Nā Piliki ʻAlanui Alumina
Nā pōhaku lepo aluminaua hana ʻia mai nā mea maka alumina kiʻekiʻe ma o ka hoʻohālikelike paʻa, ke kaomi ʻana i ke kaomi kiʻekiʻe a me ke kuni ʻana i ka mahana kiʻekiʻe. Me ka nui o ka Al₂O₃, ke ʻano like a me ka hana paʻa, hoʻohana nui ʻia lākou ma ke ʻano he mau mea uhi i nā wahi ʻoihana wela kiʻekiʻe, ʻaʻahu kiʻekiʻe a me ka ʻino.
Hāʻawi kā mākou mau piliki uhi alumina i ka palekana maikaʻi loa no nā umu ʻoihana, nā umu, nā paipu, nā cyclones, nā chutes a me nā lako hana, e hōʻemi pono ana i ke komo ʻana, ka pala a me ka pohō wela, a e hoʻomaikaʻi nui ana i ke ola lawelawe o nā lako a me ka pono hana.
Kākoʻo mākou i nā ana maʻamau, nā ʻano kūikawā a me nā māka alumina like ʻole e hoʻokō i kāu mau koi papahana kikoʻī.
Nā Pōmaikaʻi Koʻikoʻi:
1. Ke kū'ē ʻana i ka mahana kiʻekiʻe
Hiki ke kū i ka mahana hana lōʻihi a hiki i 1350°C–1750°C, ma muli o ke ʻano.
2. Ke kūpaʻa ʻana i ka ʻaʻahu nui
ʻO ka paʻakikī kiʻekiʻe a me ka helu abrasion haʻahaʻa e kūʻē pono i ka holoi ʻana a me ka friction mea.
3. Ke kūpaʻa ikaika i ka palaho
ʻO ke kūpaʻa maikaʻi i ka waikawa, alkali, slag hoʻoheheʻe ʻia, ka lepo a me ka pala kemika.
4. Paʻa Mahana Maikaʻi
ʻO ka nui o ka hoʻonui wela haʻahaʻa, ke kūpaʻa haʻalulu wela ikaika, ka emi ʻana o ka nahā.
5. Ola lawelawe lōʻihi
E hōʻemi i ke alapine (frequency) o ka mālama ʻana, e hoʻemi i ka manawa downtime a me ke kumukūʻai hana holoʻokoʻa.
6. Hoʻokomo maʻalahi
Loaʻa nā nui maʻamau a me nā nui maʻamau no ke kūkulu pono ʻana a me ka hoʻololi ʻana.
