Manaʻo ka mākeke no ka graphite electrode e hoʻopaʻa inoa i kahi CAGR ma mua o 9% i ka wā wānana.ʻO ka mea maka mua i hoʻohana ʻia no ka hana ʻana i ka electrode graphite ʻo ia ka nila coke (ma ka petroleum a i ʻole ka lanahu).
Ke piʻi nei ka hana ʻana o ka hao a me ke kila ma nā ʻāina e kū mai ana, ke piʻi nei ka loaʻa ʻana o ka ʻōpala kila ma Kina e hoʻonui ai i ka hoʻohana ʻana i nā umu ahi uila e manaʻo ʻia e hoʻokau i ka noi no ka mākeke i ka wā wānana.
ʻO ka piʻi ʻana o nā kumukūʻai o ka coke needle e hopena i ka paʻa ʻana i waena o nā mea ʻē aʻe e like me ka ulu ʻana o ka UHP graphite electrode ma Kina a me ka hoʻohui ʻana o ka ʻoihana graphite electrode e keakea paha i ka ulu ʻana o ka mākeke.
ʻO ka piʻi ʻana o ka hana kila ma o ka ʻenehana ahi ahi ahi ma Kina e manaʻo ʻia e hana i manawa kūpono no ka mākeke i ka wā e hiki mai ana.
Nā Kūleʻa Kūʻai Nui
Hoʻonui i ka hana ʻana o ke kila ma o ka ʻenehana Uila Arc Furnace
- Lawe ka umu ahi arc i ke kila, DRI, HBI ( hao briquetted wela, i hoʻopaʻa ʻia DRI), a i ʻole hao puaʻa ma ke ʻano paʻa, a hoʻoheheʻe iā lākou e hana i ke kila.Ma ke ala EAF, hāʻawi ka uila i ka mana e hoʻoheheʻe i ka meaʻai.
- Hoʻohana nui ʻia ka graphite electrode i ke kaʻina hana ʻana i ka umu ahi arc (EAF), e hoʻoheheʻe i ka ʻōpala kila.Hana ʻia nā electrodes i ka graphite ma muli o kona hiki ke kū i nā wela kiʻekiʻe.I ka EAF, hiki i ka piko o ka electrode ke hiki i 3,000 Fahrenheit, ʻo ia ka hapalua o ka mahana o ka ili o ka lā.'Oko'a ka nui o nā electrodes, mai 75mm ka anawaena, a hiki i ka 750mm ka nui, a hiki i ka 2,800mm ka lō'ihi.
- ʻO ka piʻi ʻana o ke kumukūʻai o nā electrodes graphite i hoʻonui i nā kumukūʻai o nā hale wili EAF.Manaʻo ʻia ka EAF ma kahi o 1.7 kg o nā electrodes graphite e hana ai i hoʻokahi metric ton o ke kila.
- ʻO ka piʻi ʻana o ke kumukūʻai e pili ana i ka hoʻohui ʻana o ka ʻoihana, ma ka honua holoʻokoʻa, ka pani ʻana o ka hiki ma Kina, ma hope o ka hoʻoponopono ʻana i ka kaiapuni, a me ka ulu ʻana o ka hana EAF, ma ka honua.Manaʻo ʻia kēia e hoʻonui i ke kumukūʻai hana o EAF ma 1-5%, e pili ana i nā hana kūʻai ʻana o ka wili, a hiki paha i kēia ke kaohi i ka hana kila, no ka mea, ʻaʻohe mea pani no ka graphite electrode i nā hana EAF.
- Eia kekahi, ua hoʻoikaika ʻia nā kulekele o Kina e hoʻoponopono i ka pollution ea e nā pale hoʻolako ikaika, ʻaʻole wale no ka ʻāpana kila, akā pū kekahi me ka lanahu, zinc, a me nā ʻāpana ʻē aʻe e hoʻoulu ai i ka pollution particulate.ʻO ka hopena, ua emi nui ka hana kila Kina i nā makahiki i hala.Eia naʻe, manaʻo ʻia e loaʻa ka hopena maikaʻi i nā kumukūʻai kila a me nā wili kila ma ka ʻāina, e ʻoliʻoli i nā palena maikaʻi.
- ʻO nā mea āpau i ʻōlelo ʻia aʻe, manaʻo ʻia e hoʻokele i ka mākeke electrode graphite i ka wā wānana.
ʻĀpana Asia-Pākīpika e hoʻomalu i ka mākeke
- Ua lanakila ka ʻāina ʻo Asia-Pacific i ka māhele mākeke honua.Noho ʻo Kina i ka hapa nui loa e pili ana i ka hoʻohana ʻana a me ka hiki ke hana i nā electrodes graphite i ka hanana honua.
- ʻO ke kulekele hou i kauoha ʻia ma Beijing a me nā panalāʻau nui ʻē aʻe o ka ʻāina e hoʻoikaika i nā mea hana kila e pani i ka mana o 1.25 miliona tons o ke kila i hana ʻia ma ke ala ʻino i ke kaiapuni i mea e hana ai i kahi mana hou o 1 miliona ton o ke kila.Ua kākoʻo ia mau kulekele i ka hoʻololi ʻana o nā mea hana mai nā ʻano hana maʻamau o ka hana kila i ke ʻano EAF.
- ʻO ka ulu nui ʻana o nā kaʻa kaʻa, me ka hoʻonui ʻana i ka ʻoihana kūkulu hale, ke manaʻo ʻia e kākoʻo i ka noi home no nā alloys non-ferrous a me ka hao a me ke kila, kahi kumu kūpono no ka ulu ʻana o ka koi graphite electrode i nā makahiki e hiki mai ana.
- ʻO ka mana hana o kēia manawa o UHP graphite electrodes ma Kina ma kahi o 50 tausani metric ton i kēlā me kēia makahiki.Manaʻo ʻia ke koi no nā electrodes UHP ma Kina e ʻike i ka ulu nui ʻana i ka wā lōʻihi a me ka mana hou o ka 50 tausani metric ton o UHP graphite electrodes e manaʻo ʻia e ʻike ʻia e nā pae hope o ka wā wānana.
- ʻO nā mea āpau i ʻōlelo ʻia ma luna, e manaʻo ʻia e hoʻonui i ka noi no ka electrode graphite i ka ʻāina i ka wā wānana.
