ʻO nā pōhaku lepo hoʻokaʻawale māmā Mullite
Hōʻike huahana
ʻO nā pōhaku lepo mullite māmā he porosity kiʻekiʻe, hiki ke mālama i ka wela a no laila e hoʻemi i ke kumukūʻai o ka wahie.I kēia manawa, ʻoi aku ka liʻiliʻi o ke kaumaha māmā, no laila ʻoi aku ka liʻiliʻi o ka manawa i ka wā e wela ai a maʻalili paha ka kiln.ʻOi aku ka wikiwiki o ka hana maʻamau.
Hiki ke hoʻohana ʻia ma ka pae wela mai 900 a 1600 ℃.
Hoʻohana nui ʻia e like me ke kiln lining i ke kiʻekiʻe kiʻekiʻe (ma lalo o 1700 ℃) kiln o nā seramika, petrochemical, metallurgy a me nā mīkini.
Nā hiʻohiʻona maʻamau
Haʻahaʻa thermal conductivity, haʻahaʻa wela wela, haʻahaʻa haumia maʻiʻo
ʻO ka ikaika kiʻekiʻe, ke kūpaʻa haʻalulu wela maikaʻi loa, ke kūpaʻa erosion
Anana pololei
Hoʻohana maʻamau
ʻO ka ipu kīwila kīwila a me ka umu kaʻa kaʻa: pōhaku maʻamau, pōhaku lepo lua, pōhaku hanger,
ʻOihana Metallurgy: umu wela wela;ka uhi o loko o nā kiln hana
ʻOihana mana: hana mana a me nā lako moe wai
ʻOihana Aluminum Electrolytic: kiln i loko
Nā waiwai huahana maʻamau
