KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Ueberzug.Coating.
Den Gegenstand der Erfindung bildet ein Verfahren, mittels dessen Eisen- und Stahlbleche, -Drähte, -Profilstangen und dergl. mit Aluminiumbronze überzogen werden sollen.The subject of the invention is a method by means of which iron and steel sheets, -Wires, -profile rods and the like. To be coated with aluminum bronze.
Das Verfahren kann auf zwei verschiedenen Wegen zur Ausführung gelangen.The method can be carried out in two different ways.
Nach der einen Ausführungsform wird zuerst eine Kupferplatte an ihren beiden Seiten nach Patent 110786 mit Aluminium plattirt. Sodann werden vorher gereinigte Eisen- oder Stahlplatten beiderseits mit derartigen aluminiumplattirten Kupferblechen belegt und in Retortenofen so weit erhitzt, dafs die Eisenplatten nicht oxydiren. In diesem Zustande wird das Ganze durch die Walze geschickt (oder in bestimmten Fällen geprefst oder gehämmert), wobei sich das alurniniumplattirte Kupferblech infolge seiner Weichheit so auf der Eisenplatte anschmiegt, dafs auch beim späteren Erhitzen bis zur Schweifstemperatur (Kirschrothglut) eine Oxydation des Eisenkernes nicht stattfinden kann.According to one embodiment, a copper plate is first placed on both of its sides Patent 110786 plated with aluminum. Then iron or steel plates are cleaned beforehand Covered on both sides with such aluminum-plated copper sheets and in a retort furnace heated so far that the iron plates do not oxidize. In this state the whole becomes sent through the roller (or in certain cases pressed or hammered), whereby the aluminum-plated copper sheet, because of its softness, clings to the iron plate, that also when heated up to the tail temperature (cherry red glow) Oxidation of the iron core cannot take place.
Im zweiten Arbeitsgang wird nun das Verbundmetall in einem Ofen bis zur Schweifstemperatur (ca. 9500) erhitzt, wobei, da der Schmelzpunkt des Aluminiums schon bei 7000 liegt, eine Legirung zwischen dem aufgewalzten Kupferblech und dem auf dasselbe aufplattirten Aluminium stattfindet. Diese Legirung bildet auf dem Eisenkern eine einheitliche Schicht und stellt bereits die Bronze dar. In dieser Erhitzung wird nun das Ganze durch die Walze geschickt, wobei sich die Bronze mit dem Eisen verschweifst und einen festhaftenden Ueberzug auf demselben bildet.In the second step, the composite metal is heated in a furnace up to the welding temperature (approx. 950 0 ), whereby, since the melting point of the aluminum is already 700 0 , an alloying takes place between the rolled-on copper sheet and the aluminum plated on it. This alloy forms a uniform layer on the iron core and already represents the bronze. In this heating, the whole is now sent through the roller, the bronze welding together with the iron and forming a firmly adhering coating on it.
Bei der zweiten Ausführungsform wird eine nur auf einer Seite nach Patent 110786 mit Aluminium plattirte Kupferplatte verwendet.In the second embodiment one is only on one side according to patent 110786 with Aluminum clad copper plate used.
Derart plattirte Kupferbleche werden nun mit der Aluminiumseite auf den Eisenkern gebracht und in der vorher beschriebenen Weise zuerst mäfsig erwärmt, gewalzt, dann geglüht und geschweifst. Dadurch wird eine durch eine Aluminium-Kupfer-Legirung mit dem Kupferblech verbundene Eisenplatte erhalten, und befindet sich an der Oberfläche reines Kupfer.Copper sheets plated in this way are now brought onto the iron core with the aluminum side and first moderately heated, rolled, then annealed in the manner described above and curly. This creates an aluminum-copper alloy with the Copper plate is preserved, and is pure on the surface Copper.
In einem weiteren Arbeitsgang wird die Kupferoberfläche dieser' Platte gereinigt und nochmals nach PatenA 110786 mit Aluminium plattirt, ausgewalzt und geglüht, wobei von der Oberfläche aus nach innen zu sich wiederum eine Kupfer-Aluminium-Legirung bildet, welche jetzt die gewünschte Bronze darstellt.In a further step, the copper surface of this' plate is cleaned and again clad with aluminum according to PatenA 110786, rolled out and annealed, whereby from from the surface towards the inside, in turn, forms a copper-aluminum alloy, which now represents the desired bronze.
Die zweite Ausführungsform des Verfahrens wird dann angewendet, wenn es sich um solche (vornehmlich aluminiumreiche) Legirungen handelt, welche unter der WTalze brüchig werden würden.The second embodiment of the method is then applied when it is such (mainly aluminum-rich) alloys, which Alze under the W T would be brittle.
Durch die richtige Wahl der Stärke des Aluminium- und Kupferbleches hat man es in der Hand, aluminiumreiche oder -arme Bronzen zu erzeugen.By choosing the right thickness of the aluminum and copper sheet, you have it in to produce bronzes that are rich or poor in aluminum.
Die Herstellung von Drähten und Profilstangen geschieht in gleicher Weise, wobeiThe production of wires and profile bars is done in the same way, whereby
die zur Verwendung kommenden Walzen mit entsprechenden Profilen versehen sein müssen.the rollers used must be provided with appropriate profiles.
