Kev vuam siv submerged arc yog qhov zoo tagnrho rau cov kav dej, cov hlab ntsha siab thiab cov tank, kev tsim tsheb ciav hlau thiab cov ntawv thov kev tsim kho loj, nrog rau daim ntawv monofilament yooj yim tshaj plaws, cov qauv hlau ob chav, cov qauv hlau ob chav thiab cov qauv ntau-filament.
Kev vuam hlau submerged arc tuaj yeem pab tau cov neeg siv hauv ntau daim ntawv thov vuam. Txij li kev ua haujlwm ntau ntxiv, mus rau kev txhim kho qhov chaw ua haujlwm, kom ntseeg tau tias muaj qhov zoo sib xws thiab ntau ntxiv. Cov neeg ua hlau uas tab tom xav txog kev hloov pauv hauv cov txheej txheem vuam hlau submerged arc yuav tsum tau xav tias lawv tuaj yeem tau txais ntau yam txiaj ntsig los ntawm cov txheej txheem no.
Kev paub yooj yim ntawm kev vuam submerged arc
Cov txheej txheem vuam submerged arc yog qhov yuav tsum tau ua rau cov ntawv thov kev lag luam hnyav xws li cov kav dej, cov hlab ntsha siab thiab cov thoob dej, kev tsim kho tsheb ciav hlau, kev tsim kho hnyav / kev khawb av. Zoo tagnrho rau cov lag luam uas xav tau kev tsim khoom siab, tshwj xeeb tshaj yog thaum nws los txog rau kev vuam cov ntaub ntawv tuab heev, muaj ntau yam txiaj ntsig los ntawm cov txheej txheem vuam submerged arc.
Nws qhov kev tso dej siab thiab kev taug kev ceev tuaj yeem muaj kev cuam tshuam loj rau kev ua haujlwm ntawm cov neeg ua haujlwm, kev ua haujlwm zoo thiab cov nqi tsim khoom, uas yog ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov txheej txheem vuam submerged arc.
Lwm cov txiaj ntsig suav nrog: muaj cov tshuaj lom neeg zoo heev thiab cov khoom siv kho tshuab ntawm qhov vuam, pom kev tsawg heev thiab cov pa phem tsawg ntawm qhov vuam, ua kom qhov chaw ua haujlwm xis nyob dua, thiab cov duab vuam thiab cov ntiv taw zoo.
Kev vuam siv submerged arc yog ib txoj kev pub hlau uas siv cov granular flux los cais cov arc ntawm huab cua, raws li lub npe qhia, cov arc raug faus rau hauv cov flux, uas txhais tau tias thaum cov kev teeb tsa tau teeb tsa, cov arc tsis pom nrog cov dej ntws ntawm ib txheej ntawm cov flux. Cov hlau vuam raug pub tas li los ntawm lub teeb uas txav mus raws qhov vuam.
Qhov cua sov arc yaj ib feem ntawm cov hlau, ib feem ntawm cov flux thiab cov hlau hauv paus, tsim cov pas dej molten, uas condenses los ua ib qho weld npog nrog ib txheej ntawm welding slag. Qhov tuab ntawm cov khoom siv vuam yog 1/16 "-3/4", tuaj yeem 100% nkag mus vuam los ntawm kev vuam ib zaug, yog tias qhov tuab ntawm phab ntsa tsis txwv, ntau-pass vuam tuaj yeem ua tiav, thiab qhov weld raug pretreated thiab xaiv kom raug, thiab cov hlau vuam flux sib xyaw ua ke raug xaiv.

Kev xaiv cov hlau flux thiab cov hlau vuam
Kev xaiv cov flux thiab hlau uas zoo rau ib qho txheej txheem vuam submerged arc yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig zoo tshaj plaws siv cov txheej txheem. Txawm hais tias cov txheej txheem vuam submerged arc ib leeg ua haujlwm tau zoo, kev tsim khoom thiab kev ua haujlwm zoo tuaj yeem nce ntxiv txawm tias nyob ntawm cov hlau vuam thiab flux siv.
Cov kua nplaum tsis yog tsuas yog tiv thaiv lub pas dej vuam xwb, tab sis kuj pab txhawb kev txhim kho cov khoom siv kho tshuab thiab kev tsim khoom ntawm lub vuam. Kev tsim cov kua nplaum muaj feem cuam tshuam loj heev rau cov yam no, cuam tshuam rau lub peev xwm nqa tam sim no thiab kev tso tawm slag.
Lub peev xwm nqa tam sim no txhais tau tias qhov ua tau zoo tshaj plaws ntawm kev tso dej thiab qhov zoo ntawm cov ntaub ntawv vuam tuaj yeem tau txais.
Kev tso tawm slag los ntawm ib qho flux tshwj xeeb cuam tshuam rau kev xaiv flux vim tias qee cov fluxes zoo dua rau qee qhov kev tsim solder dua li lwm tus.
Cov kev xaiv xaiv flux rau submerged arc soldering suav nrog cov hom welds nquag thiab neutral. Qhov sib txawv tseem ceeb yog tias cov active flux hloov pauv cov tshuaj lom neeg ntawm qhov vuam, thaum cov neutral flux tsis ua.
Cov kua nplaum nquag muaj cov yam ntxwv los ntawm kev suav nrog silicon thiab manganese. Cov ntsiab lus no pab tswj lub zog tensile ntawm qhov vuam ntawm qhov kub siab, pab ua kom qhov vuam du thiab du ntawm qhov nrawm nrawm thiab muab cov slag zoo. Zuag qhia tag nrho, cov kua nplaum nquag tuaj yeem pab txo qhov kev pheej hmoo ntawm qhov tsis zoo ntawm cov kua nplaum, nrog rau kev ntxuav thiab rov ua haujlwm tom qab vuam kim. Txawm li cas los xij, nco ntsoov tias cov kua nplaum nquag feem ntau yog qhov zoo tshaj plaws rau kev vuam ib zaug lossis ob zaug.
Cov kua dej tsis muaj zog zoo dua rau cov hlau nplaum loj ntau zaus vim tias lawv pab tiv thaiv kom tsis txhob muaj cov hlau nplaum tawg thiab tawg.
Muaj ntau hom hlau vuam xaiv txog kev vuam submerged arc, txhua tus muaj qhov zoo thiab qhov tsis zoo. Qee cov hlau yog tsim los rau kev vuam ntawm qhov kub siab dua, thaum lwm tus yog tsim tshwj xeeb kom muaj cov hlau sib xyaw uas pab cov flux ua haujlwm ntxuav vuam.
Nco ntsoov tias cov khoom siv tshuaj lom neeg thiab kev sib cuam tshuam ntawm cov hlau vuam cuam tshuam rau cov khoom siv kho tshuab ntawm qhov vuam. Kev tsim khoom kuj tseem tuaj yeem nce ntxiv los ntawm kev xaiv cov hlau filler.
Piv txwv li, siv cov hlau hlau uas muaj cov txheej txheem vuam submerged arc tuaj yeem ua rau kom muaj kev ua haujlwm ntawm cov dej ntws los ntawm 15% txog 30% piv rau kev siv cov hlau khov, thaum tseem muab cov qauv nkag mus dav dua thiab ntiav dua.
Vim nws qhov kev mus ncig ceev ceev, cov xov hlau tseem txo cov cua sov nkag los txo qhov kev pheej hmoo ntawm kev vuam deformation thiab hlawv.
Ntawm txhua cov hlau, cov hlau austenitic stainless hlau muaj qhov qis tshaj plaws. Yog li ntawd, hais txog cov khoom siv kho tshuab, cov hlau austenitic stainless hlau tsis yog cov khoom zoo tshaj plaws rau lub valve stem, vim tias kom ntseeg tau tias muaj qee lub zog, lub cheeb ntawm lub valve stem yuav nce. Qhov yield point tsis tuaj yeem nce los ntawm kev kho cua sov, tab sis nws tuaj yeem nce los ntawm kev tsim txias.
Peb yog cov khw muag khoom ntawm cov yeeb nkab carbon thiab stainless seamless steel, txais tos txhua qhov kev nug, peb yuav muab thawj zaug!
