Melting& Casting |
|
Various raws material (Copper, Zinc, Nickel, Aluminum and other alloying metals) are melted and then casted to rectangular slabs. |
|
|
|
|
|
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. |
|
|
Hot rolling in high temperature will create oxide scale. These unwanted scales are removed by scalping process, using cutter to cut out coil surface. |
|
|
4. |
|
|
Cold rolling reduces strip thickness. |
|
|
5. |
|
|
The strip which under gone cold rolling will be work hardened and will loose ductility. The work stress will be eased by heating to recrystalize grain structure in annealing process. |
|
|
6. |
|
|
Pickling process use acid & brush to remove oxidation scales from annealing. |
|
|
7. |
|
|
Final rolling require precise thickness and strip shape control. Latest technology enables to deliver superior product quality. |
|
|
8. |
|
|
Strip shape is adjusted by using tension levelling. |
|
|
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. |
|
|
Product is carefully inspected prior to packing and labelling. |
