550mm elu ike graphite electrode
HP graphite electrode bụ nke mmanụ ala coke na agịga coke, Ọ bụ ike na-ebu ugbu a njupụta 18-25A/cm2. Emebere ya maka ime ọkụ eletrik dị elu maka ime igwe.
Ụzọ nchara ọgbara ọhụrụ gụnyere nchara ngbanwe na nchara ọkụ eletrik. Ọdịiche kachasị dị n'etiti usoro nchara ọkụ eletrik na usoro ntugharị igwe bụ na igwe ọkụ ọkụ eletrik na-eji ike eletrik dị ka isi iyi ọkụ, yana usoro nchara ọkụ eletrik ka a na-ejikarị eme ihe.
EAF nchara na-adabere na arc eletrik na-emepụta site na mwepu n'etiti electrode na ụgwọ ahụ, nke na-agbanwe ike eletrik ka ọ bụrụ ike ọkụ na ọkụ arc, ma na-eji ihe kpọmkwem nke radieshon na arc na-ekpo ọkụ ma gbazee ígwè na slag iji gbazee. ígwè na alloys nke dị iche iche mejupụtara.

Ihe mejupụtara electrode graphite
1.Petroleum coke bụ nwa na porous, carbon bụ isi mejupụtara, na ash ọdịnaya dị nnọọ ala, n'ozuzu n'okpuru 0,5%.
Enwere ike kewaa coke mmanụ ala ụzọ abụọ nke raw coke na calcined coke dị ka okpomọkụ ọgwụgwọ okpomọkụ si dị. Nke mbụ nwere nnukwu ihe na-agbanwe agbanwe ma nwee ike ọrụ dị ala. A na-enweta coke calcined site n'ịgbakọta koke raw.
Enwere ike kewaa coke mmanụ n'ime nnukwu sọlfọ coke (nke nwere sọlfọ ọdịnaya karịa 1.5%), sọlfọ coke na-ajụkarị (nke nwere sọlfọ 0.5% -1.5%) na obere sọlfọ coke (ya na sọlfọ ọdịnaya n'okpuru 0,5%) dị ka sọlfọ larịị. A na-emepụta electrodes graphite na ngwaahịa graphite ndị ọzọ site na iji obere sọlfọ coke.
2.Needle coke bụ ụdị coke dị elu nke nwere udidi eriri doro anya, karịsịa ọnụọgụ mgbasawanye ọkụ dị ala na mfe graphitization. Ya mere, coke agịga bụ isi akụrụngwa maka imepụta ike dị elu ma ọ bụ ultra-high graphite electrodes nke nwere obere resistivity, obere ọnụọgụ mgbasawanye ọkụ, yana ezigbo nguzogide ujo.
3.Coal pitch bụ otu n'ime isi ngwaahịa nke coal tar mgbe nhazi miri emi. Ọ bụ ngwakọta nke otutu hydrocarbons. A na-eji ụda coal eme ihe dị ka ihe eji ejikọta na ihe na-eme ihe. Ọrụ ya nwere mmetụta dị ukwuu n'ịdị mma nke electrodes graphite.
