I kēia mau lā, ua hoʻomau ke kumukūʻai o nā electrodes graphite ultra-high-power kūloko i ke kiʻekiʻe a paʻa. E like me ka manawa paʻi, ke kumu kūʻai o ultra-high-power graphite electrode φ450 he 26,500-28,500 yuan / ton, a ʻo ke kumukūʻai o φ600 he 28,000-30,000 yuan / ton. He awelika ka hana, a ʻo ka hapa nui o lākou e kali a ʻike. I ka hoʻomaka ʻana o ka mahina, ua haʻahaʻa ke kumukūʻai kūʻai o nā wili kila, a ʻo ke kumukūʻai kūʻai o kekahi o lākou ua ʻoi aku ka kiʻekiʻe ma mua o ka mahina i hala, a ua kōkua ke kumukūʻai e kūpaʻa ma hope o ka piʻi ʻana.
Ma ka ʻaoʻao o lalo, ʻo ka awelika o ka hana ʻana o 85 mau hale wili kila arc kūʻokoʻa he 71.03%, ma lalo o 1.51% mahina-ma-mahina a me 12.25% makahiki-ma-makahiki. Ma waena o lākou, ʻo Kina Hikina a me Kina Hema komohana i hōʻike i kahi ʻano haʻahaʻa haʻahaʻa, a ʻo Kina Hikina Hikina i hōʻike i kahi ʻano piʻi iki. ʻO 82.61% ka nui o ka hana ʻana o ka umu puhi ahi o 247 wili kila, he piʻi o 0.70% mai ka pule i hala a me ka emi ʻana o 4.75% mai ka makahiki i hala. ʻAʻole kūpono ka nui o ka hana ʻana o nā umu uila, a he paʻakikī ke hoʻokumu koke i ke kākoʻo no ke kumukūʻai o nā electrodes graphite ultra-high-power ma hope o ka piʻi ʻana o ke kumukūʻai. I ka wā ma hope, ua hoʻopuka nā hale wili kila ʻehiku ma Kina Hema, Southwest Kina a me nā wahi ʻē aʻe i ka mālama ʻana a me ka hoʻohaʻahaʻa ʻana i nā hoʻolālā, hiki ke hoʻonui i ke kumukūʻai maikaʻi ʻole no kekahi mau kikoʻī o nā electrodes graphite ultra-high-power. kākoʻo.
Ma ke ʻano o nā kumukūʻai maka, ma hope o ka piʻi ʻana o ke kumukūʻai i ka pule i hala, ua paʻa mau ke kumukūʻai o ka aila ʻaila coke a me ka nila coke i kēia pule, akā ua paʻa ka mākeke. He piʻi o 47.36%. Ma muli o ke kaomi o nā kumukūʻai maka, ʻo ka hāʻawi holoʻokoʻa o nā electrodes graphite i ka mākeke ma ke ʻano i lalo, a ua hoʻololi kekahi o lākou i ka hana.
