<p>PROBLEM TO BE SOLVED: To enhance rolling efficiency by making the operation amount of each stand small, and the possibility of reaching an upper limit of a speed of each stand low, and eliminating the unnecessary speed limit. SOLUTION: By dividing the speed output for controlling the plate thickness into a plurality of the stands, and manipulating the roll speed of both stands of a (N-1)-th stand and a N-th stand, the delivery side plate thickness of the N-th stand is controlled to the target value.</p> |
