ABSTRACT:
In descaling and cold rolling of metal strip, there are performed the steps of joining strips longitudinally together, passing the joined strip continuously through a descaler, subdividing the descaled strip into long strip lengths and coiling the long strip lengths into large coils at a first coiling station having a plurality of coiling drums, feeding the large coils from said coiling station to a cold rolling mill and rolling each of them in the mill. The cold rolling mill is a reversing multi-pass cold rolling mill in which the strip is rolled in a plurality of passes with reversal. To achieve efficient use of the capacity of the reversing mill while reducing the size of the descaler, coiling and uncoiling of two said large coils respectively take place simultaneously at the first coiling station, and each long strip length is coiled a first time on one of the coiling drums at the coiling station on exit from said descaler and at least a second time on the same coiling drum during its rolling in the mill. Apparatus for carrying out such a method is also described.
