Duab: Cov khoom ci ci yog raug rau kev kho kub siab (saum toj 3000 degree) nyob rau hauv ib lub cub hluav taws xob rau rov ua rau high-purity graphite.
Ntaub: Cov electrodes yog precision-machined (tig, xov, thiab lwm yam) kom ntseeg tau qhov tseeb.
2,Kev Tawm Tsam Tawm Kev Kho Mob Oxidation
Txheej Xaiv: Cov txheej txheej muaj xws li aluminium raws li txhuas-based, los yog sib xyaw ua ke (piv txwv li, al-Si-si, zro₂).
Txheej Txheej Txheem:
Cov Qauv Immersion: Electrodes yog dipped rau hauv coating slurry thiab tom qab ntawd kho thaum kub siab.
Txau txoj kev: Plasma lossis nplaim taws yog siv rau qhov siab-melting-point ceramic txheej.
Tshuaj Vauv Vacor Deposition (CVD): Ua kom cov txheej txheem siab txheej txheej tab sis kim dua.
Kev Kho Mob Tom Qab: Kev kub siab sintering (500-800 DEGREE) Txhim Kho Cov Ntawv Adadesion.
Ii. Khoom Taw Qhia

III. Cov Ntawv Thov
Hlau Metallurgy
Fais arc rauve (EAF) steelmaking: Thawj daim ntawv thov, tshwj xeeb tshaj yog oxidative rauv taws ua kom muaj mob.
Looj rauv taws (lf) kho kom zoo: Txo cov pob hluav taws xob hauv tsev hauv theem nrab.
Tsis-ferrous hlau smelting
Ferroalloys (SI / MN / CR): Tsis kam muaj siab-kub corrosion hauv submerged arc rauv.
Muaj Silicon / Daj Phosphorus: Ntev ntev cov hluav taws xob rau cov kev cuam tshuam ntau.
Lwm qhov kev lag luam kub-kub
Silicon Carbide / Corundum Ntau Lawm: Yuav tsum muaj lub sijhawm ntev ua kom sov.
Calcium carbide / graphitization rauv: Txo cov peev txheej electrode.
Cov Khoom Siv Hluav Taws Xob Tshiab
Graphitizitization of Lithium Roj Teeb Anodes: Coated electrodes txo cov ntsiab lus impurity.
Cov Nta Tseem Ceeb:
Los tiv thaiv oxidation txheej
Cov electrodes yog coated nrog cov txheej tiv thaiv (piv txwv, cov khoom siv sib cav, lossis lwm cov khoom siv regramation) kom txo qis oxidation thaum muaj mob kub (txog 600-700).
Cov txheej ua raws li txoj kev thaiv ua ib qho kev cuam tshuam, txo qhov kev tawm tsam ntawm graphite thiab oxygen / co₂ hauv qhov chaw cua sov.
Txhim Kho Durability
Txo cov electrode kev noj los ntawm 20-50% piv rau cov ntaub ntawv graphite graphite.
Txo cov nqi ntawm cov oxidation thiab dav yaig.
Txhim Kho Thermal Stability
Saib xyuas cov qauv txheej txheem hauv qab huab cua sov, txo kev tawg thiab spalling.
Tus Nqi Muaj Zog
Siv lub zog ntev txhais tau tias tsawg electrode hloov chaw, txo qis cov nqi ua haujlwm.
Cov txiaj ntsig:
Txo cov oxidation poob:Tsawg electrode burn-tawm thaum steelmaking lossis lwm cov txheej txheem kub.
Txuag txuag:Txo cov kev noj hluav taws xob ua rau txo qis kev siv fais fab.
