Hana ʻia nā piliki alumina kiʻekiʻe me ke koho ʻia ʻana o ka bauxite chamotte ma ke ʻano he mea maka nui, i puhi ʻia ma 1450-1470°C ma o ke kaʻina hana holomua me ka kaohi maikaʻi. Hana ʻia nā Piliki Ahi Alumina Kiʻekiʻe me ka alumina a i ʻole nā mea maka ʻē aʻe i loaʻa ka nui o ka alumina ma o ka hoʻoheheʻe ʻana a me ke ahi ʻana. Ma muli o kona waiwai kūpaʻa kūlike ʻole, hiki i ka alumina kūpaʻa ke kū'ē i ke kūpaʻa ʻana i ka ʻōpala waikawa.
Kaʻina Hana Piliki Alumina Kiʻekiʻe
E koho a kānana i ka chamotte no ka deironing ma mua o ka wāwahi ʻana, hiki ke hoʻomaikaʻi i ka maikaʻi o nā piliki alumina kiʻekiʻe. No ka mea, ʻoi aku ka nui o ka grog i loko o nā mea hoʻohui hiki ke hiki i ka 90 ~ 95%. E koho a kānana i ka deironing ma mua o ka wāwahi ʻana i ka grog.
ʻEkolu Papa o ka Brick Alumina Kiʻekiʻe
Wahi a nā ʻano ʻokoʻa o Al2O3, hiki ke hoʻokaʻawale ʻia nā piliki alumina kiʻekiʻe i ʻekolu mau papa ma Kina.
ʻOi aku ka nui o Al2O3 ma mua o 75% o nā pōhaku lepo alumina kiʻekiʻe o ka papa I.
ʻO ka nui o Al2O3 i loko o nā pōhaku lepo alumina kiʻekiʻe o ka papa II he 60 ~ 75%.
ʻO ka nui o Al2O3 i loko o nā pōhaku lepo alumina kiʻekiʻe papa III he 48 ~ 60%.
Nā Hiʻohiʻona o ka Brick Alumina Kiʻekiʻe
He mau hiʻohiʻona maikaʻi nā piliki alumina kiʻekiʻe e like me ka hana wela kiʻekiʻe, ka pale maikaʻi i ka pala a me ke komo ʻana, ka nui o ka nui, ka haʻahaʻa o ka hao, a me nā mea ʻē aʻe.

Noi ʻana i ka pōhaku lepo Alumina kiʻekiʻe
Hiki ke hoʻohana ʻia nā piliki alumina kiʻekiʻe i loko o ka umu pahū, ka umu pahū wela, ka umu uila. Hoʻohana ʻia nā piliki ahi alumina kiʻekiʻe i nā kahua o ka hao a me ke kila, nonferrous, aniani, sima, keramika, petrochemical, mīkini, paila, ʻoihana māmā, mana, a me ka ʻoihana koa, a pēlā aku.
