Description

Verfahren zur Herstellung von Verbundmetallkörpern. Die Erfindung betrifft ein Verfahren zur Herstellung von Verbundmetallen, und zwar sollen ungleiche Metalle von hoher Schmelztemperatur so .innig miteinander verbunden werden, JäB sie sich nicht trennen lassen. Nach bekannten Verfahren wird das eine Metall um das andere gegossen, beispielsweise Kupfer um- Eisen, und zwar von oben her, wodurch Luft mitgerissen und Luftblasen gebildet und diese in. der Form festgehalten werden. Infolgedessen sah man sich genötigt, Desoxydationsmittel einzuführen. Die Erhitzung erfolgt in gewöhnlichen Glühöfen, was eine genaue Regelung und Konstant-. erhaltung der Hitze ausschließt.Process for the production of composite metal bodies. The invention relates to a process for the production of composite metals, specifically intended to be unequal Metals with a high melting temperature are so intimately connected to one another, Yeah they cannot be separated. According to known methods, the one metal is around the other cast, for example copper around iron, from above, whereby Air is entrained and air bubbles are formed and these are held in the mold. As a result, one felt compelled to introduce deoxidizing agents. The heating takes place in ordinary annealing furnaces, which means precise regulation and constant-. conservation which excludes heat.

Nach,der vorliegenden Erfindung wird eine gereinigte Fläche des einen Metalles, beispielsweise Eisen, mit einer geschmolzenen Masse des anderen Metalles, beispielsweise Kupfer, in innige Berührung gebracht, worauf durch Erhitzung des einen Metalles durch den elektrischen Strom auf _ etwa die Schmelztemperatur des anderen Metälles und die Konstanterhaltung dieser Hitze während des Vorganges eine Verschweißung der beiden Metalle herbeigeführt wird.According to the present invention, a cleaned area of the one Metal, for example iron, with a molten mass of the other metal, for example copper, brought into intimate contact, whereupon by heating the a metal by the electric current to _ about the melting temperature of the other metal and the maintenance of this heat during the process Welding of the two metals is brought about.

Die Erhitzung durch den elekirischen Strom hat den Vorteil, daß die Temperatur genau geregelt und während der ganzen Dauer des Vorganges konstant erhalten werden kann:, wodurch die innige Verbindung der beiden ungleichen Metalle gewährleistet wird. Die Anordnung von Glühöfen mit ihren Nachteilen wird erspart.The heating by the electrical current has the advantage that the The temperature is precisely regulated and kept constant for the entire duration of the process can be: which ensures the intimate connection of the two dissimilar metals will. The arrangement of annealing furnaces with their disadvantages is spared.

Eine Ausführungsform des Verfahrens ist in der beiliegenden Zeichnung dargestellt in Fig. i im Längsschnitt, in Fig. 2 im Grundriß mit Schnitt nach Linie A-B der Fig. i; in Fig. 3 in etwas anderer Ausführung.One embodiment of the method is in the accompanying drawing shown in Fig. i in longitudinal section, in Fig. 2 in plan with section along the line A-B of Figure i; in Fig. 3 in a slightly different embodiment.

Ein Eisenbarren oder eine Eisenplatte d mit metallisch reiner Oberfläche wird in die Gießform b -gebracht- und das Eisen durch Entfernung oderVerdrängung des Sauerstoffs während er Erhitzung metallisch rein erhalten. Die Erhitzung des Barrens auf die-erforderliche Schweißhitze erfolgt erst nach der Verdrängung des Sauerstoffes--durch den elektrischen Strom, welcher beispielsweise durch kühlbare Kontakte c und' d am oberen und unteren Ende oder auf andere Weise zugeführt wird. Alsdann wird zweckmäßig durch eine Öffnung e im Boden der Gießform das Überzugsmetall, beispielsweise Kupfer, eingeführt. Die Zuführung des Überzugsmetalls von unten her hat den Vorteil, daß alle Gase aus dem Rauare verdrängt werden, so daß eine innige Berührung zwischen dem flüssigen Kupfer und . der erhitzten Oberfläche der Eisenplatte gewährleistet ist.An iron bar or an iron plate d with a metallic surface is placed in the mold b and the iron is removed or displaced keep the oxygen metallically pure during heating. The heating of the Barrens to the required welding heat takes place only after the displacement of the Oxygen - through the electrical current, which, for example, through coolable Contacts c and 'd at the top and bottom or in some other way. Then the coating metal is expediently through an opening e in the bottom of the casting mold, for example copper, introduced. The supply of the coating metal from below has the advantage that all gases are displaced from the Rauare, so that an intimate Contact between the liquid copper and. the heated surface of the iron plate is guaranteed.

Die überschüssigen Gase können -aus dem oberen Teil der Gießform abgeleitet werden. Nach Abtrennung des oberen Kopfteiles des Kernes wird der Verbundblock ausgewalzt und gezogen.The excess gases can be discharged from the upper part of the casting mold will. After separating the upper head part of the core, the composite block is rolled out and pulled.
