Dab tsi yog ob tog submerged arc welded steel yeeb nkab?
Ob chav sided submerged arc vuam steel yeeb nkab yog ib hom steel yeeb nkab ua los ntawm ob sab submerged arc vuam txheej txheem. Tshwj xeeb, cov txheej txheem vuam ntawm cov yeeb nkab steel no yog submerged arc vuam nyob rau sab hauv thiab sab nraud ntawm cov yeeb nkab steel tib lub sijhawm kom ntseeg tau qhov kev ntseeg siab thiab zoo ntawm cov vuam. Hauv qab no yog cov lus piav qhia ntxaws ntxaws ntawm ob sab submerged arc vuam steel yeeb nkab:
一,vuam tshuab
Submerged arc vuam: Submerged arc vuam yog ib txoj kev vuam uas cov arc kub hnyiab tau nyob rau hauv cov txheej txheem flux, nrog kev ruaj khov thiab txhim khu kev qha vuam zoo, siab vuam efficiency thiab zoo nkauj weld tsim. Nyob rau hauv kev tsim cov ob-sided submerged arc vuam steel yeeb nkab, vuam hlau txuas txuas txuas mus rau qhov chaw vuam los ntawm cov khoom siv hlau tsis siv neeg, thiab melted nrog lub hauv paus hlau ntawm cov yeeb nkab steel nyob rau hauv kev tiv thaiv flux los tsim ib tug weld.
Muab ob npaug rau-sided vuam: Muab piv nrog ib leeg-sab vuam, ob sab vuam tuaj yeem txhim kho lub zog thiab sib khi ntawm vuam. Nyob rau hauv ob-sided submerged arc welded steel yeeb nkab, lub vuam tsis yog tsuas yog tsim rau sab nraud, tab sis kuj nyob rau hauv, yog li ua tiav cov kev pab cuam weld.
2,Khoom nta
Lub zog siab: vim yog kev siv cov hlau zoo thiab cov cuab yeej siv vuam zoo heev, ob tog submerged arc welded steel kav muaj lub zog tensile siab thiab lub zog tawm los.
Kev ua tau zoo sealing: Lub welded seam ntawm ob sab welding muaj cov qauv compact thiab tsis muaj qhov tsis xws li cua qhov thiab slag suav nrog, uas ua kom lub sealing kev ua tau zoo ntawm cov yeeb nkab steel.
orrosion kuj: raws li tus neeg siv yuav tsum tau, qhov saum npoo ntawm cov yeeb nkab steel tuaj yeem kho nrog kev tiv thaiv corrosion, xws li zinc plating thiab yas txheej, los txhim kho nws cov corrosion kuj.
High dimensional precision: nruj me ntsis tswj thiab tshuaj xyuas yog ua nyob rau hauv cov txheej txheem ntau lawm los xyuas kom meej tias qhov seem ntawm cov yeeb nkab steel ua tau raws li qhov yuav tsum tau ua.
3,daim ntawv thov cheeb tsam
Ob chav sided submerged arc welded steel kav yog dav siv nyob rau hauv ntau lub teb vim lawv cov khoom zoo heev:
Architectural teb: Nws yog siv rau load-bearing kab, kab teeb thiab lwm yam nyob rau hauv lub tsev, thiab ua tau raws li tus tsim yuav tsum tau ntawm ntau yam duab los ntawm txias dabtsi yog khoov.
Choj engineering: Raws li cov qauv kev txhawb nqa thiab kev taw qhia ntawm tus choj, nws muaj peev xwm ua tau zoo thiab kev ua haujlwm seismic.
Kev lag luam Petrochemical: siv rau kev xa cov roj, roj av thiab lwm yam kua dej, kom ua tau raws li qhov xav tau ntawm kev nkhaus hauv cov txheej txheem tso dej thiab txhim kho kev ruaj ntseg thiab kev sib khi ntawm cov kav dej.
4, txheej txheem ntau lawm
Cov txheej txheem tsim khoom ntawm ob sab submerged arc welded steel yeeb nkab feem ntau suav nrog cov kauj ruam hauv qab no:
Kev npaj cov khoom siv raw: xaiv cov hlau tsim nyog raws li cov khoom siv raw. Kev tsim: cov hlau nyoos yog ua tiav rau hauv lub raj khoob nrog ib qho duab los ntawm lub tshuab sib sau.
Pre-welding: Pre-welding lub raj dawb paug los npaj rau tom ntej submerged arc vuam.
Ob sab submerged arc vuam: submerged arc vuam yog nqa tawm ntawm sab hauv thiab sab nraud ntawm lub raj khoob tib lub sijhawm.
Weld soj ntsuam: ultrasonic thiab X-ray tshuaj xyuas yuav tsum tau ua los xyuas kom meej lub weld zoo.
Kev kho tom qab: suav nrog kev nthuav dav, kev sim hydrostatic, kev kho corrosion thiab lwm cov kauj ruam los txhim kho kev ua tau zoo thiab kev pabcuam lub neej ntawm cov kav dej steel.
Yuav kom suav tau, ob-sided submerged arc welded steel yeeb nkab yog ib hom steel yeeb nkab khoom nrog kev ua tau zoo heev thiab daim ntawv thov dav.
