FIELD: metallurgy.
SUBSTANCE: invention refers to metal forming, particularly to production of cold rolled IF steel containing 0.006 wt % of carbon, and also titanium and niobium. Hot rolling is commenced at 1150-1180°C temperature and is finished at 870-900°C temperature. Winding of hot rolled bands is performed at 700-740°C. Cold rolling is carried out with total reduction of 66-70%. Further pinch rolling is executed with reduction of 0.4-0.6% in notched rollers of micro-geometry Ra=3.0-3.5 mcm and with amount of peaks of roughness not less, than 50 per 1 cm.
EFFECT: increased output of qualitative cold rolled sheet steel suitable for deep stamping.
