Don nau'ikan nau'ikan carbon da samfuran lantarki na graphite, gwargwadon amfaninsu daban-daban, akwai buƙatun amfani na musamman da alamun inganci.Lokacin yin la'akari da irin nau'in kayan da ya kamata a yi amfani da su don wani samfurin, ya kamata mu fara nazarin yadda za mu cika waɗannan buƙatu na musamman da kuma alamun inganci.
(1) Zaɓin albarkatun ƙasa don gudanar da lantarki na graphite da aka yi amfani da su a cikin tsarin lantarki kamar EAF ƙarfe.
The conductive graphite lantarki amfani da electrometallurgical tsari kamar EAF steelmaking dole ne yana da kyau conductivity, dace inji ƙarfi, mai kyau juriya quenching da dumama a high zazzabi, lalata juriya da kuma low kazanta abun ciki.
① High quality graphite lantarki da aka samar daga man fetur coke, farar coke da sauran low ash albarkatun kasa.Duk da haka, samar da graphite lantarki bukatar karin kayan aiki, dogon tsari kwarara da kuma rikitarwa fasaha, da kuma ikon amfani da 1 t graphite lantarki ne 6000 ~ 7000 kW · H.
② Ana amfani da coke mai inganci na anthracite ko ƙarfe a matsayin ɗanyen abu don samar da wutar lantarki.Samar da lantarki na carbon ba ya buƙatar kayan aikin graphitization, kuma sauran hanyoyin samarwa iri ɗaya ne da samar da lantarki mai graphite.Ƙarƙashin wutar lantarki na carbon ya fi na graphite lantarki muni.Resistivity na carbon electrode gabaɗaya sau 2-3 ya fi na graphite lantarki girma.Abubuwan da ke cikin toka sun bambanta da ingancin kayan aiki, wanda shine kusan 10%.Amma bayan tsaftacewa na musamman, ana iya rage ash abun ciki na anthracite zuwa ƙasa da 5%.Ana iya rage abun cikin tokar samfurin zuwa kusan 1.0% idan samfurin ya ƙara jadawali.Ana iya amfani da na'urar lantarki don narkewar ƙarfe na EAF na gama gari da ferroalloy
③ Yin amfani da graphite na halitta azaman albarkatun ƙasa, an samar da lantarki graphite na halitta.Za'a iya amfani da graphite na halitta kawai bayan an zaɓi a hankali kuma an rage abun cikin ash.Resistivity na halitta graphite lantarki ne game da ninki biyu na graphitized lantarki.Amma ƙarfin injin yana da ɗan ƙaramin ƙarfi, mai sauƙin karya lokacin amfani.A cikin yankin da ke da yawan samar da graphite na halitta, ana iya samar da na'urar lantarki ta graphite don samar da ƙaramin EAF don narkar da ƙarfe na EAF gama gari.Lokacin amfani da graphite na halitta don samar da wutar lantarki, kayan aiki da fasaha suna da sauƙin warwarewa da ƙwarewa.
④ Ana amfani da na'urar graphite don samar da wutar lantarki da aka sabunta (ko graphitized karyayyen lantarki) ta hanyar murƙushewa da niƙa na yanke tarkace ko samfuran sharar gida.Abubuwan da ke cikin toka na samfurin ba su da yawa (kimanin 1%), kuma halayen sa ya fi na graphitized lantarki muni.Ƙarfin ƙarfinsa yana kusan sau 1.5 na na lantarki mai graphitized, amma tasirin aikace-aikacensa ya fi na graphite electrode na halitta.Ko da yake yana da sauƙi don ƙwarewar fasaha da kayan aiki don samar da wutar lantarki mai sabuntawa, tushen albarkatun kayan aiki na graphitization yana da iyaka, don haka wannan hanya ba shine jagorancin ci gaba ba.
