Abstract

The method concerns operation of a mill for hot and cold rolling of flat products in single or multiple arrangements of roll stands with two or more rolls. Control of the roll gap takes place with correction of the force difference between the roll drive and operator ends, and compensation of the settings correcting the bending and balancing forces. The method is characterised by the fact that the control system has an additional corrective quantity formed through measurement of the horizontal forces on all individual rolls.
