Abstract:
(EN) The invention relates to a method for cleaning rolling stock (5) during cold rolling of said rolling stock (5) in a tandem mill (1) which comprises a plurality of mill stands (7, 9). The rolling stock (5) is moved through the tandem mill (1) in a direction of movement (3) and a cleaning liquid (26) is sprayed onto the rolling stock (5) between two roll stands (7, 9) in a spraying direction having a component opposite to that of the direction of movement (3).
(FR) L'invention concerne un procédé pour nettoyer une matière à laminer (5) pendant le laminage à froid de cette matière à laminer (5) dans un train de laminoir en tandem (1) comportant plusieurs cages de laminoir (7, 9). La matière à laminer (5) est déplacée dans le train de laminoir en tandem (1) dans une direction de traitement (3), et un liquide de nettoyage (26) est pulvérisé sur la matière à laminer (5) entre deux cages de laminoir (7, 9) dans une direction de pulvérisation présentant une composante opposée à la direction de traitement (3).
(DE) Die Erfindung betrifft ein Verfahren zum Reinigen eines Walzguts (5) beim Kaltwalzen des Walzguts (5) in einer mehrere Walzgerüste (7, 9) aufweisenden Tandemstraße (1), wobei das Walzgut (5) in einer Durchlaufrichtung (3) durch die Tandemstraße (1) bewegt wird und zwischen zwei Walzgerüsten (7, 9) eine Reinigungsflüssigkeit (26) in einer Sprührichtung, die eine der Durchlaufrichtung (3) entgegengesetzte Komponente aufweist, auf das Walzgut (5) gesprüht wird.
