Va'aiga mafiafia: 0.1mm-0.45mm

lautele lautele: 700mm-1000mm

Mea: SPCC, SPCC, SPCD, SPCE, DC01, St12, DC03, St13, DC04, St14, Q235, St37-2G, S215G, JG300LA, JG340LA

Fa'aaliga: Talu ai e le fa'apipi'iina, o lona ma'a'a e maualuga tele (HRB e sili atu nai lo le 90), ma o le fa'aogaina o masini e matua leaga lava. E na'o se faiga fa'apipi'i fa'ata'ita'i faigofie e itiiti ifo i le 90 tikeri (tutusa i le itu fa'a'ai'oi) e mafai ona fa'atino. O nisi u'amea u'amea e mafai ona gaosia fa'aulu.

Va'aiga lautele o le u'amea taai malulu

O le u'amea taai malulu e faia i le u'amea vevela. I le faagasologa o loʻo faʻafefeteina, o loʻo taʻavale le vevela vevela i lalo ifo o le vevela recrystallization, ma o le uʻamea masani e taʻavale i le vevela o le potu. Pepa u'amea fa'atasi ai ma mea e maua i le silikoni maualuga e maualalo le ma'ale'ale ma le palasitika maualalo, ma e mana'omia ona fa'amumu i le 200 °C a'o le'i ta'avale malulu. Talu ai e le faʻamafanafanaina le faʻamalo malulu i le faagasologa o le gaosiga, e leai ni faaletonu e pei o le pitting ma le uʻamea uʻamea lea e masani ona maua i le vevela vevela, ma o le maualuga o le maualuga ma le maeʻa e lelei.

Cold Rolled Coil Production Process

O le taʻavale malulu malulu e faia i le vevela vevela, ma o lona gaosiga faʻagasologa e masani lava ona ui atu i faiga autu e pei o le sauniuniga o mea mataʻutia, malulu malulu, togafitiga vevela, faʻavasegaina ma faʻamaeʻaina.

Cold Rolled Coil Fa'atinoga o oloa

O le lola ma le laulau e toetoe lava o se afifi tipi. O le vili malulu e maua mai i le pikiina ma le malulu o le ta'avale vevela. E mafai ona taʻua o se ituaiga o vili taai malulu. Cold rolled coil (annealed state): E maua le u'amea vevela e ala i le pikiina, ta'avale malulu, fa'afefeteina o le pulou, fa'ata'atia, (fa'auma).

E 3 le eseesega tele i le va oi latou:

I foliga vaaia, o le coil malulu lautele e fai si fa'ase'e.

Pepa ta'ai malulu e pei o le lelei o luga, fausaga ma le sa'o sa'o e sili atu nai lo coils malulu.

I le tulaga o le faatinoga, o le coil malulu na maua saʻo pe a maeʻa le faagasologa o le taʻavale malulu o le vili vevela o loʻo galue malosi i le taimi o le taʻavale malulu, e mafua ai le faʻateleina o le malosi o le gaosiga ma se vaega o le faʻalavelave i totonu o loʻo totoe, ma o foliga i fafo e fai lava si "faigata. ". E ta'ua o le coil malulu.

O le mea lea, o le malosi e maua ai: o le uʻamea malulu e sili atu nai lo le faʻafefete faʻafefete (tulaga faʻafefete), ina ia sili atu ona lelei le faʻafefeteina o le malulu (state annealed). E masani lava, o le tulaga le maua o le tu'uina atu o coils taai malulu ua annealed.
