FIELD: rolling process; making coiled thin-sheet cold-rolled steel.
SUBSTANCE: proposed method includes rolling the strips, 0.6-2.0 mm wide at reduction of specific tension and increase of thickness of strip in rolls at surface roughness of their barrels Ra=0.71.2 mcm; then, coils are subjected to annealing and are kept under hood with burners disconnected for 12 hours at mass of coils Q³15 t and for 8 hours at mass of coils Q<15 t.
EFFECT: improved properties of coiled steel at rolling in reversible mill.
