I-electrode yegraphite yeyona nto iphambili yokufudumeza esetyenziswa kwisithando sombane se-arc, inkqubo yokwenza intsimbi apho inkunkuma ephuma kwiimoto ezindala okanye izixhobo zombane zinyibilika ukuvelisa intsimbi entsha.
Iziko zombane ze-arc zixabiso eliphantsi ukwakha kuneziko zokuqhumisa zesintu, ezenza intsimbi ngentsimbi ekrwada kwaye zibaswa ngamalahle okucokisa.Kodwa iindleko zokwenza intsimbi ziphezulu njengoko zisebenzisa intsimbi yentsimbi kwaye ziqhutywa ngumbane.
I-electrodes iyingxenye yesivalo sesithando somlilo kwaye ihlanganiswe kwiikholomu.Umbane ke udlula kwii-electrode, wenze i-arc yobushushu obugqithisileyo obunyibilikisa intsimbi endala.Ii-Electrodes ziyohluka ngokubanzi ngobukhulu kodwa zinokufikelela kwi-0.75 yeemitha (iinyawo ezi-2 kunye nesiqingatha) ububanzi kunye ne-2.8 yeemitha (9 iinyawo) ubude.Olona bunzima bungaphezulu kweetoni ezimbini zeemetric.
Kuthatha ukuya kuthi ga kwi-3 kg (6.6 lb) ye-electrode yegraphite ukuvelisa itoni enye yentsimbi.
Incam ye-electrode iya kufikelela kuma-3 000 ngokukaCelsius, isiqingatha sobushushu bomhlaba welanga.Iielectrode zenziwe ngegraphite kuba yigraphite kuphela enokumelana nobushushu obungako.
Eli ziko liya kuthi xhaxhe kwicala lalo ukuze ligalele intsimbi etyhidiweyo kwiiemele ezinkulu ezibizwa ngokuba ziileyile.Iileyile ke ngoko zithwala intsimbi etyhidiweyo ziyise kwindawo yokusila yentsimbi, eyenza imveliso emitsha ngenkunkuma esetyenzisiweyo.
Umbane ofunekayo kule nkqubo wanele ukunika amandla idolophu enabemi be-100,000.Nganye inyibilika kwiziko langoku lombane le-arc ngokuqhelekileyo ithatha malunga nemizuzu engama-90 kwaye yenza iitoni ezili-150 zentsimbi, ezanele iimoto ezimalunga ne-125.
Inaliti ye-coke yeyona nto isetyenziswayo kwi-electrode abathi abavelisi inokuthatha ukuya kwiinyanga ezintandathu ukwenza ngeenkqubo ezibandakanya ukubhaka kunye nokubhaka kwakhona ukuguqula i-coke ibe yigraphite.
Kukho inaliti esekwe kwipetroleum kunye necoke yenaliti esekwe emalahleni, kwaye mhlawumbi ingasetyenziselwa ukuvelisa iielectrode zegraphite.'I-Pet coke' yimveliso ephuma kwinkqubo yokusulungekiswa kwe-oyile, ngeli lixa i-coke yenaliti esekwe emalahleni yenziwe ngetha yamalahle ebonakala ngexesha lokwenziwa kwe-coke.
Apha ngezantsi ngabavelisi abaphezulu behlabathi bee-electrode zegraphite ezibekwe ngokomthamo wemveliso ngo-2016:
