<p>PURPOSE: To perform cold rolling on a metallic strip of which edge drop quantity is different at both end edges by eliminating and correcting meandering. CONSTITUTION: In a strip rolling mill which enables upper and lower work rolls 2, 3 to be shifted in reverse to each other in the axial direction, an edge drop quantity is measured at both end edges with an edge drop measuring device 5; the shift distance of the upper and lower work rolls 2, 3 is calculated for the purpose of correcting the edge drop quantity with a control computer 6; flow control valves 9, 10 are controlled to shift cylinders 7, 8 and a speed is controlled so that the shift time is equalized between the upper and lower work rolls 2, 3.</p> |
