FIELD: electricity.
SUBSTANCE: in method for controlling looper electric drive while filling a band in stand of finishing mill group of hot rolling the existence of static load on looper roller in its initial rise and, consequently, the fact that roller contacts with band is defined by change in looper frames motion acceleration, comparing it with the estimated one.
EFFECT: increasing the performance of electric drive throughout the entire range of looper elevation changes and thereby reduction of the likelihood of an emergency when filling a band in stand of finishing mill group of hot rolling.
