Pfupiso yeCold Rolled Steel Coil
Coil inotonhorera inogadzirwa necoil inotonhorera inodziya. Mukuita kwecold rolled, coil inotonhorera inodziya inodzika pasi pekupisa kwe recrystallization, uye simbi inotonhorera inodziya patembiricha yemumba. Sheet resimbi rine silicon yakawanda harina kusimba zvakanyanya uye plasticity yakaderera, uye rinofanira kupiswa kusvika 200 °C risati raita cold roll. Sezvo coil inotonhorera isingapisi panguva yekugadzira, hapana zvikanganiso zvakaita se pitting ne iron oxide zvinowanzoonekwa mu hot rolling, uye kunaka kwepamusoro uye kupedzisa zvakanaka.

Giredhi reCoil rakaputirwa nechando
1. Chiratidzo cheChinese Nhamba Q195, Q215, Q235, Q275——Q—kodhi yenzvimbo yekukohwa (muganho) wesimbi yakajairika yekabhoni, inova ndiyo alphabet yekutanga yefonetiki yeChinese ye "Qu"; 195, 215, 235, 255, 275 - inomiririra kukosha kwenzvimbo yavo yekukohwa (muganho), iyo unit: MPa MPa (N / mm2); nekuda kwehunhu hwakazara hwesimbi yeQ235, plasticity, kuomarara uye weldability musimbi yakajairika yekabhoni. Kunyanya, inogona kusangana zviri nani nezvinodiwa zvekushandisa, saka chiyero chekushandisa chakafara kwazvo.
2. Chiratidzo chekuJapan cheSPCC - Simbi, P-Plate, C-cold, C-common yechina.
3. Giredhi reGermany ST12 - ST-simbi (Simbi), jira resimbi rinomonererwa nechando rine mazinga gumi nemaviri.
Kushandiswa kweCold Rolled Steel Coil
Coil inomonerwa nechando ine mashandiro akanaka, kureva kuti, kuburikidza nekumonerwa nechando, strip inomonerwa nechando nesimbi ine ukobvu hwakatetepa uye kunyatsoita zvakanaka zvinogona kuwanikwa, ine kutwasuka kwakanyanya, kutsvedzerera kwepamusoro, pepa rinomonerwa nechando rakachena uye rakajeka, uye kuputira kuri nyore. Kugadziriswa kwakapetwa, mhando dzakasiyana, kushandiswa kwakafara, uye hunhu hwekushanda kwepamusoro uye kusachembera, poindi shoma yekukohwa, saka pepa rinomonerwa nechando rine mashandisirwo akasiyana-siyana, anonyanya kushandiswa mumotokari, madhiramu esimbi akadhindwa, kuvaka, zvinhu zvekuvaka, mabhasikoro, nezvimwewo. Indasitiri iyi ndiyo sarudzo yakanakisa yekugadzira machira esimbi akamonerwa neorganic.
