Pfupiso ye coil inotonhora yakakungurutswa

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.

Maitiro Ekugadzira Coil Yakaputirwa neCold

Coil inotonhorera inogadzirwa necoil inotonhorera inodziya, uye maitiro ekugadzira kwayo anowanzo pfuura nepakati pemaitiro makuru akadai sekugadzirira zvinhu zvisina kugadzirwa, kutenderedza kunotonhora, kurapwa nekupisa, kuenzana uye kupedzisa.

Kushanda kwechigadzirwa cheCold Rolled Coil

Roro nepiritsi zvinenge zvakachekwa. Roro rinotonhorera rinowanikwa nekukanda uye kukanda roro rinopisa rinotonhorera. Zvinogona kunzi imhando yeroro rinotonhorera rinotonhora. Roro rinotonhorera rinotonhora (mamiriro akabatanidzwa): Roro rinotonhorera rinopisa rinowanikwa nekukanda, kukanda rororera kunotonhora, kukanda hood, kuenzana, (kupedzisa).

Pane misiyano mikuru mitatu pakati pavo:

Pachitarisiko, jira rinotonhorera harina kunyatsojeka.

Mapepa akamonerwa anotonhora akadai semhando yepamusoro, chimiro uye kurongeka kwehukuru hwechinhu chiri pamusoro zviri nani pane macoil anotonhorera.

Panyaya yekushanda, coil inotonhorera inowanikwa zvakananga mushure mekutonhora kwekumonera kwecoil inotonhorera inooma panguva yekumonera inotonhora, zvichiita kuti simba rekugadzira riwedzere uye chikamu chekushushikana kwemukati chisarambe chiripo, uye chitarisiko chekunze "chakaoma". Inonzi coil inotonhorera.

Saka, simba remubereko: coil inotonhorera yakakura kupfuura coil inotonhorera (annealed state), saka coil inotonhorera (annealed state) inonyanya kunaka pakuisa stamping. Kazhinji, mamiriro ekutumira anowanzoitwa cold rolled coils anonamirwa.

Kushandiswa kwepepa resimbi rinotonhora rakamonerwa

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.

Mhando dzekushandisa:
(1) Kugadzira jira rinoita serinotenderera rinotonhora mushure mekunamirwa; kuputira;
(2) Chigadziko chekugadzira magasi chine mudziyo wekugadzirisa magasi chinogadziriswa kuti chigadzirwe magasi;
(3) Mapaneru asingade kugadziriswa zvachose.
