Abstract

Die Erfindung betrifft ein Verfahren zum Herstellen von warmgewalztem Stahlband aus einem bandförmig strang­ gegossenem Vormaterial, bei dem das Vormaterial nach Erstarrung in ein mit möglichst hoher Stichabnahme verformendes kontinuierliches Walzwerk eingeführt wird, dessen Walzensätze mit minimalen Abstand hintereinander angeordnet sind. Um ein Verfahren und eine Vorrichtung des Verfahrens zu schaffen, mit dem bzw. der es möglich ist, eine maximale Stichabnahme in minimalen Walzstichen durch-zuführen, wird vorgeschlagen, daß das Vorband mindestens in zwei aufeinanderfolgenden Walzensätzen unter geregeltem Zug reduziert wird. The invention relates to a method for producing hot-rolled steel strip from a strip-like strand cast primary material, in which the primary material after Solidification into one with the highest possible decrease in stitch deforming continuous rolling mill is introduced, its roller sets with a minimal distance behind each other are arranged. To a method and an apparatus of the process by which it is possible is a maximum stitch decrease in minimum roll passes it is proposed that the opening act at least in two successive roller sets is reduced under controlled tension.
