Graphite electrodes ndicho chinhu chikuru chekupisa chinoshandiswa muchoto chemagetsi arc, nzira yekugadzira simbi apo zvimedu zvemotokari dzekare kana midziyo inonyungudutswa kugadzira simbi itsva.
Mavhiri emagetsi arc akachipa kuvaka pane echinyakare kuputika mavira, ayo anogadzira simbi kubva kusimbi uye anokwidziridzwa 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 inonyungudutsa simbi yakarashwa.Maelectrodes anosiyana-siyana muhukuru asi anogona kusvika pamamita 0.75 (mafiti maviri nehafu) muhupamhi uye akareba 2.8 metres (9 tsoka).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 degrees Celsius, 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 zvinhu zvitsva kubva pazviraswa 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 mbishi huru inoshandiswa mumaelectrode ayo vanogadzira vanoti inogona kutora kusvika mwedzi mitanhatu kugadzira nemaitiro anosanganisira kubheka nekubika zvakare kushandura coke kuita graphite.
Kune petroleum-based tsono coke uye marasha-based tsono coke, uye chero inogona kushandiswa kugadzira graphite electrodes.'Pet coke' ndeye-chigadzirwa chekunatsa oiri, nepo marasha-based tsono coke inogadzirwa kubva marasha tar inooneka panguva yekugadzira coke.
Pazasi pane vagadziri vepamusoro vepasirese magraphite electrode akaverengerwa nehuwandu hwekugadzira muna 2016:
