Abstract
A method and device for controlling the final thickness of a rolled product at a tandem rolling mill exit which make it possible to remove the cyclic defects of the product thickness variation. The method includes using at least one rolling stand provided with hydraulic adjustment devices 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 the stand with the aid of an adjuster (R) coordinated with the frequency of defects. The method and device are suitable for tandem cold rolling mills producing metal strips. The thickness defects are detectable by a thickness sensor.
