Mtengo wa Graphite Electrode - Dalirani kufunikira kwa msika ndi zinthu zosaphika

1. Kufunika Kwambiri kwa Zitsulo Zapamwamba

Ichi ndi chimodzi mwazinthu zazikulu zomwe zikulimbikitsa kukula kwa msika wa ma electrode a graphite. Kukula mwachangu kwa mafakitale achitsulo monga zomangamanga, magalimoto, zomangamanga, ndege ndi chitetezo cha dziko kwapangitsa kuti kufunikira ndi kupanga zitsulo kuchuluke.

2. Ng'anjo yamagetsi ya Arc ndiyo njira yomwe ikudziwika kwambiri masiku ano

Chifukwa cha kukhudzidwa ndi kuteteza chilengedwe komanso kusinthasintha kwakukulu kwa kupanga, njira yopangira zitsulo m'maiko osatukuka ikusintha kuchoka pa ng'anjo yophulika ndi ng'anjo ya ladle kupita ku ng'anjo yamagetsi ya arc (EAF). Ma electrode a graphite ndiye gwero lalikulu la mphamvu yogwiritsira ntchito chitsulo chamagetsi, ndipo ma electrode okwana 70% a graphite amagwiritsidwa ntchito popanga chitsulo chamagetsi cha arc. Kukula mwachangu kwa ng'anjo yamagetsi kumakakamiza mphamvu yopangira ma electrode a graphite kuti awonjezereke.

3. Ma Electrode a Graphite ndi Ogwiritsidwa Ntchito

Nthawi yogwiritsira ntchito ma electrode a graphite nthawi zambiri imakhala pafupifupi milungu iwiri. Komabe, nthawi yopangira ma electrode a graphite nthawi zambiri imakhala miyezi 4-5. Pakugwiritsa ntchito kumeneku, mphamvu yopangira ma electrode a graphite ikuyembekezeka kuchepa chifukwa cha mfundo za dziko komanso nyengo yotentha.

4. Singano ya Coke ya High-grade ikupezeka

Needle coke ndi chinthu chofunikira kwambiri popanga ma electrode a graphite. Ndi calcined petroleum coke (CPC) yomwe imawerengera pafupifupi 70% ya ndalama zomwe zimagwiritsidwa ntchito popanga ma electrode a graphite. Kukwera kwa mitengo komwe kumachitika chifukwa cha kuchuluka kochepa kwa ma electrode a needle coke ndi chifukwa chachikulu chomwe chikukwera mwachindunji mtengo wa ma electrode a graphite. Pakadali pano, needle coke imagwiritsidwanso ntchito popanga zipangizo za electrode zamabatire a lithiamu ndi mafakitale a ndege. Kusintha kumeneku kwa kupezeka ndi kufunikira kumapangitsa kuti mtengo wa electrode ya graphite ukhale wosapeweka.

5. Nkhondo Zamalonda Pakati pa Zachuma Zazikulu Padziko Lonse

Izi zapangitsa kuti chuma cha China chichepe kwambiri, ndipo zapangitsa kuti mayiko ena awonjezere mphamvu zopanga zinthu. Kumbali ina, zachititsanso kuti kuchuluka kwa ma electrode a graphite omwe amatumizidwa kunja ku China kuchuluke. Kuphatikiza apo, United States yakweza misonkho pa zinthu zomwe zimatumizidwa kunja ku China, zomwe zachepetsa kwambiri phindu la ma electrode a graphite aku China pamitengo.
