I-electrodes yegraphite zizinto eziphambili kule nkqubo njengoko zisebenza njengezinto eziqhubayo ezivumela ukuba umbane uqhubele kwizinto ezinyibilikayo.

Kutheni ii-electrode zegraphite ziye zafumana ukuthandwa kwii-EAFs kwaye ziphonononga iimpawu zazo ezikhethekileyo ezibenza bahluke kwezinye iindlela.

I-electrode yegraphite yenziwe ngezinto ezicocekileyo zegraphite, ezibonelela ngokugqwesileyo kombane, ukuxhathisa kwe-thermal, kunye namandla omatshini wokumelana neemeko ezifunekayo zesithando sombane se-arc. Ezi electrode zidlala indima ebalulekileyo kwinkqubo yokwenza intsimbi ngokuqhuba umbane kunye nokuvelisa ubushushu obukhulu obuyimfuneko ekunyibilikiseni isinyithi esilahliweyo kunye nokusulungekiswa kwentsimbi.

Mna:Ii-electrode zegraphite zinezinga eliphezulu lokuqhuba kombane

Esinye sezizathu eziphambili zokuba kutheni i-graphite electrode ikhethwa kwii-EAFsigraphite electrode conductivity yombanekakhulu. I-graphite yaziwa ngokuba yi-conductivity ekhethekileyo, evumela ukuhanjiswa kombane ngokufanelekileyo kwizinto ezihlawuliswayo eziko. Le conductivity ephezulu iqinisekisa ukufudumeza ngokukhawuleza kunye okufanayo kwentsimbi ye-scrap, ekhokelela ekuphuculeni ukusebenza kakuhle kwamandla kunye nokunciphisa ukusetyenziswa kwamandla.

II:Ii-electrode zegraphite zibonelela ngokumelana nobushushu obubalaseleyo

Ukongeza kwi-conductivity yabo yombane, ii-electrode zegraphite zikwanazo nokumelana nobushushu obumangalisayo. Ukushisa okukhulu okwenziwa ngexesha lenkqubo yokwenza insimbi kunokubangela ukugqoka okubalulekileyo kunye nokukrazula kwi-electrodes. Ulwakhiwo olulodwa lwegraphite kunyeiimpawu ezishushu zegraphiteiyenze ikwazi ukumelana namaqondo obushushu agqithisileyo ngaphandle kokufumana inguquko okanye ukuthotywa. Olu phawu alugcini nje ukwandisa ubomi benkonzo yee-electrodes kodwa lunceda nokugcina iimeko ezizinzileyo zesithando somlilo kunye nokuphucula imveliso jikelele.

III:Ii-electrode zegraphite zingamandla aphezulu oomatshini

Amandla omatshini lolunye uphawu olubalulekileyo lweeelectrode zegraphite. Ubume obufunayo ngaphakathi kwesithando sombane se-arc, kubandakanywa ukunyakaza okuqhubekayo kunye noxinzelelo lomatshini olubangelwa ukutshaja kwesinyithi esilahliweyo kunye nokubeka i-electrode, kufuna i-electrodes enamandla akhethekileyo kunye nokuzinza. I-electrode ye-graphite ibonelela ngengqibelelo yesakhiwo esiyimfuneko ukuze simelane nezi meko ezinzima, ukuqinisekisa ukusebenza okuthembekileyo kunye nokungaphazamiseki ngexesha le-steelmaking process.

IV:Ii-electrode zegraphite zibonelela ngeendleko ezifanelekileyo

Iielectrode zegraphite nazo zibonelela ngenzuzo ngokweendleko-zokusebenza. Xa kuthelekiswa nezinye izinto ze-electrode ezisetyenziswa ngokuqhelekileyo kwii-EAFs, ezifana nobhedu, i-graphite electrode inoqoqosho ngakumbi. Ii-electrode zobhedu zibiza kakhulu ngenxa yexabiso eliphezulu lezinto eziluhlaza kunye neenkqubo zokuvelisa eziyinkimbinkimbi. Ngakolunye uhlangothi, i-electrode yegraphite inokuveliswa ngexabiso eliphantsi, inika isisombululo esinexabiso eliphantsi kubavelisi bentsimbi.

V:I-electrode zegraphite zibonelela ngezinto ezahlukeneyo

Ukuguquguquka kwee-electrode zegraphite kunegalelo ngakumbi ekuthandeni kwabo kwii-arc zombane zombane. Ezi electrode zingasetyenziselwa zombini i-alternating current (AC) kunye ne-direct current (DC) ye-EAFs, inikezela ukuguquguquka kubenzi bentsimbi ngokuxhomekeke kwiimfuno zabo zokusebenza ezithile. Oku kuguquguqukayo, kudibene nokusebenza kwabo okuphezulu, kubeka i-electrode yegraphite njengokhetho oluthembekileyo noluguquguqukayo kwiinkqubo ezahlukeneyo zentsimbi.

VI:Ii-electrode zegraphite zibonelela ngeenzuzo zokusingqongileyo

Ngapha koko, ii-electrode zegraphite zibonelela ngeenzuzo zokusingqongileyo. Ukusetyenziswa kwei-electrode yegraphite kwii-arc zombane zombanekunciphisa ukukhutshwa kweegesi ze-greenhouse xa kuthelekiswa neendlela eziqhelekileyo zokwenza intsimbi, ezifana neziko lokuqhushumba. Ukusebenza kwamandla kunye nokunciphisa ukusetyenziswa kombane okuphunyeziweyo ngokusetyenziswa kwe-electrode yegraphite negalelo ekunciphiseni i-carbon footprint yeshishini lensimbi, okwenza kube yinto ezinzileyo kunye nokusingqongileyo.

Ukuqukumbela, i-electrode yegraphite iye yavela njengokhetho olukhethiweyo kwii-arc zombane zombane ngenxa yeempawu zabo ezibalaseleyo kunye nokusebenza. Ukudityaniswa kwe-conductivity ephezulu yombane, ukuxhathisa kwe-thermal, kunye namandla omatshini kwenza i-graphite electrode ilungele ukumelana neemeko ezinzima zenkqubo yokwenza intsimbi. Ngaphezu koko, ukusebenza kakuhle kweendleko, ukuguquguquka, kunye neenzuzo zokusingqongileyo ziphucula ngakumbi umdla wabo kwishishini. Njengoko ishishini lentsimbi liqhubeka nokuguquka kunye nokwamkela izenzo ezizinzileyo, i-electrode yegraphite ngokungathandabuzekiyo iya kuhlala iyinxalenye ebalulekileyo kwimveliso yentsimbi.
