ʻO ka piliki corundum Chrome e pili ana i kahi huahana corundum refractory i loaʻa iā Cr2O3. I ke ana wela kiʻekiʻe, hana ʻo Cr2O3 a me Al2O3 i kahi hopena paʻa mau, no laila ʻoi aku ka maikaʻi o ka hana wela kiʻekiʻe o nā huahana chrome corundum ma mua o nā huahana corundum maʻemaʻe. ʻO ka piliki ahi corundum Chrome i hoʻohana ʻia i ka gasifier petrochemical e pono ke silicon haʻahaʻa, hao haʻahaʻa, alkali haʻahaʻa a me ka maʻemaʻe kiʻekiʻe, a pono e loaʻa ke kiʻekiʻe o ka density a me ka ikaika. Aia ka ʻike o Cr2O3 ma ka pae o 9% ~ 15%.
Nā hiʻohiʻona o nā pōhaku lepo Chrome Corundum
- Ke kūpaʻa ahi kiʻekiʻe,
- Ka ikaika nui,
- Ke kūpaʻa maikaʻi o ka ʻaʻahu,
- Kū'ē maika'i i ka ha'alulu wela,
- ʻO ke kūpaʻa maikaʻi o ka waikawa a me ka alkali,
- Paʻa kemika maikaʻi.
Kaʻina Hana Hana Piliki Chrome Corundum
Hoʻopili ʻia ka piliki corundum Chrome me ka post-al2o3, e hoʻohui ana i kahi nui o ka pauka chromium oxide a me ka pauka maikaʻi o ka clinker chrome corundum, i hana ʻia a puhi ʻia i ke ana wela. ʻOi aku ka haʻahaʻa o ka nui o ka chromic oxide i loko o ka piliki chrome sintered ma mua o ka piliki chrome corundum i hoʻoheheʻe ʻia. Hoʻohana pū ka poloka corundum Chrome i ke ʻano hoʻomākaukau no ka hoʻolei ʻana i ka lepo, ka pauka alpha Al2O3 a me ka pauka chrome oxide e hui pū ana, e hoʻohui i ka glue a me nā mea hoʻopili organik i hana ʻia mai ka lepo mānoanoa, i ka manawa like he ʻāpana o ka clinker chromium corundum, ma ka grout ʻana i loko o ka adobe, e puhi hou ana.

Ka hoʻohana ʻana i ka pōhaku Chrome Corundum no ka umu ahi
Hoʻohana nui ʻia ka piliki corundum Chrome ma nā wahi e pono ai ke kūpaʻa kiʻekiʻe a me ke kūpaʻa wela, e like me nā piliki kaʻaahi gliding i loko o nā umu metallurgical pusher kila, nā umu hele wāwae ʻano tapping platform, a me ke ʻano o loko no nā mea luku, I loko o nā uhi o ka umu soot kalapona a me ke kahua tapping umu ʻala keleawe o ka umu wili wili, hoʻomehana hou i ka ʻaoʻao skid umu.
