Description
Die
Erfindung betrifft ein Verfahren zum flexiblen Walzen von Metallband
oder Metallplatinen, wobei das Metallband oder die Metallplatinen
in Längsrichtung
des Walzvorgangs über
die gesamte Länge
von einer Ausgangsdicke auf eine veränderliche Enddicke ausgewalzt
wird. Ein Verfahren dieser Art ist aus der
Aus der Benennung einer Rekristallisationstemperatur von oberhalb 700° wird deutlich, daß als Ausgangsmaterial legierte Stähle anzunehmen sind.Out the name of a recrystallization temperature of above 700 ° becomes clear as starting material alloyed steels are to be accepted.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, das Anwendungsgebiet des genannten Verfahrens zu erweitern und insbesondere das Verfahren an ausgewählte Werkstoffe besonders anzupassen.Of the The present invention is based on the object, the field of application of the said method, and in particular the method to selected Especially adapt materials.
Die Lösung hierfür besteht darin, daß als Band- oder Platinenmaterial Leichtmetalle einschließlich ihrer Legierungen, insbesondere Aluminium oder Magnesium verwendet werden. Hiermit findet das sogenannte flexible Walzen auf Materialien Anwendung, die bisher aufgrund ihres günstigen Gewichts beim flexiblen Walzen unberücksichtigt geblieben sind. Mit den erfindungsgemäßen Verfahrenserzeugnissen kann beispielsweise die Gewichts- und Festigkeitsoptimierung im Fahrzeugbau noch weiter vorangetrieben werden, als es durch den einfachen Einsatz von Aluminium- oder Magnesiumblechbauteilen mit konstanter Dicke bisher möglich war.The solution therefor is that as band or board material light metals including their alloys, in particular Aluminum or magnesium can be used. Herewith finds the so-called flexible rollers on materials application, previously due to their Great Weight have been disregarded during flexible rolling. With the process products according to the invention For example, weight and strength optimization in Vehicle construction will be pushed even further than it is by the easy use of aluminum or magnesium sheet metal parts with constant thickness previously possible was.
Bei der Verwendung von Aluminium als Band- oder Platinenmaterial werden die folgenden Parameter als besonders günstig benannt: beim Walzen wird die Dicke um mindestens 5 % reduziert; die Enddickenunterschiede sollen mindestens 20 % betragen; das Material kann kaltgewalzt werden oder zum Warmwalzen auf eine Temperatur zwischen 350 und 470°C erwärmt werden; schließlich sollen die Dickenänderungen der Enddicke jeweils Gradienten von höchstens 1:40 aufweisen.at the use of aluminum as a tape or board material the following parameters are named as particularly favorable: when rolling the thickness is reduced by at least 5%; the final thickness differences should be at least 20%; The material can be cold rolled or heated to a temperature between 350 and 470 ° C for hot rolling; after all should the thickness changes each of the final thickness has gradients of at most 1:40.
Bei der Verwendung von Magnesium als Band- oder Platinenmaterial werden die folgenden Parameter als besonders günstig benannt: beim Walzen wird die Dicke um mindestens 5 % reduziert; die Enddickenunterschiede sollen mindestens 10 % betragen; das Material soll zum Warmwalzen auf eine Temperatur zwischen 180 und 280°C erwärmt werden; schließlich sollen die Dickenänderungen der Enddicke jeweils Gradienten von höchstens 1:40 aufweisen.at the use of magnesium as tape or board material the following parameters are named as particularly favorable: when rolling the thickness is reduced by at least 5%; the final thickness differences should be at least 10%; The material should be hot rolled be heated to a temperature between 180 and 280 ° C; finally should the thickness changes each of the final thickness has gradients of at most 1:40.
Beim Warmwalzen kann das Vorwärmen des Bandmaterials am aufgewickelten Coil erfolgen. Es ist jedoch auch die Erwärmung von abgewickeltem Bank in einem Durchlaufverfahren, insbesondere die induktive Erwärmung möglich.At the Hot rolling can preheat the strip material on the wound coil done. However, it is also the warming from settled bank in a continuous process, in particular inductive heating possible.
Das
flexibel gewalzte Material kann abgelängt oder beschnitten werden
und auf unterschiedliche Weise weiterverarbeitet werden und verschiedenen
Verwendungen zugeführt
werden. Es wird zunächst

Beispiele für die Veränderungen am Band- oder Platinenmaterial beim Walzen sind in den Zeichnungen verdeutlicht.Examples for the changes on the belt or board material during rolling are in the drawings clarified.
