FIELD: automation of rolling processes.
SUBSTANCE: method comprises steps of measuring disturbance-stimulated strip thickness in front of rolling stand; controlling measurement result until inlet of stand; compensating it in stand by moving screws of screw-down mechanism at predetermined rate for preset time interval; measuring fluctuation of strip thickness relative to predetermined value when strip leaves stand; acting upon movement rate of screws according to disturbance and to fluctuation of strip thickness after multiplying said values and differentiating received product.
EFFECT: enhanced accuracy and reliability of controlling strip thickness.
