Kina Kumukūʻai haʻahaʻa Lz-65 High-Alumina Refractory Brick Fused Cast Glass Furnace
Mai kona hoʻomaka ʻana, manaʻo mau kā mākou ʻoihana i ka maikaʻi o nā huahana ma ke ʻano he ola o ka ʻoihana, hoʻomaikaʻi mau i ka ʻenehana hana, hoʻomaikaʻi i ka maikaʻi o ka huahana a hoʻoikaika pinepine i ka hoʻokele maikaʻi piha o ka hui, e like me ke kūlana aupuni ISO 9001: 2000 noBrick a me nā Brick Alumina Kiʻekiʻe, I mea e hoʻokō ai i nā koi o ka mākeke a me ka hoʻomohala lōʻihi, ke kūkulu ʻia nei kahi hale hana hou he 150,000 mika kuea, kahi e hoʻohana ʻia ai i ka makahiki 2014. A laila, e loaʻa iā mākou kahi mana hana nui. ʻOiaʻiʻo, e hoʻomau mākou i ka hoʻomaikaʻi ʻana i ka ʻōnaehana lawelawe e hoʻokō ai i nā koi o nā mea kūʻai aku, e lawe mai ana i ke olakino, ka hauʻoli a me ka nani i nā mea āpau.
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.
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.
