Process Flow Chart for CRCA Product<br />

(Cold Rolled Sheet in <strong>Coil</strong> JISG 3141 SPCC � 1B/1D )<br />

Hot Rolled <strong>Coil</strong>s are used as input (raw materials) for manufacturing Cold Rolled Close Annealed<br />

(CRCA) product. Following thus, pickling and mill rolling is carried out followed by rewinding,<br />

annealing, Skin Pass, and Cold Rolled Slitting.<br />

Hot Rolled <strong>Coil</strong>s are pickled (Acid cleaning that removes Scale from the surface of the strip) and<br />

processed into cold rolled (reducing the thickness) sheets. Annealing is carried out in a closed<br />

atmosphere of hydrogen and/or other non-oxidizing gases. It softens the product back up whilst<br />

protecting it from oxidization.<br />

The product then goes through Skin Pass Mill (process of removing yield point elongation of<br />

Annealed sheet) for improving surface finish and flatness of the strip. In this phase, rust<br />

preventive oil is used and also the shape is controlled.<br />
