FIELD: continuous rolling mills.
SUBSTANCE: work of the support roll is alternated for each stands of the mill in contact with the adjacent work roll with regrinding to remove the damaged layer. The amount of removal during regrinding of the support roll after the rolling campaign is regulated depending on the number of its stand of the mill based on the coefficients determined by the ratio of the length of the rolled strip and the average linear load in the roll contact, in the considered stand and the most loaded stand of the continuous wide-strip mill.
EFFECT: consumption coefficient of backup rolls decreases and the operating time of their working layer increases.
