Where Are Chrome Corundum Bricks Mainly Used?

As a high-performance refractory material, chrome corundum bricks are mainly used in industrial fields that need to withstand high temperatures, high pressures, and corrosive environments. Their excellent fire resistance, flexural strength, high-temperature creep, high-temperature volume stability, and corrosion resistance make them a key component in many industrial furnaces.

The following are the main areas of application of chrome corundum bricks:

1. Metallurgical industry

Steel smelting: Chromium corundum bricks are widely used in rolling heating furnaces in the steel industry, especially in parts prone to wear such as slide rails, tapping channels, and grooves. Its high wear resistance and long life (up to 10 to 18 months) significantly reduce refractory materials’ consumption and maintenance costs and increase the furnace’s overall life and output value.

Non-ferrous metal smelting: In the process of non-ferrous metal smelting, chrome corundum bricks are used as linings for copper smelting furnaces, zinc smelting electric furnaces, and other equipment due to their superior wear resistance and corrosion resistance, effectively resisting high-temperature melts and corrosion—the erosion of sexual atmosphere.

2. Petrochemical industry Chrome corundum bricks also have important applications in gasifi ers in the petrochemical industry. These gasification furnaces have been exposed to high temperatures (1350~1450℃), high pressures (3.1~8.53MPa), and strong corrosive atmospheres (CO+H₂+CH₄) for a long time, which places extremely high-performance requirements on the lining refractory materials. Chrome corundum bricks can meet these stringent conditions and extend the service life of gasifiers due to their low silicon, low iron, low alkali, high purity, and high density characteristics.

3. Glass Industry In the glass industry, chrome corundum bricks are used as materials for key parts such as glass kiln linings and brushed glass flow hole cover bricks. Its high-temperature stability and erosion resistance ensure the long-term stable operation of the glass kiln while reducing production interruptions due to refractory damage.

4. Environmental protection and hazardous waste disposal industry With the increasing awareness of environmental protection, the application of chromium corundum bricks in the environmental protection and hazardous waste disposal industry is also increasing. For example, in coal-water slurry pressurized gasifier backings, waste incinerators, and other equipment, chromium corundum bricks can resist the erosion of high temperatures and corrosive atmospheres, ensuring the normal operation of the equipment and the environmental protection treatment effect.

To sum up, chrome corundum bricks have been widely used in many fields such as metallurgy, petrochemicals, glass, and environmental protection due to their excellent properties. With the continuous advancement of industrial technology and increasingly stringent environmental protection requirements, the market demand for chrome corundum bricks will continue to grow.
