ʻO ka piliki kalapona Alumina C kahi ʻano mea refractory hui kalapona i hana ʻia me nā mea alumina a me ke kalapona, i kekahi manawa i hui pū ʻia me ka silicon carbide, metala silicon a me nā mea hoʻopili organik ʻē aʻe, e like me ka resin. Loaʻa i nā ʻano piliki kalapona alumina ke ahi nā piliki paheʻe kalapona alumini, nā piliki nozzle hoʻolei, nā piliki kalapona alumini kūpaʻa alkali a me nā piliki kalapona alumini umu pahū. ʻO nā hiʻohiʻona o ka piliki kalapona alumina refractory he kūpaʻa ikaika i ka corrosion, ke kūpaʻa haʻalulu wela maikaʻi, ka ikaika kiʻekiʻe a me ka conductivity wela kiʻekiʻe.
Kaʻina Hana Piliki Kalapona Alumina
Hana ʻia ka piliki kalapona alumina ma ka hoʻohana ʻana i ka clinker bauxite papa kūikawā, corundum, graphite a me ka mid alumina ma ke ʻano he mau mea maka nui, i hui pū ʻia me kekahi mau ʻano mea hoʻohui pauka maikaʻi loa. ʻO ke kaʻina hana o ka piliki kalapona alumina refractory ka hoʻohui ʻana i ka Aluminum oxide, carbonaceous, silicon powder materials a me nā mea liʻiliʻi o nā mea maka ʻē aʻe i ka mea maka, a laila e hoʻohana i ka asphalt, kahi mea hoʻopaʻa, resin a i ʻole ma hope o nā mea hoʻohui, kāwili ʻana, kaomi ʻana i ke ʻano, ma kahi o 1300 ℃ sintering i ka lewa hoʻemi.
Nā Hiʻohiʻona o ka Piliki Kalapona Alumina
- kūpaʻa ikaika i ka pala,
- kūpaʻa haʻalulu wela maikaʻi,
- ikaika kiʻekiʻe,
- ka hoʻokele wela kiʻekiʻe.
Ka Hoʻokaʻawale ʻana o nā Piliki Kalapona Alumina
Hiki ke hoʻokaʻawale ʻia nā piliki kalapona alumina i ʻelua mau ʻano, nā piliki kalapona magnesia alumina a me nā piliki kalapona magnesia alumina.
ʻO ka pōhaku kalapona magnesia alumina, me ka magnesite kiʻekiʻe, corundum, spinel a me ka graphite ma ke ʻano he mau mea maka, i hoʻopaʻa ʻia e ka resin, ua hōʻailona ʻia e ke kūpaʻa slag maikaʻi.
ʻO ka pōhaku kalapona alumina magnesia, me ke kumu kūʻai bauxite kiʻekiʻe, corundum, spinel, magnesite maʻemaʻe kiʻekiʻe a me ka graphite, i hoʻopaʻa ʻia e ka resin, hōʻailona ʻia e ke kūpaʻa i ka ʻino a me ka corrosion, ke kūpaʻa spalling.
