Dab tsi yog graphite electrodes, thiab lub luag hauj lwm dab tsi koob coke ua si hauv lawv ntau lawm?
🔹 Qhov xwm txheej graphite yog dab tsi?
Graphite electrodes yog siab - Kev ua kom haum, siab}------ {}}- {1} Siv hluav taws xob graphite, feem ntau siv los ua hluav taws xob hauv kev siv hluav taws xob uas tsim cua sov. Lawv feem ntau siv nyob rau hauv cov hluav taws kub arc (EAFS) rau melting seem steel thiab kuj tseem nrhiav tau hauv ferrroalloy ntau lawm, thiab electrolysis.
Thaum cov hluav taws xob siab dhau los ntawm graphite electrode, nws tsim muaj hluav taws xob arc nrog cov hlau hlau), nyiam cov kev hloov pauv ntawm 3000-4000 Degree- txaus kom yaj cov hlau. Graphite hluav taws xob yuav tsum yog li hluav taws xob daws, kub ruaj khov, kho tshuab muaj zog, thiab tiv taus cua sov thiab tshuaj corrosion.
Lawv tuaj sib txawvCov menyuam kawm qibRaws li kev ua tau zoo:
•Lub zog tsis tu ncua (RP)
•Muaj Zog Muaj Zog (HP)
•Ultra - High High High High High (UHP)
(UHP cov electrodes yog qhov kev coj ua tshaj plaws thiab muaj txiaj ntsig, siv hauv kev siab niaj hnub {}}} tso tawm EAFs.)
🔹 Qhov Coke koob hmoov npaum li cas?
Koob coke yog thawj cov khoom siv siv los tsim graphite electrodes. Nws yog cov ntshiab heev, siab-} Cov roj carbon monoxide} Cov roj carrobery lossis cov ntaub ntawv txuas. Cov qauv no ua rau muaj lub zog, kev taw qhia, thiab kev ua tau zoo ntawm cov khoom lag luam graphite kawg.
Cov yam ntxwv tseem ceeb ntawm koob Coke:
•High Carbon Content (>95–98%)
•Tsawg sulfur, nitrogen, thiab hmoov tshauv(Rau siab -} Cov Hluav Taws Xob Zoo)
•Koob - zoo li crystal qauv(Txhim kho cov hluav taws xob hluav taws xob lub zog thiab hluav taws xob)
•Thermal ruaj khov(Tuaj yeem tiv taus huab ua kom sov)
Ines Yuav tsum siv cov Coke hluav taws xob koob
1.Sib tov nrog binder (thee tar suab):
Koob Ceke hais tau sib xyaw nrog cov ntaub thee, uas ua raws li phau ntawv los tuav tuav cov lus ua ke hauv thawj "ntsuab" xeev.
2.Moulding:
Cov sib tov yog moulded rau hauv cylindrical lossis cov duab kev cai nyob rau hauv cov kev kub siab.
3.Ci:
Daim duab puab electrode yog ci hauv qhov cub ntawm 800-1200℃rau carbonize lub suab thiab daim ntawv ua cov qauv carbon.
4.Graphitizitizitization:
Thaum kawg, lub ci electrode yog raug rau huab cua sov hnyav (2500-3000 degree) hauv cov amorphous carbon ua kom tiav cov ntaub ntawv crystalline graphite. Cov kauj ruam no tseem txhim kho hluav taws xob conduction, thermal conductivity, thiab lub zog kho tshuab muaj zog.
Vim li cas koob coke teeb meem
•Zoo ntawm koob coke ncaj qha txiav txim siab qhov ua tau zooNtawm kawg graphite electrode.
•Siab -} Cov Khaub Ncaws Coke(Tsis muaj impurities, qauv zoo) ua rauZoo dua conduction, txo qis noj, thiab ntev dua electrode lub neej.
•Hwm Mow Coke yog qhov tseem ceeb rau UHP electrodesSiv nyob rau hauv kev tshaj lij stathmaking thiab lub zog - zoo txheej txheem.
Graphite hluav taws xob yog qhov tseem ceeb tiv thaiv hluav taws xob uas tsim hluav taws xob ntau rau cov hlau kub siab rau cov hlau melting, tshwj xeeb hauv EAF steelmaking. Lawv yog tsim los ntawm koob coke - qhov siab muaj roj carbon monoxe}}} Cov pa roj carbon monoxial, thiab cov khoom siv hluav taws xob, thiab cov kws kho mob xav tau rau cov ntawv thov xav tau.
Ua ke, graphite electrodes thiab koob COE tsim lub pob kws ntawm cov niaj hnub me me, lub zog cia, thiab siab} kub kev tsim.
•Graphite electrodes=Cov Cuab Yeej Siv Rau Siab-} Cov txheej txheem kub
•Koob coke=cov nyiaj tau los ntawm cov khoom siv uas ua rau muaj kev ua tau zoo hluav taws xob
