ʻO Corundum a me Corundum-mullite Bricks Series
wehewehe
ʻO nā pōhaku lepo ʻo Corundum kahi ʻano o ka huahana refractory aluminika-silikona me ka corundum ma ke ʻano he aniani nui.Ma ka hoʻohui ʻana i kekahi mau ʻāpana mineral kemika, hiki iā ia ke hana i nā huahana composite, e like me ka zirconium corundum bricks, chrome corundum bricks, titanium corundum bricks, etc.
Nā hiʻohiʻona
Loaʻa i nā pōhaku lepo Corundum nā hiʻohiʻona o ka helu hoʻoheheʻe kiʻekiʻe, ka pale ʻana i ka slag maikaʻi, ka ikaika kiʻekiʻe a me ka paʻakikī, a me ke kūpaʻa abrasion.
ʻO nā pōhaku lepo Corundum mullite maikaʻi ka ikaika wela kiʻekiʻe, ke kūpaʻa kiʻekiʻe kiʻekiʻe o ke kolo, ke kūpaʻa haʻalulu wela a me ke kūpaʻa erosion.
Palapala noi
Hoʻohana pinepine ʻia nā pōhaku Corundum i ka metallurgy, ka ʻoihana kemika, ke aniani, ka seramika a me nā ʻāpana kiln ʻoihana ʻē aʻe.
Corundum mullite bricksHoʻohana nui ʻia i loko o ka umu ahi aniani superstructure, hānai kahawai brick, uhi pā, ʻāpana ʻāpana, waena wela kalapona ʻeleʻele reactor lining a me nā mea wela ʻē aʻe.
