FIELD: technological processes.
SUBSTANCE: method involves working roll change tearing, strip and pinch rolling by rolls with given side microgeometry. Stripe surface processing is improved by rolling of bright finish strip steel after obtaining 300...310 tons of flat finish metal off new rolls with side microasperity height Ra=3.0...3.5 mcm, and pinch rolling is performed by polished rolls with Ra≤1 mcm.
EFFECT: improved consumer properties of cold-rolled thin sheet steel with given surface finishing.
