Musiyano pakati peHot Rolled Steel uye Cold Rolled Steel

Vatengi vanowanzotibvunza nezve mutsauko pakati pesimbi inopisa yakakungurutswa nesimbi inotonhora.Pane misiyano yakakosha pakati pemhando mbiri idzi dzesimbi.Misiyano pakati pesimbi inopisa yakakungurutswa nesimbi inotonhora inotenderedzwa ine chekuita nemagadzirirwo anoita simbi idzi paguyo, uye kwete kutsanangurwa kwechigadzirwa kana giredhi.Simbi inopisa yakakungurutswa inosanganisira kukungurutsa simbi patembiricha yakakwira, uko simbi inotonhora inokungurutswa inogadziridzwazve mumagiyo ekuderedza kutonhora uko zvinhu zvinotonhodzwa zvichiteverwa nekunyungudika uye/kana hasha.

Kupisa Yakakungurutswa Simbi
Kupisa kukungurutsira chigayo kunosanganisira kukungurutsa simbi patembiricha yepamusoro (kazhinji patembiricha inopfuura 1700° F), iri pamusoro petembiricha yesimbi.Kana simbi iri pamusoro pe tembiricha recrystallization, inogona kuumbwa uye kuumbwa nyore, uye simbi inogona kugadzirwa muhukuru hwakakura.Simbi inopisa yakatenderedzwa kazhinji yakachipa kupfuura inotonhora yakakungurutswa simbi nekuda kwekuti inowanzo gadzirwa pasina kunonoka mukuita, uye saka kudzoreredzwa kwesimbi hakudiwi (sezvazviri nechando chakakungurutswa).Kana simbi yatonhora inodzikira zvishoma nokudaro ichipa kudzora kushoma pahukuru uye chimiro chechigadzirwa chakapedzwa kana ichienzaniswa nechando chakakungurutswa.

Zvishandiso: Zvigadzirwa zvinopisa zvakakungurutswa semasimbi anopisa anokungurutswa anoshandiswa mukutengesa nekuvaka kugadzira njanji uye I-matanda, semuenzaniso.Kupisa kwakaputirwa simbi inoshandiswa mumamiriro ezvinhu apo maumbirwo chaiwo uye kushivirira hazvidiwi.

Cold Rolled Steel
Cold rolled steel isimbi inopisa yakakungurutswa yave nekumwe kugadzirisa.Simbi inogadziridzwa zvakare mumagiyo ekuderedza kutonhora, uko zvinhu zvinotonhodzwa (pakamuri tembiricha) zvichiteverwa neannealing uye/kana hasha dzichikunguruka.Iyi nzira ichagadzira simbi ine padhuze dimensional tolerances uye yakakura siyana yekupedzisa kwepamusoro.Izwi rekuti Cold Rolled rinoshandiswa zvisirizvo pazvigadzirwa zvese, kana zita rechigadzirwa richireva kukungurutswa kwepepa rakapetwa uye zvigadzirwa zvecoil.

Kana tichitaura nezvezvigadzirwa zvemabhawa, izwi rinoshandiswa nderekuti "kupedza kutonhora", iyo inowanzo sanganisira kutonhora kudhirowa uye / kana kutendeuka, kukuya nekupukuta.Iyi nzira inoguma negoho repamusoro uye ine mabhenefiti mana makuru:

Kudhirowa kutonhora kunowedzera goho uye kusimba kwesimba, kazhinji kubvisa kumwe kudhura kwekurapa kwekupisa.
Kutendeuka kunobvisa kusakwana kwepamusoro.
Kukuya kunotatamura saizi yepakutanga yekushivirira.
Kupukuta kunonatsiridza kupera kwepamusoro.
Zvese zvigadzirwa zvinotonhora zvinopa yepamusoro yepamusoro kupedzisa, uye yakakwirira mukushivirira, concentricity, uye kutwasanuka kana ichienzaniswa nekupisa kwakatenderedzwa.

Mabhawa anotonhora akapera anowanzo kuoma kushanda nawo pane kupisa akakungurutswa nekuda kwekuwedzera kabhoni yemukati.Nekudaro, izvi hazvigone kutaurwa nezve inotonhora yakakungurutswa pepa uye inopisa yakakungurutswa pepa.Nezvigadzirwa zviviri izvi, iyo inotonhora yakakungurutswa chigadzirwa ine yakaderera kabhoni yemukati uye inowanzo nyuchirwa, ichiita kuti ive yakapfava kupfuura inopisa yakakungurutswa pepa.

Zvishandiso: Chero chirongwa uko kushivirira, mamiriro epamusoro, kutarisisa, uye kutwasuka ndizvo zvinhu zvikuru.
