Ka wehewehe ʻana o ka Corundum Mullite Castable
ʻO ka Corundum mullite refractory castable kahi ʻano mea refractory ikaika kiʻekiʻe i kūʻai ʻia ma RS Company, hiki ke hoʻohana ʻia i loko o ka umu sima. Hiki i nā Corundum mullite castables ke hana i nā waiwai kiʻekiʻe e like me ka ikaika kuʻi kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe, ke kū'ē ʻana i ka haʻalulu wela, ke kū'ē ʻana i ka ʻaʻahu a me ka pale ʻana i ka erosion kemika i loko o ka paila kikowaena mana nui a me nā lako hana wela kiʻekiʻe ʻē aʻe. hiki ke hoʻohana ʻia ka refractory corundum mullite castable i loko o ka umu kila, ka umu sima, ka umu aniani, ka umu hana hao, ka umu tunnel seramika a pēlā aku.
Nā Waiwai o ka Corundum Mullite Castable
- Ikaika kiʻekiʻe,
- Ke kūpaʻa ikaika o ka ʻaʻahu,
- Kū'ē maika'i i ka erosion,
- Paʻa haʻalulu wela maikaʻi loa,
- Ke kūpaʻa wela kiʻekiʻe.
Ke Kaʻina Hana Hana o Corundum Mullite Castable
ʻO nā mea maka nui o ka corundum mullite castable he aggregate alumini oxide māmā, ka ore mullite kūlohelohe maʻemaʻe kiʻekiʻe, a me ka sima calcium aluminate ma ke ʻano he mea hoʻopaʻa. Hana ʻia ka corundum mullite refractory castable ma o ka puhi ʻana i ka mahana kiʻekiʻe e ka umu ʻoihana holomua. Hoʻonui mua ka ikaika flexural corundum mullite a me ka ikaika compressive a laila emi iho me ka hoʻonui ʻana o ka mahana lapaʻau wela. A i ka wā e 5% ai ka nui o ka mana micro alumina, hiki i ka ikaika flexural i luna.
ʻO ka haku mele ʻana o ka Corundum Mullite Castable
ʻOi aku ka nui o ka Al2O3 ma mua o 90%, a ua hui pū ʻia ka corundum mullite insulation me ka corundum ma ke ʻano he kristal nui me nā mea hoʻolaha kūpono, nā coagulants, nā olonā kila kila, i hui pū ʻia e like me ke ʻano paʻa. He nui nā ʻano o ka refractory corundum mullite castable, e like me ka ikaika wela kiʻekiʻe, ke kū'ē i ke komo ʻana a me ka anti-scour, ka hoʻokele wela kiʻekiʻe, ke kū'ē i ka haʻalulu wela, ke kū'ē i ka corrosion, ka sila maikaʻi a me ka condensation mua.

Ka hoʻohana ʻana o ka Corundum Mullite Castable
ʻO ka Corundum mullite refractory castable he mau hiʻohiʻona o ka hoʻonui like ʻana, ke kūpaʻa haʻalulu wela maikaʻi loa, ke kūpaʻa o ka nui o ka mahana kiʻekiʻe, ka ikaika wela kiʻekiʻe, ke kūpaʻa kiʻekiʻe ma lalo o ke kaumaha, ka nui o ka kolo wela kiʻekiʻe, ka ikaika kuʻi kiʻekiʻe, ka nui o ka loli linear dimensional, ka paʻakikī kiʻekiʻe, ke kūpaʻa maikaʻi i ka corrosion kemika, ka spalling a me ke kūpaʻa ʻaʻahu. Ma muli o ia mau ʻano, a me ka corundum mullite insulation castable he paʻa i ka hoʻohana ʻana a ua hoʻohana nui ʻia i nā umu ʻoihana like ʻole, ka umu wela kiʻekiʻe a me nā ʻāpana koʻikoʻi ʻē aʻe o ka mahana kiʻekiʻe, e like me:
- Ka paila, ka umu pahū, ka umu pahū wela, ka umu hoʻomehana,
- ʻUmu ahi tunnel seramika, ʻumu sima, mea puhi lanahu,
- Puka umu, wehe ʻana i ka meaʻai, nā umu kila, nā umu hana hao,
- Keʻena kuni, ʻōheu i hoʻohuli ʻia,
- Ka paila kikowaena mana nui, ka umu aniani.
