<p>PROBLEM TO BE SOLVED: Not to induce fluctuation of the rolling force difference on the drive side and operation side by imparting additive correcting/adjusting value which is formed from the horizontal rolling force which is measured in all individual rolls to the adjusting part. SOLUTION: Before processing flat products, the additive correcting/adjusting value which is formed from the horizontal rolling force measured in all individual rolls is imparted to the adjusting part. In such a case, by referring to the rolling force difference corrected by utilizing cross module for adjusting the variation, the conture of roll gap is maintained at constant over the whole width of a strip regardless of the position of the strip and distribution of rolling force. Furthermore, to change the dimensions of caliber after changing rolls, compensated rolling force difference is adjusted to zero after assemblying the rolls. By measuring the rolling force in the axial direction of the roll, an individual couple of force is determined. The rolling force difference generated from the total sum of these couples of force is calculated on-line.</p> |
