FIELD: metallurgy.
SUBSTANCE: method consists in rolling strip of hot rolled stock in rollers of wide-strip mill to specified reduction. Production of sheet steel with properties of hard-drawn metal usable for successive galvanisation is achieved by rolling at two-stand reverse mill with relative total reduction within ranges 69…79 %; also value of reduction in a finish pass is accepted equal to 56…60 % from reduction in the first pass, while value of specific tension is accepted within ranges 75…85 H/mm2 with additional tension not more 20 H/mm2.
EFFECT: upgraded consumer properties of low carbon cold rolled sheet hard-drawn steel with section of 0,43…0,63×1250 mm.
