Musiyano uripo pakati pekutonhora-yakakungurutswa seamless simbi pombi uye inopisa-yakakungurutswa seamless simbi simbi Kupisa-yakakungurutswa uye inotonhora-yakakungurutswa simbi ese ari simbi kana simbi kuumba maitiro, ane simba guru pasangano uye kushanda kwesimbi, simbi inokungururuka inonyanya Kupisa ndiyo nzira huru, uye kutonhora kunotonhora kunoshandiswa chete pakugadzirwa kwesimbi duku uye mapepa.
1. Hot rolling Advantages: Inogona kuparadza ingot casting structure, kunatsa zviyo zvesimbi, uye kubvisa zvikanganiso zve microstructure, kuitira kuti chimiro chesimbi chive chakaoma uye michina yemagetsi inovandudzwa.Kuvandudzwa uku kunonyanya kuratidzwa mugwara rekukunguruka, kuitira kuti simbi isisiri isotropic;kune imwe nhanho, mabhubhu, kuputika uye kusununguka kwakaumbwa panguva yekudururwa kunogonawo kusungirirwa pasi pekushisa kwakanyanya uye kumanikidzwa.
Kukanganisa: 1. Mushure mokupisa kunopisa, iyo isiri-metallic inclusions (kunyanya sulfides uye oxides, uye silicates) mukati mesimbi inomanikidzwa kuva mashizha matete uye kuputika (sandwich) chiitiko chinoitika.Stratification inoshatisa zvakanyanya zvimiro zvesimbi muhukobvu gwara, uye zvinogoneka kuti kubvaruka kwepakati kunoitika kana weld seam yadzikira.Nharaunda yemunharaunda inokonzerwa ne weld shrinkage inowanzosvika kakawanda kushungurudza panguva yegoho, iyo yakakura zvikuru kupfuura iyo inokonzerwa nemutoro;2. Kushungurudzika kwakasara kunokonzerwa nekutonhora kusina kuenzana.Residual stress is stress of the internal self-phase equilibrium pasi pekuita pasina simba rekunze.Kupisa kwakaputirwa simbi yezvikamu zvakasiyana-siyana ine kusara kwakadaro kunetseka.Iyo yakakura saizi yechikamu chesimbi yakawanda, iyo yakakura yekusarira kunetseka.Kunyange zvazvo kushushikana kwakasara kuri kuzvidzora, kunoramba kune imwe simba pakushanda kwezvikamu zvesimbi pasi pemasimba ekunze.Zvakadai sedeformation, kugadzikana, anti-kuneta uye zvimwe zvinhu zvinogona kuve nemhedzisiro yakaipa.
Kutengeswa kwepombi hobvu-yakakomberedzwa nesimbi isina musono pombi, hombe-dhayamita isina musono pombi yesimbi, inopisa-inoparadzira musono vanogadzira pombi dzesimbi - Shandong Liaogang Metal.
Cold Rolling (Cold Rolling) zvinoreva kugadzikiswa kwesimbi ndiro kana tambo kuita marudzi akasiyana-siyana esimbi panotonhora nekudhirowa kunotonhora, kukotama kunotonhora, kudhirowa kunotonhora, nezvimwewo pachitonhora.
Zvakanakira: kukurumidza kuumba kukurumidza, chibereko chakakwirira, uye hapana kukuvadzwa kwekuputira, kunogona kuitwa mumhando dzakasiyana-siyana dzepamuchinjikwa kuti dziite zvinodiwa zvekushandiswa kwemamiriro ezvinhu;kutonhora kunotonhora kunogona kuita kuti simbi ibudise hombe yepurasitiki deformation, nokudaro ichiwedzera goho resimbi.
Zvakaipa:1.Kunyange zvazvo pasina kupisa kwepurasitiki kumanikidzika mukugadzirisa kwekugadzira, kuchine zvakasara zvinonetsa muchikamu, izvo zvichange zvisingadzivisiki zvinokanganisa zvinhu zvesimbi sese uye kuputika kwenzvimbo;2. Cold rolled chikamu simbi style inowanzozaruka chikamu, zvichiita kuti chikamu chisunungurwe Kuoma kwepasi torsional.Inoita kumonyoroka panguva yekukotama, kukotama uye torsion buckling inowanzoitika panguva yekumanikidzana, uye kuramba kwetorsion kwakashata.3. Ukobvu hwemadziro esimbi inotonhora-yakakungurutswa yakaumbwa idiki, uye haina kuomeswa pamakona apo mahwendefa anobatana, uye inogona kumira munzvimbo.Kugona kuisa pfungwa pamitoro hakuna simba.
Kutengeswa kwepombi hobvu-yakakomberedzwa nesimbi isina musono pombi, hombe-dhayamita isina musono pombi yesimbi, inopisa-inoparadzira musono vanogadzira pombi dzesimbi - Shandong Liaogang Metal.
Misiyano mikuru pakati pekupisa nekutonhora kukunguruka ndeiyi:
1. Masimbi anotonhora akaumbwa anobvumira buckling yemunharaunda ye-cross-section kuitira kuti post-buckling inotakura simba inogona kushandiswa zvizere;simbi inopisa-yakaputirwa haibvumiri buckling yemunharaunda ye-cross-section.
2. Zvinokonzera kusara kwekunetseka musimbi inopisa-yakaputirwa uye simbi inotonhora yakasiyana, saka kugoverwa pamuchinjikwa kwakasiyanawo.Iyo yakasara yekushushikana kugovera pane inotonhora-yakaumbwa yakaonda-madziro chikamu simbi yakakomberedzwa, nepo yasara yekushushikana kugovera pane inopisa-chikamu kana welded chikamu itete-firimu mhando.
3. Kuoma kwehutu hwesimbi inopisa-yakaputirwa yakakwirira kudarika yesimbi inotonhora, saka kushanda kwehutu hwesimbi inopisa-inopisa iri nani kupfuura yesimbi inotonhora.
