Nā manaʻo e pili ana i ke kumukūʻai makeke o ka aila kuni ma Kina i nā lā ʻelua i hala iho nei

I nā lā ʻelua i hala iho nei, ʻoi aku ka maikaʻi o ke kālepa mākeke o ka coke petroleum calcined ma Kina, a paʻa ka hoʻomaka ʻana o nā ʻoihana. Steel kalapona makeke noi aoao o ka ho'āla kū'ai 'ana he laulā, e hookokoke ana i ka Spring Festival, downstream haawe hoomau i ka emi; He maikaʻi ke kūʻai ʻana o ka mākeke i ke kalapona alumini, ʻoi aku ka ikaika o ke kālepa mākeke, a paʻa ke kumukūʻai mākeke o ka char calcined no kekahi manawa. Ua komo ka mākeke ʻaila aila haʻahaʻa hikina akau i ka mākeke ma ke ʻano maikaʻi, ua hoʻomau ka piʻi ʻana o ke kumukūʻai o nā kumu waiwai haʻahaʻa haʻahaʻa, ʻo ka graphite electrode a me nā mākeke cathode graphite i makemake nui ʻia, a ʻo nā kumukūʻai haʻahaʻa sulfur char market i kūpaʻa nui. ʻAʻole i hoʻemi ʻia ke kākoʻo o ka mākeke haʻahaʻa sulfur maka, ʻoi aku ka maikaʻi o ka hoʻoulu ʻana o ka waihona i lalo, ua hoʻonui ʻia ka waiwai o ka hui, a ua manaʻo ʻia e kūpaʻa ke kumukūʻai o ka sulfur calcined char haʻahaʻa. He maikaʻi nō ka mākeke waiwai electrode maikaʻi ʻole, a maikaʻi ke kūlana kauoha o nā ʻoihana, e kākoʻo ana i ke kumukūʻai maʻamau o ka sulfur; Loaʻa i nā mea kanu alumini nā koi koʻikoʻi no ka trace element, paʻa ka mākeke index, kiʻekiʻe ke kumu kūʻai o ke kumu waiwai, a ke piʻi nei ke kumukūʻai kūʻai o nā huahana sulfur index kiʻekiʻe. Manaʻo ʻia ka mākeke sulfur char medium a kiʻekiʻe e hana mau.
