Pili ʻo Chrome corundum brick i kahi huahana refractory corundum i loaʻa iā Cr2O3. Ma ka wela kiʻekiʻe, Cr2O3 a me Al2O3 e hana i ka 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. Hoʻohana ʻia ʻo Chrome corundum ahi pōhaku i loko o ka petrochemical gasifier he haʻahaʻa silika, haʻahaʻa hao, haʻahaʻa alkali a me ka maʻemaʻe kiʻekiʻe, a pono ke kiʻekiʻe kiʻekiʻe a me ka strength.The maʻiʻo o Cr2O3 i loko o ka laulā o 9% ~ 15%
ʻO Chrome Corundum Brick hiʻohiʻona
- Kūleʻa ahi kiʻekiʻe,
- Ka ikaika nui,
- Kūleʻa maikaʻi i ka ʻaʻahu,
- Kūleʻa haʻalulu maikaʻi,
- ʻO ke kūpaʻa maikaʻi o ka waikawa a me ka alkali,
- Paʻa kemika maikaʻi.
Ke Kaʻina Hana Hana Brick Corundum Chrome
Hoʻohana ʻia nā pōhaku lepo Chrome corundum me ka post-al2o3, me ka hoʻohui ʻana i kahi nui o ka pauka chromium oxide a me ka pauka maikaʻi o ka chrome corundum clinker, i hana ʻia a puhi ʻia i ka wela kiʻekiʻe. ʻOi aku ka haʻahaʻa o ka maʻiʻo o ka chromic oxide i loko o nā brick chrome sintered ma mua o ko ka fused cast chrome corundum brick. Hoʻohana pū ʻia ʻo Chrome corundum block i ke ʻano o ka hoʻomākaukau ʻana i ka lepo, ka pauka alpha Al2O3 a me ka hui ʻana o ka pauka chrome oxide, hoʻohui i ke kāpili a me nā mea hoʻopili kūlohelohe i hana ʻia mai ka lepo mānoanoa, i ka manawa like me kahi ʻāpana o ka chromium corundum clinker, ma ka grouting i loko o ka adobe, e puhi hou ana.

Hoʻohana ʻia ʻo Chrome Corundum Brick no ka umu ahi
Hoʻohana nui ʻia ʻo Chrome corundum brick i nā wahi e koi ai i ka abrasion kiʻekiʻe a me ke kūpaʻa wela, e like me ka gliding rail bricks i ke kila pusher metallurgical furnaces, ke kāʻei ʻana i ke anuu e hele ana i nā kapuahi kapuahi, a e like me ka loko no nā mea luku, I nā linings o ka umu kalapona soot. a me ke kapuahi honi keleawe o ka umu ahi wiliwili, e ho'owela hou ana i ke kapuahi skid.
