Vim li cas nws hu ua Submerged Arc Vuam?

Submerged Arc Vuam (pom) yog siv vuam vuam hauv kev lag luam vuam, paub txog nws qhov kev ua haujlwm siab thiab ruaj khov. Rau cov tshiab rau vuam thev naus laus zis, ib qho lus nug tshwm sim: vim li cas nws hu ua "submerged arc vuam"? Qhov no zoo li yooj yim naming yeej muaj cov yam ntxwv tseem ceeb ntawm thev naus laus zis, pom cov qauv kev ua haujlwm ntawm cov qauv vuam vet.
Tus thawj coj rau lub npe: "submerged" lub xeev ntawm arc
Tus yuam sij los teb cov lus nug no nyob hauv kev nkag siab cov txheej txheem ua haujlwm ntawm submerged arc vuam. Tsis zoo li lwm cov vuam txoj kev vuam xws li Shield worded hlau vuam (qhov twg arc yog qhov pom ntawm lub ntsej muag), lub arc yog ib nrab ntawm lub arc vuam yog nyob rau hauv lub xeev zais cia thaum lub sij hawm vuam.
Tshwj xeeb, ua ntej vuam pib, granular flux yog pre {0} {laids txheej, sib sau flux txheej nrog ib tug tuab ntawm feem ntau 20-50mm. Thaum lub zog vuam tig rau, chaw hlau vuam (uas cov khoom noj txuas ntxiv mus rau hauv qhov chaw vuam) thiab cov hlau hauv paus yog ionized los tsim lub arc. Nyob rau lub sijhawm no, ARC tsis raug rau huab cua tab sis yog qhwv tag rau hauv txheej flux. Qhov kub ntawm lub arc melts lub vuam hlau, ntawm lub hauv paus hlau, thiab ib feem ntawm flux txheej, uas txuas ntxiv npog Arc thiab lub pas dej Molten.
Qhov no "arc yog qhwv los ntawm flux thiab slag" yog qhov ua tau zoo tshaj plaws ntawm "submerged". Ib yam li tus dhia dej tau submerged nyob rau hauv dej, arc nyob rau hauv submered arc vuam yog "nyob rau hauv nruab nrab (flux), yog li nws tau npe" submerged arc vuam ".
Txoj haujlwm ntawm "submersion": vim li cas cov arc xav tau zais
Lub "Submerged" Lub xeev ntawm ARC tsis yog kev ntsuas random tab sis efficiency kom ntseeg tau tias vim li cas thiaj li siv tau dav.
1. Kev tiv thaiv zoo meej tiv thaiv cov kev ua paug atmosphricer
Cov flux thiab cov shell tsim tom qab cov ntawv melting ib qho chaw ua rau lub cev ntom nti, Molten pas dej, thiab high {{{{{} kub kub weld hlau los ntawm huab cua. Qhov no txwv tsis pub muaj kev phom sij hauv huab cua (xws li oxygen, thiab hydrogen, thiab nitrogen, thiab nitrogen, thiab nitridation ntawm Weld, txo nws txoj kev nruj me; Hydrogen yog lub ntsiab ua rau vuam sib tsoo. Nyob rau hauv submered arc vuam, vim yog "submerged" tiv thaiv "tiv thaiv tus kheej cov ntsiab lus qis, thiab qhov tshwm sim ntawm cov kab mob hauv qab thiab cov kab nrib pleb yog txo qis rau arc vuam txoj kev.
2. Cov arc yooj yim thiab cua sov
Flux txheej tuaj yeem siv lub arc. Tsis zoo li lub arc nyob rau hauv qhib vuam (uas yog yooj yim ntxhov siab los ntawm huab cua txaus "hauv flux yog tsawg dua los ntawm cov huab cua sab nraud los yog kev co kom nruj. Nyob rau tib lub sijhawm, Flux muaj qee cov txiaj ntsig thermal rwb thaiv tsev, txo cov cua sov thaum lub sijhawm vuam. Qhov no tso cai rau cov cua sov tsim los ntawm arc kom muaj ntau lub siab xav ua kom yaj, uas yog qhov ua kom muaj cov hlau ua kom zoo nkauj thiab txhim kho vuam ua haujlwm.
3. Txo ntawm lub ntsej muag thiab pa ncho
Txhawm rau hauv arc vuam, siab {{{}} Cov kua kub yooj yim nyob ib ncig ntawm arc, ua rau cov khoom pov tseg thiab muaj peev xwm kev nyab xeeb nyab xeeb. Nyob rau hauv submered arc vuam, flux txheej "cov ntxiab" lub ntsej muag- Feem ntau ntawm cov khaub ncaws Molten Tsis tas li ntawd, cov flux nqus tau feem ntau ntawm cov pa luam yeeb thiab cov teeb meem roj tsim hluav taws xob, ua kom ib puag ncig ua haujlwm chav ntxuav.
Qhov sib txawv los ntawm lwm txoj kev vuam: Qhia txog cov yam ntxwv ntawm "submersion"
Txhawm rau kom nkag siab zoo dua qhov tsis zoo ntawm "Arc
Cov thaiv hlau arc vuam (smaw)
Hauv smaw, lub arc hlawv ntawm electrode thiab lub hauv paus hlau, thiab txawm tias cov hlau hluav taws xob tsim hluav taws xob tsim hluav taws xob roj teeb ua ke, arc nws tus kheej yog ib nrab raug rau huab cua. Thaum lub sij hawm vuam ua haujlwm, ARC tuaj yeem pom ncaj qha nrog lub qhov muag liab qab, uas yog txawv ntawm cov arc uas zais tag nrho nyob rau hauv submerged arc vuam.
Gas Hlau Arc Vuam (Gmaw)
GMAW siv cov roj ntsha (xws li argon) lossis xws li argon + carbon dioxide) los tiv thaiv lub arc thiab molten pas dej. ARC yog nyob rau hauv ib puag ncig roj, thiab txawm hais tias nws tsis nyob rau hauv cov huab cua, nws tseem nyob rau hauv ib lub xeev "raug pob tshab, thiab arc tuaj yeem pom). Tsis muaj qhov tsis muaj flux txheej los qhwv lub arc, yog li nws tsis muaj qhov "submerged".
Flux -} cored arc vuam (FCAW)
FCAW siv flux - Cored hlau, thiab flux sab hauv cov hlau yaj los ua tus tiv thaiv kab mob. Txawm li cas los xij, nws arc tsuas yog them los ntawm shag, thiab feem ntau ntawm nws tseem raug. Ntxiv mus, flux hauv fcaw yog sab hauv lub xaim, thiab tsis muaj ua ntej} laid flux vuam, yog li lub arc tsis tau "submerged".
Nws yog qhov meej meej vim tias muaj tshwj xeeb "Arc yog qhwv tag nrho" uas cov npe ntawm cov qauv sib txawv ntawm lwm txoj kev sib txawv.
Qhov tseem ceeb ntawm Naming: Tshaj tawm thiab ua kom zoo dua VUAM TSHUAB
Lub npe ntawm "submerged arc vuam" tsis tsuas yog piav qhia qhov tshwm sim intuitively tab sis kuj muaj qhov tseem ceeb rau kev ua tau zoo thiab ua rau thev naus laus zis.
Rau cov pib tshiab hauv vuam, lub npe no tuaj yeem tsim kev sib txuas sai ntawm cov qauv no yog qhov zais ntawm cov qauv ntawm txoj kev ua haujlwm thiab kev ua haujlwm tiv thaiv kev ua haujlwm. Rau cov kws txua khoom thiab cov kws tshaj lij, lub npe yog cov qauv sib xws, cov duab kos, thiab cov txheej txheem, zam kev tsis txaus ntseeg.
Tsis tas li ntawd, qhov no Naming kuj qhia txog lub logic ntawm Engineering Technology Naming - feem ntau raws li cov yam ntxwv tshaj plaws. Ib yam li "cov roj thaiv cov hluav taws xob vuam" muaj npe tom qab lub arc vuam "siv lub cim" ntawm lub arc raws li tus tub ntxhais yooj yim los txheeb xyuas thiab nco ntsoov.
Xaus: Lub npe uas condenses technical essence
Hauv cov ntsiab lus, lub npe "Submerged Arc Vuam" los ntawm nws txheej txheem flux thiab sluc yog cov txheej txheem vuam thaum lub sij hawm "submerged" xeev. Lub xeev no tsis yog tsuas yog tus yam ntxwv pom tseeb tab sis kuj yog tus yuam sij los ua kom muaj kev ua tau zoo, muaj txiaj ntsig zoo, thiab tsis muaj kuab paug ntawm cov thev naus laus zis.
Nkag siab lub keeb kwm ntawm lub npe no tsis yog tsuas yog cov lus qhuab qhia tab sis kuj tseem yuav pab ua kom tau txais kev ua haujlwm ntawm submergle arc vuam vuam. Rau kev tsim khoom lag luam, qhov no "submerged" arc coj kev txhim khu kev qha welds thiab ntau lawm; Rau kev lag luam vuam, lub npe no yog ib tug tseeb cov cim ntawm cov yam ntxwv ntawm thev naus laus zis. Nws tuaj yeem hais tias "submerged arc vuam" yog kev sib xyaw ua ke zoo tag nrho ntawm kev ua ke ntawm cov qauv technicals thiab tis npe kos duab.
