Kev noj cov graphite electrode nyob rau hauv hluav taws xob rauv steelmaking feem ntau muaj feem xyuam rau qhov zoo ntawm electrode nws tus kheej thiab cov xwm txheej ntawm steelmaking rauv (xws li tshiab los yog qub rauv, mechanical tsis ua hauj lwm, nruam ntau lawm, thiab lwm yam) yog ze ze rau steelmaking ua hauj lwm (xws li. steel qib, oxygen tshuab lub sij hawm, rauv nqi, thiab lwm yam).Ntawm no, tsuas yog kev noj ntawm graphite electrode nws tus kheej tau tham, thiab nws cov txheej txheem noj yog raws li hauv qab no:
1.End noj graphite electrode
Nws suav nrog sublimation ntawm graphite cov khoom tshwm sim los ntawm arc nyob rau hauv qhov kub thiab txias ntawm biochemical cov tshuaj tiv thaiv ntawm graphite electrode kawg, molten steel thiab slag.Qhov kub kub sublimation tus nqi ntawm lub electrode kawg feem ntau yog nyob ntawm qhov tam sim no ceev dhau los ntawm graphite electrode, Secondly, nws muaj feem xyuam rau txoj kab uas hla ntawm oxidized sab ntawm electrode.Tsis tas li ntawd, qhov kawg noj kuj tseem cuam tshuam txog seb cov electrode muab tso rau hauv cov hlau molten kom nce cov pa roj carbon.
2.Side oxidation ntawm graphite electrode
Cov tshuaj muaj pes tsawg leeg ntawm cov electrode yog carbon, Oxidation cov tshuaj tiv thaiv yuav tshwm sim thaum carbon tov nrog huab cua, dej vapor thiab carbon dioxide nyob rau hauv tej yam kev mob.thiab tus nqi ntawm oxidation ntawm sab ntawm graphite electrode muaj feem xyuam rau chav tsev oxidation tus nqi thiab raug cheeb tsam.Feem ntau, kev noj ntawm graphite electrode sab nyiaj rau ib ncig ntawm 50% ntawm tag nrho cov kev siv ntawm cov electrode.
Nyob rau hauv xyoo tas los no, txhawm rau txhim kho cov smelting ceev ntawm hluav taws xob arc rauv, qhov zaus ntawm oxygen tshuab ua haujlwm tau nce, ua rau muaj zog oxidation poob ntawm electrode.Nyob rau hauv cov txheej txheem ntawm steel ua, lub redness ntawm lub cev electrode thiab lub taper ntawm lub qis kawg yog feem ntau pom, uas yog ib tug intuitive txoj kev los ntsuas oxidation tsis kam ntawm electrode.
3.Tug poob
Thaum cov khoom siv hluav taws xob tsis tu ncua ntawm kev sib txuas ntawm cov hluav taws xob sab sauv thiab sab qis, ib feem me me ntawm electrode los yog lub txiv mis (residue) Kev sib cais tshwm sim vim yog oxidation thinning ntawm lub cev los yog nkag mus ntawm cov kab nrib pleb.Qhov loj ntawm qhov seem kawg poob yog cuam tshuam nrog cov duab ntawm lub txiv mis, hom buckle, cov qauv sab hauv ntawm electrode, kev vibration thiab cuam tshuam ntawm cov kab hluav taws xob.
4.Ntoo tev thiab thaiv kev poob
Nyob rau hauv cov txheej txheem smelting, nws yog tshwm sim los ntawm ceev ceev txias thiab cua sov, thiab tsis zoo thermal vibration kuj ntawm lub electrode nws tus kheej.
5.Electrode tawg
Nrog rau qhov tawg ntawm electrode lub cev thiab lub txiv mis, Electrode tawg yog cuam tshuam rau qhov zoo ntawm graphite electrode thiab txiv mis, Kev sib koom ua ke thiab kev ua haujlwm steel.Cov laj thawj feem ntau yog qhov tseem ceeb ntawm kev tsis sib haum xeeb ntawm steel mills thiab graphite electrode manufacturers.
