ʻO ka piliki ahi silica alumina kahi ʻano mea refractory alumina silica, he mau hiʻohiʻona o ka refractoriness kiʻekiʻe ka piliki refractory alumina silicate, kūpaʻa maikaʻi i ka erosion a me ka ikaika kiʻekiʻe. Hoʻokomo pū ka piliki refractory aluminika silicate i nā ʻano piliki ahi he nui e like me ka piliki silica, ka piliki fireclay, ka piliki alumina kiʻekiʻe, ka piliki mullite a me ka piliki corundum. Hiki ke hoʻohana ʻia ka piliki ahi silica alumina no nā ʻano lako hana wela āpau.
Ka Hoʻokaʻawale ʻana o nā Piliki Ahi Alumina Silica
Wahi a ke ʻano o ka hoʻonui ʻana i ka ʻike mai SiO2 a i Al2O3, ua hoʻokaʻawale ʻia nā pōhaku ahi silicon alumini i nā ʻāpana penei:
Piliki silica: ʻoi aku ka nui o ka SiO2 ma mua o 93%,
Piliki lepo: ʻo ka nui o Al2O3 he 30%-48%,
ʻOi aku ka nui o ka pōhaku alumina kiʻekiʻe ma mua o 48% o ka ʻike o Al2O3,
ʻO ka pōhaku Mullite: ʻoi aku ka nui o ka ʻike o Al2O3 ma mua o 72% a like paha, a ʻoi aku ka nui o ka ʻike o SiO2 ma mua o 28% a like paha.
Piliki Corundum: ʻoi aku ka nui o Al2O3 ma mua o 90%.
Ka hoʻohana ʻana o ka Alumina Silica Fire Brick
Hoʻohana nui ʻia ka piliki silica e hana i ka umu coke, ka umu aniani, ka umu seramika, ka umu calcination kalapona a ʻaʻole kūpono ia no ka hoʻohana ʻana i nā lako hoʻomehana me ka loli o ka mahana ma lalo o 600 ℃.
Hoʻohana mau ʻia ka piliki lepo i loko o ka umu pahū, ka mea hoʻomehana wela, ka umu hoʻomehana, ka paila mana, ka umu lime, ka umu rotary, ka umu seramika a me ka umu calcining.
Hoʻohana nui ʻia nā pōhaku alumina kiʻekiʻe i ka hana kila, ka ʻoihana metala non-ferrous a me nā ʻoihana ʻē aʻe.
Hoʻohana ʻia ka pōhaku Mullite i nā ʻano ʻoihana āpau i hoʻopaʻa ʻia i ka umu wela a me ke kākoʻo i ka ʻoihana metallurgical, ʻoihana petrochemical, ʻoihana mea kūkulu hale, ʻoihana seramika, a me ka ʻoihana mechanical.
Hiki ke hoʻohana ʻia nā piliki Corundum i loko o ka umu pahū, ka umu pahū wela, ka umu aniani a pēlā aku.
Nā hiʻohiʻona o ka Alumina Silica Fire Brick
- Kiʻekiʻe ka refractoriness,
- Kū'ē maika'i i ka ha'alulu wela,
- Ke kūpaʻa ikaika ʻana i ka ʻāʻī waikawa,
- Ikaika wela kiʻekiʻe,
- Ka helu hoʻonui wela haʻahaʻa,
- Ka hoʻokele wela kiʻekiʻe.

Mea Hana Piliki Ahi Alumina Silica
ʻO ka mea hana hana palepale RS kekahi o nā mea hana hana piliki palepale kiln alakaʻi i loea i ka ʻoki ʻana a me ke ʻano ʻana i nā piliki palepale e like me ka makemake o ka mea kūʻai aku, hiki ke hana i nā piliki ahi alumina silica kiʻekiʻe nāu.
