400 UHP graphite lantarki
Ana amfani da na'urorin lantarki na graphite musamman a aikin ƙera ƙarfe. Ƙarfe yana narkewa a cikin tanderun baka na lantarki kuma ana sake yin fa'ida. A matsayin nau'in jagora, su ne muhimmin sashi a cikin irin wannan
UHP graphite lantarki ne yafi sanya sama da high quality-coke allura, kuma yadu amfani a matsananci high ikon wutar lantarki baka tanderu.It ne iya ɗaukar halin yanzu yawa fiye da 25A/cm2

Tsarin sarrafawa
Graphite electrode ne yafi sanya na man fetur coke da allura coke, gauraye da kwal farar, samun ta hanyoyin da calcinations, kneading, forming, yin burodi, graphitizing da machining, a karshe ya zama samfurori. Anan akwai wasu bayanai don wasu tsarin samarwa:
Kneading: Yin motsawa da haɗuwa da wani adadin ƙwayar carbon da foda tare da wani adadin abin ɗaure a wani yanayin zafi, wannan tsari shine ake kira kneading.

②Bayan ƙara kwalta kwal, sai a haɗa duk kayan da kyau tare.
③Wasu filayen kwal suna shiga cikin ɓangarorin ciki, wanda ke ƙara haɓaka ɗimbin yawa da mannewa na manna.
Ƙirƙirar: Manna carbon ɗin da aka kneaded ana fitar da shi cikin koren jiki (ko samfurin kore) tare da takamaiman siffa, girman, yawa da ƙarfi a cikin kayan gyare-gyare. Manna yana da nakasar filastik a ƙarƙashin ƙarfin waje.
