<p>PURPOSE:To quickly suppress the variation of a loop due to disturbance and the change of set value without executing the excessive operation of individual rolling mill. CONSTITUTION:A material is moved while being successively rolled with plural- stage rolling mills including a pivot rolling mill and also a loop is held between the rolling mills. To suppress the influence on the other loops by operating the means such as a loop detector 16 and controllers 21, 22 for operating the speeds of both rolling mills 4, 5 which are situated before and behind the loop 11 in which the deviation between the set value and detected value of the amount of loop is detected and the rolling mills 4, 5, and controllers 19, 20, 23, 24 are provided, with which the equal operations are mutually executed about the speeds of the rolling mills 2, 3 on the anti-pivot side and operation such as the degree is gradually decreased as the position is apart from the loop 11 is executed about the speeds of the rolling mills 6, 7 on the pivot side.</p> |
