Graphite electrodes ndiyo inonyanya kupisa chinhu chinoshandiswa muchoto chemagetsi arc, nzira yekugadzira simbi apo zvimedu zvemotokari dzekare kana midziyo inonyungudutswa kugadzira simbi itsva.
Masimbi emagetsi arc akachipa kuvaka pane echinyakare kuputika mavira, ayo anogadzira simbi kubva kusimbi ore uye anofambiswa necoking marasha. Asi mutengo wekugadzira simbi wakakwirisa sezvo vachishandisa zvisaririra zvesimbi uye zvinofambiswa nemagetsi.
Ma electrode chikamu chechivharo chechoto uye anounganidzwa kuita makoramu. Magetsi anobva apfuura nemumaelectrodes, ogadzira arc yekupisa kwakanyanya kunonyungudutsa simbi yakarashwa. Maelectrodes anosiyana-siyana muhukuru asi anogona kusvika 0.75 metres (mafiti maviri nehafu) muhupamhi uye akareba 2.8 metres (9 tsoka) kureba. Iyo huru inorema inodarika matani maviri emametric.
Zvinotora kusvika 3 kg (6.6 lb) yemagraphite electrodes kugadzira toni imwe yesimbi.
Musoro we electrode uchasvika 3 000 madhigirii, hafu yetembiricha yepasi pezuva. Maelectrodes anogadzirwa negraphite nekuti graphite chete inokwanisa kutsungirira kupisa kwakanyanya kudaro.
Choto chacho chinobva chaiswa padivi pacho kuti chidire simbi yakanyungudutswa mumabhaketi mahombe anonzi ladles. Maladhi acho anobva atakura simbi yakanyungudutswa ichienda nayo kuchigayo chesimbi, iyo inogadzira zvigadzirwa zvitsva kubva pazvimedu zvinenge zvashandiswa patsva.
Magetsi anodiwa pakuita uku anokwana kusimbaradza guta rine vagari ve100,000. Imwe neimwe inonyungudika muchoto chemazuva ano chemagetsi arc kazhinji inotora maminitsi makumi mapfumbamwe uye inogadzira matani zana nemakumi mashanu esimbi, anokwana mota zana nemakumi maviri neshanu.
Tsono coke ndiyo huru mbishi inoshandiswa mumaelectrode ayo vanogadzira vanoti inogona kutora kusvika mwedzi mitanhatu kugadzira nemaitiro anosanganisira kubheka uye kubika zvakare kushandura coke kuita graphite.
Kune petroleum-based tsono coke uye marasha-based tsono coke, uye inogona kushandiswa kugadzira graphite electrodes. 'Pet coke' ndeye-chigadzirwa chekugadzirisa oiri, nepo marasha-akavakirwa tsono coke inogadzirwa kubva kumarasha tara inoonekwa panguva yekugadzira coke.
Pazasi pane vagadziri vepamusoro vepasirese magraphite electrode akaverengerwa nehuwandu hwekugadzira muna 2016:
