1. Melting & Casting
Various raw materials (Copper, Zinc, Nickel, Aluminum and other metals) are melted and then casted to rectangular slabs.
|
|
2. Slab Heating & Hot Rolling
The slabs are heated so that the metal slab is soft enough for hot rolling. The hot rolled plate is coiled for easier handling.
|
|
3. Scalping
Hot rolling in high temperature creates oxide scale. These unwanted scales are removed by scalping process, using cutter to shave away oxidized coil surface.
|
|
4. Rough Rolling
Rough rolling intensively reduces strip thickness.
|
|
5. Annealing
The strip which undergone rough and cold rollings is hardened and lost ductility. The work stress is eased by heating to have re-crystallized grain structure in annealing process.
|
|
6. Pickling
Pickling process uses acid & brush to remove oxidation scales from annealing.
|
|
7. Finish rolling
Final rolling requires precise thickness and strip shape control. Latest technology enables to deliver superior product quality.
|
|
8. Tension Levelling
Strip shape is adjusted by using tension levelling machine.
|
|
9. Slitting
Strip which went through various production process to meet mechanical properties requirements will be finally slitted to required sizes width and length wise.
|
|
10. Packing
Product is carefully inspected prior to packing and labeling.
