ʻO ka alumina Ccarbon brick kahi ʻano mea hoʻohui kalapona refractory i hana ʻia me ka alumina a me nā mea kalapona, i kekahi manawa i hui pū ʻia me ka silicon carbide, metala silika a me nā mea paʻa ʻē aʻe, e like me ka resin. ʻO nā ʻano like ʻole alumina kalapona kalapona he alumini kalapona paheʻe pōhaku lepo, hoʻolei nozzle brick, alkali kūpaʻa alumini kalapona pōhaku lepo a me ka umu ahi alumini kalapona pōhaku lepo. ʻO ka alumina carbon refractory brick hiʻohiʻona he ikaika ka corrosion kū'ē, maikaʻi thermal haʻalulu kūpaʻa, kiʻekiʻe ikaika a kiʻekiʻe thermal conductivity.
Kaʻina Alumina Carbon Brick
Hana ʻia ʻo Alumina carbon brick ma ka hoʻohana ʻana i ka clinker bauxite grade kūikawā, corundum, graphite a me mid alumina ma ke ʻano he kumu kumu, i hui pū ʻia me nā ʻano mea hoʻohui pauka super fine. ʻO ke kaʻina hana o ka alumina carbon refractory brick ke hoʻohui nei i ka Aluminum oxide, carbonaceous, silicon powder material a me nā mea liʻiliʻi o nā mea maka i ka mea maka, a laila e hoʻohana i ka asphalt, kahi mea hoʻopaʻa, resin a ma hope o nā meaʻai, hui ʻana, kaomi ʻana, ma kahi o 1300 ℃ sintering. i ka hoemi ana i ka lewa.
Nā hiʻohiʻona o Alumina Carbon Brick
- ikaika i ka corrosion,
- paʻa haʻalulu maikaʻi,
- ikaika kiʻekiʻe,
- kiʻekiʻe thermal conductivity.
Hoʻokaʻawale ʻana i ka Alumina Carbon Brick
Hiki ke hoʻokaʻawale ʻia nā ʻāpana kalapona alumina i ʻelua papa, ʻo ka magnesia alumina carbon brick a me ka alumina magnesia carbon brick.
ʻO ka pōhaku lepo kalapona Magnesia alumina, me ka magnesite kiʻekiʻe, corundum, spinel a me ka graphite e like me nā mea maka, i hoʻopaʻa ʻia e ka resin, ua ʻike ʻia e ke kūpaʻa maikaʻi.
ʻO ka alumina magnesia carbon brick, me ka bauxite kiʻekiʻe, corundum, spinel, magnesite maʻemaʻe kiʻekiʻe a me ka graphite e like me nā mea maka, i hoʻopaʻa ʻia e ka resin, ua ʻike ʻia e ka erosion a me ka corrosion resistance, spalling resistance.
