Uas flux siv nyob rau hauv submerged arc vuam?

Submerged Arc Vuam (pom) nyob rau hauv txoj hauj lwm muaj nyob hauv txoj kev lag luam kev lag luam, thiab cov txheej txheem kev siv vuam ua kom zoo thiab ua haujlwm tau zoo ntawm vuam. Yog li, qhov fluxes feem ntau siv nyob rau hauv submerged arc vuam? Peb tshawb nrhiav kom meej.
Cov ntsiab lus fluxes rau submerged arc vuam
Fused fluxes
Feded fluxes yog tsim los ntawm melting sib xyaw ntawm cov khoom nyoos xws li silica, mangium fluoride ntawm txias thiab crushing mus rau hauv cov ntaub ntawv granular. Ib qho piv txwv yog HJ431, uas zoo li xim av mus rau lub teeb daj iav granules granules.
Hom tshuaj lom zem no tau khav theeb hluav taws xob kev ua haujlwm zoo, ua rau nws tswj tau lub arc ruaj khov thaum lub vijtsam vuam. Nws yog dav siv nyob rau hauv lub vuam ntawm cov roj carbon hlau thiab qee qhov qis-} cov hlau almoy. Thaum ua khub nrog xaim nrog H08A thiab H08MA, nws tuaj yeem txhim kho cov khoom siv hluav taws xob ntawm weld hlau los ntawm kev siv hlau. Nws pom dav dav ntawm kev lag luam xws li boiler raug, nkoj nkoj, thiab siab hlwv ntawm cov ntaub.
Sintered fluxes
Sintered fluxes yog tsim los ntawm kev sib xyaw cov hmoov nplej raw thiab tom qab ntawd hauv qab qhov kub hauv qab no lawv cov ntsiab lus hauv qab no (feem ntau ntawm {{0} degree). SJ101 yog ib tug sawv cev fluorine- alkaline sintered flux nrog alkalinity ntawm kwv yees li ntawm 1.8.
Nws ua rau pom kev ua tau zoo desulfurization, ua kom zoo txo ​​cov sulfur thiab phosphorus ntsiab lus nyob rau hauv weld hlau thiab cuam tshuam qhov kev cuam tshuam kub} kub todnness Toughning ntawm Weld. Yog li ntawd, nws yog qhov tsis tseem ceeb nyob rau hauv loj- nplai} kev tsim kho tshuab xws li choj tsim kho thiab} East gas} East roj Pipeline Project. Lwm hom, SJ301, ib qho silicon {{calicium neupium neutral flux, yog haum rau txoj kev lag luam siab yog rau nws cov shag luv luv uas tsis yooj yim ntws.
Agglomerated fluxes
Agglomerated fluxes yog ua los ntawm kev sib xyaw cov hmoov nplej raw nrog cov nplais (xws li so kom qhuav thiab cua sov- kho. Cov lus yaj-3 yog ib hom alkaline agglomerated flux.
Nws muaj qhov siab tam sim no - nqa muaj peev xwm ua tau muaj peev xwm ua tau zoo {{1} Kev kub hnyiab, thiab cov hlab ntsha, thiab boilers. Nyob ntev 6, tsim los kom muaj siab- ceev vuam, tuaj yeem ua tiav weld weld loj thiab siv vuam muag thiab nruab nrab tensile thiab kav dej.
Qhov tseem ceeb rau Flux xaiv
Paus hom
Rau cov roj carbon steel thiab tsawg {{{- cov ntsiab lus hlau nrog cov ntsiab lus muaj txiaj ntsig, ua kom muaj kev lom zem tshwj xeeb zoo li HJ431 yog qhov kev xaiv zoo. Rau qis -} riam siv kom muaj zog thiab tawv, sintered flux hj350 yog qhov tsim nyog dua. Thaum vuam hlau stainless, los tiv thaiv cov khoom poob, fluxes xws li hj260 (flux) thiab sintered flux) feem ntau xaiv.
Weld Sib Koom Tes
Yog tias tus weld sib koom ua ke kom muaj lub zog siab thiab cov qauv zoo, zoo li ntawm SJ101) thiab siab}} almoy steel hlau tuaj yeem ua tau raws li qhov yuav tsum tau ua. Hauv cov xwm txheej nrog corrosion tsis kam, xws li tshuaj chemical thiab cov tub rog sib piv, ua kom muaj kev sib piv ntawm Weld, kom ntseeg tau tias nws cov khoom siv xeb ntawm cov hlau.
Vuam cov txheej txheem tsis
Qee qhov flued fluxes, nrog lawv cov hluav taws xob muaj hluav taws xob muaj zog, yog tsim nyog rau high - ro} ro}} siv vuam siab tam sim no. Agglomerated Flux raaj yaj yaj- 3 tuaj yeem siv nrog cov khoom siv hluav taws xob loj ntawm cov tuab- section materials materials. SININTED Flux SJ501 tuaj yeem txhawb cov high-ceev vuam txog 70m / h lossis ntau dua, ua rau nws xaiv thawj zaug rau kev tsim cov khoom zoo.
Qhov tseem ceeb ntawm Flux hauv kev lag luam ntau lawm
Qhov tseeb xaiv ntawm Flux yog qhov tseem ceeb rau kev lag luam khoom lag luam. Nyob rau hauv kev nyab xeeb -}}} kev lag luam xws li boilers thiab siab vessels thiab ua kom zoo vuam zoo thiab zam kev phom sij kev nyab xeeb thiab zam kev nyab xeeb. Nyob rau hauv cov txheej txheem loj uas zoo li nkoj thiab txuas hniav, nws thiaj li ua rau muaj kev ruaj khov thiab kev pabcuam lub neej. Nyob rau hauv high - kev ua tau zoo ntawm cov liaj ua haujlwm xws li muab cov yeeb nkab muab tau zoo thiab ua kom muaj peev xwm ntau ntxiv.
Cov kws tshaj lij kev lag luam kom muaj kev nkag siab zoo txog cov yam ntxwv ntawm cov yam ntxwv uas tsim nyog rau kev ua tiav ntawm cov khoom lag luam ntawm cov khoom lag luam ntawm cov khoom lag luam.
