Cold drawn seamless steel chubhumaitiro: kutenderera chubhu → kudziyisa → perforation → Musoro → kunhonga → kunhonga → mafuta (mhangura) → yakawanda-inopfuura inotonhora inodhonzwa (inotonhora yakakungurutswa) → isina chubhu → kupisa kupisa → kutwasanura → hydrostatic kuyedza (kuyedza ) → maka → chengetedzo.

Cold yakadhirowewa simbi chubhu ine inopisa-yakakungurutswa simbi coil seyakagadzirwa, uye tandem inotonhora inotenderedza yakanyungudutswa kuti ibvise oxide chiyero, iyo yakapedzwa kukungurukira yakaoma roll, kukungurutsa mavhoriyamu akaomarara nekuda kwekuenderera kutonhora deformation kunokonzerwa nekutonhora kuomesa simba, kuoma kwakawedzera zviratidzo kwakaderera. mapurasitiki akaoma, kutsika kwekuita kuchaderera, izvo zvinogona kungoshandiswa kune nyore deformation yezvikamu.Rolling hard roll inogona kushandiswa seyakabikwa yeiyo inopisa-dip galvanizing chirimwa, inopisa dip galvanizing line set annealing line.Rolling hard roll uremu kazhinji 6 kusvika 13.5 matani, iyo coil dhayamita ye610mm.

Iwo anowanzo kutonhora strip mill, vhoriyamu inofanirwa kuenda kuburikidza inoenderera mberi annealing (CAPL unit) kubvisa kutonhora kuomarara uye kutenderedza kushushikana, kana batch annealing inosvika kune mechaniki zvimiro zveinoenderana chiyero chinotsanangurwa.Cold yakakungurutswa simbi yepamusoro mhando, chitarisiko, dimensional kurongeka zviri nani pane inopisa-yakakungurutswa ndiro, uye kurudyi-yakakungurutswa yakatetepa chigadzirwa ukobvu ingangoita 0.18mm, saka ruzhinji rwevashandisi vanofarira.Cold yakakungurutswa simbi coil substrate zvigadzirwa zvakadzika kugadzirisa kwepamusoro kukosha-akawedzera zvigadzirwa.Senge electro-galvanized, inopisa dip galvanized, electro-galvanized fingerprint resistant, painted iron roll damping composite steel, PVC laminating steel plates, etc., kuitira kuti kunaka kwemhando yezvigadzirwa izvi kuve nekunaka, kupikisa kwepamusoro kune kuora, kwave kwave. kushandiswa zvakanyanya.Cold rolled steel coil kupera mushure mekuvhara, cheka musoro, muswe, kudimburira, kupepeta, kutsvedzerera, kurema, kana longitudinal clipboard.Zvigadzirwa zvinotonhora zvinoshandiswa zvakanyanya mukugadzira mota, midziyo yemagetsi yemumba, zviridzwa, switch, zvivakwa, fenicha yehofisi uye mamwe maindasitiri.Simbi ndiro yekusunga pasuru huremu hwematani matatu kusvika mashanu.Flat sub-vhoriyamu kazhinji 3 kusvika gumi matani / vhoriyamu.Coil dhayamita 6m.
