ʻO nā pōhaku lepo pale alumina kiʻekiʻe (Papa I, II, III)

ʻO ka pōhaku alumina kiʻekiʻe he mea refractory kūʻokoʻa, kahi i kū ai ka corrosion i ka waikawa a me ka alkaline slag, a ua ʻike ʻia e ka ikaika compressive kiʻekiʻe, ke kūpaʻa erosion, ke kūpaʻa komo ikaika, a me ka hoʻomaka ʻana o ka haʻahaʻa haʻahaʻa kiʻekiʻe.

High alumina refractory brick
(Papa I, II, III)

Kiʻekiʻe compressive ikaika, kiʻekiʻe haawe softening mahana, anti peeling

Hana ʻia nā pōhaku kiʻekiʻe alumina refractory i ka alumina bauxite kiʻekiʻe ma ke ʻano he kumu nui ma ka hoʻoikaika ʻana i ka hui kokoke o ka matrix a me nā ʻāpana, hoʻohui i ka mea hoʻopili composite, a me ka sintering i ka wela kiʻekiʻe.Loaʻa iā ia nā hiʻohiʻona o ke kūpaʻa kiʻekiʻe kiʻekiʻe, ka wela hoʻoluʻu haʻahaʻa kiʻekiʻe, anti peeling, a me nā mea ʻē aʻe.

Paʻa leo maikaʻi ma ka wela kiʻekiʻe.Ka ikaika mechanical kiʻekiʻe.Kūleʻa maikaʻi ke komo.ʻOiʻo ka ʻiʻo.Haʻahaʻa porosity.Kūleʻa maikaʻi i ka slag.He haʻahaʻa ka mea hao oxide.

Loaʻa ka nui o nā pōhaku alumina kiʻekiʻe, nā pōhaku lepo, nā pōhaku corundum, nā pōhaku silika carbide a me nā pōhaku lepo.I loko o ka umu ahi, ma muli o nā ʻano hana like ʻole o kēlā me kēia ʻāpana, nui ka piʻi ʻana o ka mahana, a ʻokoʻa hoʻi ka haʻalulu wela i lawe ʻia e kēlā me kēia ʻāpana, no laila ʻokoʻa ka refractory e koi ʻia e kēlā me kēia ʻāpana.
