Iielectrode zegraphite, ezidla ngokubizwa ngokuba ziigraphite rod, zidlala indima ebalulekileyo kumashishini ahlukeneyo ngenxaIimpawu zegraphite electrodekunye nezicelo ezininzi.
I:I-electrodes yegraphite isetyenziswa ikakhulu kwii-arc furnaces (EAFs) kwimveliso yentsimbi.
Ii-EAFs ziya zithatha indawo yeendlela zemveli ngenxa yokusebenza kwazo kunye nefuthe eliphantsi kokusingqongileyo.Iielectrode zegraphite zisebenza njengee-conductor zombane, ezivumela ukuguqulwa kwamandla ombane kubushushu obukhulu nge-arc yombane.Obu bushushu busetyenziselwa ukunyibilikisa iintsimbi ezilahliweyo kunye nokuvelisa iibhilithi zentsimbi ezikumgangatho ophezulu, imivalo kunye nezinye iimveliso zentsimbi.
II:Olunye usetyenziso olubalulekileyo lwee-electrode zegraphite kukuveliswa kwentsimbi.
Kwinkqubo efanayo yokwenza intsimbi, iielectrode zegraphite zivelisa ubushushu obuyimfuneko ukuze kunyibilike intsimbi nokususa ukungcola.Emva koko intsimbi etyhidiweyo igalelwa kwiimilo ezahlukahlukeneyo, njengemibhobho, iipleyiti nezinto ezixutywe noomatshini.Iielectrode zegraphite zenza ulawulo oluchanekileyo lobushushu, luqinisekisa ukuveliswa kwentsimbi eneempawu ezifunwayo kunye neempawu.
III:Ii-electrode zegraphite zikwasetyenziswa kakhulu kwimveliso yesimbi yesilicon kunye neeferroalloys.
Insimbi ye-silicon, icandelo eliphambili ekwenzeni i-semiconductors kunye neeseli zelanga, ziveliswa ngenkqubo yokunciphisa i-carbothermic.Le nkqubo ibandakanya ukusabela kwequartz ngekhabhoni kumaqondo obushushu aphezulu.Iielectrode zegraphiteukubonelela ngobushushu obufunekayo ukuququzelela le ndlela yokusabela, okubangela ukuveliswa kwentsimbi ye-silicon ecocekileyo.
IV: Ukuveliswa kwee-ferroalloys, ezifana ne-ferrosilicon kunye ne-ferrochrome, kuxhomekeke kwi-electrode yegraphite kwiinkqubo zabo zokushisa okuphezulu.
IiFerroalloys zibalulekile kushishino lwentsimbi njengoko zinika iipropathi ezithile ezinjengobulukhuni kunye nokumelana nomhlwa kwintsimbi.Iielectrode zegraphite zenza ukuba kudityaniswe ore zentsimbi ezahlukeneyo kunye nekhabhoni, zenza iiferroalloys ezihlangabezana neemfuno ezithile zomxube.
V:Ii-electrode zegraphite zifumana usetyenziso kwimveliso yealuminiyam.
Kwinkqubo yeHolo-Héroult, i-aluminium ikhutshwe kwi-alumina ore ngokusebenzisa i-electrolysis.Iielectrode zegraphite zisebenza njenge cathodes kule nkqubo,ukuqhuba umbanekunye nokuququzelela ukucuthwa kwe-aluminam kwi-aluminiyam.Oku kuqinisekisa ukuveliswa okuqhubekayo kwe-aluminiyam, okwenza i-electrode yegraphite iyimfuneko kwishishini le-aluminium.
VI:Ii-electrode zegraphite nazo ziyaqeshwa kushishino lwe-electrochemical kwiinkqubo ezinje ngokucoca i-electrorefining kunye ne-electrowinning.
I-Electrorefining isetyenziselwa ukuhlambulula isinyithi esingcolileyo ngokusebenzisa i-electroplating, ngelixa i-electrowinning iqeshwe ukukhupha isinyithi kwi-ores.I-electrode yegraphite ibonelela nge-conductivity yombane efunekayo kwezi nkqubo, ivumela ukwahlula, ukucocwa kunye nokutsalwa kweentsimbi ezahlukeneyo.
VII:Ii-electrode zegraphite zisetyenziswa ekuvelisweni kweebhetri, ngokukodwa iibhetri ze-lithium-ion.
I-graphite iyinxalenye ephambili ye-anode kwiibhetri ze-lithium-ion, apho igcina kwaye ikhuphe i-lithium ion ngexesha lokutshaja kunye nokukhupha imijikelezo.Ukusebenza kunye nokusebenza kweebhetri ze-lithium-ion kuxhomekeke kakhulu kumgangatho kunye nokubunjwa kwee-electrode zegraphite ezisetyenzisiweyo.
VIII:Ii-electrode zegraphite zisetyenziswa kwishishini lokwenziwa kweglasi.
Iziko lokunyibilika kweglasi lifuna amaqondo obushushu aphezulu ukuguqula izinto ezikrwada zibe yiglasi etyhidiweyo.Iielectrode zegraphite zidlala indima ebalulekileyo ekuboneleleni ngobushushu obufunekayo kule nkqubo.Ukukwazi kwabo ukumelana namaqondo obushushu aphezulu kunye nemisinga yombane ephezulu kubenza balungele imisebenzi yokunyibilika kweglasi.
IX:I-electrodes yegraphite isetyenziswa ngokuqhelekileyo kwinkqubo ye-EDM (Electrical Discharge Machining).
Kwi-EDM, ukukhutshwa kombane okulawulwayo phakathi kwe-electrode kunye ne-workpiece kususa izinto eziphathekayo kwi-workpiece, ukuvumela ukuba kuqulunqwe imilo eyinkimbinkimbi kunye nechanekileyo.I-electrode ye-graphite, kunye ne-thermal conductivity egqwesileyo kunye nokuchasana kombane, yenza ukuba imisebenzi ye-EDM isebenze kakuhle kwaye ichanekileyo.
Ukuqukumbela, i-electrode yegraphite inoluhlu olubanzi lwezicelo kuwo wonke amashishini ahlukeneyo.Ukusuka kwimveliso yentsimbi kunye nentsimbi ukuya kwimveliso yeebhetri kunye neglasi, i-electrode yegraphite ibalulekile ekuququzeleleni iinkqubo zobushushu obuphezulu kunye nokuqinisekisa umgangatho kunye nokusebenza kakuhle kweemveliso zokugqibela.Iipropati zabo ezizodwa zibenza babe yinxalenye eyimfuneko kwiinkqubo ezininzi zemizi-mveliso, benegalelo kwinkqubela phambili yezobuchwepheshe kunye nophuhliso oluzinzileyo kumacandelo ahlukeneyo.
