Wahi a baichuan Yingfu ʻikepili, graphite electrode i haʻi ʻia he 25420 yuan/ton i kēia lā, ke hoʻohālikelike ʻia me ka lā ma mua 6.83%. Ua piʻi mau ke kumukūʻai o ka graphite electrode i kēia makahiki, me ke kumu kūʻai hou loa i 28.4% i hoʻohālikelike ʻia me ka hoʻomaka o ka makahiki.
ʻO ka piʻi ʻana o ke kumukūʻai graphite electrode, ma kekahi ʻaoʻao ma muli o ka piʻi ʻana o ke kumukūʻai, ma ka ʻaoʻao ʻē aʻe e pili ana i ka nāwaliwali o ka lako ʻoihana.
Mai kēia makahiki, ke hoʻomau nei ka piʻi ʻana o ke kumukūʻai o ka graphite electrode upstream petroleum coke, ma ka lā 28 ʻApelila, hoʻonui nui ʻia nā kumukūʻai sulfur petroleum coke 2,700-3680 yuan / ton i hoʻohālikelike ʻia me ka hoʻomaka ʻana o ka makahiki, kahi piʻi nui o kahi 57.18%. Mai ka makahiki i hala aku nei, ua hoʻohuli ʻia e ka mākeke waiwai anode wela, ʻoi aku ka nui o ka ʻoihana hana anode o ka graphitization a me ka graphite crucible koi, ʻo ka ʻāpana o ka electrode graphite ma lalo o ka mana o ka loaʻa ʻana o ka ʻoihana he graphitization electrode maikaʻi ʻole a me ka crucible maikaʻi ʻole, alakaʻi i ka hana o ka graphite electrode. ka graphitization a me ka hoʻoheheʻe ʻana i nā kumuwaiwai e hoʻoponopono i nā kumuwaiwai hopohopo, graphite electrode graphitization i ke kumukūʻai.
Mai ʻOkakopa 2021, e hoʻomau ʻia ka mākeke graphite electrode ma muli o nā palena o ka hana ʻana i ka mālama ʻana i ke kaiapuni i ka hāʻule a me ka hoʻoilo a me ka hopena o ka maʻi maʻi. Ma ka hopena o Malaki, ʻo ka nui o ka hana holoʻokoʻa o ka mākeke electrode graphite ma kahi o 50%. ʻO kekahi mau ʻoihana graphite electrode liʻiliʻi a me ka nui ma lalo o ke kaomi pālua o ke kumukūʻai kiʻekiʻe a me ka noi haʻahaʻa haʻahaʻa, ʻaʻole lawa ka mana hana. I ka manawa like, ʻo ka lawe ʻana mai o Kina i ka coke needle i ka hapaha mua o ka makahiki i hala ua emi iho ma kahi o 70%, ʻaʻole lawa ka hana holoʻokoʻa o ka mākeke electrode graphite.
