Abstract (en)
A method for continuously manufacturing cold-rolled steel includes the steps of: providing coils (100) of white steel (400) that are manufactured by hot rolling a cast steel followed by annealing and pickling the cast steel; subjecting the coil (100) of white steel (400) to uncoiling and welding in an uncoiling-welding installation (21); passing the flattened and welded white steel (400) through a first strip accumulator (22) and a cold rolling device (23) for cold rolling the white steel (400) to result in a cold-rolled steel with a predetermined thickness; and processing the cold-rolled steel in sequence using a degreasing device (24), a second strip accumulator (25), an annealing-pickling installation (26), a third strip accumulator (27), a temper rolling device (28), a tension leveling device (29), a fourth strip accumulator (31), and a trimming-recoiling installation (32).
