Graphite electrode bụ akụkụ dị mkpa nke EAFsteelmaking, mana ọ bụ naanị maka obere akụkụ nke ọnụ ahịa nchara.Ọ na-ewe kilogram 2 nke graphite electrode iji mepụta ton nke ígwè.
Gịnị kpatara eji graphite electrodes?
Graphite electrode bụ isi kpo oku eduzi oyiyi akwa nke aak oku.EAF bụ usoro ịgbaze scrap site na ụgbọ ala ochie ma ọ bụ ngwa ụlọ iji mepụta ígwè ọhụrụ.
Ọnụ ego e ji arụ ọkụ ọkụ eletrik dị ala karịa nke ọkụ mgbawa ọdịnala.Ọkụ mgbawa ọdịnala na-eme ígwè sitere na ọla igwe ma na-eji coking coal dị ka mmanụ ụgbọala.Otú ọ dị, ọnụ ahịa nchara dị elu na mmetọ gburugburu ebe obibi dị njọ.Otú ọ dị, EAF na-eji ígwè na ọkụ eletrik, nke na-adịghị emetụta gburugburu ebe obibi.
A na-eji electrode graphite chịkọta electrode na mkpuchi ọkụ ahụ n'ozuzu ya, na graphite electrode nwere ike ịrụ ọrụ elu na ala.Ihe dị ugbu a na-agafe na electrode, na-akpụ arc na-ekpo ọkụ nke na-agbaze nchara nchara.The electrodes nwere ike ruo 800mm (2.5ft) na dayameta na ruo 2800mm (9ft) n'ogologo.Oke kachasị dị ihe karịrị metrik tọn abụọ.
Oriri eletrọd graphite
Ọ na-ewe kilogram 2 (paụnd 4.4) nke electrodes graphite iji mepụta ton nke ígwè.
Graphite electrode okpomọkụ
N'ọnụ nke electrode ga-eru 3,000 degrees Celsius, ọkara nke elu okpomọkụ nke anyanwụ.Emere electrode nke graphite, n'ihi na ọ bụ naanị graphite nwere ike iguzogide oke okpomọkụ dị otú ahụ.

Graphite electrode na-eri ọkụ eletrik
Usoro a chọrọ ọkụ eletrik zuru oke iji mee ka obodo mmadụ 100,000 nwee ike.N'ime ọkụ ọkụ eletrik ọgbara ọhụrụ, agbaze nke ọ bụla na-ewe nkeji iri itoolu ma nwee ike imepụta tọn 150 nke ígwè, nke zuru ezu iji rụọ ụgbọ ala 125.
Akụrụngwa
Coke agịga bụ isi akụrụngwa maka electrodes, nke na-ewe ihe dị ka ọnwa atọ ruo ọnwa isii iji mepụta.Usoro a na-agụnye ịsa anụ na ịmụ nwa iji gbanwee coke ka ọ bụrụ graphite, onye nrụpụta kwuru.
Enwere coke agịga mmanụ ala na coal coke agịga, enwere ike iji ha abụọ mepụta electrodes graphite."Pet coke" bụ ihe sitere na usoro nhazi mmanụ ala, ebe a na-emepụta coal-to-coke site na coal tar nke na-eme n'oge a na-emepụta coke.
