Chrome-corundum Castable

Chrome-corundum Castable is mainly made of corundum and chromic oxide micro powders. Featured by high thermal strength, good abrasion resistance and thermal shock resistance, the product is mainly used in the antiscouring and wearable parts of the high-temperature kiln. It can be produced into precast bricks by undergoing medium-low temperature baking or high- temperature sintering.
