Ma electrode a graphite ndiye chinthu chachikulu chotenthetsera chomwe chimagwiritsidwa ntchito mu ng'anjo yamagetsi yamagetsi, njira yopangira zitsulo pomwe zidutswa zamagalimoto akale kapena zida zamagetsi zimasungunuka kuti zipange chitsulo chatsopano.
Kumanga ng'anjo zamagetsi ndi zotsika mtengo kusiyana ndi ng'anjo zachikale, zomwe zimapanga zitsulo kuchokera kuzitsulo zachitsulo ndipo zimawotchedwa ndi malasha. Koma mtengo wopangira zitsulo ndi wokwera chifukwa amagwiritsa ntchito zitsulo zachitsulo komanso zoyendetsedwa ndi magetsi.
Ma electrode ndi gawo la chivindikiro cha ng'anjo ndipo amasonkhanitsidwa kukhala mizati. Magetsi amadutsa mu maelekitirodi, kupanga arc ya kutentha kwakukulu komwe kumasungunula zitsulo zotsalira. Ma elekitirodi amasiyana kwambiri kukula kwake koma amatha kufika mamita 0.75 (mamita 2 ndi theka) m’mimba mwake komanso mpaka mamita 2.8 (mamita 9) m’litali. Chachikulu chimalemera matani opitilira matani awiri.
Zimatengera 3 kg (6.6 lb) ya maelekitirodi a graphite kuti apange tani imodzi yachitsulo.
Nsonga ya electrode idzafika madigiri 3,000 Celsius, theka la kutentha kwa dzuŵa. Ma elekitirodi amapangidwa ndi graphite chifukwa ndi graphite yokha yomwe imatha kupirira kutentha kwambiri.
Kenaka ng’anjoyo amamangirira m’mbali mwake kutsanulira zitsulo zosungunukazo m’zidebe zazikulu zotchedwa ladles. Kenako zitsulozo zimanyamula zitsulo zosungunulazo n’kupita nazo pamalo opangira zitsulo, zomwe zimapanga zinthu zatsopano kuchokera ku zinyalala zomwe zakonzedwanso.
Magetsi ofunikira pa ntchitoyi ndi okwanira kuti apereke mphamvu m’tauni yokhala ndi anthu 100,000. Kusungunuka kulikonse mung'anjo yamakono yamagetsi kumatenga pafupifupi mphindi 90 ndikupanga matani 150 achitsulo, okwanira pafupifupi magalimoto 125.
Needle coke ndiye chinthu chachikulu chomwe chimagwiritsidwa ntchito mu maelekitirodi omwe opanga amati zitha kutenga miyezi isanu ndi umodzi kuti apange ndi njira zophatikizira kuphika ndi kuphikanso kuti asinthe coke kukhala graphite.
Pali singano yopangidwa ndi mafuta a petroleum ndi coke ya singano yokhala ndi malasha, ndipo mwina ingagwiritsidwe ntchito kupanga ma electrode a graphite. 'Pet coke' imapangidwa kuchokera ku njira yoyenga mafuta, pomwe coke ya singano yopangidwa ndi malasha imapangidwa kuchokera ku phula la malasha lomwe limawonekera popanga coke.
Pansipa pali omwe amapanga ma elekitirodi a graphite padziko lonse lapansi malinga ndi kuchuluka kwa kupanga mu 2016:
