Submerged arc vuam yog qhov zoo tagnrho rau cov kav xa dej, cov hlab ntsha siab thiab cov tso tsheb hlau luam, kev tsim kev tsheb ciav hlau thiab kev siv loj, nrog rau daim ntawv monofilament yooj yim tshaj plaws, ob chav xaim qauv, tandem ob chav xaim qauv thiab ntau cov qauv.
Submerged arc vuam tuaj yeem muaj txiaj ntsig rau cov neeg siv hauv ntau daim ntawv thov vuam.Los ntawm kev ua kom cov khoom tsim tau zoo, txhim kho qhov chaw ua haujlwm, kom ntseeg tau zoo ib yam thiab ntau dua.Hlau ua fabricators uas tab tom xav txog kev hloov pauv hauv cov txheej txheem submerged arc vuam yuav tsum tau xav tias lawv tuaj yeem tau txais txiaj ntsig ntau ntawm cov txheej txheem no.
Kev paub yooj yim ntawm submerged arc vuam
Cov txheej txheem submerged arc vuam yog qhov yuav tsum tau ua rau cov khoom siv hnyav xws li cov kav dej, cov hlab ntsha thiab cov tso tsheb hlau luam, kev tsim kho tsheb, kev tsim kho hnyav / khawb.Qhov zoo tshaj plaws rau kev lag luam uas xav tau cov khoom lag luam siab, tshwj xeeb tshaj yog thaum nws los txog rau vuam cov ntaub ntawv tuab heev, muaj ntau yam txiaj ntsig uas yuav tau txais los ntawm submerged arc vuam txheej txheem.
Nws qhov kev tso nyiaj siab thiab kev taug kev ceev tuaj yeem muaj kev cuam tshuam loj rau cov neeg ua haujlwm tsim khoom, kev ua haujlwm zoo thiab cov nqi tsim khoom, uas yog ib qho ntawm cov txiaj ntsig tseem ceeb ntawm submerged arc vuam txheej txheem.
Lwm cov txiaj ntsig suav nrog: Cov tshuaj lom neeg muaj pes tsawg leeg zoo heev thiab cov khoom siv ntawm cov khoom siv vuam, qhov pom qhov tsawg kawg nkaus arc thiab cov pa vuam tsis tshua muaj, txhim kho kev ua haujlwm ib puag ncig, thiab zoo weld zoo thiab cov ntiv taw kab.
Submerged arc vuam yog ib txoj hlua pub mis uas siv granular flux los cais cov arc ntawm huab cua, raws li lub npe qhia, lub arc yog faus rau hauv lub flux, uas txhais tau hais tias thaum tsis muaj teeb meem, lub arc yog tsis pom nrog lub outflow ntawm. ib txheej ntawm flux.Lub vuam hlau yog pub tsis tu ncua los ntawm ib lub teeb uas txav raws qhov vuam.
Arc cua sov melts ib feem ntawm cov hlau, ib feem ntawm cov flux thiab lub hauv paus hlau, tsim ib tug molten pas dej ua ke, uas condenses rau ib tug weld npog nrog ib tug txheej ntawm vuam slag.Qhov tuab ntawm cov khoom siv vuam yog 1/16 "-3/4", tuaj yeem yog 100% kev nkag mus vuam los ntawm ib qho vuam, yog tias cov phab ntsa tuab tsis txwv, ntau qhov vuam tuaj yeem ua tau, thiab cov vuam yog tsim nyog pretreated thiab xaiv, thiab qhov tsim nyog vuam hlau flux ua ke raug xaiv.

Kev xaiv ntawm flux thiab vuam hlau
Xaiv txoj cai flux thiab xaim rau ib qho tshwj xeeb submerged arc vuam txheej txheem yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig zoo tshaj plaws uas siv cov txheej txheem.Txawm hais tias submerged arc vuam txheej txheem ib leeg yog qhov ua tau zoo, kev tsim khoom thiab kev ua tau zoo tuaj yeem nce ntxiv txawm tias raws li cov vuam hlau thiab flux siv.
Lub flux tsis tsuas yog tiv thaiv lub pas dej ua ke, tab sis kuj tseem txhawb kev txhim kho cov khoom siv kho tshuab thiab kev tsim khoom ntawm weld.Kev tsim cov fluxes muaj kev cuam tshuam loj heev rau cov xwm txheej no, cuam tshuam rau lub peev xwm nqa tam sim no thiab slag tso tawm.
Lub peev xwm nqa tam sim no txhais tau hais tias qhov ua tau zoo tshaj plaws ntawm kev tso nyiaj thiab cov khoom siv vuam zoo tuaj yeem tau txais.
Slag tso tawm los ntawm ib qho flux cuam tshuam rau kev xaiv flux vim tias qee qhov fluxes tsim nyog rau qee cov qauv tsim dua li lwm tus.
Flux xaiv xaiv rau submerged arc soldering muaj xws li nquag thiab nruab nrab hom welds.Ib qho tseem ceeb sib txawv yog tias cov active flux hloov cov chemistry ntawm weld, thaum lub nruab nrab flux tsis.
Active fluxes yog tus cwj pwm los ntawm kev suav nrog silicon thiab manganese.Cov ntsiab lus no pab tswj lub zog tensile ntawm weld ntawm high tshav kub input, pab kom lub weld du thiab du nyob rau hauv high school speeds thiab muab zoo slag tso.Zuag qhia tag nrho, active fluxes tuaj yeem pab txo qhov kev pheej hmoo ntawm cov khoom siv tsis zoo, nrog rau cov khoom kim heev tom qab vuam thiab rov ua haujlwm dua.Nco ntsoov, txawm li cas los xij, qhov nquag fluxes feem ntau yog qhov zoo tshaj plaws rau ib leeg-los yog ob-thooj soldering.
Neutral fluxes yog qhov zoo dua rau cov khoom siv loj loj vim tias lawv pab kom tsis txhob tsim cov nkig, tawg-rhiab welds.
Muaj ntau ntau hom vuam hlau xaiv txog submerged arc vuam, txhua qhov zoo thiab qhov tsis zoo.Qee cov xov hlau yog tsim los rau vuam ntawm cov khoom siv hluav taws xob ntau dua, thaum lwm tus yog tsim tshwj xeeb kom muaj cov hlau nplaum uas pab cov flux los ua vuam tu.
Nco ntsoov tias cov khoom siv tshuaj lom neeg thiab cov khoom siv hluav taws xob sib xyaw ua ke ntawm cov vuam hlau cuam tshuam rau cov khoom siv ntawm lub vuam.Productivity kuj tseem tuaj yeem nce ntxiv los ntawm kev xaiv hlau muab tub lim.
Piv txwv li, siv cov tub ntxhais hlau hlau nrog cov txheej txheem submerged arc welding tuaj yeem ua rau kom qhov kev ua tau zoo ntawm 15% mus rau 30% piv rau kev siv cov khoom siv hlau, thaum tseem muab qhov dav thiab qhov tob tob tob.
Vim nws txoj kev mus txawv tebchaws ceev, cov tub ntxhais hlau hlau tseem txo cov cua sov tawm kom txo tau qhov kev pheej hmoo ntawm vuam deformation thiab burnout.
Ntawm tag nrho cov hlau, austenitic stainless hlau muaj qhov qis tshaj tawm los.Yog li ntawd, nyob rau hauv cov nqe lus ntawm txhua yam khoom, austenitic stainless hlau tsis yog cov khoom zoo tshaj plaws rau lub valve qia, vim hais tias kom muaj ib tug tej yam lub zog, txoj kab uas hla ntawm lub valve qia yuav nce.Qhov taw tes tawm los tsis tuaj yeem nce los ntawm kev kho cua sov, tab sis nws tuaj yeem nce los ntawm kev ua kom txias.
Peb yog stockist ntawm carbon thiab stainless seamless steel yeeb nkab, txais tos cov lus nug, peb yuav muab thawj zaug!
