Phau Ntawv Qhia Txog Qhov Kawg Rau Cov Hlau Mos Flux Cored

Flux cored hlauyog ib qho kev daws teeb meem uas siv tau ntau yam thiab ua tau zoo rau kev vuam cov hlau uas muaj cov pa roj carbon tsawg 18-20% Cr/8-12% Ni. Hom hlau no yog tsim los muab kev vuam zoo heev thiab cov khoom siv kho tshuab zoo heev nyob rau hauv cov xwm txheej vuam. Qhov muaj ferrite nyob rau hauv cov hlau vuam txo qhov kev cuam tshuam rau kev tawg, ua rau nws zoo tagnrho rau ntau yam kev siv vuam. Tsis tas li ntawd, cov pa roj carbon qis dua pab txhim kho kev tiv thaiv rau kev xeb intergranular, ua rau nws yog qhov kev xaiv txhim khu kev qha rau cov haujlwm uas xav tau cov vuam zoo.

Thaum vuam cov hlau tsis hnyav, kev xaiv cov hlau flux-cored yog qhov tseem ceeb heev. Cov khoom sib xyaw tshwj xeeb ntawm cov hlau vuam no ua kom cov hlau vuam tsis yooj yim tawg, uas yog qhov teeb meem feem ntau thaum ua haujlwm nrog cov hlau tsis hnyav. Qhov no ua rau nws zoo tagnrho rau cov ntawv thov uas qhov kev vuam ruaj khov yog qhov tseem ceeb, xws li cov qauv lossis cov chaw ua haujlwm hauv kev lag luam.

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv cov hlau flux-cored rau kev vuam hlau tsis hnyav yog nws qhov kev ua haujlwm vuam zoo heev. Cov hlau no yog tsim los tsim cov vuam nrog cov khoom siv kho tshuab zoo heev hauv qab cov xwm txheej vuam, muab cov khoom sib txuas ruaj khov thiab txhim khu kev qha. Qhov no yog qhov tseem ceeb los xyuas kom meej tias cov khoom vuam tau ntev thiab ruaj khov, ua rau nws yog thawj qhov kev xaiv rau ntau yam haujlwm vuam.

Ntxiv rau qhov muaj cov khoom siv vuam zoo heev, cov hlau tsis muaj zog flux-cored kuj tseem muaj kev tiv thaiv zoo dua rau kev xeb intergranular vim nws cov ntsiab lus carbon qis dua. Qhov no tseem ceeb heev rau cov ntawv thov uas cov khoom vuam raug rau qhov chaw ib puag ncig hnyav lossis cov tshuaj corrosive. Cov ntsiab lus carbon qis dua pab tswj kev ncaj ncees ntawm qhov vuam, ua kom ntseeg tau tias kev ua haujlwm ntev thiab kev ntseeg siab.

Hauv kev xaus lus, cov hlau flux cored yog ib qho kev daws teeb meem zoo rau kev vuam cov hlau uas muaj cov pa roj carbon tsawg 18-20% Cr / 8-12% Ni. Nws cov khoom sib xyaw thiab cov yam ntxwv tshwj xeeb ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau kev vuam zoo heev, cov khoom siv kho tshuab thiab kev tiv thaiv corrosion. Los ntawm kev xaiv cov hlau flux-cored zoo, cov neeg vuam tuaj yeem ua tiav cov vuam zoo uas ua tau raws li cov qauv siab tshaj plaws ntawm kev ua tau zoo thiab kev ruaj khov.
