ʻO ka pōhaku kalapona Magnesite alumina kahi ʻano pōhaku refractory i hana ʻia me ka alumina bauxite kiʻekiʻe a i ʻole emery, magnesia a me ka graphite flaky ma ke ʻano he mea nui. Loaʻa i ka pōhaku kalapona magnesia alumina nā ʻano o ke kūpaʻa kiʻekiʻe i ka palaho, ke kūpaʻa kiʻekiʻe a me ke ʻano mechanical maikaʻi ma lalo o ke kiʻekiʻe o ka mahana, a pēlā aku. Hoʻohana nui ʻia ka pōhaku kalapona Magnesia alumina i loko o ka liner ladle kila hoʻoheheʻe koʻikoʻi. A hoʻohana ʻia hoʻi ka pōhaku kalapona magnesia alumina i loko o ka ʻauʻau hoʻoheheʻe a me ka lalo ladle o ka hoʻolei mau ʻana i ka tundish nui a me ka pūʻolo hoʻomaʻemaʻe umu waho e hoʻonui ʻia ana.
Nā Waiwai o nā Piliki Kalapona Magnesia Alumina
- ʻO ka porosity haʻahaʻa a me ka conductivity wela haʻahaʻa,
- Kū'ē maika'i i ka ha'alulu wela,
- Ka ikaika kiʻekiʻe, ka pale ʻana i ka pala,
- Kū'ē maika'i i ka ʻino, kū'ē ki'eki'e i ka slag,
- Maikaʻi loa ka anti-oxidation a me ka anti-stripping hiki.
Nā Pōmaikaʻi o nā Piliki Kalapona Magnesia Alumina
Loaʻa i nā piliki kalapona Magnesia alumina ka anti-erosion, anti-stripping, antioxidant a me nā koena ʻaʻole sticky etc.. Ua hoʻohana nui ʻia ka piliki kalapona magnesium alumina i loko o ka ladle i ka hoʻolei mau ʻana a ma kekahi ʻano ua hoʻomaha i ke kūʻē ʻana i ke ola ladle hoʻolei mau haʻahaʻa.
Ke Kaʻina Hana Hana ʻana o nā Piliki Kalapona Magnesia Alumina
ʻO ka poloka kalapona Magnesia alumina ka mea maka refractory me ka bauxite papa kūikawā
ʻO ka magnesite a i ʻole corundum a me ka flake graphite, ka mea i hōʻike ʻia i ke kiʻekiʻe o ka mahana me ke kalapona kiʻekiʻe me ke kūpaʻa kiʻekiʻe o ka corrosion a me nā pono anti stripping, loaʻa pū kekahi
ka wela i hana ʻia e ka hoʻohana ʻana i ka spinel a hōʻike i ke koena laina o ka lakio hoʻonui kiʻekiʻe
nā pono, ua lilo i mea hoʻomohala hou o nā piliki lining kiʻekiʻe.

Ka hoʻohana ʻana o nā pōhaku kalapona Magnesia Alumina
Hoʻohana nui ʻia nā pōhaku ahi kalapona magnesium alumina i loko o ka ladle i ka hoʻolei mau ʻana a ma kekahi ʻano ua hōʻoluʻolu i ke kūʻē ʻana o ke ola ladle hoʻolei mau haʻahaʻa. Hiki ke hoʻohana ʻia nā pōhaku ahi kalapona magnesium alumina ma kēia wahi:
- 1.Nā mea hoʻololi, EAF, nā umu hoʻomaʻemaʻe,
- 2. Laina slag a me ka laina metala no ka ladle,
- 3. Papa hana umu ʻāʻī uila,
- 4. Papa hana umu hoʻololi,
- 5.Umu uila nui, uhi ladle a me ka hoʻomaʻemaʻe ʻana ma waho o ka umu.
