Mai ka makahiki 2018, ua piʻi nui ka mana hana graphite electrode ma Kina.Wahi a ka ʻikepili o Baichuan Yingfu, ʻo 1.167 miliona tons ka nui o ka hana ʻana i ka makahiki 2016, me ka haʻahaʻa o ka hoʻohana ʻana ma lalo o 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 mana hana i 2021. 2017. I ka makahiki 2021, ʻo 53% ka hoʻohana ʻana o 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 ʻākau.I ka makahiki 2021, ʻoi aku ka nui o ka mana hana graphite electrode ma ʻĀkau a me ka ʻĀkau ʻĀkau Kina ma mua o 60%.Mai 2017 a 2021, e paʻa ka mana hana o "2 + 26" graphite electrode kūlanakauhale ma 400,000 a 460,000 tons.
Mai 2022 a 2023, e emi ana ka mana electrode graphite hou.Ma 2022, manaʻo ʻia ka mana he 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 kiʻekiʻe o ka ikehu, aia kekahi kānalua.
ʻO ka graphite electrode no ka hoʻohana ikehu kiʻekiʻe, kiʻekiʻe carbon emission ʻoihana.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 hoʻokuʻu ʻia he 1.4% o ke kumu kūʻai o ka electrode graphite kiʻekiʻe.ʻO ka hoʻohana mana i kēlā me kēia 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 o "ka mana pālua" o ka hoʻohana ʻana i ka ikehu, ua pāpā nui ʻia ka nui o ka hana o ke kila eAF i lalo me ka electrode graphite.Mai ka mahina ʻo Iune 2021, ʻo ka nui o ka hana o 71 eAF ʻoihana kila ma ka pae haʻahaʻa loa ma kahi o ʻekolu mau makahiki, a ua hoʻopau nui ʻia ka noi electrode graphite.
ʻO ka hoʻonui ʻana o ka graphite electrode output 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 mai ka 804,900 tons i ka makahiki 2014 a i 713,100 tons i ka makahiki 2019, kahi o 90%.Mai ka makahiki 2017, ʻo ka hoʻonui ʻia ʻana o ka lako graphite electrode a me ke koi ʻana i nā ʻāina ʻē aʻe mai ka ultra-high power graphite electrode, ʻo ia ke kumu o ka ulu nui ʻana o ka umu uila ma waho o ka ʻāina mai 2017 a 2018. Ma 2020, hana ʻia ma waho Ua hōʻole ke kila kapuahi uila ma muli o nā kumu maʻi 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 hao hao hao ma waho i ka 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.
