iron in a known manner by bringing together the inset with the coating and welding together both metals under pressure (rolling, pressing, hammering, hammering) without oxidation, at their temperature, which in this case is around 800 to 1000 C. , Welding temperature.
