550mm amandla aphezulu e-graphite electrode
I-HP graphite electrode yenziwe ikakhulukazi nge-petroleum coke ne-coke yenaliti, Iyakwazi ukuthwala ukuminyana kwamanje 18-25A/cm2. Yakhelwe amandla aphezulu okwenza insimbi ye-arc yomlilo kagesi.
Izindlela zesimanje zokwenza insimbi ngokuyinhloko zihlanganisa i-converter steelmaking kanye nokwenza insimbi yesithando somlilo kagesi. Umehluko oyisisekelo kakhulu phakathi kwendlela yokwenza insimbi yomlilo kagesi kanye nendlela yokwenza insimbi yokuguqulela ukuthi indlela yokwenza insimbi yesithando sikagesi isebenzisa amandla kagesi njengomthombo wokushisa, futhi indlela yokwenza insimbi ye-arc yesithando somlilo iyona esetshenziswa kakhulu.
I-EAF steelmaking isekelwe ku-arc kagesi ekhiqizwe ukukhipha phakathi kwe-electrode kanye nokushaja, eguqula amandla kagesi abe amandla ashisayo ekukhanyeni kwe-arc, futhi isebenzisa isenzo esiqondile semisebe ne-arc ukushisa nokuncibilikisa insimbi ne-slag ukuze incibilike. insimbi nama-alloys ezingoma ezihlukahlukene.

Ukwakhiwa kwe-electrode ye-graphite
1.I-petroleum coke imnyama futhi inezimbotshana, ikhabhoni iwukwakheka okuyinhloko, kanti umlotha uphansi kakhulu, ngokuvamile ungaphansi kuka-0.5%.
I-petroleum coke ingahlukaniswa ngezinhlobo ezimbili ze-coke eluhlaza kanye ne-coke e-calcined ngokuya ngezinga lokushisa lokwelapha ukushisa. Eyangaphambili iqukethe inani elikhulu lezinto eziguquguqukayo futhi inamandla aphansi emishini. I-coke e-calcined itholakala ngokubala i-coke eluhlaza.
I-petroleum coke ingahlukaniswa nge-coke ephezulu yesibabule (enokuqukethwe kwesulfure ngaphezu kuka-1.5%), i-coke yesulfure ephakathi (ene-sulphur content 0.5% -1.5%), ne-coke yesulfure ephansi (enokuqukethwe kwesulfure ngaphansi kuka-0.5%) ngokwezinga lesulfure. Ama-electrode e-graphite neminye imikhiqizo ye-graphite yokwenziwa ngokuvamile akhiqizwa kusetshenziswa i-coke yesulfure ephansi.
I-2.Inaliti ye-coke iwuhlobo lwe-coke yekhwalithi ephezulu ene-fiber texture ebonakalayo, ikakhulukazi i-coefficient ephansi yokwandisa okushisayo kanye ne-graphitization elula. Ngakho-ke, i-needle coke iwukhiye wezinto ezingavuthiwe zokukhiqiza ama-electrode e-graphite anamandla amakhulu noma aphezulu afakwe nge-resistivity ephansi, i-coefficient encane yokwandisa ukushisa, kanye nokumelana nokushaqeka okuhle kokushisa.
3.I-Coal pitch ingenye yemikhiqizo eyinhloko yetiyela lamalahle ngemva kokucubungula okujulile. Kuyingxube yama-hydrocarbon amaningi. I-pitch yamalahle isetshenziswa njenge-binder kanye nempahla yokumithisa. Ukusebenza kwayo kunethonya elikhulu kwikhwalithi yama-electrode e-graphite.
