Abstract (en)
A duplex cold rolling line (1) includes a feeding unit (2), a first rolling unit (3), a furnace and descalingunit (4), apicklingunit (5), a second rolling unit (7) and an exit unit (8). The feeding unit (2) is adapted to unroll a hot-rolled coil to form an unrolled steel strip. The first rolling unit (3) includes at least two juxtaposed first rolling machines (31) adapted to perform a first-pass rolling operation on the unrolled steel strip. The furnace and descaling unit (4) is adapted to perform an annealing and descaling operation on the unrolled steel strip after completion of the first-pass rolling operation. The pickling unit (5) is adapted to perform a pickling operation on the unrolled steel strip after completion of the annealing and descaling operation. The second rolling unit (7) includes five juxtaposed second rolling machines (71) adapted to perform a second-pass rolling operation on the unrolled steel strip. The exit unit (8) is adapted to roll the unrolled steel strip to form a cold-rolled coil.
