FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy and can be used in production of hot-rolled and hot-rolled etched rolled product with thickness of 3.0-6.0 mm, for making discs and rims of wheels by cold forming. Method involves melting steel, furnace treatment, continuous casting, heating of slab for hot rolling, rolling in roughing and finishing continuous groups of stands of broad-strip mill, cooling a strip with water at collecting roller table with further coiling into roll.
EFFECT: higher ductility and formability of rolled stock is ensured by specifying composition of steel, modes of rolling, heat treatment and reeling.
