Les mat\u00e9riaux alcalins pour les cimenteries sont principalement compos\u00e9s d'oxydes alcalins (tels que MgO, CaO), qui pr\u00e9sentent une forte r\u00e9sistance \u00e0 l'\u00e9rosion du laitier alcalin et sont souvent utilis\u00e9s dans des environnements d'atmosph\u00e8re oxydante \u00e0 haute temp\u00e9rature.<\/p>\n

Mat\u00e9riaux r\u00e9fractaires en magn\u00e9sium<\/a><\/h3>\n

Caract\u00e9ristiques : Avec l'oxyde de magn\u00e9sium (MgO) comme composant principal, il a une r\u00e9fractarit\u00e9 \u00e9lev\u00e9e (\u22652000\u2103), une forte r\u00e9sistance \u00e0 l'\u00e9rosion du laitier alcalin, mais une faible r\u00e9sistance aux chocs thermiques.
\nApplication : Zone de cuisson et zone de transition des fours rotatifs (r\u00e9sistance aux temp\u00e9ratures \u00e9lev\u00e9es et \u00e0 l'\u00e9rosion des mat\u00e9riaux alcalins).<\/p>\n

Mat\u00e9riaux r\u00e9fractaires au magn\u00e9sium et au chrome<\/a><\/h3>\n

Caract\u00e9ristiques : L'oxyde de magn\u00e9sium et l'oxyde de chrome (Cr\u2082O\u2083) sont compos\u00e9s, combinant une r\u00e9fractarit\u00e9 et une r\u00e9sistance \u00e0 l'\u00e9rosion \u00e9lev\u00e9es, ainsi qu'une r\u00e9sistance \u00e0 haute temp\u00e9rature.
\nApplication : Zone \u00e0 haute temp\u00e9rature du four rotatif (telle que la zone de cuisson), mais son utilisation est progressivement restreinte en raison des probl\u00e8mes de protection de l'environnement (pollution par le chrome hexavalent).<\/p>\n

R\u00e9fractaire \u00e0 base de spinelle de magn\u00e9sium-aluminium<\/a><\/h3>\n

Caract\u00e9ristiques : L'oxyde de magn\u00e9sium et l'oxyde d'aluminium (Al\u2082O\u2083) synth\u00e9tisent le spinelle (MgAl\u2082O\u2084), qui pr\u00e9sente une meilleure r\u00e9sistance aux chocs thermiques que les mat\u00e9riaux en magn\u00e9sium et une bonne r\u00e9sistance \u00e0 la corrosion.
\nApplication : zone de transition du four rotatif, section \u00e0 haute temp\u00e9rature du refroidisseur.<\/p>\n
