Abstract

Bei der Walzung von Metallband in einer Walzstraße, wobei ein Vorband bzw. eine Dünnbramme (14) in aufeinanderfolgenden Schritten zu einem Metallband ausgewalzt wird, ergeben sich häufig Walzfehler bei der Walzung des vorderen oder hinteren Endes (18) des Vorbandes bzw. der Dünnbramme (14). Diese Walzfehler (Bandendenverwalzung), die in Form einer unerwünschten Breitung oder einer Bandmittenabweichung auftreten, lassen sich gemäß der Erfindung dadurch vermeiden, dass vor dem Walzen entsprechend große Bereiche (4') des vorderen oder hinteren Endes (18) des Vorbandes bzw. der Dünnbramme (14) mit Hilfe einer Trennvorrichtung (30) während des Transportes des Vorbandes bzw. der Dünnbramme (14) abgetrennt werden.

Figure 00000001
When metal strip is rolled in a rolling mill, a preliminary strip or thin slab (14) being rolled out in successive steps to form a metal strip, rolling errors often occur when the front or rear end (18) of the preliminary strip or thin slab ( 14). These rolling defects (strip end rolling), which occur in the form of an undesirable spreading or a strip center deviation, can be avoided according to the invention in that correspondingly large areas (4 ') of the front or rear end (18) of the pre-strip or thin slab before rolling (14) with the aid of a separating device (30) during the transport of the preliminary strip or thin slab (14).
