Kev Tsim Qauv Graphite Electrodes rau Arc Furnacts yuav tsum muaj feem ntau qhov tseem ceeb: kev ua haujlwm, kav ntev, thiab tus nqi. Txhua qhov tivthaiv -} los ntawm particle loj hauv cov ntaub ntawv raw rau qhov kawg ntawm cov lus xav tau ntawm EAF kev ua haujlwm.

Xaiv ib qho tseem ceeb tsim qauv yog qib electrode. Ultra - high {{2} · m, yog cov qauv rau EAFs tam sim no, raws li qhov ua tau zoo tam sim no txawv thiab tau ua kom nrawm dua qub. High - Power (HP) Electrodes (resistivity 60-7 m) ua cov khoom siv me me (· m) yog phased tawm vim yog lub zog.

Geometry kuj yog lub luag haujlwm tseem ceeb. Tapered Profiles (nqaim ntawm qhov taub) faib cua kub ntau dua, txo cov cua sov thiab txuas lub tswv yim lub neej. Diamool tshaj plaws (txog li 700 hli) qis dua tam sim no ceev, txo qhov kub me. Piv txwv li, 600 hli UHP electrode nyob rau hauv ib 200-tuj EAF txo kev siv hluav taws xob los ntawm 15% piv rau 500 mm hp electrode.

Cov khoom siv huv tsis yog - sib yeem. Impurities zoo li cov leej faj lossis hlau nce resistivity thiab nrawm oxidation. Hwm eaf graphite hluav taws xob siv roj av coke nrog sulfur <0.3% thiab tag nrho impurities <0.1%, kom ua tau zoo sib xws. Post {{6-} Kev tsim kho cov khoom siv, xws li Resin Impride lossis silicon carbide txheej, txuas ntxiv lub neej ntawm lub neej los ntawm 30- kev ua haujlwm.

Kev tsim kho txuas ntxiv mus rau kev txhim kho tsav. Modular cov hluav taws xob (nrog cov ntu hloov pauv) Txo cov khib nyiab los ntawm kev tso cai tsuas yog cov taub hau kom hloov. Tiag -}}}} saib cov ntaub ntawv saib xyuas, ua ke rau hauv cov electrodes, muab cov ntaub ntawv rau ntawm kev saib xyuas kub thiab hnav, ua kom pom kev txij nkawm. Raws li EAFs hloov zuj zus mus rau Smarter, ntau qhov kev ua haujlwm, cov qauv electrode tsim tseem nyob ntawm qhov chaw ua ntej ntawm steelmaking innovation.
