FIELD: metallurgy.
SUBSTANCE: method includes hot rolling and strip winding. It is regulated retarded cooling with temperature equalisation of coils by section of coil is provided ensured by coating of liquid heat-insulating material by fine-dispersed spraying on surface of strip in the winding process. For steels with poor heat conducting heat-insulating material is coated on surfaces of end strips section, equal to 1…5 perimetre of circle of the first coil layers in the beginning of winding and 1…7 perimetre of circle of the last ready coil layers in the end of winding.
EFFECT: increasing of structure uniformity and mechanical properties lengthwise black strip during its manufacturing on broad-strip mill and winding into coil.
