Hana huahana:He ikaika kona kūpaʻa wela kiʻekiʻe, kūpaʻa haʻalulu wela maikaʻi loa, kūpaʻa ʻaʻahu, kūpaʻa i ka corrosion kemika a me nā ʻano ʻē aʻe.
Nā hoʻohana nui:Hoʻohana nui ʻia i nā wahi hoʻololi o nā umu wili sima, nā umu decomposition, nā ʻauwai ea tertiary, a me nā lako hana thermal ʻē aʻe e pono ai ke kū'ē i ka haʻalulu thermal.
Nā hiʻohiʻona huahana:Ma ke ʻano he mea kumu o ka ʻoihana refractory, loaʻa i nā piliki alumina kiʻekiʻe nā ʻano o ke kūpaʻa kiʻekiʻe, ka mahana palupalu kiʻekiʻe (ma kahi o 1500°C), a me ke kūpaʻa maikaʻi i ka ʻino. Hoʻohana nui ʻia lākou i nā umu ʻoihana ma nā ʻoihana like ʻole. Eia nō naʻe, ma muli o ke kiʻekiʻe o ka pae corundum o nā piliki alumina kiʻekiʻe maʻamau, ʻoi aku ka nui o nā kristal pae corundum i nā huahana sintered, a he maʻalahi ka haki a me ka ʻili ʻana i ka wā e hālāwai ai me nā kūlana hoʻoluʻolu a me ka hoʻomehana wikiwiki. ʻO ke kūpaʻa haʻalulu wela ma lalo o nā kūlana hoʻoluʻolu wai 1100°C hiki ke hiki i 2-4 mau manawa. I loko o ka ʻōnaehana hana sima, ma muli o nā palena o ka mahana sintering a me nā koi hana no nā mea refractory e hoʻopili i ka ʻili o ka umu, hiki ke hoʻohana ʻia nā piliki alumina kiʻekiʻe ma kahi hoʻololi o ka umu rotary, ka huelo o ka umu a me ka preheater o ka umu decomposition.
ʻO nā piliki alumina kiʻekiʻe anti-spalling he mau piliki alumini kiʻekiʻe me nā waiwai anti-flaking i hana ʻia ma muli o ka clinker alumini kiʻekiʻe a hoʻohui ʻia me ZrO2 a i ʻole nā mea ʻē aʻe. Hiki iā lākou ke puʻunaue ʻia i ʻelua mau ʻāpana, ʻo kekahi he mau piliki alumina kiʻekiʻe anti-flaking i loaʻa iā ZrO2, a ʻo kekahi ʻo ia ka ʻano mua he mau piliki alumina kiʻekiʻe anti-flaking ʻaʻohe ZrO2.
Hiki i nā piliki alumina kiʻekiʻe anti-spalling ke kū i nā ukana wela wela kiʻekiʻe, ʻaʻole e emi ka nui a loaʻa ka hoʻonui like, ʻaʻole e kolo a hiolo paha, loaʻa ka ikaika wela maʻamau kiʻekiʻe loa a me ka ikaika wela wela kiʻekiʻe, ka mahana palupalu kaumaha kiʻekiʻe, a loaʻa iā ia ke kūpaʻa wela maikaʻi. Hiki iā ia ke kū i ka hopena o nā loli wela koke a i ʻole ka hoʻomehana like ʻole, a ʻaʻole e haki a ʻili paha. ʻO ka ʻokoʻa ma waena o nā piliki alumina kiʻekiʻe anti-flaking i loaʻa iā ZrO2 a me nā piliki alumina kiʻekiʻe anti-flaking me ka ʻole o ZrO2 aia i kā lākou mau ʻano hana anti-flaking like ʻole. Hoʻohana nā piliki alumina kiʻekiʻe anti-flaking i loaʻa iā ZrO2 i nā mea zircon e hoʻohana i ke kūpaʻa corrosion maikaʻi loa. Kūʻē ʻo ZrO2 i ka erosion o ka sulfur-chlor-alkali. I ka manawa like, i nā mahana kiʻekiʻe, e hana ka SiO2 i loko o ka zircon i kahi hoʻololi ʻana o ka pae kristal mai cristobalite i kahi pae quartz, e hopena ana i kahi hopena hoʻonui nui, no laila e hōʻemi ana i ka pilikia o ka pale ʻana o ka sulfur-chlor-alkali. I ka manawa like, pale ia i ka spalling i ka wā wela a me ke anu; Hana ʻia nā piliki alumina kiʻekiʻe anti-flake ʻaʻohe ZrO2 ma ka hoʻohui ʻana i ka andalusite i nā piliki alumina kiʻekiʻe. Hoʻohana ʻia ka andalusite i loko o ka huahana no ka mulliteization lua i loko o ka umu sima. Hoʻopuka ia i kahi hopena micro-expansion hiki ʻole ke hoʻihoʻi ʻia i ʻole e emi ka huahana ke hoʻomaʻalili ʻia, e hoʻopau ana i ke kaumaha shrinkage a pale i ka ʻili ʻana o ke kino.
Ke hoʻohālikelike ʻia me nā piliki alumina kiʻekiʻe anti-spalling ʻaʻohe ZrO2, ʻoi aku ka maikaʻi o ke kūpaʻa ʻana o nā piliki alumina kiʻekiʻe anti-spalling i loaʻa iā ZrO2 i ke komo ʻana a me ka ʻino ʻana o nā ʻāpana sulfur, chlorine a me alkali, no laila he ʻoi aku ka maikaʻi o ko lākou mau waiwai anti-flaking. Eia nō naʻe, no ka mea he mea kakaikahi ʻo ZrO2, he pipiʻi ia, no laila ʻoi aku ke kiʻekiʻe o ke kumukūʻai.ʻO nā piliki alumina kiʻekiʻe anti-flakeing i loaʻa iā ZrO2 e hoʻohana wale ʻia ma ka ʻāpana hoʻololi o nā umu wili sima. ʻO nā piliki alumina kiʻekiʻe anti-flakeing i loaʻa ʻole iā ZrO2 e hoʻohana nui ʻia i nā umu palaho o nā laina hana sima.
