FIELD: metallurgy.
SUBSTANCE: invention relates to ferrous metallurgy field. Particularly it relates to manufacturing of rolled iron, and can be used in manufacturing of strip low-carbon steel for polymeric coating. For this technical result achieving it is implemented continuous casting from aluminium-killed low-carbon steel into slabs, strip hot rolling and its winding into rolls, etching, cold rolling till thickness 0.17-0.50 mm, electrolytic degreasing, recrystallisation continuous annealing, temper rolling and deposition of coating, herewith hot rolling is finished at the temperature 860-910°C, strips winding into rolls is implemented at the temperature 700-750°C, and recrystallisation continuous annealing is implemented in the range of temperature from 630 till 700°C, then it is implemented strip temper rolling with cobbing from 0.35 till 0.80%.
EFFECT: plastic properties increasing of strips and coating strength increasing.
