Va'aiga lautele o Cold Rolled Steel Coil
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.

Fa'aogaina o le Cold Rolled Steel Coil
O le uʻamea faʻafefete malulu e lelei le faʻatinoga, o lona uiga, e ala i le taʻavale malulu, taʻavale malulu ma le uʻamea uʻamea ma le mafiafia manifinifi ma le maualuga maualuga e mafai ona maua, faʻatasi ai ma le saʻo maualuga, maualuga le lamolemole, mama ma susulu o le laupepa malulu. , ma faʻapipiʻi faigofie. O le gaosiga faʻapipiʻiina, ituaiga, faʻaoga lautele, ma uiga o le maualuga o le faʻailoga ma le le matua, maualalo le fua, o le mea lea o loʻo i ai le tele o mea faʻaoga, e masani ona faʻaaogaina i taavale, lolomi uʻamea, fausiaina, mea faufale, uila vilivae, ma isi. O le alamanuia o le filifiliga sili foi lea mo le gaosiga o laupepa uʻamea faʻapipiʻiina oona.
