Description
Nach dem Verfahren des Patents 420848 werden die zu plattierenden Metallbänder den Walzen gesondert von Bandhaspeln zugeführt. Dadurch wird ermöglicht, die Erwärmung jedes Bandes besonders zu bewerkstelligen. Hierdurch kann das Plattieren und das Schweißen einerseits wesentlich vereinfacht, anderseits wesentlich erweitert werden, da bekanntlich Aluminium bei einer Erhitzung auf 3500 C und mehr bis fast zu seinem Schmelzpunkt mit oxydfreien Flächen anderer entsprechend erwärmter Metalle unter Druck schweißbar bleibt.According to the method of patent 420848, the metal strips to be clad are fed to the rolls separately from strip reels. This enables each strip to be heated in a special way. Thereby, the plating and the welding on the one hand considerably simplified, on the other hand be substantially extended, since it is known aluminum is weldable when heated to 350 0 C and more almost to its melting point with oxide-free surfaces of other metals according heated under pressure.
Sind beim Verschweißen von Eisenbändern mit Aluminiumbändern die Stärkenverhält-When welding iron strips with aluminum strips, are the strength ratios
• nisse der zu verschweißenden Bänder derart, daß die eine Bandsorte wesentlich stärker als die andere ist, so kann das Zusammenwalzen nach dem Hauptpatent, das bei Erhitzung beider Metalle auf etwa 3500 C stattfindet, auch erfolgen, wenn nur das stärkere Metall diese Erwärmung besitzt, das dünnere aber kalt bleibt. Das dünnere Band nimmt nämlich unter dem Walzdruck sofort die notwendige • Nisse of the bands to be welded such that one band type is much stronger than the other, the rolling together according to the main patent, which takes place when both metals are heated to about 350 ° C., can also take place if only the stronger metal has this heating , the thinner but stays cold. The thinner strip immediately takes what is necessary under the rolling pressure
ag Wärme von dem erhitzten starken Bande an, und das Zusammenschweißen erfolgt dann in gleich vollkommener Weise, als ob beide Metalle auf etwa 3500 C erhitzt wären. Das Plattieren wird dadurch wesentlich vereinfacht, da man nur mit einem erhitzten Metall zu arbeiten braucht.ag heat from the heated strong band, and the welding together then takes place in the same perfect manner, as if both metals were heated to about 350 ° C. The plating is made much easier because you only need to work with a heated metal.
Da, wie oben angeführt, Aluminium bei seiner Erhitzung über 3500 C bis fast zu seinem Schmelzpunkt unter Druck mit oxydfreien Flächen anderer Metalle schweißbar bleibt, so 3S ist es beim Plattieren des Aluminiums mit dem Eisen noch möglich, durch höhere Erhitzung des Aluminiumbandes ein unmittelbares Zusammenschweißen des Aluminiumbandes mit dem Eisenband ohne vorheriges Zusammenwalzen zu bewirken. Hierzu ist das Eisenband bis zu seiner Oxydationsgrenze auf etwa 3500 C und das Aluminiumband auf etwa 5500C zu erhitzen; beim Zusammenführen der so erhitzten Bänder unter den Walzen erfolgt dann unmittelbar die sofortige innige Verschweißung beider Metalle. Das Plattieren erfolgt somit in einem Arbeitsgang statt in zweien.Since, as stated above, aluminum is weldable at its heating above 350 0 C until almost the other to its melting point under pressure by oxide-free surfaces of metals, so 3S it is still possible in plating of the aluminum with the iron by higher heating of the aluminum strip a direct To cause the aluminum strip to be welded to the iron strip without prior rolling. For this purpose, the iron strip is to be heated up to its oxidation limit to about 350 ° C. and the aluminum strip to about 550 ° C.; When the heated strips are brought together under the rollers, the two metals are immediately and closely welded together. Plating is done in one operation instead of two.
Durch vorbeschriebene beliebige Erwärmung jedes einzelnen Metallbandes ist es auch möglich, aufgehaspelte Zinkbänder sehr vorteilhaft mit Aluminiumbändern zu verschweißen. Dazu ist das Zinkband auf etwa 250 ° C, das Aluminiumband auf etwa 4500 C zu erhitzen, und-es erfolgt dann zwischen den Walzen die Verschweißung beider Metalle in einem Arbeitsgang.By heating each individual metal strip as required, it is also possible to weld reeled zinc strips very advantageously to aluminum strips. For this purpose, the zinc tape to about 250 ° C to heat the aluminum strip to about 450 0 C, and it-then takes place between the rollers, the welding of the two metals in a single operation.
Wie vorstehende Beispiele zeigen, sind durch die unmittelbare gesonderte Zuführung der zu plattierenden Metallbänder zu den Walzen und die hierdurch leicht zu bewerkstelligenden verschiedenen Erwärmungen der Bänder wesentliche Vereinfachungen der Zu-As the above examples show, the direct separate feed the metal strips to be clad to the rollers and the ones that are easy to accomplish as a result various heating of the strips, substantial simplifications of the
sammenschweißung von Aluminiumbändern mit Metallbändern und Anwendung dieser Verfahren auf andere Metalle in großem Umfange möglich.Joint welding of aluminum strips with metal strips and their application Processes on other metals possible on a large scale.
Da für Plattierungen mit Aluminium praktisch nur Eisen, Zink und wohl auch Kupfer in Frage kommen, so sind hier nur vorgenannte Beispiele des neuen Verfahrens angeführt worden. Es ist aber natürlich auch mög-Hch, andere mit Aluminium plattierfähige Metalle oder Metallegierungen hiernach zu behandeln. Das Verfahren ist auch auf Formmetalle aller Art von entsprechenden walzbaren Querschnitten sinngemäß anwendbar.-Since for cladding with aluminum practically only iron, zinc and probably also copper come into question, only the aforementioned examples of the new method are given here been. But it is of course also possible, others that can be plated with aluminum Treat metals or metal alloys accordingly. The process is also applicable to shaped metals all types of corresponding rollable cross-sections can be used accordingly.
