I ka hapalua i hala o 2021, ma lalo o nā kumu kulekele like ʻole, ke hāpai nei ka carburizer coke aila i ka mea pālua o ke kumukūʻai o nā mea maka a me ka nāwaliwali o ke koi. Ua piʻi aʻe ke kumukūʻai o nā mea maka ma mua o 50%, ua koi ʻia kekahi hapa o ka hale hana kānana e hoʻōki i ka ʻoihana, ke hakakā nei ka mākeke carburizer.

ʻO ka pakuhi o ke kumukūʻai o ka petroleum coke ma nā kumu hoʻohālike kaulana o ka ʻāina
Wahi a nā helu helu, mai ka hopena o Mei, ua hōʻike ke kumukūʻai o ka coke petroleum kūloko i kahi ʻano piʻi, ʻoi aku hoʻi mai ʻAukake a i kēia manawa, ua wikiwiki loa ka piʻi ʻana. I waena o lākou, ʻo ke kumukūʻai mākeke o 1#A he 5000 yuan/ton, piʻi 1900 yuan/ton a i ʻole 61.29%. ʻO ke kumukūʻai mākeke 1#B he 4700 yuan/ton, piʻi 2000 yuan/ton a i ʻole 74.07%. ʻO ke kumukūʻai mākeke 2# coke he 4500 yuan/ton, piʻi 1980 yuan/ton a i ʻole 78.57%. Piʻi ke kumukūʻai o nā mea maka, e hoʻokele ana i nā kumukūʻai carburizer.
Ma hope o ke kūʻai nui ʻana o ka mākeke coke carburizing agent calcination, ʻo ke kumukūʻai nui he 5500 yuan/ton (ka nui o ka ʻāpana: 1-5mm, C: 98%, S≤0.5%), 1800 yuan/ton a i ʻole 48.64% kiʻekiʻe ma mua o ka wā ma mua. Ke piʻi ikaika nei ke kumukūʻai o nā mea maka, piʻi koke ke kumukūʻai kūʻai, kali nā mea hana carburizer coke calcined a ʻike i ka lewa ikaika, mākeke akahele. Ma ke ʻano laulā, ua maopopo ka manaʻo bearish o nā mea hana. Ma muli o ke kumukūʻai kiʻekiʻe o kekahi mau ʻoihana, hoʻemi i nā mea kānana a pani pololei paha, ʻaʻole maopopo ka hoʻomaka hou ʻana o ka manawa hana.
ʻO ke kumukūʻai nui o ka mākeke carburizer graphitization he 5900 yuan/ton (ka nui o ka ʻāpana: 1-5mm, C: 98.5%, S≤0.05%), 1000 yuan/ton a i ʻole 20.41% kiʻekiʻe ma mua o ka wā ma mua. Lohi iki ka piʻi ʻana o ke kumukūʻai carburizer graphitization, loaʻa i nā ʻoihana pākahi ka uku hana no ka hana ʻana i nā mea anode. Hāʻawi kekahi mau ʻoihana ma hope i ka carburizer calcined e hoʻohana i ka carburizer semi-graphitized, e hoʻonui ana i ke kumukūʻai o ka carburizer.
I kēia manawa, nui nō ka loli o ke ʻano o ka hoʻokuʻu ʻana o ke kahua kikowaena, nāwaliwali ka hana ma ka mākeke holoʻokoʻa. I kēia mau lā iho nei, ma muli o ke anuanu ma ka ʻāpana ʻākau, ua lohi ke kūkulu ʻana, ʻoiai kūpono nō ka ʻāpana hema no ke kau kūkulu. Ua hōʻike kekahi mau kūlanakauhale ma ka Hikina a me Kina Hema i ke kūlana o nā kikoʻī i waho o ka waihona, a ʻo nā kikoʻī i waho o ka waihona he mau kikoʻī nui, ʻoiai ke koi maoli i ka hopena e mau ana. Me ka holomua mālie o ka manawa, e loaʻa mau ana i ke koi kikowaena kahi manawa nui o ka hana maikaʻi.
Ke hoʻomau nei ke piʻi ʻana o nā kumukūʻai mea maka, e hāʻawi i ke kākoʻo kumukūʻai no ka recarburizer, akā pono ka manawa no ke koi ma lalo, i ka wā pōkole, e hoʻonui i ka mana kiʻekiʻe. Ua hoʻōki kekahi hapa o nā mea kanu kānana i ka hana ʻana no kekahi manawa, ʻaʻole paha e hiki ke hoʻomaikaʻi i ka lako no ka wā pōkole. Manaʻo ʻia e hoʻomau ke kumukūʻai mākeke carburizer coke aila i ka hana ikaika o nā kumukūʻai mea maka.
Ka manawa hoʻouna: ʻOkakopa-29-2021
