FIELD: metallurgy.
SUBSTANCE: method includes sequential cobbing of hot-rolled flat work of specified width. Flatness and ability for products die forming is provided ensured by strips cold rolling made of steel grades 08 rimmed, semikilled and "08Ю" for the finite thickness h is implemented in rollers of reversible two-stand mill from the work of thickness H, which at its width B=1030…1300 mm is equal: H=1.22h+1.36 mm, and at B=1301…1630 mm-H=1.05h+1.44, mm, herewith value of strip's specific tension on head of rolled coil of length about 1/3 of its total length is accepted equal to σk=69…71 N/mm2, and at its rest part σc=σk-20 N/mm2.
EFFECT: improvement of consumer properties of cold-rolled sheet mild steel.
