Process and plant for cold rolling with compensation for ovalization of the rolling rolls |
摘要 |
A process for the cold rolling of a metal strip between rollers of rolling stands arranged sequentially is provided, along with a plant for its implementation, wherein the process involves: analyzing, as a function of frequency, a signal from an inter-stand tension measurement sensor corresponding to a level of tension of the metal strip to determine periodic variations in the signal having frequencies corresponding to a speed of rotation of the pair of rollers in a downstream rolling stand and proportional to out-of-roundness defects present in the rollers of the downstream rolling stand; and compensating for the out-of-roundness defects in the rollers in the downstream rolling stand by adjusting the clamping setting of the rollers in the downstream rolling stand in accordance with a compensation signal, produced by the means for compensating, that is proportional to the periodic variations.
