Cold Rolled ma Cold Hard Coil

Cold Rolled ma Cold Hard Coil

Cold Hard coil e maua mai i le pikiina ma le ta'avale malulu o le u'amea vevela.O se ituaiga vili taai malulu.

Cold rolled coil (annealed state): Hot rolled coil through pickling, cold rolling, hood annealing, leveling, (uma), e mafai ona maua Cold rolled coil.

Le eseesega i le va o Cold Rolled ma Cold Hard:

1.From le foliga mai, malulu ipu Hard o se lanu Micro Black itiiti masani

2.The surface quality , Fauga ma le Fua saʻo o Cold Rolled e sili atu nai lo Cold Hard.

3. I le faatinoga:

Talu ai ona o le Cold Hard coil na maua saʻo mai i le faagasologa o le taʻavale malulu, i le faagasologa o le taʻavale malulu o loʻo galue malosi i le taimi o le taʻavale malulu, o le malosi o le gaosiga e faʻateleina ma o loʻo tumau pea le popole i totonu, ma o foliga i fafo e faigata tele, o lea e taʻua ai Cold Hard coil..

Cold-rolled coil (annealed state): e maua le u'amea malulu malulu e ala i le fa'aulu fa'aulu a'o le'i ta'avale.A maeʻa le faʻamaʻi, o le faʻamaʻaʻaina o galuega ma le faʻalavelave i totonu e faʻaumatia (matua faʻaitiitia), o lona uiga, o le malosi e maua mai e faʻaitiitia i le malulu.A'o le'i ta'avale.

O le mea lea, o le malosi e maua ai: o le malulu malulu malulu e sili atu nai lo le faʻafefete faʻafefete (tulaga faʻafefete), ina ia sili atu ona lelei le faʻamalo o le malulu (state annealed) mo le faʻailoga.
