Kauv welded steel yeeb nkab (SSAW steel yeeb nkab),Kauv submerged arc yeeb nkab
Kauv steel yeeb nkab, tseem hu ua kauv welded yeeb nkab, yog tsim los ntawm dov qis - carbon structural steel los yog qis- alloy structural steel sawb rau hauv ib lub raj khoob ntawm ib lub kaum ntse ntse (hu ua lub kaum sab xis), thiab tom qab ntawd welding lub raj seams. Nws tuaj yeem tsim loj - txoj kab uas hla steel kav nrog nqaim strip steel.
Nta:
Cov txheej txheem ntau lawm ntawm txoj hlua ncaj nraim welded yeeb nkab (ERW / LSAW) yog qhov yooj yim, nrog kev ua haujlwm siab, tus nqi qis thiab kev loj hlob sai. Lub zog ntawm kauv welded yeeb nkab feem ntau yog siab tshaj qhov ncaj seam welded yeeb nkab. Nws tuaj yeem tsim cov welded kav nrog cov kab uas loj dua nrog cov kab nqaim, thiab tseem tuaj yeem tsim cov kav dej sib txawv nrog cov kab sib txawv nrog cov pob zeb ntawm tib qhov dav. Txawm li cas los xij, piv nrog cov kav dej ncaj nraim ntawm tib qhov ntev, qhov ntev ntawm qhov vuam nce los ntawm 30 ~ 100%, thiab qhov ceev ntau lawm yog qis dua. Yog li ntawd, feem ntau me me txoj kab uas hla welded kav siv ncaj seam vuam, thaum loj txoj kab uas hla welded kav feem ntau siv kauv vuam.

SSAW steel yeeb nkab yog cov khoom siv raw ntawm sawb kauj, feem ntau kub extrusion molding, tsis siv neeg ob - hlau ob chav submerged arc vuam txheej txheem ua los ntawm kauv seam yeeb nkab. Kauv steel yeeb nkab yuav strip rau hauv cov yeeb nkab chav tsev, ntau - yob dov, strip dov, ua ib ncig qhov sib txawv qhib qhov sib txawv, kho qhov nyem yob txo, qhov sib txawv weld tswj nyob rau hauv 1 ~ 3 hli, thiab ua rau ob qho kawg ntawm cov weld flush.
Kev tsim cov txheej txheem ntawm SSAW steel yeeb nkab:
(1) Cov ntaub ntawv raw yog sawb steel kauj, vuam hlau thiab flux. Lawv yuav tsum tau kuaj xyuas lub cev thiab tshuaj nruj ua ntej muab tso rau hauv kev siv.
(2) Lub taub hau thiab tus Tsov tus tw ntawm lub sawb hlau yog pob tw - sib koom ua ke los ntawm ib leeg - hlau los yog ob npaug - hlau submerged arc vuam. Tom qab dov mus rau hauv cov yeeb nkab steel, tsis siv neeg submerged arc vuam yog siv los kho vuam.
(3) Ua ntej kev tsim, cov hlau sawb yog leveled, trimmed, planed, deg huv si, conveyed thiab pre-bent.
(4) Lub tshuab hluav taws xob sib txuas yog siv los tswj lub siab ntawm lub tog raj kheej roj ntawm ob sab ntawm cov khoom siv los xyuas kom meej qhov kev sib tw ntawm cov sawb hlau.
(5) Kev tswj sab nraud lossis sab hauv tswj cov menyuam txoj kev yog saws.
(6) Cov khoom siv vuam sib txawv yog siv los xyuas kom meej tias qhov sib txawv ntawm qhov vuam ua tau raws li qhov xav tau ntawm vuam. Cov yeeb nkab txoj kab uas hla, misalignment thiab weld gap yog nruj me ntsis tswj.
(7) Ob qho tib si sab hauv thiab sab nraud yog ua los ntawm ib qho - hlau los yog ob npaug - hlau submerged arc vuam siv American Lincoln hluav taws xob welder kom tau txais cov khoom siv vuam ruaj khov.
(8) Tag nrho cov welds raug tshuaj xyuas los ntawm online txuas ntxiv ultrasonic tsis siv neeg qhov tsis pom kev kom ntseeg tau 100% tsis yog -kev ntsuas kev puas tsuaj ntawm cov kauv welds. Yog tias muaj teeb meem, lub tswb tsis siv neeg yuav raug suab thiab lub cim yuav raug tshuaj tsuag. Cov neeg ua haujlwm tsim khoom tuaj yeem kho cov txheej txheem tsis tu ncua txhua lub sijhawm kom tshem tawm qhov tsis xws luag hauv lub sijhawm.
(9) Cov kav hlau steel raug txiav rau hauv ib qho los ntawm lub tshuab cua plasma.
(10) Tom qab txiav rau hauv ib leeg cov kav hlau, txhua pawg ntawm cov kav hlau yuav tsum tau ua raws li kev soj ntsuam nruj me ntsis txhawm rau xyuas cov khoom siv kho tshuab, tshuaj lom neeg muaj pes tsawg leeg, fusion txheej txheem, qhov zoo ntawm cov welds thiab tsis yog -kev sim ua kom puas tsuaj los xyuas kom meej tias cov yeeb nkab ua cov txheej txheem tsim nyog ua ntej nws tuaj yeem raug muab tso rau hauv ntau lawm.
(11) Cov khoom uas muaj cov cim tsis zoo ntawm cov welds txuas mus ntxiv yog rov- tshuaj xyuas los ntawm phau ntawv ultrasonic thiab X-ray. Yog tias muaj qhov tsis xws luag, lawv raug kho thiab tom qab ntawd raug rau qhov tsis yog - kev sim ua kom puas tsuaj dua kom txog thaum nws tau lees paub tias qhov tsis xws luag tau raug tshem tawm.
(12) Lub pob tw welds ntawm lub sawb hlau thiab cov kav dej uas T- sib txuas nrog cov kauv welds yog txhua yam tshuaj xyuas los ntawm X-ray TV lossis zaj duab xis.
(13) Txhua cov yeeb nkab steel yog raug rau kev sim hydrostatic, thiab lub siab yog radially kaw. Kev ntsuas siab thiab lub sijhawm yog nruj me ntsis tswj los ntawm cov yeeb nkab steel dej siab microcomputer tshawb pom cov cuab yeej. Cov ntsuas ntsuas tau raug luam tawm thiab kaw.
(14) Cov yeeb nkab kawg yog machined kom raug tswj qhov kawg lub ntsej muag verticality, zawj lub kaum sab xis thiab blunt ntug.
