1. Lub hauv paus tau faib: Erw vs. Seamless (sms) yeeb nkab
Qhov kev sib txawv tshaj plaws hauv cov yeeb nkab steel hlau tsim cov lus dag ntawm welded kav, zoo liHlob, thiab cov kav dej seamless.Dab tsi yog erw yeeb nkabntawm nws cov tub ntxhais? Nws muaj qhov sib txawv ntev ntev weld seam tsim los ntawmhluav taws xob tiv thaiv vuamtxheej txheem. Nyob rau hauv stark sib piv, seamless yeeb (sms) yog tsim yam uas tsis muaj kev xav weld ntev. Nws qhov kev tsim pib nrog cov khoom cylindrical cov hlau billet, uas yog rhuab thiab chob los ntawm nws lub chaw siv lub tsev. Cov kab mob no yog lub ntsej muag zoo nkauj thiab zoo li cov yeeb nkab los ntawm cov txheej txheem rollcing, zoo li cov txheej txheem teb (ncab) uas txo cov phab ntsa tuab thiab ua kom lub cheeb. Qhov tsis muaj ntawm Weld Seam yog ib qho kev txhais tau ntau tshaj plaws ntawm cov yeeb nkab uas tsis yog leej twg thiab underpins nws thawj qhov zoo. Tus qauv seamless muaj cov kev sib txuam zoo hauv cov tshuab tshuab thiab microstructure nyob ib ncig ntawm cov yeeb nkab. Nws tshem tawm cov seamtudinal ntev, uas tau pom tias yog qhov xwm txheej tsis muaj zog lossis kev pib ua kom nkees, txawm hais tias niaj hnub noERW STEEL YEEBUa rau cov tswj hwm nruj heev cov khoom ua pov thawj zoo heev Weld kev ncaj ncees. Qhov no tau txais homogeneity ua seamless yeeb nkab cov kev xaiv uas nyiam tshaj plaws uas muaj tshuaj lom neeg, lossis cov kev pabcuam kub heev}. Txawm li cas los xij, qhov no los ntawm tus nqi tseem ceeb. Seamless manufacturing yog inherently qeeb qeeb, ntau zog - heev thiab siv ntau dua cov machinery tshaj li siab {9} ceev erw ntau lawm. Tsis tas li ntawd, seamless yeeb nkab faces tswv yim hauv kev ua kom tiav cov txheej txheem loj loj piv rau txoj kev welded zoo li pom.Dab tsi erw txhais tau tiasHauv qhov kev sib piv no yog tus nqi siab heev - Cov kev siv diamity thiab kev ntseeg tau rau qhov kev sib tw nruab nrab ntawm kev sib tw ntawm seamless tsis yog nruj me ntsis. TusLub ntsiab lus ntawm ERW YEEBYog li suav nws lub luag haujlwm raws li kev ua tau zoo, kev lag luam xaiv rau seamless rau tsis yog} {{{1} qhov siab {1} qhov siab {1} qhov siab {1} kev pabcuam siab.
2. Kev sib tw vuam technologies: erw vs longitudinal submerged arc vuam vuam vuam (lsaw)
Tsis pub dhau lub realm ntawm welded yeeb nkab,HlobNtsej muag nws txoj kev sib tw tseem ceeb tshaj plaws los ntawm submerged arc vuam (pom), tshwj xeeb yog qhov ntev pom (lsaw) variant. Thaum ob qho tib si tsim cov kav dej nrog cov txheej txheem ntev, cov txheej txheem vuam yog txawv, ua rau muaj cov khoom ntiag tug thiab cov khoom siv sib txawv thiab cov ntawv thov niches.Dab tsi yog erw yeeb nkabHais txog nws weld? Cov txheej txheem ERW tsim cov weld los ntawm cov hluav taws xob tsis kam siv hluav taws xob hauv zos thiab tshuab kev lom zemtsis muajntxiv cov tub rog cov hlau. Cov cua sov yog tsim tawm sab hauv hauv cov hlau los rau sab. LSAW, hloov, yog ib txoj kev sib tw arc vuam. Nws pib nrog ib phaj steel (kos duab phaj) uas tau nias lossis dov mus rau hauv ib tug u}}}}} Cov txheej txheem) ua ntej kawg {5 5} Sib ua ke Lub sijhawm ntev seam yog tom qab ntawd welded siv ib lossis ntau dua cov hlau txuas ntxiv hluav taws xob. Cov txiaj ntsig tseem ceeb nyob hauv ARC: tus arc hluav taws xob raug tsoo ntawm cov (cov) thiab cov haujlwm ua haujlwm. Qhov tseem ceeb, qhov no arc thiab pas dej weld yog tso rau hauv qab ntawm daim pam ntawm granular flux. Qhov no flux melts, sib sau lub tiv thaiv cov txheej tiv thaiv uas thaiv cov hlau los ntawm cov hlau los ntawm cov pa hluav taws xob (oxygen), thiab ntxiv cov ntsiab lus siv hlau. Nws tseem ua raws li cov tshuaj kho mob thermal, cia kom tob nkag thiab ua kom txias qeeb qeeb. Cov txheej txheem no muaj feem cuam tshuam txog kev muab tub lim hlau, tsim kom muaj weld hlaws uas tuab thiab pom kev yooj yim los yog me ntsis erw seam tom qab flash tshem tawm. Qhov kev tso nyiaj tshuav no ua rau LSAW excomeally zoo-}}}}}}}}) thiab lub taub hau ntau dua li 16 "thiab txuas ntxiv rau ntawm 16" thiab txuas ntxiv dhau 80 "). Lub qeeb txuas vuam ceev piv rau cov ERW yog offset los ntawm lub peev xwm los lis cov loj dua, hnyav tshaj ntu kev lag luam. Thiaj li, LSAWAS yog tus txheej txheem tseem ceeb rau loj- Cov khoom siv dej loj, thiab cov tshuab hluav taws xob siab yog qhov tseem ceeb.Dab tsi erw txhais tau tiasNyob rau hauv kev sib piv yog tus txheej txheem optimized rau kev nrawm nrawm thiab ua haujlwm hauv lub qhov nruab nrab nrog nyias {} - nruab nrab phab ntsa. Tushluav taws xob tiv thaiv welded steel yeeb nkabExcels qhov chaw ntau lawm, cov khoom siv sab hauv thiab sab nraud ua kom zoo, thiab cov khoom siv sab nraud, thiab cov txheej txheem sib txawv, thiab cov ntawv thov neeg kho txhua yam. TusERW cov yeeb nkab ntsiab lusYog li hais txog kev ua tau zoo thiab precision rau nws lub hom phiaj loj, thaum LSAWW RIGHT WELD Depositioning hnyav {- Txoj kab ke ntawm txoj kab uas hla ntawm txoj kab uas hla.
3. Tus KAUV: ERW piv thiab Kauv Submerged Arc Vuam Vuam (SSAW)
Lwm qhov tseem ceeb welded yeeb cov txheej txheem yog kauv submerged arc vuam vuam (ssaw). Zoo li LSAW, nws siv cov submerged arc vuam txheej txheem nrog cov xaim xaim thiab granular flux. Txawm li cas los xij, nws txoj kev tsim thiab vuam ze sib txawv sib txawv los ntawm ob lsaw thiabHlobCov. SSAW tus yeeb nkab yog tsim los ntawm kev tsim cov kev sib txuas lus ntawm txoj kev kauv (kauv) sib. Kub {- rolled steel sawb (kauj) tau pub ntawm lub kaum sab xis rau kev tsim manrel. Qhov kev pub mis ib yam kev txiav txim siab cov yeeb nkab lub taub. Raws li cov kab txaij yog qhov txhab ua rau lub siab tawv, cov npoo sib tshooj ntawm cov tog sab nraud ua ke ntawm kev siv tog arc Qhov no ua rau muaj cov kab ke ntawm cov kab ntawm Weld Seam uas sau tag nrho ntev ntawm cov yeeb nkab. Cov ntsiab lus tseem ceeb ntawm swsaw yog qhov yooj yim zoo nyob rau hauv kev ua diameters (li ntawm 20 "thiab dhau mus txog 100" thiab dhau mus li ntawm 20 "thiab dhau ntawm 20" thiab dhau ntawm cov khoom siv nqaim Cov txheej txheem tuaj yeem ua rau muaj ntau yam diameters yam tsis hloov pauv cov ntawv mandrel, tsuas yog kho cov sawb pub lub kaum sab xis. Qhov no ua rau nws haum rau cov kev xav tau cov diameters loj tab sis weld zoo heev xav tau kev thev naus laus zis tej zaum yuav tsis tshua tseem ceeb tshaj rau lsaw. Cov kev siv cov kev siv suav nrog qis dua {13} cov roj siab thiab roj kev thauj khoom, cov khoom siv roj tsheb loj, piling, thiab qee cov qauv kev siv.Dab tsi yog erw yeeb nkabpiv rau ssaw? ERW yog nyob rau ibntev heevvuam txheej txheem vuam. Nws txoj hlua khi ncaj nraim raws cov yeeb nkab ntev, tsis yog kauv. Tushluav taws xob tiv thaiv vuamTxheej txheem ua rau cov weld tsis muaj tais diav los ntawm kev ua cua sov nrog SSAW cov tub lim hlau depigition ntawm submerged arc. ERW feem ntau ua tiav qhov tseeb ntawm cov neeg siab dua (ncaj, ncaj qha, uas tuaj yeem tshwm sim me ntsis tsis muaj sijhawm vim yog kauv. Cov Kauv Weld geometry ntawm SSAW tawm ntawm Weld Seam uas ntev dua li cov yeeb nkab nws tus kheej, muaj peev xwm nce ntxiv qhov ntev kawg ntawm Weld xav tshuaj xyuas. Erw lub siab - ceev ntau heev yog feem ntau cov phiaj xwm ntawm cov diameters me dua li ssaw. Yog li ntawd, tusERW cov yeeb nkab ntsiab lusTxoj haujlwm nws yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov kom muaj txiaj ntsig zoo, thiab cov kab ke du thiab muaj txiaj ntsig zoo ntawm cov khoom lag luam ntev lossis lsaw tsis tas yuav.
4. Cov ntsiab lus keeb kwm: ERW vs. rauv taws rauv vuam (FBW)
Kom zoo siab rau kev nce qib sawv cev los ntawm niaj hnubHlob, Nws yog qhia los piv nws rau tus laus dua, lom zem ntau welded yeeb kev siv hom: rauv taws hauv qab vuam (FBW). FBW yog keeb kwm tseem ceeb, tshwj xeeb tshaj yog rau kev tsim cov kav dej me me. Tus txheej txheem koom nrog thawj cov cua sov xaus ntawm kev txiav- ntev hlau sawb (skelp) nyob rau hauv lub cub tawg kom txog thaum lawv tau mus txog lub xeev yas. Lub rhuab sawb yog ces rub los ntawm lub tswb nrov {{}} zoo li tus yob los yog cov ntaub qhwv uas tau ua rau nws mus rau hauv cov duab cylindrical. Raws li cov cua sov, cov npoo yas ntawm cov kab txaij raug coj ua ke thaum tawm ntawm kev tawm ntawm kev tsim tuag lossis yob, lawv tau raug tso rau hauv Weld. Qhov no yog qhov tseem ceeb ib qho kev ruaj khov - lub xeev txuas rau cov txheej txheem kev txhawb nqa ntawm cov cub hluav taws xob. Thaum yooj yim hauv lub tswvyim, FBW muaj cov kev txwv tseem ceeb. Kev tswj hwm kev tswj hwm ntau dua qhov kev sib tw cua kub thiab kev zam txim tau nyuaj, feem ntau ua rau tsis sib xws weld zoo. Lub weld cheeb tsam feem ntau muaj cov oxides thiab suav nrog rau thaum lub sijhawm forging. Qhov tseeb ntawm qhov tseeb (lub taub, roundness, ncaj) yog feem ntau tsis zoo piv rau niaj hnub txias {12} muaj cov yeeb nkab niaj hnub.
