Kiekie Alumina Refractory Bricks: Paʻa i nā kahu hilinaʻi o nā ʻoihana wela kiʻekiʻe

Ma ke kahua o nāʻoihana wela kiʻekiʻe, hoʻoholo pololei ka hana o nā mea i ka paʻa a me ka pono o ka hana.Kiʻekiʻe alumina refractory bricks, ʻoiai ʻo nā mea refractory kiʻekiʻe kiʻekiʻe i hana nui ʻia mai ka alumina bauxite kiʻekiʻe, ua lilo i mea koho maikaʻi loa no nā ʻoihana wela kiʻekiʻe me kā lākou hana koʻikoʻi, e mālama ana i ka hoʻomohala ʻana o ka metallurgy honua, nā mea kūkulu hale, kemika a me nā ʻoihana ʻē aʻe.​

ʻO nā pōmaikaʻi koʻikoʻi o nā brick refractory alumina kiʻekiʻe e loaʻa mai i kā lākou hana ʻokoʻa a me ka hana hana. Hana ʻia kēia mau pōhaku mai ke kiʻekiʻe-alumina bauxite clinker me kahi alumina ma lalo o 48% e like me ka aggregate, i hui pū ʻia me nā binders i nā ʻano like ʻole, a laila hana ʻia, maloʻo, a puhi ʻia i nā wela kiʻekiʻe. Loaʻa i nā pōhaku kiʻekiʻe alumina refractory ka refractoriness maikaʻi loa, hiki ke kū i nā wela kiʻekiʻe mai 1770 ° C a 1790 ° C. ʻOiai i loko o nā kaiapuni wela kiʻekiʻe loa, hiki iā lākou ke mālama i ka kūpaʻa o ke kūkulu ʻana, me ka pale maikaʻi ʻana i ka erosion o nā wela kiʻekiʻe ma nā mea hana. ʻO kā lākou haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa e hōʻoiaʻiʻo ʻaʻole lākou e hoʻololi i ka deformation a hāʻule i lalo o kekahi kaomi a me nā wela kiʻekiʻe, e hāʻawi ana i nā hōʻoia hilinaʻi no ka hana paʻa o nā mea wela wela. Eia kekahi, ʻoi aku ka maikaʻi o ke kūpaʻa ʻana o nā alumina refractory kiʻekiʻe, e hiki ai iā lākou ke mālama i ka hana paʻa i ka wā e hoʻololi pinepine ai ka mahana, e hōʻemi ana i ka haki ʻana a me ka spalling ma muli o ke kaumaha wela a hoʻonui i ko lākou ola lawelawe. He kūʻē ikaika nō hoʻi lākou i nā mea kemika like ʻole. Inā ʻo ia ka slag i loko o ke kaʻina hana metala a i ʻole nā kinoea corrosive i ka hana kemika, paʻakikī ke hana ʻino nui iā lākou.​

Loaʻa i nā pōhaku kiʻekiʻe alumina refractory kahi ākea o nā noi. I loko o kaʻoihana metallurgical, he mau mea koʻikoʻi ia no ka uhiʻana o nā kapuahi hana kila, nā kapuahi hao, a me nā kapuahi hoʻomaha. Hiki iā lākou ke pale maikaʻi i ka hoʻoheheʻe ʻana o ke kila hoʻoheheʻe kiʻekiʻe a me ka slag, e hōʻoiaʻiʻo ana i ka holomua holomua o ke kaʻina hoʻoheheʻe a me ka hoʻomaikaʻi ʻana i ke ola lawelawe o nā mea hana a me ka hana pono. I loko o ka ʻoihana hana hale, hoʻohana mau ʻia nā pōhaku kiʻekiʻe alumina refractory i nā mea hana e like me nā kiln rotary sima a me nā kapuahi hoʻoheheʻe aniani. Ma nā kaiapuni me nā wela kiʻekiʻe, kiʻekiʻe ka wikiwiki o ka lele ʻana o ka ea, a me nā mea abrasion, hiki iā lākou ke mālama i ka hana maikaʻi, e kākoʻo ana i ka hana paʻa o ka hana ʻana i nā mea hale. I loko o ka ʻoihana kemika, he mea koʻikoʻi nā alumina refractory kiʻekiʻe i nā umu wela wela a me nā gasifiers. Me ka maikaʻi o ko lākou pale ʻana i ka corrosion kemika, hōʻoia lākou i ka palekana a me ka pono o ke kaʻina hana kemika

Ua lako mākou me nā lako hana kiʻekiʻe a me kahi ʻōnaehana hoʻokele koʻikoʻi. E nānā pono ʻia kēlā me kēia loulou, mai ke kūʻai ʻana i nā mea waiwai a hiki i ka lawe ʻana i ka huahana. Ma ka hoʻokomo ʻana i nā kaʻina hana alakaʻi honua, hōʻoia mākou i ka maikaʻi o nā alumina refractory kiʻekiʻe e hoʻokō i nā kūlana honua. Ma ka manawa like, hāʻawi pū mākou i ke kākoʻo ʻenehana loea a me nā lawelawe ma hope o ke kūʻai aku. E like me nā pono like ʻole o nā mea kūʻai aku, hāʻawi mākou i nā hoʻonā pilikino e hōʻoia i ka hiki ke hana maikaʻi i nā mea hoʻonaninani alumina kiʻekiʻe i nā noi kūpono.​

ʻO ke koho ʻana i kā mākou alumina kiʻekiʻe refractory brick ʻo ia hoʻi ke koho ʻana i ka maikaʻi a me ka hilinaʻi. Inā makemake ʻoe i ke kūʻai nui nui a i ʻole nā ​​mea hoʻonā ʻenehana refractory, hiki iā mākou ke hoʻokō i kāu mau koi. Hoʻokipa maikaʻi mākou i nā mea kūʻai mai ka honua holoʻokoʻa e hoʻokaʻaʻike mai iā mākou a hana pū i ka wā e hiki mai ana no ka ʻoihana wela kiʻekiʻe!​
