"Ua kūʻai ʻia ka mākeke electrode graphite honua ma 9.13 biliona kālā ʻAmelika i ka makahiki 2018 a ke manaʻo ʻia nei e hōʻea i 16.48 biliona kālā ʻAmelika e 2025, me ka nui o ka ulu ʻana o ka makahiki he 8.78% i ka wā wānana."
Me ka piʻi ʻana o ka hana kila a me ka ʻenehana o nā ʻenehana hou, ke hoʻomau nei ka koi no ka ʻenehana a me nā mea kūkulu hale, ʻo ia kekahi o nā mea koʻikoʻi e alakaʻi nei i ka ulu ʻana o ka mākeke graphite electrode honua.

ʻO nā electrodes graphite nā mea hoʻomehana i hoʻohana ʻia i nā kapuahi uila e hana i ke kila mai nā ʻōpala, nā kaʻa kahiko a me nā mea hana ʻē aʻe.Hāʻawi nā electrodes i ka wela i ke kila ʻōpala e hoʻoheheʻe iā ia e hana i ke kila hou.Hoʻohana nui ʻia nā umu ahi uila i nā ʻoihana hana kila a me ka alumini no ka mea maʻalahi lākou e hana.Hiki ke hōʻuluʻulu ʻia nā electrodes graphite i loko o nā cylinders no ka mea he ʻāpana lākou o ka uhi umu uila.Ke hele ka ikehu uila i hoʻolako ʻia i kēia mau electrodes graphite, ua hoʻokumu ʻia kahi arc uila ikaika, e hoʻoheheʻe i ke kila ʻōpala.E like me ka makemake wela a me ka nui o ka umu uila, hiki ke hoʻohana ʻia nā electrodes nui like ʻole.No ka hana ʻana i 1 ton o ke kila, ma kahi o 3 kg o nā electrodes graphite e koi ʻia.I ka hana ʻana i ke kila, hiki i ka graphite ke kū i nā wela kiʻekiʻe, no laila ke kiʻekiʻe ka wela o ka piko electrode ma kahi o 3000 degere Celsius.ʻO nā nila a me ka petroleum coke ka mea nui i hoʻohana ʻia e hana i nā electrodes graphite.He ʻeono mahina e hana ai i nā electrodes graphite, a laila hoʻohana ʻia kekahi mau kaʻina hana, me ka kuke ʻana a me ka hana hou ʻana, e hoʻololi i ka coke i graphite.ʻOi aku ka maʻalahi o ka hana ʻana i nā electrodes graphite ma mua o nā electrodes keleawe, a ʻoi aku ka wikiwiki o ka hana ʻana no ka mea ʻaʻole pono ia i nā kaʻina hana hou e like me ka wili lima.
ʻO ke kūkulu ʻana i ka mākeke graphite electrode, ka piʻi nui ʻana o ke koi no ke kila i ka aila a me ka ʻenehana a me nā ʻoihana automotive e manaʻo ʻia e hāpai i ka hoʻomohala ʻana o ka mākeke electrode graphite.ʻOi aku ma mua o 50% o ke kila honua i hana ʻia i hoʻohana ʻia i nā ʻoihana kūkulu a me nā ʻoihana.Aia ka hōʻike i nā mea hoʻokele, nā kaohi, nā manawa, a me nā ʻano hou i kōkua i ka ulu ʻana o ka mākeke i ka wā loiloi.Hoʻopili kikoʻī ka hōʻike i nā ʻano a me nā hoʻohana ʻana o ka māhele ʻāina.
ʻO ka graphite electrode kekahi o nā conductors, a he ʻāpana pono ʻole ia o ke kaʻina hana kila.Ma kēia kaʻina hana, hoʻoheheʻe ʻia ka hao ʻōpala i loko o ka umu uila a hana hou ʻia.Ua hoohehee maoli ka graphite electrode i loko o ka umu.He kiʻekiʻe ka hoʻoili wela o ka graphite, a he wela loa a pale i ka hopena.He haʻahaʻa kona kūpaʻa, ʻo ia hoʻi, hiki iā ia ke alakaʻi i nā kahawai nui e pono ai e hoʻoheheʻe i ka hao.Hoʻohana nui ʻia ka graphite electrode i ka umu uila arc (EAF) a me ka ladle furnace (LF) no ka hana kila, ferroalloy, silicon metal graphite electrode i hoʻohana ʻia i ka umu uila arc (EAF) a me ka ladle furnace (LF) no ka hana kila, hana ferroalloy, metala silika Ka hana ʻana a me ka hoʻoheheʻe ʻana
ʻO ka hōʻike o ka mākeke graphite electrode honua e uhi i nā mea pāʻani kaulana e like me GrafTech, Fangda Carbon China, SGL Carbon Germany, Showa Denko, Graphite India, HEG India, Tokai Carbon Japan, Nippon Carbon Japan, SEC Carbon Japan, etc. American GrafTech, Fangda Loaʻa iā Carbon China a me Graphite India ka nui o ka mana hana o 454,000 tons.
