China Standard Size Alumina Silica Brick No ka hale hana ʻo Sodium Silicate Furnace a me nā mea hana | ʻO Rongsheng

ʻO ka wehewehe pōkole:

ʻO ka alumina silica pōhaku ahi i loaʻa iā Al2O3 a me SiO2 mau mea refractory, alumina silica brick he moʻo o ka alumini silicon refractory brick. Loaʻa i nā ʻano hana like ʻole o ka alumini silicon series firebrick a noho i kahi kūlana koʻikoʻi i ka ʻoihana noi refractory. ʻOi aku ka nui o nā ʻāpana alumina silicate ma mua o 40% o nā huahana refractory holoʻokoʻa.

ʻO ka alumina silica ahi pōhaku kahi ʻano o ka alumina silica refractory mea, ʻo ka alumina silicate refractory brick he mau hiʻohiʻona o ka refractoriness kiʻekiʻe, ke kūpaʻa maikaʻi a me ka ikaika kiʻekiʻe. ʻO ka alumini silicate refractory brick he nui nā ʻano mea ahi e like me ka silica brick, fireclay brick, High alumina brick, mullite brick a me corundum Brick. Hiki ke hoʻohana ʻia nā pōhaku ahi alumina silica no nā ʻano mea wela.

Hoʻokaʻawale ʻia ʻo Alumina Silica Fire Brick

E like me ke kauoha o ka hoʻonui ʻana i ka ʻike mai SiO2 a i Al2O3, ua hoʻokaʻawale ʻia ka alumini silikon ahi brick i loko o nā ʻāpana aʻe.

Silica brick: ʻoi aku ka nui o ka SiO2 ma mua o 93%,

Pilikia pālolo: ʻo ka ʻike o Al2O3 he 30% -48%,

Pilikia alumina kiʻekiʻe: ʻoi aku ka nui o ka Al2O3 ma mua o 48%,

Mullite brick: ʻoi aku ka nui o ka ʻike o Al2O3 ma mua a i ʻole like me 72%, a ʻoi aku ka nui o ka ʻike o SiO2 ma mua o 28%,

Pilikia Corundum: ʻoi aku ka nui o Al2O3 ma mua o 90%.

Hoʻohana ʻia ʻo Alumina Silica Fire Brick

Hoʻohana nui ʻia ka silica brick no ke kūkulu ʻana i ka umu coke, kiln aniani, kiln ceramic, carbon calcinations furnace a ʻaʻole kūpono e hoʻohana ʻia i nā mea hoʻomehana me ka piʻi ʻana o ka mahana ma lalo o 600 ℃.

Hoʻohana mau ʻia ka pālolo pālolo i loko o ka umu ahi, ka mea hoʻoheheʻe wela, ka umu hoʻomehana, ka paila mana, ka lime kiln, rotary kiln, ceramic kiln a me ka calcining kiln.

Hoʻohana nui ʻia nā pōhaku alumina kiʻekiʻe i ka hana kila, ʻoihana metala non-ferrous a me nā ʻoihana ʻē aʻe.

Hoʻohana ʻia ʻo Mullite brick i nā ʻano ʻano umu ahi wela wela a me ka pale ʻana i ka ʻoihana metallurgical, ʻoihana petrochemical, ʻoihana hale kūkulu, ʻoihana seramika, a me nā ʻoihana mīkini.

Hiki ke hoʻohana ʻia nā pōhaku Corundum i ka umu ahi, ka umu wela wela, ka umu aniani a me nā mea ʻē aʻe.

Nā hiʻohiʻona piliki ahi alumina silica

  • ʻO ka refractoriness kiʻekiʻe,
  • Kūleʻa haʻalulu maikaʻi,
  • ʻO ke kūpaʻa ʻana o ka ʻakika ikaika,
  • ikaika wela wela,
  • Haʻahaʻa hoʻonui hoʻonui wela,
  • Kiʻekiʻe thermal conductivity.

Mea Hana Piliki Ahi Alumina Silica

ʻO RS refractory mea hana ma ke ʻano kekahi o ka mea hana kiln refractory bricks koʻikoʻi i ka ʻoki ʻana a me ka hoʻohua ʻana i nā brick refractory e like me ka koi o ka mea kūʻai aku, hiki iā ia ke hana i nā pōhaku ahi alumina silica kiʻekiʻe no ʻoe.
