Mai ka makahiki 2018, ua hoʻonui nui ʻia ka mana hana graphite electrode ma Kina. Wahi a ka ʻikepili a Baichuan Yingfu, ʻo 1.167 miliona tons ka nui o ka hana ʻana i ka makahiki 2016, me ka haʻahaʻa o ka hoʻohana ʻana i ka hiki he 43.63%. I ka makahiki 2017, hiki i ka graphite electrode hana o Kina i ka liʻiliʻi loa o 1.095 miliona tons, a laila me ka hoʻomaikaʻi ʻana i ka pōmaikaʻi o ka ʻoihana, e hoʻomau ʻia ka hana hana i 2021. 2017. I ka makahiki 2021, ʻo 53% ka hoʻohana ʻana i ka ʻoihana. I ka makahiki 2018, hiki i ka 61.68% ka nui o ka hoʻohana ʻana i ka nui o ka hoʻohana ʻana i ka graphite electrode, a laila hoʻomau ka emi ʻana. Manaʻo ʻia ka hoʻohana ʻana i ka mana ma 2021 he 53%. Hāʻawi nui ʻia ka mana o ka ʻoihana graphite electrode ma Kina akau a me Kina hikina. I ka makahiki 2021, ʻoi aku ka nui o ka mana hana graphite electrode ma ʻĀkau a me ka hikina ʻākau o Kina ma mua o 60%. Mai 2017 a 2021, e paʻa ka mana hana o "2 + 26" electrode graphite kūlanakauhale ma 400,000 a 460,000 tons.
Mai 2022 a i 2023, e emi iho ka mana electrode graphite hou. I ka makahiki 2022, manaʻo ʻia ka nui o 120,000 tons, a ma 2023, manaʻo ʻia ka mana electrode graphite hou he 270,000 tons. Hiki ke hoʻokomo ʻia kēia ʻāpana o ka mana hana i ka wā e hiki mai ana i ka loaʻa kālā o ka mākeke electrode graphite a me ka nānā ʻana o ke aupuni i ka ʻoihana hoʻohana ikehu kiʻekiʻe, aia kekahi kānalua.
ʻO ka graphite electrode no ka hoʻohana ikehu kiʻekiʻe, ʻoihana hoʻokuʻu kalapona kiʻekiʻe. ʻO ka hoʻokuʻu kalapona i kēlā me kēia tona o ka electrode graphite he 4.48 tons, ʻoi aku ka haʻahaʻa i ka metala silika a me ka alumini electrolytic. Ma muli o ke kumu kūʻai kalapona o 58 yuan/ton ma Ianuali 10, 2022, ʻo ke kumu kūʻai kalapona e hoʻokuʻu ʻia no 1.4% o ke kumu kūʻai o ka electrode graphite kiʻekiʻe. ʻO ka hoʻohana ʻana i ka mana no ka ton o ka electrode graphite he 6000 KWH. Inā helu ʻia ke kumukūʻai uila ma 0.5 yuan/KWH, ʻo ke kumukūʻai uila he 16% o ke kumukūʻai o ka electrode graphite.
Ma lalo o ke kāʻei ʻana o ka "mana ʻelua" o ka hoʻohana ʻana i ka ikehu, ua pāpā nui ʻia ka hana o ka hao eAF i lalo me ka electrode graphite. Mai ka mahina ʻo Iune 2021, ʻo ka nui o ka hana ʻana o nā ʻoihana kila eAF he 71 i ka pae haʻahaʻa loa i loko o ʻekolu mau makahiki, a ua kāohi nui ʻia ke koi electrode graphite.
ʻO ka hoʻonui ʻana o ka puka graphite electrode o waho a me ka hāʻawi ʻana a me ke koi ʻana i ka nui no ka ultra-high power graphite electrode. Wahi a Frost & Sullivan data, ua emi iho ka puka o ka graphite electrode ma nā ʻāina ʻē aʻe o ka honua mai 804,900 tons i 2014 a i 713,100 tons i 2019, kahi o ka hopena o ka ultra-high power graphite electrode i helu ʻia ma kahi o 90%. Mai ka makahiki 2017, ʻo ka hoʻonui ʻia ʻana o ka hāʻawi ʻana i ka graphite electrode a me ke koi ʻana i nā ʻāina ʻē aʻe mai ka ultra-high power graphite electrode, ka mea ma muli o ka ulu nui ʻana o ka umu uila o nā ʻāina ʻē aʻe mai 2017 a 2018. Ma 2020, hana ʻia ma waho Ua hōʻole ke kila umu ahi uila ma muli o nā kumu ahulau. I ka makahiki 2019, ua hōʻea ʻo Kina i ka graphite electrode i 396,300 tons. I ka makahiki 2020, i hoʻopilikia ʻia e ka maʻi ahulau, ua hāʻule nui ka hana ʻana o ka umu ahi uila ma waho o 396 miliona tons, i lalo o 4.39% makahiki ma ka makahiki, a ua hāʻule ka hoʻokuʻu ʻana o Kina i ka graphite electrode i 333,900 tons, i lalo o 15.76% makahiki ma ka makahiki.
