FIELD: metallurgy.SUBSTANCE: method includes passage of metal strip through pickling line and then between two reversing reels through reversing rolling mill. The end of one metal strip before pickling line is welded to the beginning of the next metal strip. Before reeling of finally rolled metal strip, metal strips welded to each other are separated. Reduction of time intervals for change of coils and deviation of nominal dimensions of the strip is provided due to the fact that the metal strip A, coming out of the pickling line, passes both rolling mills (3, 4) of reversing rolling mill. To the end of metal strip A before delivery to pickling line (5) the beginning of the next metal strip B is welded. This beginning of the metal strip B is also rolled to the length corresponding to the length of reeling till tension on the reel is achieved, and also the beginning overlaps the reversing reel (1). During the next reversing, metal strip B is separated from the metal strip A so that the rolled beginning of the metal strip B is left with non-rolled steel metal strip B. Then reversing rolling is performed on all the metal strip A.EFFECT: higher production quality.3 cl, 6 dwg |
