By linking the existing No.1 pickling line and No.1 cold rolling mill together, this two lines had been modified to become a continuous operation pickling and cold rolling mill in 1998. Hot rolled coils are charged into two pay off reels on the entry side of pickling area. They are welded, levelled, pickled, cold rolled and become cold rolled coils. Features are tension levelling and scale breaking before pickling, hydrochloric acid pickling, three turning devices, work roll shift, and shape control.
