Hoʻolālā Hoʻolaha Uila Kūlana kiʻekiʻe

ʻO ka hoʻolālā a me ka hoʻololi ʻana i ka fiber insulation o nā umu hao ʻo Ironmaking Blast a me nā kapuahi wela

Hoʻolauna i ka hoʻolālā hoʻoweliweli kumu o nā kapuahi pahū a me nā kapuahi wela-wela:

ʻO ka umu ahi kahi ʻano pono hana mehana me kahi hanana paʻakikī. ʻO ia nā pono hana nui no ka hana hao ʻana a loaʻa nā maikaʻi o ka hoʻopuka nui, hana kiʻekiʻe, a me nā kumukūʻai haʻahaʻa.
No ka mea he kiʻekiʻe loa ka mahana hana o kēlā me kēia ʻāpana o ka umu ahi, a hoʻokau ʻia kēlā me kēia ʻāpana i nā hopena mechanical, e like me ka hakakā a me ka hopena o ka hāʻule ʻana, ʻo ka hapa nui o nā mea wela wela e hoʻohana i nā pōhaku uila wela wela CCEFIRE e hiki mai ana. me nā mahana hoʻonāwaliwali kiʻekiʻe ma lalo o ka ukana a me nā ikaika mechanical temp-kiʻekiʻe maikaʻi.
Ma ke ʻano he lako pono kōkua nui o ka lua ahi, ka umu ahi wela e hāʻawi i ka wela wela kiʻekiʻe i ka umu ahi ma o ka hoʻohana ʻana i ka wela mai ka puhi ahi hoʻā ahi a me nā hopena hoʻololi wela o ka lattice brick. Ma muli o ka lawe ʻana o kēlā me kēia ʻāpana i nā hopena kiʻekiʻe o ke kuni ʻia ʻana o ke kinoea, ka lū ʻia ʻana o ka lepo i lawe ʻia mai e ke kinoea, a me ke kuʻi ʻia ʻana o ke kinoea kuni, koho pinepine ʻia nā mea wela wela o CCEFIRE i nā pōhaku hoʻohiehie mālamalama, nā pōhaku lepo kūpale, nā pōhaku lepo, a me nā mea ʻē aʻe. nā mea me nā ikaika mīkini maikaʻi.
I mea e hōʻoia pono ai i nā hopena hoʻowahāwahā o ke aniani o ka umu ahi, e pili ana i nā kumumanaʻo o ke koho loea loea, waiwai a me nā kumu kūpono, ke uhi ʻana o ka papa hana wela o ka umu ahi a me kāna umu wela wela e koho maʻamau i nā mea hoʻohuihui i loaʻa haʻahaʻa conductivity a me nā hana hoʻohuihui maikaʻi.
ʻO ke ʻano kuʻuna maʻamau ke koho ʻana i nā huahana papa silicate calcium, nona kēia ʻano pilikino hoʻohuihui kikoʻī: nā pōhaku uila aluminika kiʻekiʻe + hale papa silica-calcium me kahi mānoanoa hoʻopulapula e pili ana i 1000mm.

ʻO kēia nā ʻāpana hoʻokaʻawale pumehana i nā hemahema i lalo i ka noi:

H. He nui nā mea hoʻoweliweli mehana a me nā hopena pilikino maikaʻi ʻole.
B. ʻO nā papa silikona-calcium i hoʻohana ʻia i ka pale lining hope e hiki ke haki maʻalahi, hana i nā puka ma hope o ka haki ʻana, a lilo i ka wela.
C. Lilo nui ka mālama ʻana i ka wela, i ka hopena i ka neoneo o ka ikehu.
D. He ikaika ka lawe ʻana o ka wai i nā papa silikika, maʻalahi e haki, a hana maikaʻi ʻole i ke kūkulu ʻana.
E. Hoʻohaʻahaʻa ka mahana o ka noi o nā silicate calcium i 600 ℃
Hoʻohana nā mea hoʻomehana wela i hoʻohana ʻia i ka umu ahi a me kāna umu ahi wela pono e hana maikaʻi i ka hoʻohuihui ʻana. ʻOiai ʻoi aku ka haʻahaʻa o ka conductivity mehana o nā papa silicate kalipika ma mua o nā pōhaku paʻa paʻa a hoʻomaikaʻi ʻia ka hana hoʻomeamea wela, ma muli o ke kiʻekiʻe o ka umu ahi a me nā anawaena umu nui, wāwahi maʻalahi nā papa silicate calcium i ka wā o ke kūkulu ʻana ma muli o kā lākou brittleness, e hopena ana i ka piha ʻole o ka uhi aniani a me nā hopena hoʻohuihui maikaʻi ʻole. No laila, i mea e hoʻomaikaʻi hou ai i nā hopena hoʻowahāwahā o nā kapuahi hao metallurgical a me nā kapuahi wela wela, ua lilo nā huahana pulupulu CCEWOOL (nā pōhaku lepo / papa) i mea kūpono no ka hoʻīpī ma luna o lākou.

Nānā i nā hana ʻenehana nā ceramic ceramic:

Hāʻawi nā paepae ceramic CCEWOOL i nā fibers AL2O3 + SiO2 = 97-99% kiʻekiʻe e like me nā mea maka, i hui pū ʻia me nā mea hoʻopaʻa mea ʻole e like me ke kino nui a me nā mea hoʻopihapiha kiʻekiʻe-temp a me nā mea hoʻohui. Hoʻokumu ʻia lākou e ka hoʻoulu ʻana a me ka pulping ʻana a me ka kānana hoʻoliʻu hakahaka. Ma hope o ka hoʻomaloʻo ʻana o nā huahana, hana ʻia lākou ma o ka moʻo o nā pono hana e hoʻopiha ai i nā kaʻina hana, e like me ke ʻoki ʻana, ka wili ʻana, a me ke ʻeli ʻana e hōʻoia i ka hana o ka huahana a me ka pololei dimensional ma ka pae alakaʻi honua. ʻO kā lākou hiʻohiʻona ʻenehana nui:
a. ʻO ka maʻemaʻe kemika kiʻekiʻe: i loko o 97-99% mau oxide wela kiʻekiʻe e like me Al2O3 a me SiO2, kahi e hōʻoia ai i ke kūpaʻa wela o nā huahana. ʻAʻole hiki i nā panalehana ceramic CCEWOOL ke pani wale i nā papa kalipika kalipona e like me ka uhi ʻana o ka paia o ka umu, akā e hoʻohana pono ʻia hoʻi ma ka ʻili wela o nā paia umu e hoʻowaiwai iā lākou me ke kūpaʻa o ka ʻaʻai ʻana o ka makani.
b. ʻO ka conductivity thermal haʻahaʻa a me nā hopena hoʻowalewale maikaʻi: Ma muli o kēia huahana he huahana CCEWOOL ceramic fiber i hana ʻia e kahi hana hana hoʻomau kūikawā kūikawā, ʻoi aku ka maikaʻi o kāna hana ma mua o nā pōhaku lepo diatomaceous honua, nā papa silicate calcium a me nā mea hana silica i hoʻohui ʻia i loko o kāna haʻahaʻa haʻahaʻa. conductivity, ʻoi aku ka maikaʻi o ka mālama ʻana i nā wela, a me nā hopena mālama mālama ikehu.
c. Ka ikaika kiʻekiʻe a maʻalahi hoʻi e hoʻohana: Loaʻa i nā huahana nā ikaika compressive a me nā flexural kiʻekiʻe a me nā mea non-brittle, no laila hoʻokō pono lākou i nā koina o nā mea ʻili paʻa. Hiki iā lākou ke hoʻohana ʻia i nā papahana hoʻokiwikā me nā koina o ka ikaika nui, i mea e pani ai i nā mea uhi o ka pale a me nā felts. I kēia manawa, loaʻa nā anawaena geometric pololei i ka CCEWOOL i hana ʻia a hiki keʻoki a hana ʻia i ka makemake. ʻOi aku ka maʻalahi o ke kūkulu ʻana, kahi e hoʻonā ai i nā pilikia o ka brittleness, fragility a me ka nui o ka hōʻino o ke kūkulu ʻana i nā papa calcium. Hoʻopōkole loa lākou i ka wā kūkulu a hoʻemi i nā kumukūʻai kūkulu.
I ka hōʻuluʻulu manaʻo, hana ʻia ka fiberboard ceramic CCEWOOL e ka hakahaka me ka ʻole o nā pono mechanical maikaʻi a me nā ana kikoʻī kikoʻī, akā mālama pū kekahi i nā hiʻohiʻona maikaʻi o nā mea hoʻoulu wela fibrous. Hiki iā lākou ke pani i nā papa silikika kalipili a hoʻopili ʻia i nā māla hoʻīpī e koi ai i ka paʻakikī a me ka kākoʻo ponoʻī ʻana a me ke kūpaʻa ahi.

ʻO ke ʻano o ka noi o nā fiberamic ceramic i nā umu hao hao a me nā kapuahi wela

Hoʻohana nui ʻia ke ʻano noi o CCEWOOL ceramic fiberboards i ka hana ʻana i nā umu hao e like me ke kākoʻo ʻana o nā silikone carbide refactory pōhaku lepo, nā pōhaku lepo kiʻekiʻe a i ʻole nā ​​pōhaku uila kiʻekiʻe-alumina, e pani ana no nā papa silicate calcium (a i ʻole brick diatomaceous honua).

Ke noi ma nā umu hao hao a me nā kapuahi wela

Hiki i nā panalehana ceramic CCEWOOL ke pani i ke kinona o nā papa silikika calcium (a i ʻole ka brick honua diatomaceous), a no ka maikaʻi o lākou, e like me ka conductivity thermal haʻahaʻa, ke kiʻekiʻe o ka mahana i ka hoʻohana ʻana, ka hana ʻana i ka mīkini maikaʻi maikaʻi loa, a ʻaʻohe lawe wai, hoʻoponopono maikaʻi lākou i nā pilikia e ke kumu kumu, no ka laʻana, maikaʻi ʻole nā ​​hopena hoʻoweliweli mehana, pohō nui o ka wela, ka nui o ka hōʻino ʻia o nā papa calcium, hana maikaʻi ʻole ke kūkulu ʻana, a me nā ola pōkole o ka uhi hoʻīpī. Ua loaʻa iā lākou nā hopena noi maikaʻi loa.
