Welded Steel Yeeb: Cov Kev Qhia Txog Kom Ua Kom Tau Zoo thiab Txhim Kho Kev Zoo
Qhia:
Nyob thoob plaws kev lag luam, cov kav hlau steel tau siv ntau yam rau lawv lub zog, kav ntev, thiab versatility. Thaum koom nrog cov kav hlau steel, vuam yog txoj kev nyiam. Vuam tsim cov kev sib txuas muaj zog uas tuaj yeem tiv thaiv qhov siab siab, ua rau nws tsis tseem ceeb hauv cov haujlwm xws li kev tsim kho, roj thiab kev tsim khoom. Hauv cov blog no, peb yuav dhia mus rau qhov tseem ceeb ntawm cov yeeb nkab steel hlau vuam thiab muab cov kev qhia dav dav kom ua kom muaj kev sib txuas tau zoo thiab txhim khu kev qha

Hydrostatic Kev Ntsuam Xyuas
Txhua qhov ntev ntawm cov yeeb nkab yuav tsum raug sim los ntawm cov khw mus rau lub tshuab cua hydostatic Lub siab yuav tsum txiav txim siab los ntawm kab sib luag hauv qab no:
P = 2st / d
Kev tso cai sib txawv hauv qhov hnyav thiab qhov ntev
Txhua qhov ntev ntawm cov yeeb nkab yuav tsum tau sib cais thiab nws qhov hnyav yuav tsis sib txawv ntau dua 10% dhau los yog nws qhov hnyav, suav siv nws qhov ntev thiab qhov hnyav rau ib ntu ntev.
Cov taub sab nraud yuav tsis sib txawv ntau dua ± 1% los ntawm cov kev cai tshwj xeeb sab nraud ntawm lub taub.
Phab ntsa tuab ntawm txhua qhov taw tes yuav tsum tsis ntau tshaj 12.5% nyob rau hauv cov phab ntsa dicently.
Qho ntev
Ib Leeg Random ntev: 16 txog 25ft (4.88 txog 7.62m)
Ob chav random ntev: ntau dua 25ft rau 35ft (7.62 txog 10.67m)
Uniform ntev: kev tiv thaiv kev sib tw ± 1in
Xaus
Cov yeeb nkab nqa yuav tsum tau muab cov ntaub nyias nyias xaus, thiab cov burrs ntawm qhov kawg yuav raug tshem tawm
Thaum cov yeeb nkab kawg tau teev tseg rau Bevel xaus, lub kaum sab xis yuav yog 30 txog 35 degree
1. Tag nrho cov kav dej steel:
Hlau Kav HlauLos ntawm ntau yam ntawm ntau thiab tsawg thiab cov ntaub ntawv, txhua haum rau cov ntawv thov tshwj xeeb. Lawv feem ntau yog ua los ntawm cov roj carbon hlau, hlau steel lossis alloy steel. Carbon Steel Kav yog siv dav siv vim lawv cov nqi pheej yig thiab lub zog, thaum stainless kav kav muaj cov khoom siv corrosion zoo heev. Nyob rau hauv qhov chaw kub ib puag ncig, alloy steel kav yog nyiam. Nkag siab txog ntau hom sib txawv ntawm cov yeeb nkab steel yuav pab txiav txim siab qhov kev xaiv vuam tsim nyog.
2. Xaiv cov txheej txheem vuam:
Muaj ntau yam vuam cov txheej txheem siv los koom nrog cov yeeb nkab steel, suav nrog cov roj vuam muag hlau) vuam, mig (motal inert roj) vuam, thiab submerged arc vuam. Kev xaiv ntawm cov txheej txheem vuam yog nyob ntawm cov khoom siv xws li hlau hom, yeeb nkab taub, vuam qhov chaw thiab tsim qauv sib koom tes. Txhua txoj kev muaj qhov zoo thiab cov kev txwv thiab xaiv cov txheej txheem tsim nyog tshaj plaws rau cov ntawv thov xav tau yog qhov tseem ceeb.
3. Npaj cov yeeb nkab steel:
Kev npaj kom raug cov yeeb nkab ua ntej vuam yog qhov tseem ceeb kom ua tiav lub zog muaj zog thiab txhim khu kev qha. Nws cuam tshuam nrog kev tu cov yeeb nkab saum npoo kom tshem tawm cov xeb, nplai lossis paug. Qhov no tuaj yeem ua tiav los ntawm cov txheej txheem tu tshuab xws li xaim txhuam hniav lossis sib tsoo, lossis kev siv tshuaj ntxuav tshuaj. Tsis tas li ntawd, chamfering cov yeeb nkab kawg tsim v-puab groove uas tso cai rau cov khoom siv ua tub lim, yog li ua rau cov txheej txheem vuam.
4. VUAM TSHUAB XYOO:
Cov txheej txheem vuam siv cuam tshuam rau qhov zoo ntawm kev sib koom ua ke. Ua raws li cov txheej txheem vuam siv, tsim nyog tsis sib xws xws li vuam tam sim no, hluav taws xob, kev tawm tshiab yuav tsum raug tswj. Qhov kev txawj thiab kev paub ntawm cov welder kuj playder kuj yog lub luag hauj lwm tseem ceeb hauv kev ua tiav qhov zoo thiab muaj kev ywj pheej weld. Cov tswv yim xws li kev ua haujlwm electrode, tswj tau cov roj ruaj khov, thiab ua kom muaj kev phom sij txaus los tiv thaiv kev tsis xws luag los yog tsis muaj fusion.
5. Ncej Kev Soj Ntsuam Xyuas Weld:
Thaum lub vuam ua tiav, nws yog qhov tseem ceeb rau kev kuaj xyuas tom qab Weld soj ntsuam kom pom qhov tsis txaus ntseeg lossis qhov khuam uas tuaj yeem ua rau muaj kev sib koom ua ke. Cov kev kuaj sim tsis yog kev soj ntsuam xws li kev tshuaj xyuas pom, zas kev kuaj mob, sib nqus particle kuaj lossis ultrasonic kuaj yuav siv tau. Cov kev tshuaj xyuas no pab txheeb xyuas cov teeb meem muaj peev xwm thiab ua kom pom tseeb tias welded pob qij txha ua tau raws li cov lus qhia tshwj xeeb.
Hauv kev xaus:
Steel yeeb nkab rau vuamyuav tsum tau txais kev ua tib zoo saib xyuas thiab raug tua kom ntseeg tau tias muaj kev sib txuas tau zoo thiab txhim khu kev qha. Los ntawm kev nkag siab cov yeeb nkab sib txawv, xaiv cov khaub ncaws vuam tsim nyog, siv cov tshuaj vuam, koj tuaj yeem ua tiav cov ntaub ntawv weld, koj tuaj yeem ua tiav cov khoom siv vuam zoo thiab muaj zog. Qhov no nyob rau hauv cov kev hloov yuav pab kev nyab xeeb, kev cia siab thiab kev pabcuam lub neej ntawm cov kav hlau hauv ntau yam uas lawv yog cov khoom tseem ceeb.
