Seamless simbi pombi yakananga kutengesa kwezvinhu zvakasiyana-siyana
Seamless simbi pombi inoputirwa nesimbi yese yakatenderera, uye pombi yesimbi isina weld pamusoro inonzi seamless simbi pombi. Zvinoenderana nemaitiro ekugadzira, musono pombi yesimbi inogona kukamurwa kuita inopisa-yakakungurutswa seamless simbi pombi, inotonhora-yakakungurutswa seamless simbi pombi, inotonhora inodhonzwa musono pombi yesimbi, extruded seamless simbi pombi, pombi jacking, etc. Zvinoenderana nechikamu chimiro, isina musono. mapaipi esimbi akakamurwa kuita denderedzwa uye yakakosha-yakaita mapaipi. Mapaipi akasarudzika ane maumbirwo akasiyana-siyana akaomarara akadai seskweya, oval, triangular, hexagonal, mhodzi yemavise, nyeredzi uye mapaipi ane mapapiro. Iyo yakakura dhayamita i900mm uye dhayamita shoma ndeye 4mm. Zvinoenderana nemashandisirwo akasiyana, kune gobvu madziro asina musono pombi uye nhete yemadziro isina musono pombi. Seamless simbi pombi inonyanya kushandiswa se petroleum geological yekuchera pombi, inoputika pombi ye petrochemical indasitiri, boiler pombi, inotakura pombi uye yakakwirira-chaiyo chimiro chesimbi pombi yemotokari, tirakita uye nendege.
1.General chinangwa seamless simbi pombi inokungurutswa neyakajairwa kabhoni dhizaini simbi, yakaderera alloy chimiro chesimbi kana alloy chimiro chesimbi, ine yakakura kubuda. Inonyanya kushandiswa sepombi kana zvikamu zvezvimiro zvekufambisa mvura.
2. Kune marudzi matatu ekupa zvichienderana nezvinangwa zvakasiyana:
a. Ipa maererano nemakemikari ekugadzira uye mechanical properties;
b. Supply maererano ne mechanical properties;
c.Inopihwa senge hydrostatic bvunzo. Kana iyo pombi yesimbi yakapihwa zvinoenderana nekirasi A uye B yakashandiswa kutakura mvura yekumanikidza, ichave zvakare pasi pekuedzwa kwehydrostatic.
3. Mapombi asina musono ezvinangwa zvakakosha anosanganisira mapaipi asina musono emaboilers, kemikari nesimba remagetsi, mapaipi esimbi asina musono ejiology uye mapaipi asina musono epetroleum.
Seamless simbi pombi ine gomo chikamu uye inoshandiswa zvakanyanya sepombi yekufambisa mvura, senge pombi yekufambisa oiri, gasi rechisikigo, gasi, mvura uye zvimwe zvinhu zvakasimba. Kuenzaniswa nesimbi yakasimba senge simbi yakatenderedzwa, pombi yesimbi ine yakafanana flexural uye torsional simba uye kureruka uremu. Icho chikamu chehupfumi chesimbi.
Inoshandiswa zvakanyanya kugadzira zvikamu zvezvimiro uye mekiniki zvikamu, senge pombi yekuchera mafuta, mota yekufambisa shaft, bhasikoro furemu uye simbi scaffold inoshandiswa mukuvaka. Inogona kuvandudza kushandiswa kwezvinhu, kurerutsa maitiro ekugadzira, kuchengetedza zvinhu uye maawa ekugadzirisa. Yakave yakagadzirwa zvakanyanya nesimbi pombi.
① Huru yekugadzira nzira yekupisa yakakungurutswa isina musono pombi (△ huru yekuongorora maitiro):
Kugadzirira uye kuongorora pombi isina chinhu △ → kupisa kwepombi isina chinhu → kupera → pombi kutenderedzwa → kudzoreredzwa kwepombi yesimbi → saizi (kuderedza) → kurapwa kwekupisa △ → kutwasanuka kwepombi yapera → kupera → kuongorora △ (haiparadzi, muviri uye kemikari, kuongorora kwebhenji ) → kuchengetera zvinhu
② Maitiro makuru ekugadzira echando akakungurutswa (akadhonzwa) seamless simbi pombi:
Kugadzirira kusina chinhu → kunhonga uye kuzora mafuta → kukunguruka kutonhora (kudhirowa) → kurapwa kwekupisa → kutwasanudza → kupedza → kuongorora
Iyo yakajairwa kugadzirwa kweseamless simbi pombi inogona kukamurwa kuita inotonhora kudhirowa uye inopisa kukungurutswa. Iyo nzira yekugadzira inotonhora-yakakungurutswa seamless simbi pombi inowanzoomesesa pane inopisa kukungurutswa. Iyo pombi isina chinhu inofanira kutanga yave pasi pematatu roll inoenderera, uye saizi bvunzo ichaitwa mushure meextrusion. Kana pasi rikasadaira pakatsemuka, pombi yeround inofanira kutemwa nemucheki kuti icheke iyo isina chinhu nekukura ingangoita mita imwe. Zvadaro pinda annealing process. Mushonga wacho unofanira kusanganiswa nemvura ine acid. Panguva yekuchera, teerera kuti kune nhamba yakawanda yemabhuru pamusoro pepamusoro. Kana pane nhamba huru yemabhubhu, inoratidza kuti kunaka kwepombi yesimbi haigone kusangana nemitemo inoenderana. Kuonekwa kwepombi inotonhora-yakaputirwa seamless simbi ipfupi pane iyo inopisa-yakaputirwa seamless simbi pombi. Ukobvu hwemadziro epombi yesimbi isina musono inotonhora kazhinji idiki pane yepombi yesimbi isina musono inopisa, asi nzvimbo yacho inotaridzika kupenya kupfuura yepombi yakakora yesimbi isina musono. Iyo yepamusoro haina kunyanya kushata uye dhayamita haisi yakawandisa mabhura.
Mamiriro ekutumira epombi inopisa-yakanyungudutswa isina musono inowanzopisa-yakakungurutswa uye inounzwa mushure mekupisa kupisa. Mushure mekuongorora kwehutano, iyo inopisa-yakaputirwa seamless simbi pombi ichave yakanyatsosarudzwa nemaoko nevashandi. Mushure mekuongorora kwemhando, iyo nzvimbo ichazorwa mafuta, ichiteverwa neakawanda anotonhora ekudhirowa kuedza. Mushure mokupisa kunopisa, kuedza kweperforation kuchaitwa. Kana iyo perforation yekuwedzera yakakurisa, ichagadziriswa uye kururamiswa. Mushure mekutwasanuka, inopfuudzwa kune yakanganisa detector nemutakuri weyedzo yekuona kukanganisa. Pakupedzisira, inonyorwa uye inoiswa muimba yekuchengetera zvinhu mushure mekurongedzerwa kwemaitiro.
Round chubhu isina giro kana chubhu yakasimba isina chinhu kuburikidza nekuboora, uyezve inopisa yakakungurutswa, inotonhora yakakungurutswa kana kutonhora kudhonzwa. Iyo yakatarwa yesimbi isina musono pombi inoratidzwa mu mm yekunze dhayamita * madziro ukobvu.
Iyo dhayamita yekunze yekupisa-yakakungurutswa isina musono pombi kazhinji yakakura kupfuura 32mm, uye ukobvu hwemadziro ndeye 2.5-200mm. Iyo dhayamita yekunze yepombi yesimbi isina musono inotonhora inogona kusvika 6mm, ukobvu hwemadziro hunogona kusvika 0.25mm, dhayamita rekunze repombi yakatetepa-yakakomberedzwa inogona kusvika 5mm, uye ukobvu hwemadziro husingasviki 0.25mm. Cold rolling ine yakakwira dimensional accuracy pane inopisa kukunguruka.
Kazhinji, pombi dzesimbi dzisina musono dzakagadzirwa nemhando yepamusoro kabhoni dzakasungwa simbi dzakadai se10, 20, 30, 35 uye 45, yakaderera-alloy zvimiro zvesimbi zvakaita se16Mn uye 5mnv, kana simbi dzakasungwa se40Cr, 30CrMnSi, 40MnB uye 40MnB. 10. Mapombi asina musono akagadzirwa nesimbi yakaderera kabhoni akaita se20 anonyanya kushandiswa pakufambisa mapaipi. Mapombi asina musono akagadzirwa nepakati kabhoni simbi senge 45 uye 40Cr anoshandiswa kugadzira mekiniki zvikamu, senge zvakatsikirirwa zvikamu zvemotokari nematirakita. Kazhinji, iyo simba uye kudzika bvunzo yesimbi isina musono pombi ichave yakavimbiswa. Mapaipi esimbi anopisa anokungurutswa achaunzwa munzvimbo inopisa yekukungurutsira kana kupisa kupisa; Cold rolling inounzwa mumamiriro ekupisa.
Kupisa kutenderedza, sezvinoreva zita, tembiricha yechidimbu chakapetwa yakakwira, saka iyo deformation kuramba idiki uye yakakura deformation inogona kuitika. Tichitora kukungurutswa kwendiro yesimbi semuenzaniso, ukobvu hwekuramba uchikanda slab kazhinji hunosvika 230mm, nepo mushure mekukunguruka nekupedza kukunguruka, ukobvu hwekupedzisira i1 ~ 20mm. Panguva imwe chete, nokuti hupamhi ukobvu reshiyo yesimbi ndiro idiki uye zvinodiwa kuti dimensional kunyatsoita yakaderera, dambudziko chimiro hakusi nyore kuitika, uye convexity rinonyanya kudzorwa. Kune avo vane zvinodiwa nesangano, zvinowanzoitika kuburikidza nekudzora kutenderedzwa uye kudzorwa kutonhora, ndiko kuti, kudzora tembiricha yekutenderera uye tembiricha yekupedzisira yekukunguruka. chubhu yakatenderedzwa isina chinhu → kudziyisa → perforation → heading → annealing → pickling → kuzora (copper plating) → multi pass inotonhora kudhirowa (inotonhora kukungurutswa) → blank chubhu → kupisa kupisa → kutwasanura → hydrostatic test (kuona kukanganisa) → kumaka → kuchengetera zvinhu.
