DEHA Series High Alumina Refractory Brick

1. Hoʻopaʻapaʻa
ʻOi aku ka kiʻekiʻe o ka refractoriness o CCEFIRE alumina kiʻekiʻe ma mua o nā pōhaku lepo refractory a me nā semi-silica brick, hiki i 1750 ~ 1790 ℃, he ʻano mea refractory kiʻekiʻe.

2. Hoʻouka i ka mahana hoʻoluʻu
No ka mea, he Al2O3 kiʻekiʻe nā huahana alumina, ʻoi aku ka liʻiliʻi o nā haumia, a me ke aniani fusible liʻiliʻi, ʻoi aku ka kiʻekiʻe o ka mahana hoʻoluʻu haʻahaʻa ma mua o nā pōhaku lepo, akā no ka hana ʻole ʻana o nā kristal mullite i kahi ʻano pūnaewele, ʻaʻole i like ke kiʻekiʻe o ka wela hoʻoluʻu haʻahaʻa e like me nā pōhaku silica.

3. Ke kū'ēʻana i ka slag
Loaʻa i nā pōhaku lepo alumina kiʻekiʻe CCEFIRE ʻo Al2O3, kokoke i ka mea refractory kū ʻole, no laila hiki iā lākou ke pale aku i ka erosion o ka ʻakika a me ka alkaline slag. Ma muli o ke ʻano o ka SiO2, ʻoi aku ka nāwaliwali o ka pale ʻana i ka slag alkaline ma mua o ka slag acid.

ʻO nā pōhaku lepo alumina kiʻekiʻe i hōʻike ʻia me ke kūpaʻa wela kiʻekiʻe, ka refractoriness kiʻekiʻe ma luna o 1770 degere, ke kūpaʻa slag maikaʻi, hoʻohana nui ʻia no ka umu uila ma luna, ka umu ahi, ka umu wela wela, ka ladle, ka hao i hoʻoheheʻe ʻia, ke kīʻaha sima, ke kīʻaha aniani a me nā mea wela wela. Hoʻohana nui ʻia i ka hana hao, hana kila, ʻoihana kemika, sima a me nā ʻoihana ʻē aʻe.
