Performance comparison of Al2O3-C refractory ramming mass with other materials

In the field of refractory materials, Al2O3-C refractory ramming material has gradually become one of the preferred materials for high-temperature industrial applications due to its excellent high-temperature performance and corrosion resistance. This article will discuss in detail its performance comparison with other refractory materials, such as high-alumina bricks, magnesia carbon bricks, etc., and analyze key indicators such as heat resistance, corrosion resistance and service life to help companies make wise decisions in the material selection process.

Heat resistance comparison

Al2O3-C refractory ramming mass has extremely high heat resistance and can work stably for a long time in an environment with a temperature range of 1500°C to 1800°C. In contrast, the operating temperature of ordinary high-alumina bricks is lower, about 1450°C to 1600°C, which means that Al2O3-C ramming mass has obvious performance advantages in high temperature environments.

Corrosion resistance comparison

In terms of corrosion resistance, Al2O3-C refractory ramming materials perform well, especially when facing oxidation reactions, high-temperature slag and alkaline substances, its carbonaceous components can effectively prevent slag penetration and extend the service life of the material. However, high-alumina bricks and other oxide-based refractory materials are prone to oxidation and melting at high temperatures, and their corrosion resistance is relatively inferior.

Service life

According to many industrial application cases, the service life of Al2O3-C refractory ramming materials in high-temperature metallurgical equipment such as electric furnaces and converters is about 30-40% longer than that of traditional refractory materials such as high-alumina bricks and magnesia-carbon bricks. This enables enterprises to significantly reduce the total cost of ownership and reduce equipment downtime and maintenance frequency.

Application scenario analysis

Al2O3-C refractory ramming material is widely used in metallurgy, petrochemical and glass industries due to its excellent comprehensive performance. In the steelmaking industry, it is mainly used for the lining of converters and electric furnaces, showing super high resistance to thermal shock and long-term resistance to slag erosion. For applications with lower high temperature resistance requirements, such as industrial boilers, high alumina bricks are a better choice due to their low cost.

in conclusion

In summary, Al2O3-C refractory ramming mass is superior to other refractory materials in many key performance indicators, especially in terms of heat resistance, erosion resistance and service life. For industrial equipment that needs to be used for a long time in a high temperature environment, choosing this type of ramming mass is undoubtedly a more economical and reliable decision.
