Kubudirira nhoroondo ye seamless simbi pombi
Seamless simbi pombi kugadzirwa ane nhoroondo yeanoda kusvika 100 makore.Hama dzeGermany Mannesmann dzakatanga kugadzira two roll cross rolling piercer muna 1885, uye periodic pipe mill muna 1891. Muna 1903, Swiss RC stiefel yakagadzira chigayo chepombi chigayo (chinozivikanwawo sechigayo chepombi yepamusoro).Mushure meizvozvo, michina yekuwedzera yakasiyana-siyana senge inoenderera mberi pombi mill uye pombi jacking muchina yakaonekwa, iyo yakatanga kuumba yemazuva ano seamless simbi pombi indasitiri.Muma1930, nekuda kwekushandiswa kwetatu roll pombi rolling mill, extruder uye periodic inotonhora inotenderedza chigayo, akasiyana uye kunaka kwepombi dzesimbi zvakavandudzwa.Mumakore ekuma1960, nekuda kwekuvandudzwa kwepombi chigayo chinoramba chiripo uye kubuda kwevatatu vanoboora, kunyanya kubudirira kwemakakatanwa ekudzikisa chigayo uye kuenderera mberi kukanda billet, kushanda zvakanaka kwekugadzira kwakavandudzwa uye kukwikwidzana pakati pepombi isina musono uye pombi yakakandwa yakawedzerwa.Mumakore ekuma1970, pombi isina musono uye pombi yakakandwa zvairamba zvichimhanya, uye kubuda kwepombi yesimbi pasi rose kwakawedzera pamwero unodarika 5% pagore.Kubva 1953, China yakawedzera kukosha pakusimudzira indasitiri yesimbi isina musono pombi, uye yakatanga kugadzira nzira yekugadzira yekukungurutsa marudzi ese makuru, epakati uye madiki pombi.Kazhinji, pombi yemhangura inotorawo maitiro e billet cross rolling uye kuboora.
Kushandiswa uye kupatsanurwa kweseamless simbi pombi
Application:
Seamless simbi pombi imhando yehupfumi chikamu simbi, iyo inoita basa rakakosha muhupfumi hwenyika.Inoshandiswa zvakanyanya mupetroleum, indasitiri yemakemikari, bhaira, chiteshi chemagetsi, ngarava, kugadzira michina, mota, ndege, ndege, aerospace, simba, geology, kuvaka, indasitiri yemauto nemamwe madhipatimendi.
Classification:
① Zvinoenderana nechikamu chechimiro: denderedzwa chikamu pombi uye yakakosha chikamu pombi.
② zvinoenderana nezvinhu: kabhoni simbi pombi, alloy simbi pombi, Stainless simbi pombi uye composite pombi.
③ zvinoenderana neiyo nzira yekubatanidza: tambo yekubatanidza pombi uye welded pombi.
④ zvinoenderana nemaitiro ekugadzira: kupisa kutenderedza (extrusion, jacking uye kuwedzera) pombi uye kutonhora kutenderedza (kudhirowa) pombi.
⑤ zvinoenderana nechinangwa: boiler pombi, pombi yemafuta pombi, pombi pombi, pombi yekugadzira uye kemikari fetiraiza pombi.
Kugadzira tekinoroji yesimbi isina musono pombi
① Huru yekugadzira maitiro (main yekuongorora maitiro) yekupisa yakakungurutswa isina musono pombi yesimbi:
Tube kugadzirira uye kuongorora → chubhu isina kupisa kupisa → perforation → kutenderedza chubhu → kudziyisazve yechubhu mbishi → saizi (kuderedza) → kurapwa kwekupisa → kutwasanuka kwechubhu yapera → kupedza → kuongorora (kusingaparadzi, muviri uye kemikari, bhenji bvunzo) → kuchengetera zvinhu.
② Maitiro makuru ekugadzira echando akakungurutswa (akadhonzwa) isina musono simbi pombi
Kugadzirira kusina chinhu → kunhonga nekuzora → kukunguruka kutonhora (kudhirowa) → kurapwa kwekupisa → kutwasanudza → kupedza → kuongorora.
Iyo yekugadzira inoyerera chati yekupisa yakakungurutswa seamless simbi pombi yakaita seinotevera:
