Abstract

L'invention concerne un garnissage ou un revêtement de four comprenant une composition d'alumine et d'oxyde de chrome. La composition est constituée par 55 à 97 % de grains d'alumine fondue ou tabulaire, 4 à 18 % de fines d'alumine fondue ou tabulaire, 0 à 10 % d'alumine calcinée et 3 à 17 %' d'oxyde chromique de qualité pour matières réfractaires. La matière tassée à sec ou vibrée présente une propriété d'autoliaison au cours du chauffage initial et le garnissage qui en est formé a une durée de vie supérieure.Disclosed is a furnace lining or coating comprising a composition of alumina and chromium oxide. The composition consists of 55 to 97% grains of fused or tabular alumina, 4 to 18% of fines of fused or tabular alumina, 0 to 10% of calcined alumina and 3 to 17% of chromic oxide. quality for refractory materials. The dry-packed or vibrated material exhibits a self-bonding property during the initial heating and the packing formed therefrom has a longer life.
