ʻIke mālie ʻia nā ʻōpū o ka graphitization, e hoʻomau ka piʻi ʻana o nā electrodes graphite

I kēia pule, ua hoʻomau ke kumukūʻai o ka mākeke electrode graphite kūloko i kahi ʻano paʻa a piʻi. I waena o lākou, ua ikaika iki ka UHP400-450mm, a ua paʻa ke kumukūʻai o nā kikoʻī UHP500mm a ʻoi aku paha no kekahi manawa. Ma muli o ka palena o ka hana ʻana ma ka ʻāina ʻo Tangshan, ua komo koke nā kumukūʻai kila i kahi nalu ʻelua o ke ʻano piʻi. I kēia manawa, ʻo ka loaʻa kālā no kēlā me kēia tona o ke kila umu uila ma kahi o 400 yuan, a ʻo ka loaʻa kālā no kēlā me kēia tona o ke kila umu pahū ma kahi o 800 yuan. Ua piʻi nui ka nui o ka hana holoʻokoʻa o ke kila umu uila i 90.%, i hoʻohālikelike ʻia me ka nui o ka hana o ka manawa like o nā makahiki i hala, ua nui ka piʻi ʻana. I kēia manawa, ua hoʻonui nui ʻia ke koi no nā electrodes graphite e nā wili kila.

ʻAno mākeke
Ma muli o ke kāohi pālua o ka pono o ka ikehu ma Inner Mongolia a me ka hoʻemi ʻana o ka uila ma Gansu a me nā wahi ʻē aʻe mai Ianuali a Malaki, ua lilo ke kaʻina hana graphitization electrode graphite i mea pilikia nui. E like me kā mākou e ʻike nei, ʻo Inner Mongolia kahi kumu graphitization, a ua hiki ka hopena palena o kēia manawa i 50%-70%, hapalua kaʻina hana. He palena loa ka nui o nā huahana i hoʻopau ʻia e nā mea hana electrode graphite. I ke komo ʻana i ka hoʻomaka o ʻApelila, ua pau ka pōʻai hope loa o ke kau kūʻai wili kila, akā ʻaʻole lawa ka waihona o nā mea hana electrode graphite nui, a ke manaʻo ʻia nei e hoʻomau ka piʻi ʻana o nā electrodes graphite i ka wā e hiki mai ana.

Nā mea maka
Ua hoʻokiʻekiʻe hou ʻia ke kumukūʻai o Jinxi ma mua o ka hale hana ma 300 yuan/ton i kēia pule. I kēia Pōʻahā, ua mau ke kumukūʻai o ka Fushun Petrochemical 1#A petroleum coke ma 5,200 yuan/ton, a ʻo ke kumukūʻai o ka low-sulfur calcined coke he 5600-5800 yuan/ton, he piʻi o 100 yuan/ton. Ua komo ʻo Ton. Dagang i ka hoʻoponopono hou ʻana, a e mau ana ka hoʻoponopono hou ʻana no 45 mau lā. Ua paʻa iki nā kumukūʻai nila coke kūloko i kēia pule. I kēia manawa, ʻo ke kumukūʻai nui o nā huahana lanahu kūloko a me nā huahana aila he 8500-11000 yuan/ton.

ʻAno o ka hale hana kila
Ke hoʻomau nei ke piʻi ʻana o nā kumukūʻai kila kūloko i kēia pule, me kahi pae o 150 yuan/ton. Kūʻai nui nā mea hoʻohana hope ma ke koi. Ke manaʻolana nei nā mea kūʻai aku me ka akahele e pili ana i ka nānā ʻana o ka mākeke. Aia nō nā waihona ma lalo o kekahi kaomi. ʻO ka nānā ʻana o ka mākeke e hilinaʻi nui ʻia inā hiki ke piʻi ka noi i ka hoʻomaka o ʻApelila. I kēia manawa, ua hōʻea ka loaʻa kālā o nā hale hana kila umu uila he nui i 400-500 yuan/ton, a ua ʻoi aku ka nui o ka hana o nā umu uila ma ka ʻāina holoʻokoʻa ma mua o 85%.
