Usoro nrụpụta
Graphite electrode bụ tumadi mere petroleum coke na agịga coke, weere na coal pitch, na-na usoro nke calcinations, igwakorita, akpụ, mmiri, graphitizing na machining, n'ikpeazụ ịbụ ngwaahịa. Nke a bụ ụfọdụ nkọwa maka ụfọdụ usoro mmepụta:
Ịgwakọta: Na-akpali ma na-agwakọta ụfọdụ ihe nke carbon particles na ntụ ntụ na ụfọdụ ihe nkedo na ụfọdụ okpomọkụ, a na-akpọ usoro a igwakorita.
Ọrụ nke igwakorita
① Gwakọta ụdị ngwaọrụ niile n'otu n'otu, ma n'otu oge ahụ na-eme ka carbon siri ike nke nha nha dị iche iche na-agwakọta ma jupụta, ma melite njupụta nke ngwakọta;
② Mgbe agbakwunyere coal asphalt, kpokọta ihe niile ọnụ.
③Ụfọdụ oghere coal na-abanye n'ime oghere dị n'ime, nke na-eme ka njupụta na nchikota nke mado ahụ dịkwuo mma.
Ịmepụta: A na-ebupụ pasta carbon a gwakọtara agwakọta n'ime ahụ akwụkwọ ndụ akwụkwọ ndụ (ma ọ bụ ngwaahịa akwụkwọ ndụ akwụkwọ ndụ) nwere ụfọdụ udi, nha, njupụta na ike n'ime ngwa ịkpụzi. Ihe nkedo ahụ nwere nrụrụ plastik n'okpuru ike mpụga.
Nri a na-akpọkwa achịcha, Ọ bụ ọgwụgwọ dị elu nke okpomọkụ, na-eme ka coal pitch carbonized na coke kpụrụ, nke na-eme ka carbonaceous aggregates na ntụ ntụ na-ejikọta ya na ike ọrụ dị elu, nkwụsị dị ala, nkwụsi ike dị mma na nkwụsi ike kemịkalụ.
Nri nke abụọ bụ ịsa otu oge ọzọ, na-eme ka olulu na-abanye n'ime ya bụ carbonized. Electrodes (ụdị niile ma e wezụga RP) na nipples nke chọrọ nnukwu njupụta dị elu ka achọrọ ka a sie ya nke abụọ, na nipples atọ-mikpu anọ-achicha ma ọ bụ abụọ-mikpu atọ-achicha.
