Inkqubo epheleleyo yokuvelisa i-graphitized petroleum coke ibandakanya amanqanaba aliqela, kuquka ukunyanga izinto eziluhlaza ngaphambi kokuba zisetyenziswe, ukutyumza, ukutyumza nokuhlola, ukuxuba nokuxova, ukubumba, ukubhaka, unyango lwe-graphitization, kunye nokucubungula kakuhle kunye nokupakishwa. Nantsi intshayelelo eneenkcukacha:
Ukuhlolwa kwezixhobo eziluhlaza kunye nonyango lwangaphambi kwexesha: Izinto ezisemgangathweni ophezulu ze-petroleum coke carbon ziyakhethwa kwaye zihlolwe kwaye zityunyuzwe ukuze zincitshiswe zibe bukhulu obufanelekileyo bezinto eziluhlaza. Eli nyathelo lijolise ekususeni ukungcola, ukuqinisekisa ubunyulu kunye nobukhulu obufanayo bezinto eziluhlaza, ngaloo ndlela kubekwa isiseko seenkqubo ezilandelayo.
Ukugaya: Izinto zekhabhoni ze-petroleum coke ezinobukhulu obufanelekileyo zifakwa kwisithando sobushushu obuphezulu ukuze zigalelwe i-calcium. Le nkqubo isusa umswakama kunye nezinto eziguquguqukayo kwizinto eziluhlaza, iphucula iipropati zazo ze-physicochemical, ezifana noxinano lokwenyani kunye nokumelana. Ukongeza, ukugaya i-calcium kunceda ekucoceni nasekuphuculeni i-petroleum coke, iphucula ixabiso layo le-calorific kunye neepropati zomzimba.
Ukutyumza nokuHlola: Emva kokuba i-calcination iqale, amaqhuma e-petroleum coke kufuneka apholiswe ukuze kuncitshiswe ubushushu bawo. Emva koko, kwenziwa uhlengahlengiso loomatshini ukuze kususwe iimveliso ezingahambelaniyo, ukuqinisekisa umgangatho wemveliso. Emva koko, i-petroleum coke epholileyo ityumzwa ngakumbi kwaye ihlolwe ukuze kuhlangatyezwane neemfuno zokusasazwa kobukhulu bamasuntswana kwiinkqubo ezilandelayo.
Ukudibanisa kunye nokuxova: Ngokweemfuno zokwenziwa kwemveliso, i-coke ye-petroleum ene-calcium ixutywa ne-binder (efana ne-coal tar pitch) ngomlinganiselo othile. Emva koko umxube uxutywa kubushushu obuthile ukuqinisekisa ukuxubana okufanayo kwaye uxovwe ube yi-malleable paste. Eli nyathelo linceda ukuphucula ukuqina komxube, okwenza i-malleable paste efanayo elungele ukubumba.
Ukubumba: Intlama ye-carbonaceous exovwe ngomxube iguqulwa yiplastiki phantsi kwamandla angaphandle asetyenziswa zizixhobo zokubumba, ekugqibeleni yenze i-compact eluhlaza enobume obuthile, ubungakanani, uxinano, kunye namandla. Ngexesha lenkqubo yokubumba, izinto ezifana nohlobo lwe-mold, ukukhethwa kwezixhobo, kunye nolawulo lomgangatho wemveliso kufuneka ziqwalaselwe ukuqinisekisa ukuba umgangatho we-compact eluhlaza uyahlangabezana neemfuno.
Ukubhaka: Iicompacts eziluhlaza zifakwa kwisithando sobushushu esenzelwe ngokukodwa kwaye zinyangwa ngobushushu obuphezulu phantsi kokhuseleko lwezizalisi ezithile. Inkqubo yokubhaka ibangela ukuba i-coal tar pitch kwi-compacts eziluhlaza ibe yi-carbonize, yenze i-pitch coke eqinisa i-carbonaceous aggregate kunye namasuntswana e-powder kunye. Iimveliso ze-baked carbon zibonisa amandla aphezulu oomatshini, ukumelana okuphantsi, kunye nozinzo oluhle lobushushu kunye neekhemikhali.
Unyango lweGraphitization: Iziqwenga ze-coke zepetroleum ezibhakiweyo zifakwa kwisithando segraphitization kwaye ziphathwe ngegraphitization kubushushu obuphezulu (ngesiqhelo yi-2800℃-3000℃). Ngexesha lale nkqubo, ukungcola okuseleyo kwiziqwenga ze-coke zepetroleum kuyawohloka kancinci kancinci, ngelixa iiathom zekhabhoni zihlengahlengiswa ukuze zenze isakhiwo segraphite esixineneyo. Unyango lweGraphitization luphucula kakhulu ukuhanjiswa kombane, ukuhanjiswa kobushushu, kunye nokuzinza kweekhemikhali zezinto zekhabhoni, ekugqibeleni kuvelise i-coke ye-coke ye-graphitized ecocekileyo kakhulu.
Ukucutshungulwa nokuPakisha kakuhle: Emva kokulungiswa kwegraphitization, i-petroleum coke icutshungulwa kakuhle (njengokuhluzwa nokuhlengahlengiswa) kunye nokupakishwa ngaphambi kokuba ilungele ukuthengiswa. Ezi mveliso zisetyenziswa kakhulu ekwenzeni iimveliso ezahlukeneyo zoshishino, kubandakanya ii-electrodes, ii-cathodes, kunye namafutha ebhoyila.
