Abstract
Die Erfindung betrifft ein Verfahren zum Herstellen
von Feinblech, welches in seiner Weiterverarbeitung
einem Tiefziehvorgang und einem Beschichtungsvorgang
unterworfen wird, durch Kaltwalzen. Das Kaltwalzen
wird durch Dressieren abgeschlossen und dabei wird die
Oberflächenrauhigkeit des Feinbleches mittels mit einem
feinkörnigen anorganischen Strahlmittel aufgerauhter
Dressierwalzen erzeugt. Es werden dazu Dressierwalzen
verwendet, deren geschliffene Oberfläche mit einem
Strahlmittel gestrahlt wird, welches - nach der
Mohs'schen Härteskala - eine Härte von etwa 9 und
darüber aufweist.
