Chrome corundum castable is a high-performance amorphous refractory material composed of corundum and chromium.
It has high melting point, high hardness, high stability and excellent slag resistance and wear resistance.
In chrome corundum castable, corundum can provide additional refractory performance and strength, complementing chrome corundum to further improve the overall performance of the castable.
(1) Excellent high temperature resistance
(2) High strength
(3) Good wear resistance
(4) Strong corrosion resistance
(5) Good thermal shock stability
