ʻO ka Bauxite i hoʻopaʻa ʻia
ʻIke Huahana
calcined bauxiteʻO ia kekahi o nā mea nui o ka aluminika. Loaʻa ʻia ka bauxite calcined rotary kiln ma ka calcining ʻana i ka bauxite papa kiʻekiʻe ma ka wela kiʻekiʻe (mai 850ºC a 1600ºC) i loko o ka rotary kiln. Hoʻopau kēia i ka makū ma laila e hoʻonui ai i ka ʻike alumina.
Hoʻokaʻawale ʻia ka bauxite calcined i ka bauxite kūikawā, ka bauxite papa mua, ka bauxite papa lua, a me ka bauxite papa kolu e like me ka ʻike o nā mea haumia e like me Al2O3, Fe2O3, a me SiO2, a me ka nui o ka clinker a hoʻoheheʻe wai. I mea e ʻoi aku ka maikaʻi o ka kūʻai ʻana o nā mea kūʻai aku, hoʻohana kā mākou hale hana i ka ʻike Al2o3 o ka bauxite ma ke ʻano he lepili e hoʻokaʻawale iā ia i 55, 65, 70, 75, 80, 85, 88 a me 90.
Ma waho aʻe, ma o ka calcination, e hoʻomaikaʻi ʻia ka density a me ke kūpaʻa refractory i nā pae like ʻole. Hiki ke hoʻonui nui ʻia ka pae o ka bauxite.
Hiki ke hana ʻia ka bauxite calcined i ke one bauxite a me ka pauka bauxite o nā ʻāpana like ʻole, hiki ke hoʻohana pololei ʻia ia mau mea ʻelua e like me ke one refractory. He kūlana kiʻekiʻe loa ia ma ke kahua o nā mea refractory.

2. Hoʻolei pololei / hoʻolei kālā: Hiki ke hana ʻia nā uku hoʻopaʻi Bauxite i loko o ka poni no ka hoʻolei pololei ʻana.
3. Hoʻopaʻa ʻia:
(1) Hiki i ka refractoriness o ka bauxite kiʻekiʻe ke hiki i 1780 ° C me ka paʻa kemika maikaʻi a me ka hana mechanical.
(2) Aluminum silicate refractory fiber: hiki ke hoʻoheheʻe ʻia ka bauxite kiʻekiʻe i ka umu ahi arc, e hana ana i ka alumini silicate refractory fiber, hiki ke hana ʻia i loko o ka pākeke fiber ceramic, pā, lole etc.
(3) Ka hui ʻana i ka magnesia a me ka bauxite grog me nā mea hoʻopaʻa no ka ninini ʻana i ka ipu hao i hoʻoheheʻe ʻia no ka ʻoi aku ka maikaʻi o ka uhi ʻana.

Shandong Robert New Material Co., Ltd.Aia ma Zibo City, Shandong Province, Kina, kahi kumu hana hana refractory. He ʻoihana hou mākou e hoʻohui i ka noiʻi a me ka hoʻomohala ʻana, ka hana ʻana, ke kūʻai aku, ka hoʻolālā kiln a me ke kūkulu ʻana, ʻenehana, a me nā mea refractory hoʻokuʻu aku. Loaʻa iā mākou nā lako piha, nā ʻenehana holomua, ka ikaika ʻenehana ikaika, ka maikaʻi o ka huahana maikaʻi, a me ka inoa maikaʻi. Uhi kā mākou hale hana ma luna o 200 mau ʻeka a ʻo ka puka makahiki o nā mea refractory i hoʻohālikelike ʻia ma kahi o 30000 tons a me nā mea refractory unshaped he 12000 tons.
ʻO kā mākou huahana nui o nā mea refractory:nā mea pale alkaline; aluminika silika refractory mea; nā mea refractory ʻaʻole i hoʻohālikelike ʻia; insulation thermal refractory mea; nā mea refractory kūikawā; nā mea refractory hana no nā ʻōnaehana hoʻolei mau.
Nīnau pinepine
Pono kōkua? E ʻoluʻolu e kipa i kā mākou hui 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. Hoʻohiki mākou e hāʻawi i ke kumukūʻai maikaʻi loa, ʻoi aku ka maikaʻi ma mua o ke kūʻai aku a ma hope o ke kūʻai aku.
No kēlā me kēia kaʻina hana, loaʻa iā RBT kahi ʻōnaehana QC piha no ka haku melemele a me nā waiwai kino. A e hoʻāʻo mākou i nā waiwai, a e hoʻouna ʻia ka palapala hōʻoia me nā waiwai. Inā loaʻa iā ʻoe nā koi kūikawā, e hoʻāʻo mākou i ka maikaʻi loa e hoʻokipa iā lākou.
Ma muli o ka nui, ʻokoʻa kā mākou manawa lawe. Akā ke hoʻohiki nei mākou e hoʻouna koke aku me ka maikaʻi i hōʻoia ʻia.
ʻOiaʻiʻo, hāʻawi mākou i nā hōʻailona manuahi.
ʻAe, ʻoiaʻiʻo, ʻoluʻolu ʻoe e kipa i ka hui RBT a me kā mākou huahana.
ʻAʻohe palena, hiki iā mākou ke hāʻawi i ka manaʻo maikaʻi loa a me ka hopena e like me kou kūlana.
Ua hana mākou i nā mea refractory ma mua o 30 mau makahiki, loaʻa iā mākou ke kākoʻo ʻenehana ikaika a me ka ʻike waiwai, hiki iā mākou ke kōkua i nā mea kūʻai aku e hoʻolālā i nā kiln like ʻole a hāʻawi i ka lawelawe hoʻokahi.
