FIELD: production of steel sheets, namely skin pass rolling of coiled steel strips.
SUBSTANCE: method comprises steps of reducing strip between rolls of skin pass rolling mill; reducing near -edge portions of strip along thickness consisting 0.12 -0.16 of thickness of strips having thickness 0.2 - 1.0 mm and made of steel with yield limit σy = 350 MPa. Said near-edge portions are reduced at deformation degree ε exceeding deformation degree of their mean portion by value normalized by means of mathematical expression.
EFFECT: possibility for providing similar mechanical properties of metal along thickness of strip.
