ʻO nā pahu sima haʻahaʻa kekahi ʻano o ka refractory castable me kahi mahana lawelawe kiʻekiʻe ma luna o 1550 ℃, e hoʻohana ana i ka sima aluminate e like me kāna mea hoʻopaʻa, kahi i emi iho ai ka nui o CaO ma mua o 2.5%. ʻO ka hui ʻana o ka refractory haʻahaʻa sima castable ka nui o ka refractory aggregate, refractory pauda a me ka wai. Hoʻohālikelike me ka kuʻuna refractory castable, haʻahaʻa sima refractory castable i ka moʻo o ka maikai hana e like me ka haʻahaʻa sima, haʻahaʻa porosity, maikai leo paʻa a kiʻekiʻe anu curing-ikaika. A ʻoi aku ka kiʻekiʻe o ke kiʻekiʻe sima haʻahaʻa ma mua o nā castable refractory ʻē aʻe.
ʻO ke kima haʻahaʻa haʻahaʻa he refractory castable i hana ʻia me ka pauka ultrafine, aluminate sima a me kekahi mau mea hoʻohui. Eia kekahi, hiki i ka nui o kēia mau composite ke hoʻololi i kāna hana. ʻO ka nui o ka wai, hāʻawi ʻia i ka maʻalahi o ka hui ʻana i nā mea, hiki i ka hoʻohui ʻana i ka wai liʻiliʻi ke hoʻohaʻahaʻa i ka porosity a hoʻomaikaʻi i ka ikaika. Loaʻa ka maikaʻi o ka liʻiliʻi o ka wai, kiʻekiʻe kiʻekiʻe a me ka ikaika kiʻekiʻe, ʻo ia ke kumu i hoʻohana nui ʻia ai kēia mea refractory i nā kīhāpai a me nā kapuahi like ʻole a me nā kiln.
Kiʻekiʻe Refractory Mahana a me ka ikaika a me High Anti - Slag Corrosion Kū'ē.
Haʻahaʻa Porosity a High Bulk Density. I loko o ke kaʻina hana, ʻo 1/3 ~ 1/2 wale nō ka nui o ka wai no ka castable kuʻuna e hoʻohui ʻia i loko.
Hoʻonui i ka ikaika me ka hoʻomaikaʻi ʻana i ka wela o ka mālama ʻana i ka wela ma hope o ka hoʻolei ʻana i loko o ke ʻano: Me ka hoʻoponopono kūpono o ka nui castable, hiki ke hoʻohui ʻia i loko o ka hoʻoheheʻe ponoʻī a me nā mea ninini wai.
