Iielectrode zegraphiteidlala indima ebalulekileyo kushishino lwangoku, ngakumbi kwinkalo yokwenza intsimbi.Ngaphandle kwezi zixhobo zibalulekileyo, yonke inkqubo yokuvelisa intsimbi yayiza kumisa ukugaya.Ngenxa yoko, imfuno yabavelisi be-electrode ekumgangatho ophezulu iye yanda kakhulu kwiminyaka yakutshanje.
Iielectrode zegraphite zisetyenziswa ikakhulu kwiziko lombane (EAFs) kunye neeleyile zokuhambisa umbane wokunyibilikisa isinyithi esilahliweyo okanye ezinye izinto ezikrwada.Ezi electrode zinika amandla ombane ayimfuneko ukuze kuveliswe ubushushu obukhulu obufunekayo ukuze kunyibilike isinyithi kwaye kuqalise ukusabela kweekhemikhali ukususa ubumdaka kwintsimbi etyhidiweyo.Ngomsebenzi obalulekileyo onjalo, ukhetho lomenzi we-graphite electrode luba lubalulekileyo kubavelisi bentsimbi.
Iinkqubo yokuvelisa i-graphite electrodeiqala ngokukhethwa ngononophelo kwemathiriyeli ekrwada, ikakhulu i-petroleum coke kunye nenaliti yecoke.Ezi zixhobo zifudumeza ngamandla ukuze zisuse ukungcola, okukhokelela kwimveliso ecocekileyo ye-carbonaceous.I-coke ecociweyo ke ixutywe netha yetha yamalahle kwaye ibunjwe kwimilo ye-electrode efunwayo kusetyenziswa inkqubo yokubumba.Emva koko, imveliso egqityiweyo iyabhakwa kumaqondo obushushu aphezulu kakhulu ukuyiguqula ibe yimeko eqinileyo yekhabhoni.Imijikelo emininzi yomatshini kunye nokutshekishwa okungaphezulu komgangatho kuyenziwa ukuze kuqinisekiswe ukuba ii-electrode ziyahlangabezana nemigaqo efunekayo.
Nangona kunjalo, ukuba ngumenzi we-electrode yegraphite ayikho ngaphandle kwemingeni yayo.Okokuqala, ishishini lijongene neenkxalabo ezinkulu zokusingqongileyo ngenxa yemeko yekhabhoni yenkqubo yemveliso.Ukuqaphela oku, abavelisi baye batyala imali kuphando kunye nophuhliso lokunciphisa i-carbon footprint kunye nokunciphisa ukuveliswa kwenkunkuma.Ukongeza, ubukho kunye neendleko zemathiriyeli ekrwada ekumgangatho ophezulu zizinto ezibalulekileyo ezichaphazela inkqubo yokuvelisa.Nakuphi na ukuphazamiseka kwikhonkco lokubonelela ngempahla ekrwada kunokuba nefuthe elibi kwimveliso yee-electrode zegraphite.
Ngaphandle kweshishini le-steelmaking, i-graphite electrode iphinda ifumane ukusetyenziswa kwamanye amacandelo.Umzekelo, zizinto eziyimfuneko kwiziko zombane ze-arc ezisetyenziselwa ukunyibilikisa i-aluminiyam ye-scrap.Imfuno ye-aluminiyam iyanda ngokuqhubekayo ngenxa yeempawu zayo ezikhaphukhaphu kunye nokusetyenziswa ngokubanzi kumacandelo ezothutho kunye nokwakha.Abavelisi be-electrode yegraphite badlala indima ebalulekileyo ekuqinisekiseni unikezelo oluzinzileyo lwee-electrode ukuhlangabezana nale mfuno ikhulayo.
Ngapha koko, ii-electrode zegraphite zibaluleke kakhulu kwimveliso yentsimbi yesilicon kunye nezinye ialloys esekwe kwisilicon.I-silicon licandelo elibalulekileyo ekwenziweni kweemveliso ezahlukeneyo ze-elektroniki, iiphaneli zelanga, kunye nezixhobo zonyango.Njengoko itekhnoloji ihambela phambili kunye nemfuno yezi mveliso isanda, ukubaluleka kwabavelisi abathembekileyo begraphite electrode kuya kubonakala ngakumbi.
Ukuququmbela,abavelisi be-electrode yegraphitebangabadlali ababalulekileyo kwicandelo lezoshishino, kunye neemveliso zabo ezixhasa iinkqubo ezahlukeneyo ezibalulekileyo.Ubuchwephesha babo ekuveliseni i-electrode ekumgangatho ophezulu iqinisekisa ukusebenza kakuhle kwezitofu zombane ze-arc kunye neengqayi zeeladi.Ngaphandle kwemiceli mngeni enxulumene nefuthe lokusingqongileyo kunye nokufumaneka kwezixhobo ekrwada, ishishini liyaqhubeka nokuvela, lizama ukwenza izinto ezizinzileyo kunye nobuchwepheshe obutsha.Njengoko imfuno yentsimbi, i-aluminium, kunye ne-silicon-based alloys iqhubeka nokunyuka, iminikelo yabavelisi be-electrode yegraphite ibalulekile ekukhuleni nasekuphuhliseni la macandelo.
