Abstract (en)

[origin: CA2182832A1] A method of compensating forces of force components resulting from horizontal movements of the rolls in roll stands for hotrolling and cold-rolling of flat products, wherein the roll stands are equipped with work rolls and with one or more back-up rolls, with hydraulic adjusting units and with force measuring devices on the opposite side of the roll gap and with hydraulic devices for the horizontal displacement of the work rolls. The pressures in the two adjusting cylinders are utilized for determining the rolling forces on one side of the roll gap and the forces indicated by the force measuring devices are utilized for determining the rolling forces on the opposite side of the roll gap, and all axial forces in the stand are computed during the rolling operation by including the axial forces of the work rolls which can be determined through the pressures in the displacement cylinders of the work rolls.
