ABSTRACT:
In a rolling mill it is desirable that the torques delivered by the two driven rolls should be the same or at least there should be some predetermined torque differential between them. The torque transmitted by each of the driven rolls is measured and a measure of the difference between the torques is obtained. Said measure is then used to adjust the angular length of that part of the periphery of at least one roll where it is in contact with the workpiece being rolled in the sense to bring about the required torque distribution.
The angular length may be adjusted by varying the angle of approach or exit of the workpiece relative to the mill rolls.
