Iielectrode zegraphite ezenziweyoziye zavela njengenxalenye ebalulekileyo kumashishini ahlukeneyo ngenxa yeepropathi zazo ezikhethekileyo kunye nezicelo eziguquguqukayo.Ezi electrode zisetyenziswa ikakhulu kwi-steelmaking ye-arc yombane, eyona nkqubo ibalulekileyo ekuveliseni intsimbi.Nangona kunjalo, ukusetyenziswa kwazo kudlulela ngaphaya nje kweshishini lentsimbi, njengoko zikwaqeshwe kwisinyithi esingenawo i-ferrous, njengemveliso ye-aluminium, kunye nokuveliswa kweekhemikhali kunye nezixhobo ezithile.
Kwi-steelmaking ye-arc yombane, i-electrode yegraphite eyenziweyo idlala indima ebalulekileyo ekuguqulweni kwe-scrap okanye i-iron encitshisiweyo ngqo ibe yintsimbi engamanzi.Ii-electrode zisetyenziselwa ukuhambisa umbane kunye nokuvelisa amaqondo obushushu aphezulu afunekayo ukunyibilikisa izinto ezikrwada.Ngenxa ye-conductivity ephezulu ye-thermal kunye nokunyanzeliswa kombane ophantsi, i-electrode yegraphite eyenziweyo iyakwazi ukumelana neemeko ezigqithiseleyo ngaphakathi kwesithando somlilo, okwenza kube yinto efanelekileyo yokukhetha kwesi sicelo.Ngaphaya koko, amandla abo omatshini akhethekileyo kunye nokuchasana nokothuka kwe-thermal kuqinisekisa ubomi obude, ngaloo ndlela kuncitshiswa ukugcinwa kunye neendleko zokutshintsha.
Ngaphandle kokwenziwa kwentsimbi, iielectrode ezenziweyo zegraphite zikwasetyenziswa kwimetallurgy engekhoyo, ngakumbi kwimveliso yealuminiyam.Ngexesha lenkqubo yokunyibilikisa, ezi electrode zisetyenziselwa ukubonelela amandla ayimfuneko okunciphisa i-aluminam kwi-electrolytic kwi-aluminiyam.Umthamo ophezulu ophetheyo wangoku kunye nokumelana nobushushu obugqwesileyo be-electrode yegraphite eyenziweyo kubenza bafaneleke ngokufanelekileyo kwesi sicelo, okwenza ukuba imveliso ye-aluminium esebenzayo kunye neyonga imali.
Ngaphezu koko, iielectrode ezenziweyo zegraphite zisetyenziswa kakhulu xa kusenziwa imichiza nezinto ezithile.Ngokomzekelo, baqeshwe kwimveliso yeiimveliso zegraphite, isinyithi se-silicon, kunye ne-phosphorus, phakathi kwabanye.I-conductivity ephezulu yombane kunye nokuzinza kwe-thermal yala ma-electrode kwenza kube yinto ekhethwayo kwiinkqubo ezibandakanya ukusabela kobushushu obuphezulu kunye nokuveliswa kobushushu obukhulu.Oku ke, kunegalelo ekuphuculweni kwemveliso kunye nomgangatho kwimveliso yeekhompawundi ezahlukeneyo zeekhemikhali kunye nemathiriyeli.
Ukongeza kwizicelo zabo ezahlukeneyo, i-electrode yegraphite eyenziweyo iyathandwa ngenxa yozinzo kunye neenzuzo zokusingqongileyo.Njengenxalenye ephambili kwi-steelmaking arc furnace steelmaking, ezi electrode zinegalelo ekusetyenzisweni kwakhona ngokufanelekileyo kwentsimbi ye-scrap, ngaloo ndlela inciphisa imfuno yezinto eziluhlaza kunye neempembelelo zokusingqongileyo ezinxulumene nokutsalwa kunye nokusebenza kwazo.Ngaphaya koko, ukusetyenziswa kwabo kwisinyithi esingenawo intsimbi kuxhasa ukuveliswa kwealuminiyam ekhaphukhaphu kunye ne-corrosion-resistant, enezicelo ezininzi kwimizi-mveliso yeemoto, i-aerospace, kunye neyokwakha, inegalelo kwizenzo ezizinzileyo kunye ne-eco-friendly.
Ukusetyenziswa kwe-electrode yegraphite eyenziweyoayiphelelanga kwiinkqubo ezinkulu zemizi-mveliso kodwa iphinda idlulele kuphando kunye nophuhliso kwinkalo ye-electrochemistry.Ezi electrode zisetyenziswa kuvavanyo lwaselabhoratri kunye nezifundo zokulinganisa ukulinganisa ukuphanda ukusabela kwe-electrochemical, electrocatalysis, kunye nezixhobo zokugcina amandla.Ukucoceka kwabo okuphezulu, ukufana, kunye neempawu ezilawulekayo zenza ukuba zibe lukhetho olufanelekileyo kwizicelo ezinjalo, ukuququzelela iziphumo ezichanekileyo nezithembekileyo kwiinzame ezahlukeneyo zophando lwe-electrochemical.
Ngaphaya koko, ukuguquguquka kweeelectrode ezenziweyo zegraphite zenza ukuba zisetyenziswe kwezinye izinto ezisetyenziswayo, njengezibane ze-arc zombane, izinto zokufudumeza, kunye nezixhobo zenyukliya.Kwizibane ze-arc zombane, ezi electrode zisetyenziselwa ukuvelisa ukukhanya okukhulu kwiinjongo ezikhethekileyo zoshishino kunye nesayensi, ngelixa kwizinto zokufudumeza ukuchasana, zibonelela ngokufudumeza okusebenzayo kwiinkqubo eziphezulu zokushisa.Ukongezelela, ukusetyenziswa kwazo kwizixhobo zenyukliya kubonisa amandla azo okumelana nemitha eyingozi kakhulu neemeko zobushushu, nto leyo ezenza zibe yinxalenye eyimfuneko ekuveliseni amandla enyukliya.
Iielectrode ezenziweyo zegraphite zidlala indima ebalulekileyo kwiinkqubo ezahlukeneyo zemizi-mveliso, ukusukela ekwenzeni intsimbi kunye nesinyithi esingenawo intsimbi ukuya kwimveliso yeekhemikhali kunye nemathiriyeli.Eyokwenziwaiimpawu ze-graphite electrode, kubandakanywa ukuqhutyelwa kwe-thermal ephezulu, amandla omatshini, kunye nokuchasana nokutshitshiswa kwe-thermal, kubenze babe lukhetho olufanelekileyo kwizicelo ezibandakanya ukushisa okuphezulu kunye neemfuno zamandla amakhulu.Ngaphaya koko, ukuzinza kwazo, iingenelo zokusingqongileyo, kunye nokuguquguquka kwazo ngakumbi kugxininisa ukubaluleka kwazo kwiinzame zale mihla zemizi-mveliso nezenzululwazi.Njengoko ukuqhubela phambili kwetekhnoloji kunye nokusetyenziswa okutsha kufunyanwa, i-electrode yegraphite eyenziweyo ikulungele ukuqhubeka nokuba negalelo kuphuhliso kunye nokuphucula iinkqubo ezahlukeneyo kumashishini ahlukeneyo.
