Cov hlau flux cored yog tsim los rau kev vuam cov hlau tsis muaj steel uas muaj cov pa roj carbon tsawg uas muaj 18-20% chromium thiab 8-12% nickel. Cov khoom sib xyaw tshwj xeeb no muab kev vuam zoo heev, ua kom cov neeg vuam tuaj yeem ua tiav cov pob qij txha muaj zog, txhim khu kev qha nrog kev siv zog tsawg kawg nkaus. Qhov muaj ferrite hauv cov hlau vuam yog qhov tseem ceeb hauv kev txo qhov kev cuam tshuam rau kev tawg. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov uas qhov kev ua tiav ntawm cov qauv tseem ceeb, vim nws txo qhov kev pheej hmoo ntawm kev ua tsis tiav vim muaj kev ntxhov siab lossis cov yam ntxwv ib puag ncig.
Ib qho ntawm cov txiaj ntsig tseem ceeb tshaj plaws ntawm kev siv Qib A 5.22 E308L T1-1 flux-cored hlau yog nws cov khoom siv kho tshuab zoo dua hauv lub xeev welded. Qhov no txhais tau tias cov welds tsim los ntawm kev siv cov hlau no muaj lub zog zoo heev thiab toughness, ua rau lawv haum rau ntau yam kev siv. Txawm hais tias koj ua haujlwm ntawm kev tsim kho, kev tsim khoom lossis kev kho, cov hlau vuam no ua kom koj cov welds tuaj yeem tiv taus qhov nyuaj ntawm lawv cov kev siv. Tsis tas li ntawd, cov hlau cov pa roj carbon qis dua ua rau nws tsis kam rau intergranular corrosion, ua rau nws zoo tagnrho rau cov chaw uas xeb yog qhov txhawj xeeb.
Ntxiv rau cov khoom siv kho tshuab, qhov yooj yim ntawm kev siv cov hlau flux-cored tsis tuaj yeem tsis quav ntsej. Cov khoom tiv thaiv tus kheej ntawm cov hlau flux-cored muab rau nws ntau yam kev hloov pauv hauv ntau qhov chaw vuam thiab tej yam kev mob. Qhov no txhais tau tias cov neeg vuam tuaj yeem ua tiav cov txiaj ntsig zoo txawm tias nyob rau hauv ib puag ncig nyuaj, xws li sab nraum zoov lossis hauv cov xwm txheej cua hlob. Ua haujlwm tau zoo yam tsis tas yuav siv roj tiv thaiv sab nraud ua rau cov hlau flux-cored yog thawj qhov kev xaiv rau ntau tus kws tshaj lij.
Siv cov hlau flux-cored, tshwj xeeb tshaj yog Qib A 5.22 E308L T1-1 stainless hlau hlau, muaj ntau yam txiaj ntsig rau cov neeg vuam uas tab tom nrhiav cov txiaj ntsig zoo. Nws qhov kev vuam zoo heev, cov khoom siv kho tshuab zoo dua thiab kev tiv thaiv corrosion zoo dua ua rau nws yog ib qho khoom muaj nqis rau kev lag luam vuam. Los ntawm kev xaiv cov hlau vuam siab heev no, cov kws tshaj lij tuaj yeem ua kom lawv cov haujlwm tsis yog tsuas yog ua tau raws li cov qauv kev lag luam xwb, ua rau muaj kev vuam ruaj khov, txhim khu kev qha uas sawv ntawm qhov kev sim ntawm lub sijhawm. Txawm hais tias koj yog tus kws vuam uas muaj kev paub dhau los lossis nyuam qhuav pib, kev nqis peev rau cov hlau flux-cored zoo yog qhov kev txiav txim siab uas yuav them rov qab rau lub sijhawm ntev.
