Submerged arc steel yeeb nkab txoj kev tsim muaj xws li nruam twist txoj kev (HME), yob txoj kev (CFE), Uing Oing Expanding forming method (UOE), yob dabtsi yog khoov txoj kev (RBE), Jing Cing Oing nthuav txoj kev (JCOE), thiab lwm yam. Txawm li cas los xij, peb txoj kev tsim, UOE, RBE, thiab JCOE, tau siv dav.

1. UOE txoj kev sib sau: UOE steel yeeb nkab chav tsim txheej txheem muab faib ua peb kauj ruam kom ua tiav, uas yog ua ntej khoov, U-shaped xovxwm sib sau, thiab O-shaped xovxwm sib sau, ua raws li txias expansion ntawm tag nrho cov yeeb nkab kom tshem tawm cov yeeb nkab. ua txheej txheem Qhov kev ntxhov siab tshwm sim. Lub tsev tsim muaj cov cuab yeej loj thiab tus nqi siab. Txhua txheej txheej txheej yuav tsum tau nruab nrog ntau lub casing puab thiab sab welders, uas muaj ntau lawm efficiency. Vim yog qhov profileing, nrog cov cuab yeej tsim ntau dua, cov yeeb nkab steel ntawm ib txoj kab uas hla xav tau cov txheej txheem tsim pwm, thiab cov pwm no yuav tsum tau hloov thaum hloov cov khoom specifications. Qhov kev ntxhov siab sab hauv ntawm cov yeeb nkab welded yog qhov loj, thiab nws feem ntau nruab nrog lub tshuab nthuav dav. UOE chav tsev muaj cov cuab yeej paub tab, qib siab ntawm automation, thiab cov khoom siv txhim khu kev qha, tab sis chav tsev muaj peev txheej loj hauv cov cuab yeej siv, uas tsim nyog rau kev tsim cov khoom ntim loj.

2. RBE txoj kev tsim: Cov theem ntawm RBE txoj kev yog dov, dabtsi yog khoov, thiab txoj kab uas hla expansion. Cov txheej txheem ntau lawm yog mature. Yav dhau los, RB feem ntau yog siv los tsim cov hlab ntsha siab, cov qauv hlau, thiab cov kav dej thiab cov kav dej uas muaj qhov loj dua sab nraud thiab qhov ntev. Vim tias cov lag luam zoo tib yam tsis tuaj yeem dais qhov peev loj ntawm UOE yeeb nkab ua chav tsev, RBE yeeb nkab ua chav tsim tsim raws li RB muaj cov yam ntxwv ntawm kev nqis peev me me, nruab nrab batch, yooj yim cov khoom specification, thiab lwm yam, yog li nws tau tsim sai heev. Cov welded yeeb nkab uas tsim los ntawm cov txheej txheem tsim no yog ze rau UOE steel yeeb nkab nyob rau hauv cov nqe lus thiab kev ua tau zoo, yog li nws tuaj yeem hloov UOE welded yeeb nkab feem ntau. RBE yeeb nkab ua chav tsev siv peb-yob dov kom ua tiav cov yeeb nkab steel. Cov txheej txheem ua yeeb nkab yog qhov peb-yob txoj kev tshuab yob lub phaj steel rau hauv cov yeeb nkab steel nrog lub caliber, thiab tom qab ntawd siv cov yob txoj kev los khoov ntug ntawm cov yeeb nkab steel. , Thiab ces khoov ntug nrog ib tug sib sau yob los yog backbend. Vim nws yog peb-yob nruam yob dabtsi yog khoov txoj kev, qhov kev nyuaj siab faib generated thaum lub sij hawm steel yeeb nkab txoj kev yog ib tug sib xws. Txawm li cas los xij, thaum hloov cov khoom specifications, nws yog ib qho tsim nyog yuav tsum tau hloov cov tub ntxhais yob thiab kho cov yob qis kom tsim nyog. Ib txheej ntawm cov rolls tseem ceeb ntawm cov cuab yeej tsim tuaj yeem coj mus rau hauv tus account cov khoom ntawm ntau qhov tshwj xeeb. Qhov tsis zoo yog qhov kev tsim khoom me me, thiab cov phab ntsa tuab thiab txoj kab uas hla ntawm cov yeeb nkab steel raug txwv zoo heev vim muaj kev cuam tshuam ntawm lub zog thiab rigidity ntawm cov tub ntxhais cov tub ntxhais.

3. JCOE txoj kev sib sau: JCOE txoj kev muaj peb theem, uas yog, cov hlau phaj yog thawj zaug nias rau hauv J hom, thiab ces nias rau hauv C duab thiab O zoo nyob rau hauv lem. E stands rau txoj kab uas hla expansion. JCOE txoj kev tsim cov yeeb nkab tsim yog tsim los ntawm UOE txoj kev tsim. Nws kawm los ntawm lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm U-puab thiab tso tawm thiab ua raws li cov txheej txheem UOE, uas txo cov tonnage ntawm lub tshuab tsim thiab txuag cov cuab yeej siv. Cov yeeb nkab steel uas tsim tawm yog tib yam li UOE welded yeeb nkab, tab sis cov zis qis dua UOE welded yeeb nkab chav tsev. Cov txheej txheem no yooj yim kom paub txog kev tswj tsis siv neeg hauv cov txheej txheem tsim, thiab cov khoom zoo li qub. JCOE cov cuab yeej tsim tuaj yeem muab faib ua ob hom, ib qho yog dabtsi yog khoov, lwm qhov yog compression forming. Bending txoj kev yog tsuas yog siv nyob rau hauv kev tsim cov txheej txheem ntawm tuab thiab nruab nrab-tuab daim hlau, nrog rau cov kauj ruam me me thiab cov zis qis dua. Cov txheej txheem tsim yog dov ob lub npoo ntawm lub phaj steel rau hauv ib qho arc ntawm lub tshuab dabtsi yog khoov raws li lub vojvoog ntawm curvature ntawm cov yeeb nkab welded, thiab tom qab ntawd siv lub tshuab tsim los nias ib nrab ntawm cov hlau phaj rau hauv C zoo los ntawm ntau yam. cov kauj ruam, thiab tom qab ntawd pib los ntawm lwm sab ntawm lub phaj hlau Nias, tom qab ntau lub kauj ruam nias, sab nraud ntawm lub phaj hlau kuj tseem nias rau hauv C duab, kom tag nrho cov hlau phaj dhau los ua qhov qhib O zoo ntawm qhov chaw.
