摘要： In a method and system for controlling a final thickness of a strip material being rolled in a single-stand/multi-pass rolling mill having an adjustable main parameter affecting the final thickness and one or more auxiliary parameters affecting an intermediate thickness, the reference value of the main parameter is corrected in accordance with the deviation of the final thickness from its reference value and a reference value of at least one of the auxiliary parameters is corrected to cancel the effect of the correction to the main parameter on the intermediate thickness.

摘要： A multi-pass rolling method and a multi-pass rolling-mill stand best adapted to carry out said multi-pass rolling method. In a rolling-mill stand having three or more work rolls arranged one above the other, a workpiece is simultaneously rolled at two or more points by at least one of the work rolls.

摘要： A multi-pass rolling method which permits a multi-pass rolling-mill stand to perform multi-path rolling and still stabilize the rolling operation by preventing lateral deviation movement of a metal workpiece being rolled. The rolling-mill stand has three or more work rolls arranged one above the other and the workpiece is simultaneously rolled at two or more points by at least one of the work rolls. Directly or indirectly roll gaps are detected on the work and drive sides of at least one pass by sensors. A difference signal from the output signals of the sensors is obtained thereby determining a roll gap difference. Control devices are provided which are responsive to the difference signal for independently changing the roll gaps on the work and drive sides.
