Nā Piliki Paʻakikī Alumina Kiʻekiʻe
ʻIke Huahana
Nā pōhaku alumini kiʻekiʻee pili ana i ka ʻike alumina ma mua o 48% o kahi mea refractory kūlike ʻole, e like me ka ʻike alumini like ʻole, i māhele nui ʻia i ʻekolu pae: Ⅰ(Al2O3≥75%); Ⅱ(60%≤Al2O3<75%); Ⅲ(48%≤Al2O3<60%). Hoʻokumu ʻia nā piliki alumina kiʻekiʻe a calcined mai ka bauxite a i ʻole nā mea maka ʻē aʻe me ka ʻike alumina kiʻekiʻe. Loaʻa iā lākou ke kūpaʻa wela kiʻekiʻe a me ka refractoriness ma luna o 1770 ℃, a he kūpaʻa slag maikaʻi a hoʻohana ʻia no ka uhi ʻana i ka EAF, nā umu hoʻoheheʻe aniani, nā umu rotary sima, a pēlā aku.
Nā hiʻohiʻona
1. Hana maikaʻi i ka mahana kiʻekiʻe
2. Kū'ē maika'i i ka spalling
3. Kūlana paʻa wela kiʻekiʻe (refractoriness ma luna o 1770 ℃)
4. Ke kūpaʻa maikaʻi ʻana i ka slag
5. Kū'ē maikaʻi loa i ka palaho waikawa a me ka alkali

Nā pōhaku alumina kiʻekiʻehoʻohana nui ʻia no VOD, AOD, nā umu pahū, nā umu pahū wela, EAF, nā umu reverberatory, a me nā uhi umu rotary. Eia kekahi, hoʻohana nui ʻia nā piliki alumina kiʻekiʻe e like me nā piliki nānā mālama wela ahi hāmama, nā plug no nā ʻōnaehana ninini, nā piliki nozzle, a pēlā aku.

ʻO Shandong Robert New Material Co., Ltd. Aia ma Zibo City, Shandong Province, Kina, kahi 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, a me ka inoa maikaʻi.Uhi kā mākou hale hana ma mua o 200 ʻeka a ʻo ka huahana makahiki o nā mea pale ʻino i hoʻohālikelike ʻia he 30000 tons a ʻo nā mea pale ʻino 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.
