III.  Process Process Flow

Major equipments in turns are as follows:
Crane hoisting coils to skids →coil laoding car→ decoiler (pressure roller,
anti-curve roller) → decoiling scraper → Deflector roll → vertical
guide roller → pinch roller straightener → crop shearer →corner
shearer(with scrap bucket) → vertical guide roller → pre-washing
trough → four-grade hydrochloric acid pickling trough → four-grade
washing trough (Including pre-washing section) → edge blowing device
→ hot air dryer → II# pinch roller → looper (Both ends are equipped
with looper swing stand) → vertical guide roller → pinch centering
machine → circle shearer (With waste edge recoiler) → 3-roller
tension roller → crosscut shearer → vertical guide roller → steering
pinch roller → recoiler → coil unloading trolley → coil receiving stand
→Crane hoisting coils to storage house
