Electrodes-ka graphite waa walxaha ugu muhiimsan ee kuleyliyaha loo isticmaalo foornada korantada, habka birta samaynta halkaas oo qashinka baabuurta 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 ah waxaana lagu shido dhuxusha. 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 waxayna isku urursan yihiin 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 electrode-ku wuxuu gaari doonaa 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 daayaa si birta dhalaalaysa loogu shubo baaldiyo waaweyn oo loo yaqaanno ladles. Kabadhku waxa ay birta dhalaalaysa u qaadaan kasarka birta, taas oo ka samaysa alaab cusub qashinka dib loo warshadeeyay.
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 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 sheegeen inay qaadan karaan ilaa lix bilood si ay u sameeyaan habab ay ku jiraan dubista iyo dib u dubista si loogu beddelo kookaha garaafyada.
Waxaa jira coke irbad ku salaysan batroolka iyo coke irbad dhuxul ku salaysan, midna waxaa loo isticmaali karaa in lagu soo saaro electrodes graphite. 'Pet Coke' waa wax ka soo baxay habka sifaynta saliidda, halka coke-ku-salaysan dhuxusha laga sameeyay daamurka dhuxusha oo soo muuqda inta lagu jiro soosaarka kookaha.
Hoos waxaa ku yaal soosaarayaasha ugu sarreeya adduunka ee electrodes graphite oo lagu qiimeeyay awoodda wax soo saarka 2016:
