FIELD: metallurgy.
SUBSTANCE: method includes billet heating, rolling in work rollers with different diameter, and plastic bending by bending roller. Metal plates quality increases due to exclusion of variations of bend radius along its length by preliminary setting of length of face and rare billet sections equal to distance between axes of the bending roller and work rollers, these sections rolling is performed with offset angular speeds of the work rollers within range 1.0-20.0%.
EFFECT: method creates such deformed state when elongation of metal layers along the full length of the billet is similar.
