Kumukūʻai i ʻōlelo ʻia no ka Refractory High Alumina Brick (Al2O3 48% ~ 99%)
I kēia manawa, he nui kā mākou mau limahana hana kupaianaha i ʻoi aku ka maikaʻi ma ka hoʻolaha ʻana, QC, a me ka hana ʻana me nā ʻano pilikia like ʻole i loko o ka ʻōnaehana hana noʻO ka pōhaku Alumina a me ka pōhaku Refractory, No ka hana ʻana i nā waiwai hana hou aʻe, mālama i nā waiwai kiʻekiʻe a hoʻohou ʻaʻole wale i kā mākou waiwai kūʻai akā iā mākou iho i mea e hoʻomau ai iā mākou i mua o ka honua, a ʻo ka mea hope akā koʻikoʻi loa: e hoʻomāʻona i kēlā me kēia mea kūʻai aku i nā mea a pau a mākou e hāʻawi ai a e ulu ikaika pū. I mea e lanakila maoli ai, hoʻomaka ma aneʻi!
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.
