CONTROL OVER ROLLING MILL Russian patent published in 2016 - IPC B21B37/28 

FIELD: process engineering.

SUBSTANCE: invention relates to metallurgy. Temperature (T) is defined for strip sections (6) ahead of the first rolling mill stand (2) while time horizon (PH1) is used to predict said temperature for appropriate rolling time interval. Said time horizon (PH1) corresponds to several sections (6) of the strip. Temperatures (T') are used to predict the material modules (M) on the sides of servicing and drive. Actuator (10) arranged on the side of servicing and drive can influence the deformation source of the first rolling stand (2). Control over device (10) during rolling of appropriate strip section (6 is executed with due allowance for material modules (M). Material modules (M) are used the in actuator (10) at the time interval of rolling of strip appropriate section (6) at the rolling stand (2) for determination of parameters of the deformation source control (20) on the servicing and drive sides. For the first time horizon (PH1) used is the pattern of variation (S(t)) in the control variable for actuator (10) which influences the profile of deformation source created by rolling stand (2) rollers (9). Predicted temperatures (T') and said control variable variation pattern (S(t)) are used to predict the deformation source profile (W) for time horizon (PH1) created by rolling stand (2) rollers (9) at rolling of the strip section (6).

EFFECT: higher quality of strip.
