Chrome corundum brick is a high-grade refractory material, which is mainly mixed with corundum (α-Al2O3) and an appropriate amount of Cr2O3. It is formed and sintered using good binders and fillers. It has excellent chemical stability, thermal stability, thermal shock stability and high temperature strength. It is mainly used in refractory structural parts in industrial high-temperature furnaces, steel, aluminum, chemical and other industries.

Chrome corundum bricks have the following characteristics:
1. Good high temperature stability, high temperature resistance, can be used in high temperature environments of 1000℃-1700℃.
2. It has good corrosion resistance and good stability against corrosive media such as strong acid, alkali and salt.
3. It has good thermal shock stability, can withstand rapid changes in cooling and heating processes at high temperatures, and is not prone to cracking.
4. It has the advantages of high strength and high hardness, and can be used for structural parts that withstand complex environments such as high temperature and high pressure.
Chrome corundum bricks are widely used in high-temperature furnaces, furnace linings, baking plates, insulation layers and other refractory structural components in metallurgy, chemical industry, electric power, building materials, light industry, glass and other industries, and have important application value.
