Cold yakakungurutswa isina musono pombi (GB3639-2000) inotonhora inodhonzwa kana kutonhora yakatenderedzwa chaiyo isina musono pombi yesimbi ine yakakwirira dimensional kurongeka uye yakanaka kupedzwa kwepamusoro kwemakanika chimiro uye hydraulic michina. Pamusoro pepombi yesimbi yakajairika, yakaderera uye yepakati kumanikidza boiler simbi pombi, yakakwira boiler simbi pombi, alloy simbi pombi, pombi yesimbi isina tsvina, peturu inopwanya pombi uye mamwe mapombi esimbi, inotonhora yakakungurutswa (yakadhonzwa) isina musono pombi inosanganisirawo kabhoni nhete-yakavharidzirwa. pombi yesimbi, alloy yakatetepa-yakakomberedzwa simbi pombi, simbi isina tsvina-yakatetepa pombi uye yakakosha-yakaita sesimbi pombi. Iyo dhayamita yekunze yekupisa-yakakungurutswa isina musono pombi kazhinji yakakura kupfuura 32mm uye ukobvu hwemadziro ndeye 2.5-75mm. Iyo dhayamita yepombi yesimbi isina musono inotonhora inogona kusvika 6mm uye ukobvu hwemadziro hunogona kusvika 0.25mm. Iyo dhayamita yekunze yepombi yakatetepa-yakakomberedzwa inogona kusvika 5mm uye ukobvu hwemadziro husingasviki 0.25mm. Cold rolling ine yakakwira dimensional accuracy pane inopisa kukunguruka.
1.Cold rolled steel inobvumira buckling yemunharaunda yechikamu, iyo inogona kushandisa zvizere simba rekutakura renhengo mushure mekuputika; Iyo inopisa-yakaputirwa chikamu simbi haibvumire buckling yemunharaunda.
2.Zvikonzero zvekusarira kushushikana mune inopisa yakakungurutswa chikamu simbi uye inotonhora yakakungurutswa chikamu simbi zvakasiyana, saka kugovera pane chikamu zvakare kwakasiyana kwazvo. Iyo yakasara yekushungurudzika kugovera pachikamu chesimbi inotonhora-yakaumbwa yakaonda-yakakomberedzwa chikamu chesimbi inokotama mhando, nepo yakasara yekushushikana kugovera pachikamu chechikamu chinopisa-chakakungurutswa simbi kana welded chikamu simbi itete-firimu mhando.
3. Iyo yemahara torsion kuomarara kweanopisa-akakungurutswa chikamu simbi yakakwirira kupfuura inotonhora-yakakungurutswa chikamu simbi, saka torsion resistance ye inopisa-yakakungurutswa chikamu simbi iri nani pane inotonhora-yakakungurutswa chikamu simbi.
Cold rolling inoreva kugadzirwa kwesimbi ndiro kana tambo kuita mhando dzakasiyana dzesimbi patembiricha yepakamuri kuburikidza nekudhirowa kunotonhora, kukotama kutonhora, kudhirowa kunotonhora uye kumwe kutonhora.
Zvakanakira:kukurumidza kuumba kukurumidza, kuburitsa kwakakwira, hapana kukuvadzwa kwejasi, uye inogona kuitwa mumhando dzakasiyana-siyana dzepamuchinjikwa mafomu kusangana nezvinodiwa zvemamiriro ebasa; Cold rolling inogona kuburitsa hombe yepurasitiki deformation yesimbi, kuitira kuvandudza goho poindi yesimbi.
Zvakaipa:1. Kunyange zvazvo pasina kupisa kwepurasitiki kumanikidzika mukugadzirwa kwekugadzira, kuchine kusara kunetseka muchikamu, izvo zvichange zvichikanganisa maitiro ose uye emunharaunda buckling yesimbi; 2. Chimiro chechando chakaputirwa chikamu chesimbi chinowanzovhurika chikamu, kuitira kuti kusununguka kwekuoma kwechikamu kwechikamu kwakaderera. Torsion iri nyore kuitika mukukotama, kukotama uye torsional buckling iri nyore kuitika mukumanikidzana, uye kuita kwe torsional kwakashata; 3. Ukobvu hwemadziro esimbi inotonhora-yakakungurutswa yakaumbwa idiki, uye hapana kukora pakona yekubatanidza kweplate, saka kugona kutakura mutoro wakanyanya wemunharaunda hauna simba.
Kuenzaniswa neinotonhora-yakakungurutswa isina musono pombi, inopisa-yakakungurutswa isina musono pombi inokungurutswa pazasi recrystallization tembiricha, uye inopisa-yakakungurutswa seamless pombi inokungurutswa pamusoro peiyo tembiricha recrystallization.
Zvakanakira:inogona kuparadza chimiro chekukanda che ingot, kunatsa zviyo zvesimbi uye kubvisa kukanganisa kwe microstructure, kuitira kuti simbi igadzikane uye ivandudze michina yemagetsi. Kuvandudzwa uku kunonyanya kuratidzwa mugwara rekukunguruka, kuitira kuti simbi haisisiri isotropic kune imwe nhanho; Mabhubhu, kutsemuka uye kusununguka kwakaumbwa panguva yekudururwa kunogona zvakare kusungirirwa pasi pechiito chekushisa kwakanyanya uye kudzvanywa.
Zvakaipa:1. Mushure mokupisa kunopisa, iyo isiri-metallic inclusions (kunyanya sulfide, oxide uye silicate) musimbi inomanikidzwa kuva mashizha matete, zvichiita kuti delamination (interlayer) chiitiko. 2. Delamination inokanganisa zvakanyanya kusimba kwesimbi pamwe chete negwara reukobvu, uye kubvaruka kwepakati kunogona kuitika kana weld yadzikira. Nharaunda yemunharaunda inokonzerwa ne weld shrinkage inowanzosvika kakawanda yegoho rekutsvaga, iyo yakakura kudarika iyo inokonzerwa nemutoro; 2. Kushungurudzika kwakasara kunokonzerwa nekutonhora kusina kuenzana. Residual stress ndiyo yemukati self-equilibrium stress pasina simba rekunze. Zvikamu zvinopisa zvakatenderedzwa zvezvikamu zvakasiyana zvine rudzi urwu rwekushushikana kwakasara. Kazhinji, iyo yakakura chikamu chechikamu chesimbi yechikamu, iyo yakanyanya kusara kunetseka. Kunyangwe kushushikana kwasara kuri kuzvienzanisa, kuchiri kune imwe mhedzisiro pakuita kwenhengo dzesimbi pasi pesimba rekunze. Semuenzaniso, inogona kuva nemigumisiro yakaipa pa deformation, kugadzikana uye kuneta kuramba. 3. Ukobvu uye rutivi rwakafara rwezvigadzirwa zvesimbi zvinopisa hazvisi nyore kudzora. Isu tinoziva nekuwedzera kwekushisa uye kutonhora kwechando. Kunyange kana kureba uye ukobvu zvichisangana nechiyero pakutanga kwekukunguruka kunopisa, pachava nemusiyano wakashata mushure mekutonhora. Iyo yakafara kumucheto kwehupamhi yemusiyano uyu wakashata ndeyekuti, iyo yakawedzera ukobvu, ndiyo inonyanya kuoneka. Nokudaro, nokuda kwesimbi huru, rutivi rwakafara, ukobvu, kureba, kona uye mutsara wepamucheto wesimbi haigoni kudiwa kuti ive yakarurama.
