In the currently usual Procedure becomes liquid lead from a melt on a chilled Drum separated. In a subsequent stretching process is the Band material generated. The production of grids for electrodes from the material thus produced and its use in lead-acid storage batteries, due to the production-related material properties, with considerable Disadvantages connected.

Ein
weiteres Verfahren zur Herstellung von Bleilegierungsteilen für Blei-Speicherbatterie-Platten durch
Strangpressen wird in der Druckschrift
Der Erfindung liegt die Aufgabe zugrunde, ein kontinuierliches Verfahren und eine Vorrichtung zur Herstellung von Bandmaterial aus Blei oder einer Bleilegierung anzugeben, um Bandmaterial mit verbesserter Korrosionsfestigkeit, günstigen Kristallitgrößen und günstigen Kristallorientierungen des Bandmaterials zu schaffen und Einschlüsse in der Materialstruktur, beispielsweise als Lunker oder Oxidreste, zu vermeiden.Of the Invention is based on the object, a continuous process and an apparatus for producing strip material from lead or to indicate a lead alloy to strip material with improved Corrosion resistance, favorable Crystallite sizes and Great To create crystal orientations of the strip material and inclusions in the material structure, for example, as voids or oxide residues to avoid.
Die Aufgabe wird erfindungsgemäß bei einem Verfahren zur Herstellung von Bandmaterial aus Blei oder einer Bleilegierung der eingangs genannten Art dadurch gelöst, dass das Strangpressen mit Rohmaterial im festen Zustand erfolgt und das stranggepresste Bandmaterial in mehreren Stufen kaltgewalzt wird.The Task is according to the invention in a Method of making strip material from lead or a lead alloy of the type mentioned solved in that the extrusion done with raw material in the solid state and the extruded Strip material is cold rolled in several stages.
Durch das Herstellen von Blei-Bandmaterial durch Strangpressen verändert sich im Unterschied zu dem herkömmlichen Gießprozess vorteilhafterweise die Größe der Kristallite nach dem Pressvorgang nicht mehr und es wird ein gleichmäßig feinkörniges Gefüge gewonnen, da keine unterschiedlichen Materialeigenschaften durch eine ungleichmäßige Abkühlung des Materials entstehen. Durch das nachfolgende Kaltwalzen wird ein gewünschter kompakter, lamellarer Aufbau der Gefügestruktur erzeugt, so dass das Bandmaterial aus Blei oder Bleilegierungen korrosionsfester und stabiler ist.By the production of lead strip material by extrusion is changing unlike the conventional one casting process advantageously the size of the crystallites after pressing no longer and it is obtained a uniformly fine-grained structure, because no different material properties due to uneven cooling of the Materials arise. By the subsequent cold rolling is a desired produced a compact, lamellar structure of the microstructure, so that the strip material of lead or lead alloys more corrosion resistant and more stable.
Die Strangpresse wird vorzugsweise mit Blöcken aus Blei oder Bleilegierungen bestückt. Die Strangpresse kann aber auch mit Blei oder Bleilegierung im flüssigen Zustand aus einem Schmelzkessel befüllt werden, wobei die Erstarrung des Bleis in der Strangpresse erfolgt.The Extruder is preferably made with blocks of lead or lead alloys stocked. The extruder can also be used with lead or lead alloy in the liquid state filled from a melting pot with the solidification of the lead in the extruder.
Die Verarbeitungstemperatur des Bleis oder der Bleilegierung sollte beim Strangpressvorgang unterhalb des Schmelzpunktes des Bleis bzw. der Bleilegierung liegen, so dass das Material mindestens teilweise erstarrt oder zähflüssig ist.The processing temperature of the lead or the lead alloy should during the extrusion process un lie below the melting point of the lead or lead alloy, so that the material is at least partially solidified or viscous.
Es hat sich herausgestellt, dass die Materialeigenschaften des hergestellten Bandmaterials gezielt verbessert werden können, wenn das Bandmaterial nach dem Strangpressen eine Dicke im Bereich von 5 bis 50 mm und Breite im Bereich von 50 bis 500 mm hat.It has been found that the material properties of the manufactured Band material can be specifically improved when the strip material after extrusion, a thickness in the range of 5 to 50 mm and Width in the range of 50 to 500 mm has.
Besonders vorteilhaft ist es, wenn das Bandmaterial nach dem Strangpressen und vor dem Kaltwalzprozess thermisch behandelt wird. Hierdurch kann das Gefüge des Materials gezielt beeinflusst werden.Especially It is advantageous if the strip material after extrusion and is thermally treated before the cold rolling process. This can the structure of the material.
Die Dicke des Bandmaterials nach dem Kaltwalzprozess beträgt vorzugsweise 0,2 bis 3 mm. In einer besonderen Ausführungsform kann die Dicke des Bandmaterials über die Breite gesehen in dem genannten Bereich unterschiedlich sein.The Thickness of the strip material after the cold rolling process is preferably 0.2 to 3 mm. In a particular embodiment, the thickness of the Band material over the width seen in the said area be different.
Das Bandmaterial wird nach dem Kaltwalzen vorzugsweise auf Coils aufgewikkelt und bis zur weiteren Verarbeitung gelagert.The Strip material is preferably wound on coils after cold rolling and stored until further processing.
Das derart hergestellte Bandmaterial wird bevorzugt geschnitten und gestreckt und zu Gittern für Elektroden von Bleiakkumulatoren weiterverarbeitet. Aufgrund der durch das Strangpressen mit nachfolgendem Kaltwalzen gewonnenen Gefügestruktur ist das Bandmaterial hierzu besonders geeignet.The thus prepared strip material is preferably cut and stretched and to bars for Electrodes of lead-acid batteries further processed. Due to the obtained by extrusion with subsequent cold rolling Microstructure is the band material for this purpose particularly suitable.
Die Aufgabe wird weiterhin durch eine gattungsgemäße Vorrichtung mit einer Strangpresse zum Herstellen von Bandmaterial in einem Druckfließprozess aus Rohmaterial in einem festen Zustand und einer nachgeordneten Kaltwalzanlage mit einem mehrstufigen Walzwerk gelöst.The The object is further by a generic device with an extruder for Production of strip material in a pressure flow process from raw material into a solid state and a downstream cold rolling mill with a multi-stage rolling mill solved.
Die Erfindung wird nachfolgend anhand der beigefügten Zeichnungen näher erläutert.The The invention will be explained in more detail with reference to the accompanying drawings.
