FIELD: rolling.
SUBSTANCE: group of inventions relates to the field of rolling production and can be used to control a group of rolling stands through which a rolled metal strip passes sequentially. The method includes activation by means of a control device of executive links to regulate the contour of the roll gap of the subsequent rolling stand and the preceding rolling stand, while for the links of the preceding stand, regulatory signals are generated based on the determined change in the flatness of the strip behind the subsequent stand and with additional consideration for the determined change in the contour of the strip behind the subsequent cage, and for the links of the subsequent rolling stand, regulatory signals are formed based on the determined change in the contour of the strip behind the subsequent rolling stand, without taking into account the change in the flatness of the strip. Regulatory signals to the executive links of the subsequent rolling stand are applied with a delay during the transportation of the strip between the preceding and subsequent rolling stand.
EFFECT: use of the group of inventions makes it possible to expand processing capabilities and simplify the configuration of equipment.
