Electrodes-ka graphite waa walxaha ugu muhiimsan ee kuleyliyaha loo isticmaalo foornada arc koronto ah, habka birta samaynta halkaasoo qashinka baabuurtii hore ama qalabka lagu dhalaaliyo si loo soo saaro bir cusub.
Foornooyinka korontada ku shaqeeya ayaa ka raqiisan in la dhiso marka loo eego foornooyinka qaraxyada ee dhaqameed, kuwaas oo ka sameysan birta birta oo lagu shido korantada.Laakiin qiimaha birta samaynta ayaa ka sarreeya maadaama ay isticmaalaan qashinka birta ah oo ay ku shaqeeyaan koronto.
Electrodes-yadu waa qayb ka mid ah daboolka foornada waxaana la isugu geeyaa tiirar.Korontadu waxay markaa sii dhex martaa electrodes-ka, taasoo samaynaysa xajin kulayl daran oo dhalaalinta birta qashinka ah.Electrodes aad bay u kala duwan yihiin cabbirkooda laakiin waxay noqon karaan ilaa 0.75 mitir (2 cagood iyo badh) dhexroor iyo ilaa 2.8 mitir (9 cagood) dherer ah.Midka ugu weyn ayaa miisaankiisu ka badan yahay laba metrik ton.
Waxay qaadataa ilaa 3 kg (6.6 lb) ee electrodes graphite si ay u soo saarto hal tan oo bir ah.
Cidhifka korantada ayaa gaari doonta 3,000 darajo Celsius, kala bar heerkulka qorraxda ee korkeeda.Electrodes waxay ka samaysan yihiin graphite sababtoo ah graphite kaliya ayaa u adkeysan kara kulaylka daran.
Foornada ayaa markaa dhinaceeda loo dhejiyaa si loogu shubo birta dhalaalaysa baaldiyo waaweyn oo loo yaqaan 'ladles'.Saqafka ayaa markaa birta dhalaalaysa u qaada tuubada birta, taasoo ka samaysa alaab cusub qashinka dib loo warshadeeyey.
Korontada loo baahan yahay habkan ayaa ku filan in ay koronto magaalo ay ku nool yihiin 100,000 oo qof.Mid kasta oo dhalaalaysa foornada koronto ee casriga ah waxay caadi ahaan qaadataa ilaa 90 daqiiqo waxayna samaysaa 150 tan oo bir ah, oo ku filan ilaa 125 baabuur.
Coke irbadu waa alaabta ugu muhiimsan ee loo isticmaalo electrodes-ka ay soosaarayaashu sheegaan inay qaadan karaan ilaa lix bilood si ay u sameeyaan habab ay ku jiraan dubista iyo dib u dubista si loogu beddelo kookaha garaafyada.
Waxa jira coke irbad ku salaysan batroolka iyo coke irbad dhuxul ku salaysan, midna waxa loo isticmaali karaa in lagu soo saaro electrodes graphite.'Pet Coke' waa wax ka soo baxay habka sifaynta saliidda, halka coke-ku-saleysan dhuxusha laga sameeyay daamurka dhuxusha oo soo muuqda xilliga soosaarka kookaha.
Hoos waxaa ah soosaarayaasha ugu sarreeya adduunka ee electrodes-ka graphite ee lagu qiimeeyay awoodda wax soo saarka 2016:
