Description
Die Erfindung betrifft ein Verfahren zum Herstellen von Blechen aus einer Magnesiumschmelze.The The invention relates to a method for producing metal sheets a magnesium melt.
Magnesiumflachprodukte werden zunehmend im Bereich des Karosseriebaus und vergleichbaren Anwendungsgebieten für die Erzeugung von besonders leichten und gleichzeitig formstabilen Bauteilen eingesetzt.Magnesium flat products are increasingly in the field of body shop and comparable Application areas for the production of particularly lightweight and dimensionally stable components used.
Eine
vorteilhafte Art und Weise der Herstellung von Bändern mit bestimmter Dicke
stellt das so genannte "Gießenwalzen" dar, bei dem eine
Metallschmelze zu einem Band mit einer endabmessungsnahen Dicke
vergossen und unmittelbar anschließend inline zu einem Warmband
warmgewalzt wird. Die erhaltenen gegossenen und warmgewalzten Bänder werden
daraufhin weiter prozessiert. Dabei können weitere Walzschritte oder
andere Umformoperationen sowie Glühbehandlungen eingeschlossen sein
(
Die Breite der auf diese Weise erzeugten Bänder ist durch die Breite des Walzspalts des zu ihrer Umformung eingesetzten Walzgerüstes beschränkt. Durch Längsteilen können aus diesen Bändern lediglich so genannte "Spaltbänder" abgeteilt werden, deren Breite kleiner ist als die Breite des Ausgangsproduktes. Allerdings besteht seitens der Anwender von derartigen Flachprodukten nicht nur die Forderung nach einem weiten Spektrum unterschiedlichster Dicken, sondern es werden auch an den jeweiligen Verwendungszweck angepasste Breiten verlangt, die über die auf konventionellen Walzstraßen erzeugbaren Breiten hinausgehen.The Width of the tapes produced in this way is determined by the width of the Limited roll gap of the mill used for their transformation. By slitting can from these tapes only so-called "slit strips" are divided, whose width is smaller than the width of the starting product. Indeed does not exist on the part of users of such flat products only the demand for a wide range of different Thickness, but it will also depend on the intended use custom widths that are above those on conventional rolling mills range that can be generated.
Ausgehend von dem voranstehend erläuterten Stand der Technik bestand die Aufgabe der Erfindung darin, ein Verfahren anzugeben, das auf einfache Weise die Herstellung von Magnesiumblechen größerer Breite und guten mechanischen Eigenschaften ermöglicht.outgoing from the above Prior art, the object of the invention was a method to specify that in a simple way the production of magnesium sheets of greater width and good mechanical properties.
Diese Aufgabe ist durch ein Verfahren der eingangs angegebenen Art gelöst worden, bei dem erfindungsgemäß folgende Arbeitsschritte durchlaufen werden:
- – Erschmelzen der Magnesiumschmelze,
- – Vergießen der Magnesiumschmelze zu einem gegossenen Band,
- – im unmittelbaren Anschluss an das Vergießen erfolgendes Bandwalzen des gegossenen Bandes zu einem gewalzten Band,
- – Querteilen des gewalzten Bandes zu Blechen,
- – Walzen der Bleche auf eine Enddicke, wobei bezogen auf die Bleche das Walzen der Bleche in einer quer zur Walzrichtung des Bandwalzens ausgerichteten Richtung durchgeführt wird, die während des gesamten Walzens der Bleche beibehalten wird.
- Melting the molten magnesium,
- Casting the molten magnesium into a cast strip,
- Immediately following the casting, strip rolling of the cast strip into a rolled strip,
- - dividing the rolled strip into sheets,
- - rolling the sheets to a final thickness, wherein with respect to the sheets, the rolling of the sheets is carried out in a direction transverse to the rolling direction of the strip rolling direction, which is maintained during the entire rolling of the sheets.
Gemäß der Erfindung wird zunächst in an sich bekannter Weise aus einer Magnesiumschmelze ein gegossenes Band erzeugt, dass eine bestimmte, durch die zum Walzen eingesetzten Aggregate begrenzte Breite besitzt. Anschließend werden von diesem Band Bleche abgeteilt. Diese Bleche werden anschließend quer zur Längsrichtung des Bandwalzens erforderlichenfalls in mehreren Stichen so lange gewalzt, bis einerseits die gewünschte Breite und andererseits die geforderte Dicke erreicht sind. "Richtung des Walzens der Bleche" meint hier stets die Ausrichtung, mit der das Blech in den nächstfolgenden Walzstich eintritt. D.h., das unmittelbar nach dem Abteilen von dem gegossenen und gewalzten Band noch in Längsrichtung des Bandes ausgerichtete Blech wird beispielsweise so um eine senkrecht auf der Blechoberfläche stehende Achse gedreht, dass seine ursprünglich gleich der Längsrichtung des Bandes ausgerichtete Richtung nun quer zu dieser ausgerichtet ist. Auf diese Weise lassen sich technisch besonders einfach sehr breite Tafeln erzeugen, die den vom Endverwerter aufgestellten Forderungen entsprechen.According to the invention will be first in a conventional manner from a molten magnesium a cast Band generates that one, through which used for rolling Aggregates has limited width. Subsequently, from this band Sheets divided. These sheets are then transverse to the longitudinal direction the strip rolling if necessary in several stitches as long rolled, on the one hand the desired Width and on the other hand the required thickness are reached. "Direction of rolling the sheets "means here always the orientation with which the sheet in the next Walzstich enters. That is, immediately after dividing the cast and rolled strip still aligned in the longitudinal direction of the tape For example, sheet metal is placed perpendicular to the sheet surface Axis turned that his original equal to the longitudinal direction the band oriented direction is now aligned transversely to this. In this way it is technically very easy to get very wide Create panels that meet the demands made by the end-user correspond.
Es zeigt sich, dass erfindungsgemäß erzeugte Bleche gute mechanische Eigenschaften und eine für ihre Weiterverarbeitung günstige Gefügestruktur aufweisen. Dabei sind die Abweichungen zwischen den in Längs-, Quer- und Diagonalrichtung der erfindungsgemäß erzeugten Bleche ermittelten Eigenschaften gering. Neben dem Vorteil, ein Blech großer Breite herstellen zu können, stellen sich bei erfindungsgemäßer Vorgehensweise somit bereits die positiven Effekte ein, die für ein mit mehrfachen Richtungswechseln erfolgendes Walzen von Magnesiumblechen bereits in der Fachliteratur beschrieben sind (Beck, Adolf "Magnesium und seine Legierungen", Springer Bln, 2. Auflage 2001, Kapitel: Technologie des Walzens). Überraschend ist dabei, dass die erzielten Eigenschaftsverbesserungen bei erfindungsgemäßer Weise des Walzens eintreten, obwohl die vom Band abgetrennten Bleche lediglich einmal so bewegt werden, dass ihre Ausrichtung beim Walzen von der Ausrichtung abweicht, mit der das Band gewalzt worden ist.It shows that produced according to the invention Plates have good mechanical properties and a favorable microstructure for their further processing exhibit. The deviations between the longitudinal and transverse and diagonal direction of the sheets produced according to the invention determined properties low. In addition to the advantage of being able to produce a sheet of large width can provide in the case of the procedure according to the invention thus already the positive effects, which for one with multiple changes of direction Successful rolling of magnesium sheets already in the literature are described (Beck, Adolf "Magnesium and its alloys ", Springer Bln, 2nd edition 2001, chapter: Technology of rolling). Surprised is that the property improvements achieved in inventive way of the rolling, although the separated from the strip sheets only once be moved so that their orientation when rolling from the alignment deviates, with which the tape has been rolled.
Das Walzen der Bleche kann erforderlichenfalls in mehreren Walzstichen durchgeführt werden, um besonders dünne, breite Bleche zu erzeugen. Wird ein mehrstufiges Walzen durchgeführt, so ist es zweckmäßig, wenn die Bleche in an sich bekannter Weise zwischen jedem Walzschritt auf eine Walzanfangstemperatur erwärmt werden.The Rolling of the sheets may, if necessary, in several rolling passes carried out be especially thin, to produce wide sheets. If a multi-stage rolling is performed, so it is useful if the sheets in a conventional manner between each rolling step be heated to a rolling start temperature.
Nachfolgend wird die Erfindung anhand einer ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert. Es zeigen:following the invention will be described with reference to an exemplary embodiment Drawing closer explained. Show it:
