High aluminum castable refers to a refractory castable with Al2O3 content greater than 48%, which is a refractory material composed of high bauxite, corundum and other aggregates, powders, and adjuvants such as binders and admixtures.
It has the advantages of high temperature strength, good wear resistance and strong erosion resistance, and is widely used in high temperature industrial fields such as steel, non-ferrous metals, electric power and petrochemical.
(1) Good high temperature strength
(2) Good thermal shock resistance
(3) Wear resistance and erosion resistance
(4) Strong chemical stability
(5) Good volume stability
(6) Good corrosion resistance
(7) Low high temperature creep rate
