Iielectrode zegraphite zidlala indima ebalulekileyo kwiinkqubo zanamhlanje zokusulungekisa isinyithi kunye neenkqubo zokunyibilikisa.Yenziwe ngekhwalithi ephezulu, i-high-conductive material graphite, la ma-electrodes asetyenziswa njenge-conductive medium kwi-electric arc furnaces (EAFs) kunye ne-ladle furnaces (LFs).Iimpawu zabo ezikhethekileyo kunye neempawu zenza ukuba zibe zikhetho ezifanelekileyo kwiqondo lokushisa eliphezulu, izicelo eziphezulu zangoku.
Enye yezona zinto zibalulekileyo kwii-electrode zegraphite kukuzinza kwazo okuhle kakhulu kwe-thermal.Ziyakwazi ukumelana namaqondo obushushu aphezulu kakhulu ngaphandle kokulahlekelwa ingqibelelo yesakhiwo okanye ukuqhuba.Oku kubalulekile kwiinkqubo zokusulungekiswa kwesinyithi nakwiinkqubo zokunyibilikisa apho amaqondo obushushu anokufikelela kumawaka aliqela ngokukaCelsius.I-electrode yegraphite inokusingatha ngokufanelekileyo ezi meko zinzima, iqinisekisa ukusebenza ngokufanelekileyo nangokuthembekileyo kwezithando.
Olunye uphawu oluphambili lwei-electrode yegraphitekukuxhathisa kwabo okuphezulu kwi-oxidation kunye nokubola.Ebudeni benkqubo yokusulungekiswa kwesinyithi, kubakho imichiza eyahlukahlukeneyo, edla ngokubandakanya izinto ezonakalisa kakhulu.Iielectrode zegraphiteukuchasana ne-oxidation kunye ne-corrosion iqinisekisa ubomi obude kunye nokusebenza okungaguqukiyo kwezi ndawo ezinzima.
Ukongezelela, i-electrode yegraphite ine-coefficient ephantsi yokwandiswa kwe-thermal.Oku kuthetha ukuba babonisa utshintsho oluncinci xa bevezwe kumaqondo obushushu.Uzinzo olunjalo lubalulekile kwizicelo zemizi-mveliso, njengoko nakuphi na ukwandiswa okanye ukufinyezwa kunokubangela uxinzelelo lomatshini kunye nomonakalo onokwenzeka kwii-electrode.I-coefficient ephantsi yokwandiswa kwe-thermal ye-graphite electrode iqinisekisa ukunyaniseka kwesakhiwo kunye nokuqina nakwiimeko zokusebenza ezinzima.
I-conductivity ekhethekileyo yee-electrode zegraphite nazo zifanelekile ukugqamisa.I-graphite yinto eqhuba kakhulu, evumela ukuhanjiswa okusebenzayo kunye nokusebenzayo kwamandla ombane ngaphakathi kwesithando somlilo.Le conductivity ibalulekile kwi-EAF kunye ne-LFs, apho ubuninzi bombane obufunekayo ukunyibilikisa isinyithi kwaye uqhube inkqubo yokucoca.I-conductivity ephezulu ye-graphite electrode iqinisekisa ukulahlekelwa kwamandla amancinci kunye nokusebenza ngokufanelekileyo kwezi ziko.
Iielectrode zegraphite zibonelela ngeenzuzo ezahlukeneyo kunye neenzuzo ngaphezulu kwezinye izinto ezisetyenziswa ngokuqhelekileyo ekusulungekisweni kwesinyithi kunye neenkqubo zokunyibilikisa.Ngokomzekelo, xa kuthelekiswa nee-electrode zobhedu, i-electrode yegraphite inexabiso eliphantsi kwaye inokusingatha amaqondo obushushu aphezulu.Kananjalo ziyakwazi ukumelana neekhemikhali, zizenza zilungele uluhlu olubanzi lwezicelo.Ngaphaya koko, i-electrode yegraphite inobomi obude kwaye ifuna ukugcinwa okuncinci, okukhokelela ekongeni kweendleko ezinkulu ekuhambeni kwexesha.
GI-raphite electrode ineseti ekhethekileyo yeempawu ezizenza zibaluleke kakhulu kwiinkqubo zangoku zokusulungekiswa kwesinyithi kunye neenkqubo zokunyibilikisa.Ukuzinza kwabo kwe-thermal, ukuxhathisa kwi-oxidation kunye ne-corrosion, i-coefficient ephantsi yokwandiswa kwe-thermal, kunye ne-conductivity egqwesileyo ibenza bahluke kwezinye izinto.Ngokudityaniswa neendleko-zokusebenza kunye nobomi obude, i-electrode yegraphite iyona nto ikhethwayo yobushushu obuphezulu, usetyenziso oluphezulu lwangoku kumashishini emhlabeni jikelele.Nokuba kukwiziko zombane zearc okanye kwiziko leladle, iielectrode zegraphite zidlala indima ebalulekileyo ekuqinisekiseni ukusulungekiswa kwesinyithi ngendlela esebenzayo, ethembekileyo nezinzileyo.
