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. The invention relates to a method for manufacturing of sheet metal, which in its further processing a deep-drawing process and a coating process is subjected to cold rolling. Cold rolling is completed by skin - dressing and the Surface roughness of the thin sheet by means of a fine-grained inorganic abrasives roughened Skin pass rolls produced. There are skin pass rollers used, the ground surface with a Abrasive is blasted, which - after the Mohs hardness scale - a hardness of about 9 and above it.
