FIELD: production of rolls of a given length.
SUBSTANCE: billet is rolled in roughing and finishing groups of stands and then rolled into a roll. Between the roughing and finishing groups of stands, the rolled stock is divided into segments of a given length. The rolling speed after the finishing group of stands is 1.5-25 times higher than the rolling speed after division. As a result, a decrease in the speed of movement of rolled products at the exit from the finishing group of stands is prevented and high-quality rolled products are made.
EFFECT: effective performance.
