Mmepe teknụzụ nwere akụkọ ihe mere eme nke ihe dị ka afọ 100 na nchara EAF, n'agbanyeghị na ụzọ ndị ọzọ na-eche ihe ịma aka na ịsọ mpi na-eche ihu mgbe niile, ọkachasị nsonaazụ ikuku oxygen dị elu, mana akụkụ nke mmepụta nchara nke EAF steelmaking n'ụwa ka na-abawanye kwa afọ. Na mmalite 1990s, ígwè nke EAF mepụtara n'ụwa bụ 1/3 nke ngụkọta nchara. Na mba ụfọdụ, EAF bụ teknụzụ na-eme nchara n'ụfọdụ mba, na nha nchara nke EAF na-agbaze bụ 70% dị elu karịa nke ahụ na Italy.

N'afọ 1980, ebe niile na mmepụta ígwè EAF na nkedo na-aga n'ihu, wee jiri nwayọọ nwayọọ mepụta usoro mmepụta ike nke ọkụ ọkụ ọkụ eletrik na-agbaze ihe na-eme ka ọ bụrụ ihe na-aga n'ihu na-atụgharị na-aga n'ihu, a na-eji arc ọkụ eme ihe maka ngwa ngwa ngwa ngwa ngwa ngwa dị ka ihe eji eme ígwè. na enweghị nguzozi ugbu a na mmetụta siri ike na grid ike na nyocha nke DC arc oven, ma tinye n'ime ngwa mmepụta ihe na narị afọ mbụ.n'etiti 1990s, DC arc oku na-eji nanị 1 mgbọrọgwụ nke graphite electrode ka ọtụtụ ebe n'ụwa na 90s (2 na ụfọdụ graphite electrode DC arc ọkụ).

Ukwuu ibelata oriri nke graphite electrodes bụ kasị ukwuu uru nke DC arc ọkụ, tupu ọgwụgwụ nke 1970s, AC arc ọkụ kwa ton nke ígwè oriri nke graphite electrode na 5 ~ 8kg, graphite electrode akwụ ụgwọ maka 10% nke ngụkọta na-eri nke ígwè na 15%, ọ bụ ezie na e a ọnụ ọgụgụ nke jikoro, ma ọ bụ electrode oriri na-eri 6. gụrụ 7% 10%, ojiji nke ike dị elu na ultra ike steelmaking usoro, electrode yak na-ebelata ka 2 ~ 3k.g / T ígwè, DC arc ọkụ nke na-eji naanị 1 graphite electrode, graphite electrode oriri nwere ike ibelata 1.5kg / T ígwè n'okpuru.

Ma tiori na omume na-egosi na otu oriri nke graphite electrode nwere ike ibelata site 40% ka 60% ma e jiri ya tụnyere AC arc ọkụ.
