FIELD: metallurgy.
SUBSTANCE: in suppression method of impact of eccentricities of rolls on output thickness (ha) of rolled material (10) which is passed through rolling mill (1) the eccentricities of rolls are identified with use of model (27) of the process. Eccentricities of rolls are considered at determination of corrective signal at least for one control device (19) for actuating element, mainly actuating element for position of installation of rolling mill (1). At that, values of tension force (Fz) measured before the rolling mill are supplied for identification of eccentricities of rolls to model (27) of the process. According to the invention the fluctuations of tension force are purposefully supplied back to reduce the impact of periodic eccentricities of rolls on rolled material (10), while all the other sources of fluctuations are excluded.
EFFECT: higher rolling quality.
