550mm high ikon graphite lantarki
HP graphite lantarki an yi shi ne da coke na man fetur da coke coke, Yana da ikon ɗaukar nauyin halin yanzu 18-25A/cm2. An ƙera shi don yin babban ƙarfin wutar lantarki arc tanderun ƙarfe.
Hanyoyin ƙera ƙarfe na zamani sun haɗa da ƙera karfe da injin tanderun lantarki. Bambanci mafi mahimmanci tsakanin hanyar yin ƙarfe na tanderun lantarki da kuma hanyar ƙera karfe shine hanyar tanderun lantarki na yin amfani da makamashin lantarki azaman tushen zafi, kuma hanyar ƙera ƙarfe ta wutar lantarki ita ce mafi yawan amfani da ita.
Aikin ƙarfe na EAF yana dogara ne akan baka na wutar lantarki da ke fitarwa tsakanin lantarki da cajin, wanda ke canza makamashin lantarki zuwa makamashi mai zafi a cikin hasken baka, kuma yana amfani da aikin radiation da baka don zafi da narkar da karfe da slag don narke. karfe da gami na daban-daban abun da ke ciki.

Ƙirƙirar lantarki na graphite
1.Petroleum coke baƙar fata ne kuma mai laushi, carbon shine babban abun ciki, kuma abun cikin ash yana da ƙasa sosai, gabaɗaya ƙasa da 0.5%.
Ana iya raba coke na man fetur zuwa nau'i biyu na danyen coke da calcined coke bisa ga zafin maganin zafi. Tsohon yana ƙunshe da adadi mai yawa na al'amura masu canzawa kuma yana da ƙananan ƙarfin inji. Ana samun coke calcined ta hanyar ƙididdige ɗanyen coke.
Ana iya raba coke na man fetur zuwa babban sulfur coke (tare da abun ciki na sulfur sama da 1.5%), matsakaicin sulfur coke (tare da abun ciki na sulfur 0.5% -1.5%), da ƙananan sulfur coke (tare da abun ciki na sulfur a ƙasa 0.5%) bisa ga matakin sulfur. Na'urorin lantarki na graphite da sauran samfuran graphite na wucin gadi ana samarwa gabaɗaya ta amfani da ƙaramin coke na sulfur.
2.Needle coke ne wani irin high quality-coke tare da fili fiber texture, musamman low thermal fadada coefficient da sauki graphitization. Saboda haka, coke allura shine mabuɗin albarkatun ƙasa don kera manyan lantarki ko ultra-high-power graphite electrodes wanda aka nuna tare da ƙananan juriya, ƙananan haɓakar haɓakar thermal, da kuma kyakkyawan juriya na thermal.
3.Coal pitch yana daya daga cikin manyan samfurori na kwalta bayan aiki mai zurfi. Cakuda ne na nau'ikan hydrocarbons da yawa. Ana amfani da farar kwal azaman abin ɗaurewa da abin da ba a ciki. Ayyukansa yana da babban tasiri akan ingancin lantarki na graphite.
