Ma electrode a graphite ndi chinthu chachikulu chotenthetsera chomwe chimagwiritsidwa ntchito mu ng'anjo yamagetsi, njira yopangira zitsulo pomwe zidutswa za magalimoto akale kapena zida zamagetsi zimasungunuka kuti apange chitsulo chatsopano.
Zitofu zamagetsi zomangira ndi zotsika mtengo kupanga kuposa zitofu zachikhalidwe zomangira, zomwe zimapanga chitsulo kuchokera ku chitsulo ndipo zimayendetsedwa ndi malasha ophikira. Koma mtengo wopanga chitsulo ndi wokwera chifukwa zimagwiritsa ntchito zidutswa zachitsulo ndipo zimayendetsedwa ndi magetsi.
Ma electrode ndi gawo la chivindikiro cha ng'anjo ndipo amasonkhanitsidwa m'mizere. Kenako magetsi amadutsa m'ma electrode, ndikupanga kutentha kwakukulu komwe kumasungunula chitsulo chotsala. Ma electrode amasiyana kwambiri kukula koma amatha kukhala ndi mainchesi 0.75 (mapazi 2 ndi theka) komanso kutalika kwa mamita 2.8 (mapazi 9). Yaikulu kwambiri imalemera matani oposa awiri.
Zimatenga ma electrode a graphite okwana makilogalamu atatu (6.6 lb) kuti apange tani imodzi yachitsulo.
Nsonga ya elekitirodiyo idzafika madigiri 3,000 Celsius, theka la kutentha kwa pamwamba pa dzuwa. Ma electrode amapangidwa ndi graphite chifukwa graphite yokha ndi yomwe imatha kupirira kutentha kwakukulu kotere.
Kenako ng'anjoyo imapendekeka mbali yake kuti itsanulire chitsulo chosungunukacho m'mabaketi akuluakulu otchedwa ma ladle. Kenako ma ladlewo amanyamula chitsulo chosungunukacho kupita nacho ku fakitale yachitsulo, yomwe imapanga zinthu zatsopano kuchokera ku zidutswa zobwezerezedwanso.
Magetsi ofunikira pa ntchitoyi ndi okwanira kupatsa mphamvu tawuni yokhala ndi anthu 100,000. Kusungunuka kulikonse mu uvuni wamagetsi wamakono nthawi zambiri kumatenga mphindi pafupifupi 90 ndipo kumapanga matani 150 achitsulo, chokwanira magalimoto pafupifupi 125.
Needle coke ndiye chinthu chachikulu chomwe chimagwiritsidwa ntchito mu ma electrode omwe opanga amati angatenge miyezi isanu ndi umodzi kuti apange pogwiritsa ntchito njira monga kuphika ndi kuwotcha kuti asinthe coke kukhala graphite.
Pali singano coke yopangidwa ndi mafuta ndi singano coke yopangidwa ndi malasha, ndipo iliyonse ingagwiritsidwe ntchito kupanga ma electrode a graphite. 'Pet coke' ndi chinthu chochokera mu njira yoyeretsera mafuta, pomwe singano coke yopangidwa ndi malasha imapangidwa kuchokera ku phula la malasha lomwe limawonekera popanga singano.
Pansipa pali opanga ma electrode apamwamba kwambiri padziko lonse lapansi omwe adayikidwa m'gulu la ma electrode a graphite potengera mphamvu yopangira mu 2016:
