AUSGEGEBEN AM 11. JUL11925ISSUED ON JUL 11, 1925

Streckt, zieht oder walzt man Metalle auf kaltem Wege, so muß man das Metall, welches sich unter der Einwirkung der mechanischen Behandlung erhärtet, zwischen jedem Stich ausglühen und scheuern. Um diese langwierigen und kostspieligen Arbeitsvorgänge auszuschalten und gleichzeitig den Verbrauch an Schmiermitteln zu vermindern, hat man vorgeschlagen, die Oberfläche des zu bearbeitenden Werkstücks mit einer dünnen Schicht Blei oder Bleilegierung zu überziehen, welche infolge ihrer Dehnbarkeit die Rolle eines Schmiermittels spielt. Das Verbleien wird gewöhnlich dadurch erreicht, daß man das zu bearbeitende, vorher gescheuerte Werkstück, in ein Bleibad oder ein Bleilegierungsbad eintaucht oder einen elektrolytischen Niederschlag erzeugt.If you stretch, draw or roll metals in a cold way, you have to choose the metal, which hardens under the action of mechanical treatment, between each stitch annealing and scrubbing. To eliminate these lengthy and costly operations while reducing consumption To reduce lubricants, it has been proposed to treat the surface of the Work piece to be coated with a thin layer of lead or lead alloy, which due to its elasticity the Role of a lubricant. The lead is usually achieved by the previously scrubbed workpiece to be processed is placed in a lead bath or a lead alloy bath immersed or generated an electrolytic precipitate.

Alle diese Verfahren erfordern umfaingreiche und kostspielige Anlagen; außerdem ist es außerordentlich schwierig, eine Bleischicht oder eine Schicht aus Bleilegierung zu erhalten, die fest genug anhaftet, um das Werkstück mehreren aufeinanderfolgenden Arbeitsstufen unterwerfen zu können, ohne daß die Bleischicht oder Bleilegierungsschicht sich vom Metall trennt.All of these processes require extensive and expensive equipment; aside from that it is extremely difficult to have a layer of lead or a layer of lead alloy to obtain that adheres firmly enough to the workpiece several consecutive times To be able to subject work stages without removing the lead layer or lead alloy layer separates from the metal.

Diesen Mängeln wird durch das den Gegenstand der Erfindung bildende Verfahren abgeholfen, welches darin besteht, daß man die Oberfläche des zu bearbeitenden, vorher mittels bekannter Mittel gescheuerten Werkj Stücks amalgamiert, so daß eine gewissermaßen eindringende Schicht gebildet wird, deren Reibungskoeffizient auf den Zieheisen, Dornen, Walzwerkswalzen o. dgl. seht gering ist, so daß man das Arbeitsstück mehreren aufeinanderfolgenden mechanischen Behandlungen unterwerfen kann, ohne daß noch eine besondere Arbeitsstufe erforderlich ist.These deficiencies are remedied by the method forming the subject of the invention, which consists in that the surface of the work to be processed, previously scrubbed by known means Partly amalgamated so that a more or less penetrating layer is formed, their coefficient of friction on the drawing iron, mandrels, rolling mill rolls or the like is low is so that the workpiece can be subjected to several successive mechanical treatments can subject without a special stage of work being required.

Das Verfahren gemäß der Erfindung ist also begreiflicherweise von ganz besonderer Wichtigkeit für das Strecken und Ziehen der Metalle, insbesondere bei der Herstellung von aus Stahl gezogenen Röhren und Profilen.The method according to the invention is therefore understandably very special Importance for the stretching and drawing of the metals, especially in the production of tubes and profiles drawn from steel.

Um das Verfahren auszuführen, braucht man nur beispielsweise ein rohes Stahlrohr blank zu scheuern und z. B. in eine wässerige Lösung einzutauchen, die 10 g Quecksilberchlorid pro Liter enthält. Es bildet sich dann auf der Oberfläche des Stahls ein Amalgam, welches ermöglicht, daß das Rohr mehreren aufeinanderfolgenden Streckvorgängen unterworfen werden kann, ohne daß es ausgeglüht oder blankgescheuert zu werden braucht.A raw steel pipe, for example, is all that is needed to carry out the method to scrub bare and z. B. immerse in an aqueous solution containing 10 g of mercury chloride per liter contains. An amalgam then forms on the surface of the steel, which enables the tube to be subjected to several successive stretching operations without it needing to be annealed or scoured bright.
