FIELD: ferrous metallurgy, namely manufacture of coiled sheet metal in continuous and reversing cold rolling mills with further treatment of metal coils in hood furnaces and then rolling them in skin pass rolling mills.
SUBSTANCE: method comprises steps of cold rolling of strips at feeding lubricating and cooling liquid; coiling strips of predetermined final thickness; annealing coils in hood furnaces and skin pass rolling them. During stable process of cold rolling metal temperature along length of coiled strip of predetermined final thickness is lowered at coiling in such a way that to provide difference between temperature values of strip at starting coiling and at terminating it in range 5 - 100 C. Method allows to eliminate occurring of surface flaws of ready metal strips and sheets such as "fracture", "spots of sticking together-welding", "scratches", "notches".
EFFECT: lowered level of pressure between turns of coils.
