Bauxite i hoʻokalaka ʻia
ʻIke Huahana
Bauxite i hoʻokalaka ʻiaʻo ia kekahi o nā ʻai nui o ka alumini. Loaʻa ka bauxite calcined i loko o ka pahu Rotary ma ke calcining ʻana i ka bauxite papa kiʻekiʻe ma ka mahana kiʻekiʻe (mai 850ºC a i 1600ºC) i loko o ka pahu rotary. Hoʻopau kēia i ka makū a laila e hoʻonui ai i ka ʻike alumina.
Ua māhele ʻia ka bauxite i calcined ʻia i loko o ka bauxite papa kūikawā, ka bauxite papa mua, ka bauxite papa ʻelua, a me ka bauxite papa ʻekolu e like me ka nui o nā mea haumia e like me Al2O3, Fe2O3, a me SiO2, a me ka nui o ka clinker a me ka omo wai. I mea e maʻalahi ai ke kūʻai ʻana a nā mea kūʻai aku, hoʻohana kā mākou hale hana i ka nui o ka bauxite Al2o3 ma ke ʻano he lepili e hoʻokaʻawale iā ia i 55, 65, 70, 75, 80, 85, 88 a me 90.
Eia kekahi, ma o ka calcination, e hoʻomaikaʻi ʻia ke kūpaʻa o ka density a me ka refractory i nā kekelē like ʻole. Hiki ke hoʻonui nui ʻia ke ʻano o ka bauxite.
Hiki ke hana ʻia ka bauxite i calcined ʻia i one bauxite a me ka pauka bauxite o nā nui ʻāpana like ʻole, hiki ke hoʻohana pololei ʻia nā mea ʻelua e like me ke one refractory. He kūlana kiʻekiʻe loa ia ma ke kahua o nā mea refractory.

1. Hana ʻana i nā mea refractory kiʻekiʻe:Hoʻohana pinepine ʻia ka bauxite i hoʻopaʻa ʻia e hana i nā piliki refractory like ʻole, nā mea hoʻoheheʻe refractory, a pēlā aku ma muli o kona kūpaʻa wela kiʻekiʻe a me ke kūpaʻa kemika. Hoʻohana nui ʻia kēia mau mea refractory i nā kahua ʻoihana wela kiʻekiʻe e like me ke kila, ka metallurgy non-ferrous, ke aniani, ka sima, a pēlā aku, a hoʻohana ʻia e kūkulu i nā ʻāpana koʻikoʻi e like me nā paia umu, nā luna umu, a me nā lalo umu e hōʻoia i ka palekana hana a me ka maikaʻi o ka huahana i nā wahi wela kiʻekiʻe.
2. Hoʻolei pololei:Hiki ke hana ʻia ka clinker bauxite calcined i pauka maikaʻi no ka hana ʻana
nā ʻōmole hoʻolei, kūpono no ka hoʻolei pololei ʻana i nā keʻena koa, aerospace, kamaʻilio, mea hana, mīkini, a me nā lako lapaʻau. ʻO kona pololei kiʻekiʻe a me ke kūpaʻa wela kiʻekiʻe e hōʻoia i ka maikaʻi a me ka hana o nā huahana hoʻolei.
3. Hana ʻana i ka fiber refractory silicate alumini:Ma hope o ka hoʻoheheʻe ʻia ʻana o ka clinker alumini kiʻekiʻe i ka mahana kiʻekiʻe, kāpīpī ʻia me ka ea a i ʻole ka mahu me ke kaomi kiʻekiʻe a me ka wikiwiki, a hoʻomaʻalili ʻia, hiki ke hana ʻia i loko o ka fiber refractory silicate alumini. Loaʻa i kēia fiber nā pono o ke kaumaha māmā, ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa wela maikaʻi, a me ka conductivity wela haʻahaʻa. Hiki ke hoʻohana ʻia i nā ʻano ʻoihana like ʻole e like me ke kila, ka metallurgy non-ferrous, nā mea uila, ka petroleum, ka ʻoihana kemika,
a me ka mokulele.
4. Mea lawe mea hoʻouluulu:I loko o ka ʻoihana kemika, hiki ke hoʻohana ʻia ka bauxite calcined e hana i nā mea lawe catalyst, hoʻomaikaʻi i ka hana a me ke kūpaʻa o nā catalysts, a hoʻolōʻihi i ke ola lawelawe o nā catalysts.
5. Hana ʻana i ka sima:Hoʻohui ʻia ka bauxite i hoʻopaʻa ʻia i ka sima ma ke ʻano he mea hoʻohui, hiki ke hoʻomaikaʻi nui i ka ikaika a me ke kūpaʻa o ka sima, me ka hoʻomaikaʻi ʻana i ka wai a me ka anti-permeability o ka sima a me ka hoʻemi ʻana i nā kumukūʻai hana.
6. Hana ʻana i ka seramika:He mea pono ʻole ka bauxite i hoʻopaʻa ʻia i ka hana ʻana i ka seramika. Ma hope o ka mālama ʻana i ka mahana kiʻekiʻe, hoʻomaikaʻi nui ia i ka refractoriness, ka ikaika mechanical a me ke kūpaʻa ʻana i ka haki o nā seramika, e hāʻawi ana i nā seramika i kahi hopena hoʻonaninani kū hoʻokahi.
7. Mea Hoʻopili Pālolo:I ka ʻeli ʻana i ka ʻaila a me ke kinoea, hiki ke hoʻohana ʻia ka bauxite calcined 200 mesh e like me ka mea hoʻohui keramika e hoʻomaikaʻi ai i ka pono o ka ʻeli ʻana.

ʻO Shandong Robert New Material Co., Ltd.Aia ma ke kūlanakauhale ʻo Zibo, ka moku ʻo Shandong, Kina, he kahua hana mea refractory. He ʻoihana hou mākou e hoʻohui i ka noiʻi a me ka hoʻomohala ʻana, ka hana ʻana, ke kūʻai aku ʻana, ka hoʻolālā a me ke kūkulu ʻana i ka umu, ka ʻenehana, a me ka hoʻokuʻu aku i nā mea refractory. Loaʻa iā mākou nā lako piha, nā ʻenehana holomua, ka ikaika loea ikaika, ka maikaʻi o ka huahana maikaʻi loa, a me ka inoa maikaʻi. Uhi kā mākou hale hana ma mua o 200 ʻeka a ʻo ka hopena makahiki o nā mea refractory i hoʻohālikelike ʻia he 30000 tons a ʻo nā mea refractory i hoʻohālikelike ʻole ʻia he 12000 tons.
ʻO kā mākou huahana nui o nā mea refractory:nā mea kūpaʻa alkaline; nā mea kūpaʻa silicon alumini; nā mea kūpaʻa ʻano ʻole; nā mea kūpaʻa wela insulation; nā mea kūpaʻa kūikawā; nā mea kūpaʻa hana no nā ʻōnaehana hoʻolei mau.
Nā Nīnau i Nīnau Pinepine ʻia
Pono kōkua? E kipa aku i kā mākou mau kahua kākoʻo no nā pane i kāu mau nīnau!
He mea hana maoli mākou, ua loea kā mākou hale hana i ka hana ʻana i nā mea refractory no nā makahiki he 30 a ʻoi. Hoʻohiki mākou e hāʻawi i ke kumukūʻai maikaʻi loa, ka lawelawe mua a me ka lawelawe ma hope o ke kūʻai aku.
No kēlā me kēia kaʻina hana, loaʻa iā RBT kahi ʻōnaehana QC piha no ka hoʻohuihui kemika a me nā waiwai kino. A e hoʻāʻo mākou i nā waiwai, a e hoʻouna ʻia ka palapala hōʻoia maikaʻi me nā waiwai. Inā he mau koi kūikawā kāu, e hoʻāʻo mākou i ka maikaʻi loa e hoʻokō iā lākou.
Ma muli o ka nui, ʻokoʻa ka manawa hoʻouna. Akā ke hoʻohiki nei mākou e hoʻouna koke me ka maikaʻi i hōʻoia ʻia.
ʻOiaʻiʻo, hāʻawi mākou i nā laʻana manuahi.
ʻAe, ʻoiaʻiʻo, ua ʻoluʻolu ʻia ʻoe e kipa i ka hui ʻo RBT a me kā mākou huahana.
ʻAʻohe palena, hiki iā mākou ke hāʻawi i ka manaʻo maikaʻi loa a me ka hoʻonā e like me kou kūlana.
Ua hana mākou i nā mea refractory no nā makahiki he 30 a ʻoi, loaʻa iā mākou ke kākoʻo loea ikaika a me ka ʻike waiwai, hiki iā mākou ke kōkua i nā mea kūʻai aku e hoʻolālā i nā kilns like ʻole a hāʻawi i ka lawelawe hoʻokahi.
