Description
Corundum Silicon Carbide Carbon ultra-low cement castable is a kind of refractory material composed of sintered or fused corundum and silicon carbide as aggregates, sintered/fused corundum powder, silicon carbide powder, and graphite as the substrate, and ultra-low cement as the binder. This castable exhibits excellent high-temperature performance, especially the resistance to molten iron and slag penetration and corrosion.
