  • the strip feeders arranged in front of the individual stand in the strip running direction compensate for the mass flow changes or strip speed changes caused by a change in the strip thickness or a change in the strip thickness profile during flexible rolling. This shows in particular the advantage that rolling with a changing strip thickness sequence is still possible even at higher rolling speeds.
  • the speed changes due to the change in the strip thickness in the roll gap are greatest on the entry side of the stand, so that the strip store is provided according to the invention at least in the entry area. Since the disturbances due to the change in the course of the strip thickness, i.e. In the case of a flexible roller, which also has - but not so strongly - an effect on the outlet-side belt speeds, it is proposed according to a preferred embodiment to also arrange a belt store on the outlet side of the individual stand.
  • the tape store is preferably a dancer role.
  • a dancer roll or a dancer roll arrangement comprises a roll which can be set at a certain angle with respect to the band and can be acted upon with a certain force, so that a loop is formed in the band, the loop length of which changes with the position of the roll. In this way, more or less tape can be stored.

Abstract

L'invention concerne un laminoir à froid et un procédé de laminage à froid d'une bande métallique (8), notamment d'une bande d'acier, composé d'une cage individuelle (1) comportant des moyens destinés à régler l'emprise, d'un dispositif de déroulage (9) logé en amont de la cage individuelle de laminoir à froid, destiné à dérouler la bande (8), et d'un dispositif d'enroulage (10) logé en aval de la cage individuelle de laminoir à froid (1), destiné à enrouler la bande (8). L'invention vise à éliminer tout problème lié à la tension de la bande dans le cas de variations de l'épaisseur de la bande, et à augmenter la vitesse de la bande. A cet effet, une bande accumulatrice est disposée entre le dispositif de déroulage (9) logé en amont et la cage individuelle (1), ladite bande servant à la régulation du flux massique et/ou à la régulation de la tension de la bande du processus de laminage, notamment dans le cas de cylindres flexibles.
