Cold rolled steel isimbi inogadzirwa nechando.Cold rolling isimbi yesimbi inowanikwa nekuwedzera kuderedza Nha.Kuenzaniswa nesimbi inopisa-yakakungurutswa, simbi inotonhora ine hupamhi hwepamusoro, yakatsetseka uye yakanaka nzvimbo, uye inewo akasiyana emhando yepamusoro michina, kunyanya maererano nekugadzirisa.Nekuda kwekuti makoiri anotonhora akakungurutswa ane brittle uye akaomarara, haana kukodzera kugadzikiswa, uye machira anotonhora akakungurutswa anowanzoda kuvharwa, kunyungudutswa uye kukwenenzverwa pamusoro asati aendeswa kune vatengi.Ukobvu hwepamusoro hwekukunguruka kunotonhora huri pasi pe0.1–8.0MM.Semuenzaniso, ukobvu hwesimbi inotonhora-yakakungurutswa ndiro mumafekitari mazhinji iri pasi pe4.5MM;hushoma hukobvu nehupamhi hunotarwa zvichienderana nehukuru hwemidziyo uye kudiwa kwemusika kwefekitori yega yega.
Musiyano pakati pesimbi inotonhora uye inopisa-yakaputirwa simbi haisi iyo yekunyungudutsa, asi tembiricha yekukunguruka, kana tembiricha yekupedzisira yekukunguruka.Cold rolled steel zvinoreva kuti tembiricha yekupedzisa yakaderera pane tembiricha recrystallization yesimbi.Simbi inopisa-yakaputirwa iri nyore kukungurusa uye ine kukwirira kwepamusoro-soro, asi pasi pemamiriro ekupisa-akatenderedzwa, simbi ine oxidized uye pamusoro pechigadzirwa chakasviba grey.Simbi inotonhora-yakakungurutswa inoda simba reguyo repamusoro uye kudzika kwakadzika.Yepakati annealing inodiwa kubvisa kuomeswa kwebasa panguva yekukungurutsa, saka mutengo wakakwira zvakare.Zvisinei, simbi inotonhora ine nzvimbo yakajeka uye yakanaka, uye inogona kushandiswa zvakananga kugadzirisa.zvigadzirwa zvakapedzwa, saka simbi inotonhora yakatenderedzwa mashizha anoshandiswa zvakanyanya.
Iyo inopisa-yakaputirwa simbi coil inoshandiswa seyakaomeswa, mushure mekutora kubvisa iyo oxide chiyero, inotonhora inoenderera ichitenderedzwa inoitwa, uye iyo yakaoma coil inokungurutswa.Kutonhora kushanda kuomarara kunokonzerwa nekuenderera kutonhora deformation kunowedzera simba, kuoma, kuomarara uye indekisi yepurasitiki yemakoiri akaomarara., saka kuita kwekutsika kuchave kwakashata, uye kunogona kushandiswa chete kune zvikamu zvine deformation iri nyore.Makoiri akaumburudzwa akaomarara anogona kushandiswa seyakabikwa muzvirimwa zvinopisa dip galvanizing nekuti mitsetse yekunyungudutsa yedip inopisa ine mitsara yekumisikidza.Huremu hweiyo coil yakaoma yakatenderedzwa kazhinji 6 ~ 13.5 matani, uye inopisa-yakakungurutswa yakanyungudutswa coil inogara yakakungurutswa pakamuri tembiricha.Iyo dhayamita yemukati ndeye 610mm.
