Chrome corundum brick is a high-performance refractory material produced from fused corundum, chromium oxide, and alumina micropowder, accurately proportioned and processed through high-temperature sintering.
High hardness with excellent wear and erosion resistance.
Good high-temperature strength and structural stability.
Excellent resistance to slag corrosion and penetration.
Minimal permanent linear change at high temperatures.
High density and low porosity, providing a long service life.
Non-ferrous metal smelting: Linings of various high-temperature furnaces.
Other industrial kilns: Equipment operating under severe corrosion and erosion conditions.
