Patentiert im Deutschen Reiche vom 30. Juni 1931 abPatented in the German Empire on June 30, 1931

Es ist bekannt, Platten und Tafeln aus härterem Metall, ζ. Β., Eisen, mit einem einseitigen Überzug aus weicherem Metall, z. B. Kupfer, zu versehen, indem zwei Platten des härteren Metalls mit ihren oberen Flächen zusammengelegt und die frei liegenden Flächen rings mit einem Mantel umgössen werden, worauf das so erhaltene Werkstück einem Walzprozeß ausgesetzt wird. Für die Herstellung verbleiter Zinkbleche oder gar -bänder hat dies Verfahren nie Anwendung gefunden. \It is known to use plates and panels made of harder metal, ζ. Β., Iron, with a one-sided Coating made of softer metal, e.g. B. copper, by placing two plates of the harder metal with their top surfaces put together and the exposed areas are encased with a coat, whereupon the workpiece thus obtained is subjected to a rolling process. For the production of leaded zinc sheets or even - tapes, this procedure has never been used. \

Vor Jahrzehnten ist schon einmal gelegentlich vorgeschlagen worden, verbleite Zinkbleche herzustellen durch Zusammenwalzen von Zinkplatten mit Bleiplatten. Man hat aber nie davon gehört, daß verbleite Zinkplatten auf den Markt gekommen wären. Wahrscheinlich ist ihre Fabrikation auf nichtDecades ago it was proposed occasionally that leaded zinc sheets were used produced by rolling together zinc plates with lead plates. But no one has ever heard of leaded zinc plates on the market. Probably their manufacture is not on

so überwundene Schwierigkeiten gestoßen infolge der verschiedenen Schiebungen, die bei der üblichen Paketwalzung der Zinkplatten zwischen Blei und Zink eintreten.difficulties so overcome encountered as a result of the various shifts that occurred the usual rolling of the zinc plates between lead and zinc.

Es wurde nun gefunden, daß sich inIt has now been found that in

as billiger und einwandfreier Weise bleiplattiertes Zink in der Weise herstellen läßt, daß auf Zinkgußblöcke Blei aufgebracht wird und aus den beiden Metallen durch Verwalzung verbleite Zinkbänder hergestellt werden.as cheap and flawlessly lead-plated Can produce zinc in such a way that lead is applied to zinc cast blocks and leaded zinc strips can be produced from the two metals by rolling.

Die bei der Verwalzung entstehenden erheblichen Abschnitte können in Raffinieröfen wieder auf walzfähiges Zink mit normalem Bleigehalt verschmolzen werden, während der Überschuß an Blei sich als Ofenblei, das aufs neue bei der Plattierung Verwendung finden kann, ausscheidet.The considerable sections resulting from rolling can be put into refining furnaces re-melted on millable zinc with normal lead content, during the Excess lead turns out to be furnace lead, which is used again in plating can find, ruled out.

Man hat schon vorgeschlagen, das chemisch relativ leicht angreifbare Zink durch Plattierung mit Aluminium zu schützen. Ganz abgesehen davon, daß aluminiumplattiertes Zink den Nachteil hat, weniger gut gelötet werden zu können und den meisten chemischen Einflüssen schlechter widersteht als bleiplattiertes Zink, hat das Aluminiumplattierverfahren den Nachteil, daß die Fabrikationsabfälle mit S und mehr Prozent Aluminium durchaus nicht billig zu raffinieren oder sonst zu verwerten sind.It has already been suggested that zinc, which is chemically relatively easily attacked, can be removed by plating protect with aluminum. Not to mention the aluminum-plated zinc has the disadvantage that it is less easy to solder and that it is exposed to most chemical influences resists worse than lead-plated zinc, the aluminum plating process has the disadvantage that the production waste with S and more percent aluminum by no means can be refined cheaply or otherwise recycled.

Man arbeitet in der Weise, daß man auf die gerade erstarrten rauhen Zinkgußblöcke, die etwa eine Temperatur von 4000 haben, geschmolzenes Blei, dessen Erstarrungstemperatur bei 3270 liegt, gießt. Das Blei verteilt sich dann nahezu gleichmäßig; ein Überschuß wird beim Vorwalzen abgepreßt.Is carried out in such a manner that one is poured into the just solidified rough Zinkgußblöcke that require approximately a temperature of 400 0, molten lead, the solidification temperature is at 327 0th The lead is then distributed almost evenly; an excess is squeezed out during roughing.
