Wahi a ka ʻikepili a Baichuan Yingfu, ua hōʻike ʻia ke kumukūʻai o ka electrode graphite he 25420 yuan/ton i kēia lā, hoʻohālikelike ʻia me ka lā ma mua he 6.83%. Ua piʻi mau ke kumukūʻai o ka electrode graphite i kēia makahiki, me ke kumukūʻai hou loa i piʻi he 28.4% i hoʻohālikelike ʻia me ka hoʻomaka ʻana o ka makahiki.
ʻO ke piʻi ʻana o ke kumukūʻai o ka electrode graphite, ma ka ʻaoʻao hoʻokahi ma muli o ke kumukūʻai e piʻi nei, ma ka ʻaoʻao ʻē aʻe e pili ana i ka nāwaliwali o ka lako o ka ʻoihana.
Mai kēia makahiki, ke hoʻomau nei ke piʻi ʻana o nā kumukūʻai o ka graphite electrode petroleum coke ma luna, e like me ʻApelila 28, ua piʻi nui ke kumukūʻai o ka haʻahaʻa sulfur petroleum coke ma waena o 2,700-3680 yuan/ton i hoʻohālikelike ʻia me ka hoʻomaka ʻana o ka makahiki, he piʻi piha o kahi 57.18%. Mai ka makahiki i hala, ua hoʻopili ʻia e ka wela o ka mākeke mea anode, ʻoi aku ka nui o ke koi no ka hana ʻana i nā mea anode o ka graphitization a me ka graphite crucible i nā ʻoihana, ʻo ka ʻāpana o ka graphite electrode ma lalo o ka mana o ka loaʻa kālā o ka ʻoihana he graphitization electrode maikaʻi ʻole a me ka maikaʻi ʻole o ka ipu hoʻoheheʻe, e alakaʻi ana i ka hana ʻana o ka graphite electrode graphitization a me nā kumuwaiwai hana roasting, a ua hoʻonui ke kumukūʻai o ka graphite electrode graphitization.
Mai ʻOkakopa 2021, e hoʻomau ʻia ka palena ʻia o ka mākeke electrode graphite ma muli o nā palena hana palekana o ke kaiapuni i ka hāʻule a me ka hoʻoilo a me ka hopena o ke ahulau. I ka hopena o Malaki, ʻo ka nui o ka hana o ka mākeke electrode graphite ma kahi o 50%. ʻO kekahi mau ʻoihana electrode graphite liʻiliʻi a me ka waena ma lalo o ke kaomi pālua o ke kumukūʻai kiʻekiʻe a me ka nāwaliwali o ke koi ma lalo, ʻaʻole lawa ka mana hana. I ka manawa like, ua emi iho ka lawe ʻana mai o Kina o ka nila coke i ka hapaha mua o ka makahiki i hala ma kahi o 70%, ʻaʻole lawa ka hana holoʻokoʻa o ka mākeke electrode graphite.
Ka manawa hoʻouna: Mei-06-2022
