Nā Hale Hana Hale no 48% -80% Al2O3 Refractory High Alumina Brick no ka Hoʻomehana ʻana i ka Furnace Hot Sell
ʻO kā mākou mau pono hana i lako pono ʻia a me ka hoʻokele kūlana kiʻekiʻe loa ma nā pae āpau o ka hana ʻana e hiki ai iā mākou ke hōʻoia i ka ʻoluʻolu o ka mea kūʻai aku noʻO ka pōhaku Alumina kiʻekiʻe a me ka pōhaku Alumina kiʻekiʻe refractory, i kēia manawa, loaʻa iā mākou nā kūʻai aku pūnaewele i ka lā holoʻokoʻa e hōʻoia i ka lawelawe mua a me ka lawelawe ma hope o ke kūʻai aku i ka manawa kūpono. Me kēia mau kākoʻo a pau, hiki iā mākou ke lawelawe i kēlā me kēia mea kūʻai aku me ka huahana maikaʻi a me ka hoʻouna ʻana i ka manawa kūpono me ke kuleana nui. Ma ke ʻano he ʻoihana ʻōpio e ulu nei, ʻaʻole paha mākou ka mea maikaʻi loa, akā ke hoʻāʻo nei mākou i ka mea maikaʻi loa e lilo i hoa maikaʻi nou.
Nā pōhaku lepo paʻa alumina kiʻekiʻehe ʻano mea refractory aluminosilicate me ka alumina ma ke ʻano he mea nui. Me ka ʻike alumina ma mua o 48%, ua hoʻokaʻawale ʻia lākou he mau mea refractory kūlike, i hana ʻia mai ka bauxite a i ʻole nā mea maka ʻē aʻe me ka ʻike alumina kiʻekiʻe ma o ka hoʻoheheʻe ʻana a me ka calcination.
Hoʻokaʻawale ʻana:
Ma muli o ka nui o ka alumina, ua māhele ʻia lākou i ʻekolu mau papa:
Papa 1: nā piliki alumina kiʻekiʻe (ʻike ʻia ka Al₂O₃ > 75%)
Papa 2: nā piliki alumina kiʻekiʻe (ʻike Al₂O₃: 60% ~ 75%)
Papa 3: nā piliki alumina kiʻekiʻe (ʻike Al₂O₃: 48% ~ 60%)
Nā ʻAno Piliki Maʻamau a me nā Koho Maʻamau:
Nā piliki maʻamau, nā piliki wedge, nā piliki checker, nā piliki piʻo, nā piliki heleuma, nā piliki hoʻokaʻawale honua, nā piliki ʻewalu ʻākau, nā piliki hoʻolei, a me nā ʻano maʻamau e like me nā kiʻi / laʻana a ka mea kūʻai aku.
Nā Waiwai Kino-kemika:
1. Kūpaʻa ʻole
Hiki iā ia ke kū i nā mahana kiʻekiʻe ma luna o 1770 ℃, ma ke ʻano maʻamau mai 1750 ℃ a i 1790 ℃. Hoʻonui ka refractoriness me ka piʻi ʻana o ka nui o ka alumina.
2. Ka Mahana Hoʻoluʻolu o ka Ukana
ʻO ka maʻamau he 1420 ℃ ~ 1530 ℃. Ma muli o ke kiʻekiʻe o ka ʻike alumina, ka haʻahaʻa o ka haumia a me ka liʻiliʻi o ka hoʻokumu ʻia ʻana o ka pae aniani fusible, ʻoi aku ke kiʻekiʻe o kona mahana palupalu ukana ma mua o nā piliki lepo ahi.
3. Ikaika Hoʻopaʻa Anuanu
ʻO ka ikaika kaomi anu o nā piliki alumina kiʻekiʻe o ka Papa 1 (LZ-80) he ≥ 70 MPa, ʻoiai ʻo ka ikaika o nā piliki alumina kiʻekiʻe o ka Papa 3 (LZ-48) he ≥ 40 MPa.
4. Ke kū'ē ʻana i ka slag
ʻOi aku ka nāwaliwali o nā piliki alumina kiʻekiʻe ma mua o nā mea kūpaʻa kūlohelohe, hiki ke pale aku i ka ʻino ʻana o nā ʻōpala waikawa a me nā alkaline, akā ʻoi aku ka nāwaliwali o ko lākou kūpaʻa ʻana i nā ʻōpala alkaline ma mua o nā ʻōpala waikawa.
5. Porosity ʻike ʻia
ʻO ka porosity maopopo o nā piliki alumina kiʻekiʻe o ka Papa 1 he ≤ 21%, a ʻo ka porosity o nā piliki alumina kiʻekiʻe o ka Papa 3 he ≤ 22%.

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.
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.
