FIELD: metallurgy.
SUBSTANCE: invention relates to a rolling production. Control method comprises determining the linear speed of the strip and the strip thickness deviation from the set point at the entrance to the mill, and the impact of using a control strip thickness deviation of the position of the knob of the pressure device. Additionally, the linear speed of the strip is determined on the exit of the mill, and as a regulator of thickness tolerances using integral control. As the feedback control using the calculated signal predictive thickness deviation output directly in the deformation calculated by the mathematical expression.
EFFECT: technical result - increase the stability of rolling.
