I nā makahiki i hala iho nei, ka honuagraphite electrodeUa ulu mau ka mākeke e ka noi mai nā ʻoihana like ʻole.ʻO kekahi o nā ʻoihana nui e koi ana i ka ʻoihana kila.ʻO nā electrodes graphitehe ʻāpana koʻikoʻi o ke kaʻina hana kila a hoʻohana ʻia i ka hana kila arc furnace (EAF).

Ke ulu mau nei ka lawe ʻana mai o nā electrodes graphite i nā makahiki i hala iho nei ma muli o ka ulu ʻana o ke koi kila i nā ʻoihana e kū mai ana e like me India, Brazil, Egypt, Iran, Turkey, a me Thailand.Ke hoʻonui nei kēia mau ʻoihana e ulu nei i kā lākou mana hana kila, e alakaʻi ana i ka piʻi ʻana o ka noi no nā electrodes graphite.

Ua puka mai ʻo India ma ke ʻano he mea kūʻai nui i nā electrodes graphite, me ka ʻāina e lawe mai ana ma mua o 30% o ka nui o ka noi honua.Me ka manaʻo o ke aupuni o India e hoʻonui i ka mana hana kila o ka ʻāina i 300 miliona tonnes e 2023, manaʻo ʻia e hoʻonui hou ʻia ka noi no nā electrodes graphite.

ʻO kekahi hoʻokele waiwai ʻē aʻe, ʻo Brazil, ʻo ia ka ʻeiwa o ka mea hana kila nui loa ma ka honua, ke hoʻopukapuka nui nei i kāna ʻoihana kila.E like me India, ke ulu mau nei ka noi o Brazil no nā electrodes graphite, me ka ʻāina e lawe mai ana ma mua o 10% o ka noi honua. 

Ke piʻi mau nei ka lawe ʻana mai o nā electrodes graphite mai ʻAigupita, Kelemānia, Turkey, Thailand a me nā ʻāina ʻē aʻe.Ke hoʻolilo nei kēia mau ʻāina i kā lākou mana hana kila, e alakaʻi ana i ka piʻi ʻana o ka noi no nā electrodes graphite.

Eia kekahi, ke kaulana nei nā electrodes graphite ultra-high power (UHP) i waena o nā mea hana kila ma muli o kā lākou hana kiʻekiʻe a ʻoi aku ka ikaika o ka ikehu i hoʻohālikelike ʻia me nā electrodes graphite EAF maʻamau.Manaʻo ʻia nā electrodes graphite maʻemaʻe ultra-kiʻekiʻe no ka hapa nui o ka nui o ka noi graphite electrode i ka mākeke honua.

I ka hōʻuluʻulu ʻana, ke ulu nei ka mākeke electrode graphite honua i nā makahiki i hala iho nei, i alakaʻi ʻia e ka noi mai nā ʻoihana e kū mai ana e like me India, Brazil, Egypt, Iran, Turkey, a me Thailand.ʻO ka noi no nā electrodes graphite e manaʻo wale ʻia e hoʻonui i nā makahiki e hiki mai ana me ka hoʻonui ʻana i nā hoʻopukapuka ma ka ʻoihana kila a me ka neʻe ʻana i nā electrodes graphite UHP.
