Submerged Arc Vuam (SAW) yog dab tsi?

Kev vuam hlau submerged arc (SAW), raws li lub npe qhia, yog ua nyob rau hauv qab ib txheej tiv thaiv lossis daim pam ntawm cov kua nplaum. Vim tias cov kua nplaum ib txwm npog los ntawm qhov tuab ntawm cov kua nplaum, nws tshem tawm txhua qhov hluav taws xob los ntawm cov arches uas raug nthuav tawm thiab tseem xav tau cov ntxaij vab tshaus vuam. Nrog ob hom kev hloov pauv ntawm cov txheej txheem, tsis siv neeg thiab semi-automatic, yog ib qho ntawm cov txheej txheem vuam siv dav dav siv hauv kev lag luam txheej txheem. Wenzhou Tianyu Electronic Co., Ltd., ib qho ntawm cov neeg muag khoom hlau submerged arc vuam hlau hauv Suav teb, piav qhia txog lub hauv paus ntsiab lus thiab kev siv ntawm kev vuam sub-arc. Cia peb saib lawv yog dab tsi:

Txheej Txheem:

Ib yam li MIG vuam, SAW kuj siv cov txheej txheem ntawm kev tsim ib lub arc ntawm qhov sib koom ua ke thiab cov hlau electrode liab qab. Ib txheej nyias ntawm flux thiab slag yog siv los tsim cov roj sib xyaw tiv thaiv thiab ntxiv cov alloys xav tau rau hauv lub pas dej vuam, raws li. Thaum lub vuam txuas ntxiv mus, cov hlau electrode raug tso tawm ntawm tib qhov kev siv thiab cov flux ntau dhau raug nqus tawm los ntawm lub tshuab nqus tsev rau kev rov ua dua tshiab. Sib nrug los ntawm kev tiv thaiv cov hluav taws xob, cov txheej flux kuj tseem muaj txiaj ntsig zoo hauv kev zam kev poob cua sov. Qhov ua tau zoo heev ntawm cov txheej txheem no, kwv yees li 60%, yog vim cov txheej flux no. Tsis tas li ntawd, cov txheej txheem SAW yog dawb kiag li ntawm spattering thiab tsis xav tau cov txheej txheem rho tawm pa taws.

Cov txheej txheem ua haujlwm:

Ib yam li lwm yam txheej txheem vuam, qhov zoo ntawm cov pob qij txha vuam txog qhov tob nkag mus, cov duab thiab cov tshuaj lom neeg ntawm cov hlau vuam uas tso rau hauv feem ntau yog tswj los ntawm cov txheej txheem vuam xws li tam sim no, arc voltage, weld wire feed rate, thiab weld travel speed. Ib qho ntawm cov teeb meem (ntawm chav kawm muaj cov txheej txheem los tawm tsam lawv) yog tias tus welder tsis tuaj yeem saib lub pas dej vuam thiab yog li qhov zoo ntawm lub qhov dej yog nyob ntawm cov txheej txheem ua haujlwm.

Cov txheej txheem tsis:

Raws li tau hais ua ntej lawm, nws tsuas yog nrog cov txheej txheem txheej txheem, thiab tus kws vuam ua kom lub qhov sib koom ua ke zoo meej. Piv txwv li, hauv cov txheej txheem tsis siv neeg, qhov loj ntawm cov hlau thiab cov dej ntws uas siv uas haum rau hom, tuab ntawm cov khoom siv, thiab qhov loj ntawm txoj haujlwm ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov nrawm ntawm kev tso tawm thiab cov duab ntawm cov hlaws dai.

Hlau:

Nyob ntawm qhov xav tau ntawm qhov tso nyiaj thiab qhov ceev ntawm kev mus ncig ua raws li cov xov hlau tuaj yeem xaiv tau

·Ob txoj hlua

· Muaj ntau cov xov hlau

· Cov hlau tubular

· Ntxiv hmoov hlau

· Ib txoj hlua nrog kub ntxiv

· Ib txoj hlua nrog kev ntxiv txias

Kev hloov pauv:

Cov khoom sib xyaw ua ke ntawm cov oxides ntawm ntau yam ntsiab lus xws li manganese, titanium, calcium, magnesium, silicon, txhuas, thiab calcium fluoride yog siv dav ua cov flux hauv SAW. Feem ntau, qhov kev sib xyaw ua ke raug xaiv xws li nws muab cov khoom siv kho tshuab uas xav tau thaum nws sib xyaw nrog cov hlau vuam. Nws kuj tseem yuav tsum tau sau tseg tias cov khoom sib xyaw ntawm cov fluxes no ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm arc voltage thiab cov kev teeb tsa tam sim no. Raws li qhov xav tau vuam, feem ntau ob hom fluxes, bonded thiab fused yog siv rau hauv cov txheej txheem.

Siv:

Txhua txoj kev vuam muaj nws cov ntawv thov, uas feem ntau sib tshooj vim yog qhov ntsuas ntawm kev lag luam thiab qhov xav tau zoo.

Txawm hais tias SAW tuaj yeem siv tau zoo heev rau ob qho tib si pob qij txha (ntev thiab ncig) thiab pob qij txha fillet, nws muaj ob peb qhov kev txwv me me. Vim yog qhov fluidity ntawm lub pas dej weld, slag hauv lub xeev molten thiab ib txheej xoob ntawm flux, pob qij txha butt yeej ib txwm nqa tawm hauv qhov chaw tiaj tus, thiab ntawm qhov tod tes, pob qij txha fillet tau ua tiav hauv txhua qhov chaw - tiaj tus, kab rov tav, thiab ntsug.

Yuav tsum nco ntsoov tias tsuav yog cov txheej txheem thiab kev xaiv cov kev cai rau kev npaj sib koom ua ke tau ua tiav, SAW tuaj yeem ua tiav rau cov khoom siv ntawm txhua qhov tuab.

Nws tuaj yeem siv tau zoo rau cov hlau carbon, cov hlau tsis xeb thiab cov hlau tsis tshua muaj hlau thiab kuj tseem muaj ob peb cov hlau tsis muaj hlau thiab cov ntaub ntawv, yog tias ASME code tau hais tias kev sib xyaw ua ke ntawm cov hlau thiab cov dej ntws tau siv.

SAW pom qhov chaw ruaj khov hauv kev lag luam tshuab hnyav thiab kev lag luam tsim nkoj rau cov khoom siv vuam loj, cov kav dej loj, thiab cov hlab dej ua haujlwm.

Nrog kev siv cov hlau electrode siab heev thiab cov peev xwm ua haujlwm tau yooj yim, SAW yeej ib txwm yog ib qho ntawm cov txheej txheem vuam uas neeg xav tau tshaj plaws hauv kev lag luam tsim khoom.
