ʻO nā electrodes graphite ka mea hoʻomehana nui i hoʻohana ʻia i loko o ka umu ahi arc, kahi kaʻina hana kila kahi e hoʻoheheʻe ʻia ai ka ʻōpala mai nā kaʻa kahiko a i ʻole nā mea hana e hana i ke kila hou.
He ʻoi aku ka maʻalahi o ka hana ʻana o nā umu ahi uila ma mua o nā kapuahi pahū kuʻuna, ka mea i hana i ke kila mai ka hao hao a hoʻoulu ʻia e ka lanahu coking.Akā ʻoi aku ka kiʻekiʻe o ke kumukūʻai no ka hana ʻana i ke kila ma muli o ka hoʻohana ʻana i ka ʻōpala kila a hoʻohana ʻia e ka uila.
ʻO nā electrodes kahi ʻāpana o ka poʻi umu ahi a hoʻohui ʻia i loko o nā kolamu.A laila, hele ka uila ma nā electrodes, e hana ana i ka wela wela e hoʻoheheʻe ai i ke kila.ʻOkoʻa ka nui o nā electrodes akā hiki ke piʻi i ka 0.75 mika (2 a me ka hapa kapuaʻi) ke anawaena a hiki i ka 2.8 mika (9 kapuaʻi) ka lōʻihi.ʻOi aku ka nui ma mua o ʻelua metric tons.
Lawe ia i 3 kg (6.6 lb) o nā electrodes graphite e hana ai i hoʻokahi tonane kila.
E hiki ana ka piko o ka electrode i 3,000 degere Celsius, ka hapalua o ka wela o ka ili o ka la.Hana ʻia nā electrodes me ka graphite no ka mea hiki i ka graphite ke kū i ka wela nui.
Hoʻopili ʻia ka umu ahi ma kona ʻaoʻao e ninini i ke kila hoʻoheheʻe ʻia i loko o nā bākeke nunui i kapa ʻia ʻo ladles.Lawe nā kīʻaha i ke kila i hoʻoheheʻe ʻia i ka pahu wili kila, kahi e hana ai i nā huahana hou mai ka ʻōpala i hana hou ʻia.
ʻO ka uila e pono ai no kēia kaʻina hana ua lawa ia e hoʻoikaika i ke kūlanakauhale me ka heluna kanaka he 100,000.ʻO kēlā me kēia hehee i loko o kahi umu ahi uila hou e lawe ma kahi o 90 mau minuke a hana i 150 tone kila, lawa no kahi o 125 mau kaʻa.
ʻO Needle coke ka mea nui i hoʻohana ʻia i loko o nā electrodes i ʻōlelo ʻia e nā mea hana hiki ke hana a hiki i ʻeono mahina e hana ai me nā kaʻina hana me ka kuke ʻana a me ka rebaking e hoʻololi i ka coke i graphite.
Aia ka ʻaila coke ma muli o ka ʻaila a me ka coke nilala ma muli o ka lanahu, a hiki ke hoʻohana ʻia e hana i nā electrodes graphite.'O ka 'Pet coke' he huahana ia o ke ka'ina ho'oma'ema'e aila, oiai ua hana 'ia ka coke me ka lanahu mai ke kalo lanahu e 'ike 'ia ana i ka hana coke.
Ma lalo iho nei nā mea hana kiʻekiʻe o ka honua i nā electrodes graphite i koho ʻia e ka mana hana ma 2016:
