1. High alumina bricks refractory bricks i hana muaʻia mai ka alumina (Al2O3) a me nā mea'ē aʻe, i hoʻolālāʻia no nā mea wela kiʻekiʻe e like me nā kapuahi, nā kiln, a me nā reactors.
2.Processing: hoʻohana ʻia ka bauxite ma ke ʻano he kumu maka, ua hoʻokaʻawale ʻia ka clinker e ka grading a kānana ʻia e wehe i ka hao, a ua hoʻomākaukau ʻia e ke ahi wela kiʻekiʻe.
3. Hana ʻia: Hana ʻia ma ka hui ʻana i nā mea maka (bauxite a i ʻole nā minela alumina kiʻekiʻe), e hoʻoheheʻe iā lākou i mau pōhaku lepo, a puhi ʻia i nā wela kiʻekiʻe. Hiki i ke kaʻina hana ke komo i nā mea hoʻohui like ʻole a me nā mea hoʻopili e hoʻokō i nā waiwai i makemake ʻia.
4. Koho ʻia nā pōhaku lepo alumina kiʻekiʻe no ko lākou kūpaʻa a me ka maikaʻi i nā kaiapuni koʻikoʻi, e hoʻolilo iā lākou i mea koʻikoʻi i nā noi ʻoihana wela kiʻekiʻe.

1. Kiʻekiʻe Refractoriness: Hiki iā lākou ke pale i nā wela kiʻekiʻe loa, e kūpono iā lākou no ka hoʻohanaʻana i nā kapuahi a me nā wahi wela kiʻekiʻe.

2. ʻO ke kūpaʻa wela maikaʻi loa: Mālama kēia mau pōhaku lepo i ko lākou kūpaʻa a me nā waiwai mechanical ma lalo o ka hoʻololi wikiwiki ʻana o ka mahana, e hōʻemi ana i ka pōʻino o ka haʻalulu wela.

3. Nā Waiwai Hoʻopili maikaʻi: ʻOiai ʻaʻole maikaʻi e like me nā mea hoʻokalakupua kūikawā, hāʻawi nā pōhaku alumina kiʻekiʻe i kahi pale e kūʻē i ka hoʻoili wela, e kōkua ana i ka mālama ʻana i ka ikehu ma nā noi ʻoihana.

4. Kū'ē i ka Corrosion a me ka Abrasion: Kū'ē lākou i kaʻinoʻino a me ka lole mechanical, e hoʻolōʻihi i ko lākou ola i nā kūlana hana paʻakikī.

5. Haʻahaʻa Thermal Conductivity: Ke kōkua nei kēia waiwai e hōʻemi i ka lilo ʻana o ka wela a mālama i nā kiʻi wela maʻamau i loko o ka lining refractory.

Ma keʻano holoʻokoʻa, waiwai nui nā pōhaku alumina kiʻekiʻe no ko lākou kūpaʻa, hilinaʻi, a me ka hiki ke kū i nā kūlana koʻikoʻi i nā kaʻina hana ʻenehana.
