Chromic corundum brick is main and mineral composition is α - the solid solution of Al2O3-Cr2O3. Less important and mineral composition is a few compound pointed spar (or do not contain compound pointed spar) , the firebrick that oxidation chromic content is 1%~30% . Have brick of corundum of brick of founding chromic corundum and agglomeration chromium two kinds. Usually chromic corundum brick points to brick of agglomeration chromic corundum namely.
Chromic corundum brick also is called brick of chamfer of tapping of tall wear-resisting chromic corundum by people, it is with pure alumina Al2O3 and oxidation chromium Cr2O3 is main raw material. It is with zirconium stone pink add thing, by certain grain compositive pole matchs, make bond with waste liquid of sulphurous acid pulp, below 150Mpa pressure suppress shapes. Sample base substrate is dry below 100 ℃ temperature 4 hours, fall in 1750-1800 ℃ temperature next firing.
Below high temperature, cr2O3 and Al2O3 fashion successive solid solution, the excel of high temperature capability of chromic corundum brick is consequently pure corundum brick. Compare with photograph of pure corundum brick, it has better performance, be like fireproof degree, loading bate is out of shape temperature, fight lose stability of bulk of creep of intensity, high temperature, high temperature and sex of the corrode that fight broken bits. Basically use at steel rolling heating furnace slippery course and tapping platform, chamfer, reach other industry furnace is easy wear away place.
Because the content of Cr2O3, Al2O3 and Fe2O3 is different, and of intensity of compression of density of apparent pore rate, bulk, normal temperature different created price difference. The price of brick of chromic corundum of chamfer of this kind of tapping not only greatly under the tapping chamfer brick that is material to pledge with wear-resisting of tall alloy heat-resisting, and also under brick of corundum of electric frit zirconium, say originally to reducing production to become, it is an advantageous element undoubtedly.
