Iyini i-Graphite Electrode?

I-electrode ye-graphitewuhlobo lwe-electrode esetshenziswa ekusetshenzisweni kukagesi wezinga lokushisa eliphezulu, ikakhulukazi ekukhiqizeni insimbi ngenqubo ye-electric arc furnace (EAF).Ama-electrode e-graphite ayizingxenye ezibalulekile kule ndlela yokwenza insimbi, lapho ehambisa khona amandla kagesi ukuze ancibilikise izinsimbi ezilahliwe nezinye izinto zokusetshenziswa.

Ama-electrode e-graphite ngokuvamile enziwa ngengxube ye-petroleum coke, i-pitch, nezinye izinto ze-carbonaceous.Lezi zinto ziyacindezelwa futhi zibhakwa ukuze zenze i-electrode.I-electrode ye-graphite ewumphumela ine-conductivity ephezulu kagesi, ukumelana nokushisa okuphezulu, namandla amahle okusebenza, okwenza ilungele ukusetshenziswa ezimweni ezimbi kakhulu zesithando somlilo se-arc kagesi.

Inqubo yesithando somlilo we-arc kagesi iyindlela ethandwayo yokukhiqiza insimbi ngenxa yokuguquguquka kwayo kanye nekhono lokusebenzisa izinto ezihlukahlukene zokusetshenziswa.Kule nqubo, insimbi eyi-scrap nezinye izinto zokusetshenziswa ziyancibilika kusetshenziswa ukushisa okukhiqizwa ku-arc kagesi phakathiama-electrode e-graphitekanti insimbi iyancibilika.Amandla kagesi adlula kuma-electrode e-graphite, enze ukushisa okukhulu okuncibilikisa izinto, okuvumela ukungcola ukuba kususwe futhi izakhi ze-alloying zengezwe ukuze kukhiqizwe izinga lensimbi elifiswayo.

Ama-electrode e-graphite eza ngosayizi namabanga ahlukahlukene ukuze ahlangabezane nezidingo ezithile zezinhlelo zokusebenza ezahlukene zokwenza insimbi.Ububanzi nobude bama-electrode kungahluka kuye ngokuthi umthamo kanye nomklamo wesithando somlilo we-arc kagesi.Ukwengeza, ikhwalithi nokubunjwa kwe-electrode ye-graphite, okuhlanganisa ukuminyana kwayo kanye nokuqhutshwa kokushisa, kudlala indima ebalulekile ekusebenzeni kahle nasekusebenzeni kwenqubo yokwenza insimbi.

Esinye sezici ezibalulekile ekusebenzeni kwama-electrode e-graphite ukumelana kwawo ne-oxidation kanye nokushaqeka kokushisa.Phakathi nenqubo yokwenza insimbi, ama-electrode e-graphite achayeka emazingeni okushisa adlulele kanye nokusabela kwamakhemikhali.Ikhono lama-electrode okumelana nalezi zimo ezinzima ngaphandle kokuwohloka kubalulekile ekugcineni ukusebenza okuzinzile nokuthembekile kwesithando somlilo se-arc kagesi.

Ama-electrode e-graphite nawo adlala indima ebalulekile ezindlekweni kanye nokusebenza kahle kwamandla okukhiqizwa kwensimbi.Ngokuhlinzeka nge-conductivity kagesi ephumelelayo kanye nokudlulisa ukushisa, ama-electrode e-graphite aphezulu afaka isandla ekunciphiseni ukusetshenziswa kwamandla nokuthuthukisa ukusebenza kokuncibilika kwesithando somlilo se-arc kagesi.Lokhu, futhi, kungaholela ekongeni izindleko kanye nezinzuzo zemvelo emisebenzini yokwenza insimbi.

Ngaphezu kokusetshenziswa kwawo okuyinhloko embonini yensimbi, ama-electrode e-graphite anezinhlelo zokusebenza kwezinye izinqubo ezishisa kakhulu, njengokukhiqizwa kwama-ferroalloys, insimbi ye-silicon, namanye ama-alloys akhethekile.Lezi zinqubo ziphinde zithembele ezintweni zikagesi nezishisayo zama-graphite electrode ukuze kuzuzwe imiphumela oyifunayo.

Sekukonke, ama-electrode e-graphite ayizingxenye ezibalulekile ekusetshenzisweni kukagesi wezinga eliphezulu lokushisa, ikakhulukazi ekwenzeni insimbi ngenqubo yesithando somlilo se-arc kagesi.Inhlanganisela yabo eyingqayizivele ye-conductivity kagesi, ukumelana nokushisa, namandla emishini kubenza babaluleke kakhulu ekuncibilikiseni nasekucwengiseni insimbi nezinye izinto.Njengoba ukukhiqizwa kwensimbi kuqhubeka nokuvela, isidingo sama-electrode e-graphite wekhwalithi ephezulu kulindeleke ukuthi sihlale siqinile, siqhubekisele phambili intuthuko ekubunjweni kwawo, ukusebenza kwawo, kanye nokusimama embonini yokwenza insimbi.
