ʻO ka mea nui i hoʻohana ʻia i ka hana ʻana i ka electrode graphite he calcined petroleum coke. No laila he aha ke ʻano o ka coke petroleum calcined i kūpono no ka hana ʻana i ka electrode graphite?
1. ʻO ka hoʻomākaukau ʻana i ka aila coking maka e kūpono i ke kumu o ka hana ʻana i ka coke petroleum kiʻekiʻe, a ʻo ka hoʻopaʻa inoa ʻana i ka coke petroleum kiʻekiʻe e ʻoi aku ka nui o ka fibrous. Hōʻike ka hana hana i ka hoʻohui ʻana i ka 20-30% thermal cracking koena coke i loko o ka coking maka aila ʻoi aku ka maikaʻi, hiki ke hoʻokō i nā koi o ka graphite electrode.
2. ʻO ka ikaika hoʻolālā kūpono.
ʻO ke anawaena o ka maka ma mua o ka ʻohi ʻana, ka hoʻoheheʻe ʻana, ka wā e hōʻemi ai i ka pulverization, e hoʻokō i nā koi o ka batching square grain size composition.
3. Pono e liʻiliʻi ka hoʻololi o ka leo o ka coke ma hope o ka haki ʻana, hiki ke hoʻemi i ke koʻikoʻi o loko o ka huahana ma muli o ka hoʻi ʻana o ka huahana i kaomi ʻia a me ka emi ʻana o ke kaʻina hana ʻana a me ka graphitization.
4. Pono e maʻalahi ka Coke i ka graphitization, pono nā huahana i haʻahaʻa haʻahaʻa, kiʻekiʻe thermal conductivity a haʻahaʻa coefficient o ka hoʻonui wela.
5. Pono e emi iho ka nui o ka coke ma mua o 1%,Hōʻike ka mea volatile i ka hohonu o ka coking a pili i ke ʻano o nā waiwai.
6. Pono e kālua ʻia ka Coke ma 1300 ℃ no 5 mau hola, a ʻaʻole i emi iho kona umekaumaha maoli ma mua o 2.17g/cm2.
7. ʻAʻole pono ke kiʻekiʻe o ka sulfur i loko o ka coke ma mua o 0.5%.
ʻO ʻAmelika ʻĀkau a me ʻAmelika Hema nā mea hana nui o ka coke petroleum ma ka honua, ʻoiai ʻo ʻEulopa ka mea pono ponoʻī i ka petroleum coke. ʻO nā mea hana nui o ka petroleum coke ma Asia ʻo Kuwait, Indonesia, Taiwan a me Iapana a me nā ʻāina a me nā ʻāina ʻē aʻe.
Mai ka makahiki 1990, me ka ulu wikiwiki ʻana o ka hoʻokele waiwai o Kina, ke piʻi nei ka noi no ka aila i kēlā me kēia makahiki.
Ke hoʻonui nui ʻia ka nui o ka hoʻoili ʻana i ka aila, e hana ʻia ka nui o ka petroleum coke, kahi huahana o ka hoʻomaʻemaʻe ʻaila.
Wahi a ka māhele ʻāina o ka ʻaila coke i Kina, ʻo ka ʻāina ʻo Kina hikina ke kūlana mua, ʻoi aku ma mua o 50% o ka huina o ka ʻaila coke ma Kina.
Ua ukali ʻia e ka ʻāina hikina akau a me ka ʻāina komohana ʻākau.
He kuleana koʻikoʻi ka sulfur maʻiʻo o ka petroleum coke i kāna noi a me ke kumukūʻai, a ua kaupalena ʻia ka hana ʻana o ka petroleum coke graphitized e nā lula kūlohelohe ma waho, e kāohi ana i ka puhi ʻana o ka petroleum coke me ka nui o ka sulfur content i nā refineries a me nā mea kanu mana ma ka ʻāina.
ʻO ke kiʻekiʻe kiʻekiʻe a me ka haʻahaʻa sulfur petroleum coke e hoʻohana nui ʻia i nā ʻoihana kila, aluminika a me nā kalapona. ʻO ka piʻi ʻana o ka noi e hoʻonui i ka waiwai o ka petroleum coke i nā manawa he nui.
I kēia mau makahiki i hala iho nei, ke hoʻomau nei ka ʻai ʻana o ka coke petroleum ma Kina i ka wikiwiki kiʻekiʻe, a ke hoʻonui mau nei ka noi no ka petroleum coke ma nā mākeke mea kūʻai aku.
ʻOi aku ka hapalua o ka nui o ka hoʻohana ʻana i ka ʻaila coke ma Kina. Hoʻohana nui ʻia i ka anode pre-baked, a ʻoi aku ka nui o ke koi no ka coke sulfur medium a haʻahaʻa.
ʻO nā huahana kalapona e pili ana i kahi hapalima o ke koi no ka coke petroleum, ka mea i hoʻohana nui ʻia e hoʻomākaukau i nā electrodes graphite. He kiʻekiʻe ka waiwai o nā electrodes graphite kiʻekiʻe a he waiwai nui.
Hoʻokahi hapaʻumi o ka hoʻohana ʻana i ka wahie, a ʻoi aku ka nui o nā mea kanu mana, porcelain a me nā hale aniani.
ʻO ka lākiō hoʻohana ʻoihana hoʻoheheʻe ʻana o ka hoʻokahi - iwakālua, ka hoʻohana ʻana i ka wili hao hao.
Eia kekahi, ʻo ka koi ʻana o ka ʻoihana silika he mea ikaika e helu ʻia.
ʻO ka hapa liʻiliʻi loa ka ʻāpana o ka hoʻokuʻu ʻana, akā ʻo ke koi ʻana i ka coke petroleum kiʻekiʻe ma ka mākeke o nā ʻāina ʻē he mea pono ke nānā i mua. Aia kekahi mahele o ka coke sulfur kiʻekiʻe, a me ka ʻai ʻana i ka ʻai hale.
Me ka ulu ʻana o ka hoʻokele waiwai o Kina, ua hoʻomaikaʻi maikaʻi ʻia nā hale wili kila o Kina, nā mea hoʻoheheʻe alumini a me nā pono waiwai ʻē aʻe, i mea e hoʻonui ai i ka huahana a me ka maikaʻi o nā huahana, nui nā ʻoihana nui i kūʻai mālie i ka graphenized petroleum coking carbonizer. Ke piʻi nei ka makemake o ka home. ʻO ka manawa like, ma muli o ke kumukūʻai hana kiʻekiʻe, ka nui o ka hoʻopukapuka kālā a me nā koi ʻenehana kiʻekiʻe i ka hana ʻana i ka graphitized petroleum coke, ʻaʻole nui ka nui o nā ʻoihana hana a me ka emi ʻana o ka hoʻokūkū hoʻokūkū i kēia manawa, no laila ke ʻōlelo nei, nui ka mākeke, ʻo ka lako. liʻiliʻi, a ʻoi aku ka liʻiliʻi o ka lako holoʻokoʻa ma mua o ka noi.
I kēia manawa, ʻo ke kūlana mākeke coke o Kina, ʻoi aku ka nui o nā huahana coke sulfur petroleum coke, i hoʻohana nui ʻia e like me ka wahie;
Hoʻopau ʻia ke kaʻina calcination petroleum coke haole i loko o ka refinery, ʻo ka petroleum coke i hana ʻia e ka refinery hele pololei i loko o ka calcination unit no ka calcination.
No ka mea, ʻaʻohe mea calcination i loko o nā hale hoʻoheheʻe hale, kūʻai ʻia ka petroleum coke i hana ʻia e nā refineries ma ke kumukūʻai.
