Hana huahana:Loaʻa iā ia ka paʻa o ka leo wela kiʻekiʻe, ke kūpaʻa haʻalulu maikaʻi loa, ka pale ʻana i ke aahu, ke kūpaʻa corrosion a me nā ʻano ʻē aʻe.
Hoʻohana nui:Hoʻohana nui ʻia i nā ʻāpana hoʻololi o nā kiln rotary sima, nā kapuahi decomposition, nā ʻauwaʻa ea tertiary, a me nā mea wela ʻē aʻe e pono ai ke kū ʻana o ka haʻalulu wela.
Nā hiʻohiʻona huahana:Ma ke ʻano he kumu kumu o ka ʻoihana refractory, loaʻa i nā pōhaku alumina kiʻekiʻe nā hiʻohiʻona o ka refractoriness kiʻekiʻe, ʻoi aku ka kiʻekiʻe o ka haʻahaʻa haʻahaʻa haʻahaʻa (ma kahi o 1500 ° C), a me ke kūpaʻa maikaʻi. Hoʻohana nui ʻia lākou i nā kiln ʻoihana i nā ʻoihana like ʻole. Eia nō naʻe, ma muli o ke kiʻekiʻe o ka ʻāpana corundum o nā pōhaku alumina kiʻekiʻe, ʻoi aku ka nui o nā kristal corundum i loko o nā huahana i hoʻopaʻa ʻia, a ʻoi aku ka maʻa a me ka ʻili ʻana i ka wā e hālāwai ai me ka wikiwiki a me ka hoʻomehana ʻana. ʻO ke kūpaʻa haʻalulu ma lalo o 1100 ° C nā kūlana hoʻoluʻu wai hiki ke hiki i 2-4 mau manawa. Ma ka ʻōnaehana hana sima, ma muli o ka sintering palena wela a me nā koi hana no nā mea refractory e pili i ka ʻili kiln, hiki ke hoʻohana wale ʻia nā pōhaku alumina kiʻekiʻe ma ka wahi hoʻololi o ka rotary kiln, ka huelo kiln a me ka preheater o ka umu decomposition. .
ʻO nā pōhaku alumina kiʻekiʻe anti-spalling he mau pōhaku alumina kiʻekiʻe me nā waiwai anti-fllaking i hanaʻia ma muli o ka clinker alumina kiʻekiʻe a hoʻohuiʻia me ZrO2 a iʻole nā mea'ē aʻe. Hiki iā lākou ke hoʻokaʻawale ʻia i ʻelua mau ʻāpana, ʻo kekahi he anti-fllaking high-alumina bricks i loaʻa ZrO2, a ʻo kekahi ʻO ka ʻano mua he anti-fllaking alumina kiʻekiʻe alumina i loaʻa ʻole ZrO2.
Hiki i nā pōhaku lepo alumina anti-spalling ke kū'ē i nā kaumaha wela wela,ʻaʻole e emi i ka nui a me ka hoʻonui likeʻole,ʻaʻole e kolo a hāʻule paha, loaʻa ka ikaika wela maʻamau a me ka ikaika wela wela, ka wela hoʻoluʻu haʻahaʻa kiʻekiʻe, a loaʻa i ka wela maikaʻi. Hiki iā ia ke pale i ka hopena o ka hoʻololi koke ʻana o ka mahana a i ʻole ka wela ʻole, a ʻaʻole e pohā a ʻili paha. ʻO ka ʻokoʻa ma waena o nā pōhaku alumina kiʻekiʻe anti-fllaking i loaʻa nā ZrO2 a me nā pōhaku alumina kiʻekiʻe anti-fllaking me ka ʻole o ZrO2 aia i loko o kā lākou mau hana anti-fllaking like ʻole. ZrO2-i loko o ka anti-fllaking kiʻekiʻe alumina bricks hoʻohana i nā mea zircon e hoʻohana i ka hoʻohana ʻana i ke kūpaʻa corrosion maikaʻi loa. Kūʻē ʻo ZrO2 i ka ʻānai ʻana o ka sulfur-chlor-alkali. I ka manawa like, ma nā wela kiʻekiʻe, e hoʻololi ʻia ka SiO2 i loko o ka zircon i ka hoʻololi ʻana i ka māhele aniani mai ka cristobalite a i kahi quartz, e hopena i kekahi hopena hoʻonui nui, no laila e hōʻemi ana i ka hopena o ka pale ʻana i ka sulfur-chlor-alkali. I ka manawa like, pale ia i ka spalling i ka wā wela a me ke anu; ʻO nā pōhaku lepo alumina kiʻekiʻe anti-fllaking i loaʻa ʻole ZrO2 e hana ʻia ma ka hoʻohui ʻana i ka andalusite i nā pōhaku alumina kiʻekiʻe. Hoʻohana ʻia ka andalusite i loko o ka huahana no ka mulliteization lua i ka kiln sima. Hoʻopuka ia i kahi hopena micro-expansion hiki ʻole ke hoʻololi ʻole ʻia ka huahana i ka wā e hoʻomaha ai, e hoʻopau ana i ke koʻikoʻi shrinkage a pale i ka peeling structural.
Ke hoʻohālikelikeʻia me nā pōhaku lepo kiʻekiʻe-alumina anti-spalling i loaʻa ʻole ZrO2, ʻoi aku ka maikaʻi o ke kūʻē ʻana i nā ʻāpana anti-flaking anti-spalling i ke komo ʻana a me ka erosion o ka sulfur, chlorine a me nā mea alkali, no laila ua ʻoi aku ka maikaʻi o nā waiwai anti-fllaking. Eia naʻe, no ka mea he mea laha ʻole ʻo ZrO2, ʻoi aku ke kumukūʻai, no laila ʻoi aku ka kiʻekiʻe o ke kumukūʻai a me ke kumukūʻai.Hoʻohana wale ʻia nā pōhaku kiʻekiʻe alumina anti-fllaking i loaʻa iā ZrO2 i ka wahi hoʻololi o nā kiln rotary sima. Hoʻohana nui ʻia nā pōhaku lepo kiʻekiʻe alumina anti-fllaking ʻaʻole ZrO2 i nā kapuahi decomposition o nā laina hana sima.
