摘要

The invention relates to a method and device for controlling the final thickness of a rolled product (b) at a tandem rolling mill exit which make it possible to remove the cyclic defects of the product thickness variation. The inventive method consists in using at least one rolling stand (4) provided with hydraulic adjustment means (45) located on the tandem rolling mill exit and in compensating the cyclic defects of the product thickness variation generated upstream through the entire rolling mill on said stand with the aid of an adjuster (R) co-ordinated with the frequency of defects. Said invention is particularly suitable for tandem cold rolling mills producing metal strips. According to said method, the thickness defects are detectable by means of a thickness sensor (J5). A device and arrangement for carrying out said method are also disclosed.
