Kutentha kogwira ntchito ndikugwiritsa ntchito njerwa zamoto zopepuka zopepuka 2

3. Alumina dzenje mpira njerwa

Zida zake zazikulu ndi mipira yopanda kanthu ya aluminiyamu ndi aluminium oxide ufa, wophatikizidwa ndi zomangira zina. Ndipo amawotchedwa pa kutentha kwakukulu kwa madigiri 1750 Celsius. Ndi ya ultra-high kutentha mphamvu zopulumutsa ndi kutchinjiriza zipangizo.
Ndizokhazikika kwambiri kuti zigwiritsidwe ntchito m'malo osiyanasiyana. Makamaka oyenera ntchito mu kilns kutentha kwambiri pa 1800 ℃. Mipira yopanda kanthu imatha kugwiritsidwa ntchito ngati kutentha kwambiri komanso kopitilira muyesokutentha insulation fillers, opepuka aggregates kwa mkulu-kutentha refractory konkire, mkulu-kutentha castable, etc. Malinga ndi zizindikiro thupi ndi mankhwala, zotayidwa dzenje mpira njerwa chimagwiritsidwa ntchito mu mkulu-kutentha ndi kopitilira muyeso-mkulu kutentha kilns monga gasifiers makampani petrochemical, ng'anjo carbon wakuda makampani anachita, zitsulo zitsulo, makampani kupatsidwa ulemu, ndi zina zotero.
