Usoro mmepụta nke Graphite Electrode
Graphite electrode bụ ụdị elu okpomọkụ na-eguzogide graphite conductive ihe na-emepụta site na iji mmanụ ala coke, agịga coke dị ka mkpokọta, coal asphalt dị ka ihe nkedo, mgbe a usoro nke usoro dị ka ịgwakọta, ịkpụzi, rie nri, itinye, graphitization na n'ibu nhazi.
Isi mmepụta usoro nke graphite electrode bụ ndị a:
(1) Calcination.Petroleum coke ma ọ bụ asphalt coke kwesịrị ka a forged, na calcination okpomọkụ kwesịrị iru 1300 ℃, ka n'ụzọ zuru ezu wepụ agbanwe agbanwe ọdịnaya dị na carbon akụrụngwa, na melite ezi njupụta, n'ibu ike na eletriki conductivity nke coke.
(2) ihichapu, nyocha, na ihe eji eme ihe.A na-agbajikwa akụrụngwa carbon nke calcined ma na-ekpuchi ya n'ime ihe nchịkọta nke nha a kapịrị ọnụ, a na-akụtu akụkụ nke coke ka ọ bụrụ ntụ ntụ dị mma, na ngwakọta akọrọ na-etinye uche dịka usoro ahụ si dị.
(3) Ngwakọta.Na steeti kpo oku, a na-agwakọta ngwakọta akọrọ nke quantitative nke ihe dị iche iche na ihe nkedo quantitative, gwakọtara ma gwakọta ya iji mee ka pasta plastik mee ihe.
(4) ịkpụzi, n'okpuru omume nke mpụga mgbali (extrusion akpụ) ma ọ bụ n'okpuru omume nke elu ugboro vibration (vibration akpụ) pịa mado n'ime a ụfọdụ udi na elu njupụta nke raw electrode (billet).
(5) Ime achịcha.A na-etinye electrode raw n'ime ọkụ ọkụ pụrụ iche, a na-ejukwa ntụ ntụ coke metallurgical ma kpuchie ya na electrode raw.Na elu okpomọkụ nke bonding gị n'ụlọnga ihe dị ka 1250 ℃, a na-amịpụta carbon electrode.
(6) Adịghị ọcha.Iji meziwanye njupụta na ike n'ibu nke ngwaahịa electrode, a na-ebunye electrode na-eri nri n'ime akụrụngwa voltaji dị elu, a na-agbanyekwa asphalt mmiri mmiri n'ime oghere ikuku nke electrode.Mgbe imikpuchara ya, ekwesịrị ịme nri ahụ otu ugboro.Dị ka arụmọrụ chọrọ nke ngwaahịa ahụ, mgbe ụfọdụ a ga-emeghachi impregnation na nri nke abụọ ugboro 23.
(7) graphitization.A na-ebunye carbon electrode esiri esi n'ime ọkụ graphitization, kpuchie ya na ihe mkpuchi.Site na iji kpo oku usoro nke kpọmkwem electrification na-emepụta elu okpomọkụ, na carbon electrode na-converted n'ime graphite electrode na graphite crystal Ọdịdị na elu okpomọkụ nke 2200 ~ 3000 ℃.
(8) igwe.Dị ka ojiji chọrọ, graphite electrode oghere n'elu mbịne, flat ọgwụgwụ elu na ịghasa oghere maka njikọ njikọ, na nkwonkwo maka njikọ.
(9) A ga-akwakọba electrode graphite nke ọma mgbe ọ gafechara nyocha ma zigara onye ọrụ.
