Ama-electrode e-graphiteidlala indima ebalulekile embonini yesimanje, ikakhulukazi emkhakheni wokwenza insimbi.Ngaphandle kwalezi zingxenye ezibalulekile, yonke inqubo yokukhiqiza insimbi izoma ukugaya.Ngenxa yalokho, isidingo sabakhiqizi be-graphite electrode seqophelo eliphezulu eminyakeni yamuva nje.
Ama-electrode e-graphite asetshenziswa ngokuyinhloko kuma-arc arc kagesi (ama-EAF) naseziko lokuhlinzeka ngogesi wokuncibilikisa izinsimbi ezilahliwe noma ezinye izinto zokusetshenziswa.Lawa ma-electrode ahlinzeka ngamandla kagesi adingekayo ukuze akhiqize ukushisa okukhulu okudingekayo ukuze kuncibilikiswe insimbi futhi kuqalise ukusabela kwamakhemikhali ukuze kukhishwe ukungcola ensimbi encibilikisiwe.Ngomsebenzi obalulekile onjalo, ukukhetha komkhiqizi we-graphite electrode kuba okubaluleke kakhulu kubakhiqizi bensimbi.
Igraphite electrode inqubo yokukhiqizaiqala ngokukhetha ngokucophelela izinto zokusetshenziswa, ikakhulukazi i-petroleum coke ne-needle coke.Lezi zinto zifaka ukushisa okukhulu ukuze zisuse ukungcola, okuholela ekukhiqizeni okuphezulu kwe-carbonaceous.I-coke ehlanzekile ihlanganiswa ne-coal tar pitch futhi ibunjwe ibe yisimo se-electrode oyifunayo kusetshenziswa inqubo yokubumba.Kamuva, umkhiqizo osuphelile ubhakwa emazingeni okushisa aphakeme kakhulu ukuze uwuguqule ube isakhiwo esiqinile sekhabhoni.Imijikelezo eminingi yomshini kanye nokuhlolwa okwengeziwe kwekhwalithi kuyenziwa ukuze kuqinisekiswe ukuthi ama-electrode ahlangabezana nokucaciswa okudingekayo.
Kodwa-ke, ukuba ngumkhiqizi we-graphite electrode akunazo izinselele.Okokuqala, imboni ibhekene nokukhathazeka okukhulu kwezemvelo ngenxa yemvelo edla kakhulu ikhabhoni yenqubo yokukhiqiza.Ngokubona lokhu, abakhiqizi bebetshala imali ocwaningweni nasekuthuthukisweni ukuze banciphise indawo yabo yekhabhoni futhi banciphise ukuphehlwa kwemfucuza.Ukwengeza, ukutholakala nezindleko zezinto ezingavuthiwe zekhwalithi ephezulu yizinto ezibalulekile ezithinta inqubo yokukhiqiza.Noma yikuphi ukuphazamiseka ochungechungeni lokuhlinzeka ngezinto ezingavuthiwe kungaba nomthelela omkhulu ekukhiqizeni ama-electrode e-graphite.
Ngaphandle kwemboni yokwenza insimbi, ama-electrode e-graphite nawo athola ukusetshenziswa kweminye imikhakha.Isibonelo, ziyizingxenye ezibalulekile ezithandweni zikagesi ze-arc ezisetshenziselwa ukuncibilikisa i-aluminium esele.Isidingo se-aluminium sikhula ngokuqhubekayo ngenxa yezakhiwo zayo ezingasindi kanye nokusetshenziswa okusabalele emikhakheni yezokuthutha neyokwakha.Abakhiqizi be-graphite electrode badlala indima ebalulekile ekuqinisekiseni ukutholakala kwama-electrode okusimeme ukuze kuhlangatshezwane nalesi sidingo esikhulayo.
Ngaphezu kwalokho, ama-electrode e-graphite abalulekile ekukhiqizeni insimbi ye-silicon namanye ama-alloys asekelwe ku-silicon.I-silicon iyingxenye ebalulekile ekwenziweni kwemikhiqizo ehlukahlukene ye-elekthronikhi, ama-solar panel, ngisho nemishini yezokwelapha.Njengoba ubuchwepheshe buthuthuka kanye nesidingo sale mikhiqizo sikhuphuka, ukubaluleka kwabakhiqizi abathembekile be-graphite electrode kuba sobala nakakhulu.
Ekuphetheni,abakhiqizi be-graphite electrodebangabadlali ababalulekile emkhakheni wezimboni, ngemikhiqizo yabo esekela izinqubo ezibalulekile ezihlukahlukene.Ubuchwepheshe babo ekukhiqizeni ama-electrode ekhwalithi ephezulu buqinisekisa ukusebenza kahle kwezithando zikagesi ze-arc kanye nama-ladle furnaces.Naphezu kwezinselelo ezihlobene nomthelela wemvelo kanye nokutholakala kwempahla eluhlaza, imboni iyaqhubeka nokuthuthuka, ilwela izinqubo ezisimeme kanye nobuchwepheshe obusha.Njengoba isidingo sensimbi, i-aluminium, ne-silicon-based alloys siqhubeka sikhula, iminikelo yabakhiqizi be-graphite electrode ibalulekile ekukhuleni nasekuthuthukisweni kwale mikhakha.
