Ama-electrode e-graphiteziyizingxenye ezibalulekile embonini yokwenza insimbi neyokucubungula insimbi. Lawa ma-electrode asetshenziswa kakhulu kuma-arc arc kagesi (EAF) nasezithandweni ze-ladle zokukhiqiza insimbi nezinye izinsimbi. Izakhiwo eziyingqayizivele zama-electrode e-graphite ziwenza alungele ukusetshenziswa okunokushisa okuphezulu, futhi adlala indima ebalulekile ekukhiqizeni okuphumelelayo nokungabizi kwensimbi yezinga eliphezulu. Kulesi sihloko, sizohlola ukusetshenziswa okuhlukahlukene kwama-electrode e-graphite nokubaluleka kwawo embonini yokucubungula insimbi nensimbi.
I-Electric Arc Furnaces (EAF)
Esinye sezicelo eziyinhloko zama-graphite electrode kusezithandweni zikagesi ze-arc (EAF) zokukhiqiza insimbi. Ama-EAF asetshenziselwa ukuncibilikisa izinsimbi ezilahliwe nezinye izinto zokusetshenziswa ukukhiqiza insimbi entsha. Ama-electrode e-graphite asetshenziselwa ukuqhuba ugesi futhi akhiqize i-arc enezinga lokushisa eliphezulu edingekayo ukuze kuncibilike izinto zokusetshenziswa. Ama-electrode acwiliswa ensimbi encibilikisiwe futhi anesibopho sokudlulisa amandla kagesi eshadini, ngaleyo ndlela ayishise futhi ayincibilikise. Ukusetshenziswa kwama-electrode e-graphite kuma-EAF kuvumela ukulawula okunembile kwenqubo yokuncibilika futhi kuqinisekisa ukudluliswa kwamandla okuphumelelayo, okuholela ekukhiqizweni kwensimbi ephezulu.
Ladle Furnaces
Ama-ladle furnaces angenye indawo ebalulekile yokufaka isicelo sama-graphite electrode. Lezi ziko zisetshenziselwa ukucwengisiswa kwensimbi okwesibili, lapho insimbi encibilikisiwe evela enqubweni yokuqala yokwenza insimbi iphinde ilashwe ukuze kuzuzwe ukwakheka kwamakhemikhali kanye nezinga lokushisa elifunekayo. Ama-electrode e-graphite asetshenziswa ezithandweni ze-ladle ukunikeza ukushisa okudingekayo kwezinqubo zokucwenga kanye ne-alloying. Ama-electrode adlala indima ebalulekile ekugcineni izinga lokushisa lensimbi encibilikisiwe futhi enze kube lula ukungezwa kwezakhi ezihlukahlukene ze-alloying kanye nokuguquguquka. Ukusetshenziswa kwama-electrode e-graphite ezithandweni ze-ladle kuqinisekisa ukulawula okunembile phezu kwenqubo yokucwenga, okuholela ekukhiqizeni izinga eliphezulu, insimbi ehlanzekile.
Ezinye Izinqubo Zokwenza Insimbi
Ngokungeziwe kuma-EAF nama-ladle furnaces, ama-electrode e-graphite athola ukusetshenziswa kwezinye izinqubo zokwenza insimbi njengama-submerged arc furnaces (SAF) nezinye izindlela zokukhiqiza zensimbi ezikhethekile.Izithando zama-arc ezicwilisiweasetshenziselwa ukukhiqizwa kwama-ferroalloys, i-silicon metal, nezinye izinsimbi ezikhethekile. Kusetshenziswa ama-electrode e-graphite kulawa ma-arcs ukuze kukhiqizwe ama-arcs anezinga lokushisa eliphezulu adingekayo ukuze kuncibilikiswe futhi kucwengwe izinto zokusetshenziswa. Ukusetshenziswa kwama-electrode e-graphite ezithandweni ze-arc ezingaphansi kwamanzi kwenza ukushisa okusebenzayo nokulawulwayo, okuholela ekukhiqizeni izinsimbi ezikhethekile zokuhlanzeka okuphezulu.
I-Aluminium nokunye Ukukhiqizwa Kwezinsimbi Ezingeyona Insimbi
Ama-electrode e-graphite awanqunyelwe ezinhlelweni zokwenza insimbi futhi asetshenziswa kabanzi ekukhiqizeni izinsimbi ezingenayo ayoni njenge-aluminium, ithusi, namanye ama-alloys. Embonini ye-aluminium, ama-electrode e-graphite asetshenziswa ekukhiqizeni i-aluminium eyinhloko ngenqubo ye-Hall-Héroult. Ama-electrode acwiliswa esitokisini se-electrolytic futhi anesibopho sokudlulisa amandla kagesi nge-alumina ukuze kube lula inqubo ye-electrolysis, okuholela ekukhiqizweni kwe-aluminium ehlanzekile. Ama-electrode e-graphite nawo asetshenziswa ekuncibilikiseni nasekucwengisiseni ithusi nezinye izinsimbi ezingenayo ayoni, lapho edlala indima ebalulekile ekuhlinzekeni ukushisa okudingekayo kanye nokuhamba kukagesi ngenqubo yokukhiqiza.
Izicelo zamakhemikhali nezezimboni
Ngaphandle kwezimboni zokucubungula insimbi nensimbi, ama-electrode egraphite athola ukusetshenziswa ezinqubweni ezihlukahlukene zamakhemikhali nezimboni. Zisetshenziswa ezintweni zokushisa zikagesi ezithandweni zokushisa okuphezulu, ukushisa kokumelana, nezinye izinhlelo zokusebenza zokucubungula ezishisayo. Ama-electrode e-graphite nawo asetshenziswa ekukhiqizeni amakhemikhali athile nezinto zokwakha ngezinqubo ezifana ne-electrochemical synthesis kanye ne-electrolysis. Inhlanganisela eyingqayizivele ye-thermal conductivity ephezulu, ukumelana nogesi okuphansi, nokungabi namandla kwamakhemikhali kwenza ama-electrode e-graphite afanelekele uhla olubanzi lwezinhlelo zokusebenza zezimboni lapho izinga lokushisa eliphezulu kanye nezindawo ezibolayo zihilelekile.
Izinto Ezithuthukile Nocwaningo
Ama-electrode e-graphite nawo asetshenziswa ekukhiqizeni izinto ezithuthukisiwe nasemisebenzini yocwaningo nentuthuko. Asetshenziswa ekuhlanganiseni izinto ezisekelwe ku-carbon, njenge-graphene ne-carbon nanotubes, ngezinqubo ezifana ne-chemical vapor deposition (CVD). Ama-electrode e-graphite adlala indima ebalulekile ekunikezeni umthombo wekhabhoni odingekayo namandla ashisayo ukuze kukhule lezi zinto ezithuthukisiwe. Ukwengeza, ama-electrode e-graphite asetshenziswa ezinhlelweni ezihlukene zocwaningo, okuhlanganisa i-plasma physics, isayensi yezinto ezibonakalayo, nokuhlolwa kwezinga lokushisa eliphezulu, lapho ukubekezelelana kwawo kwezinga lokushisa eliphezulu kanye nokusebenza kukagesi kubalulekile ekwenzeni izivivinyo nokukhiqiza izindawo ezilawulwayo ezishisayo.
Ukucatshangelwa Kwemvelo
Ukusetshenziswa kwama-electrode e-graphite ezinqubweni zezimboni kuphakamisa ukucatshangelwa kwemvelo, ikakhulukazi mayelana nokusetshenziswa kwamandla kanye nokukhishwa kwegesi. Nakuba ama-electrode e-graphite ebalulekile ekusetshenzisweni kwezinga lokushisa eliphezulu, ukusebenza kahle kwamandla kwezinqubo lapho asetshenziswa khona kuyisici esibalulekile ekunciphiseni umthelela wendawo. Imizamo iyenziwa yokuthuthukisa idizayini nokusebenza kwezithando zomlilo zikagesi nezinye izinqubo zezimboni ukuze kuncishiswe ukusetshenziswa kwamandla kanye nokukhipha umoya. Ukwengeza, intuthuko ezintweni zokwenziwa kwama-electrode kanye nezinqubo zokukhiqiza kuhloswe ngayo ukuthuthukisa ukusimama nokusebenza kwemvelo kwama-graphite electrode.
Ama-electrode e-graphite ayizingxenye ezihlukahlukene futhi ezibalulekile ezinhlobonhlobo zezinhlelo zokusebenza zezimboni, ikakhulukazi ezimbonini zensimbi nezinsimbi. Inhlanganisela yazo eyingqayizivele yezakhiwo, okuhlanganisa ukuguquguquka okuphezulu kwe-thermal, ukuqhutshwa kukagesi, nokungangeni kwamakhemikhali, kuzenza zibe zilungele izindawo ezishisa kakhulu nezifunayo. Kusukela steelmaking izinqubo ezifanaama-arc kagesikanye nezithando zomlilo ekukhiqizeni insimbi engeyona ayoni, ukusetshenziswa kwamakhemikhali, kanye nokuhlanganiswa kwezinto ezithuthukisiwe, ama-electrode e-graphite adlala indima ebalulekile ekusizeni izinqubo ezisebenzayo nezilawulwayo zokushisisa nokucwengisisa. Njengoba izimboni ziqhubeka nokuvela futhi zenza izinto ezintsha, isidingo sama-electrode e-graphite wekhwalithi ephezulu kanye nezicelo zawo kulindeleke ukuthi sikhule, siqhubekisele phambili inqubekela phambili ezintweni, izinqubo, kanye nokusimama kwemvelo.
