ʻO nā Bricks Refractory Alumina i ka ʻoihana kila

ʻO nā pōhakuʻeleʻele alumina heʻano ia o nā mea pale i hoʻohanaʻia i kaʻoihana kila. Hoʻokumu ʻia nā pōhaku lepo me ka alumina, kahi mea i kūpaʻa loa i ka wela, ka ʻino, a me ka lole. Hoʻohana ʻia nā pōhaku lepo pale alumina i ka ʻoihana kila e kūkulu i ka lining a me ka insulation no nā kapuahi, kiln, a me nā mea hana wela kiʻekiʻe. ʻO nā pōhaku lepo pale alumina ka lōʻihi loa a hāʻawi i ka insulation thermal kiʻekiʻe a me ke kūpaʻa corrosion. Hiki i nā pōhaku lepo ke kū i nā mahana a hiki i 2000°C (3632°F). Hiki ke hoʻemi ʻia ka hoʻohana ʻana i ka ikehu a hoʻonui i ka pono. ʻO ka alumina refractory bricks he kiʻekiʻe kiʻekiʻe o ke kūpaʻa kemika, a hiki iā ia ke kū i ke kaiapuni corrosive o ka hana kila. Paʻa loa ka mea i ka abrasion a me ka ʻaʻahu, e kūpono ana ia no ka hoʻohana ʻana i nā noi wela kiʻekiʻe. Loaʻa nā ʻāpana alumina refractory i nā ʻano like ʻole a me nā nui, me nā poloka, cubes, a me nā papa. Hiki ke ʻoki a hana ʻia nā pōhaku lepo e kūpono i nā ana kūpono o ka umu ahi a i ʻole kiln. Hoʻohana mau ʻia nā pōhaku lepo e laina i nā paia, ke kaupaku, a me ka papahele o ka hale. Hoʻohana mau ʻia nā pōhaku lepo pale alumina i nā mea hana kila a me nā mea hoʻokumu. Hoʻohana ʻia lākou e laina i nā paia, ka papahele, a me ke kaupaku o ka umu, kiln, a me nā mea hana ʻē aʻe. Hoʻohana ʻia nā pōhaku lepo i nā noi ʻē aʻe e like me ka hoʻopaʻa ʻana i nā paia o nā umu ahi, nā ladles, a me nā mea hoʻololi. Hana ʻia nā pōhaku lepo pale alumina mai kahi hui ʻana o ka alumina, silica, a me ka magnesia. Hoʻopau ʻia nā pōhaku lepo i nā mahana kiʻekiʻe e hana i kahi mea paʻa a paʻa. Hiki ke hui pū ʻia nā pōhaku lepo me nā mea ʻē aʻe, e like me ka silicon carbide, e hoʻonui ai i ke kūʻē ʻana o ka mea i ka corrosion a me ka lole. ʻO nā pōhaku lepo pale alumina he mea nui o ka ʻoihana kila. Ke hoʻomau nei ka ulu ʻana o ka ʻoihana kila a me nā mea hou, e lilo ka hoʻohana ʻana i kēia mau pōhaku i mea maʻamau. Hāʻawi nā pōhaku lepo i ka insulation thermal kiʻekiʻe a me ka pale ʻana i ka corrosion, e hoʻolilo iā lākou i koho kūpono no ke kaiapuni koi o ka hana kila.
