introduction

High-alumina special-shaped bricks refer to refractory materials containing high aluminum components, which are widely used in many industrial fields due to their excellent pressure resistance. This article will discuss in detail the pressure resistance test results of high-alumina special-shaped bricks, and demonstrate their advantages in metallurgy, chemical industry and other industries through practical application cases.

Compressive performance of high alumina special-shaped bricks

Pressure resistance test data

The pressure resistance of high alumina special-shaped bricks has been tested many times. The following are some of the test data:

• Compressive strength: more than 50 MPa
• Bending strength: more than 10 MPa
• Thermal expansion coefficient: less than 1.0x10 ^-6 /°C

These data indicate that high-alumina special-shaped bricks can maintain structural integrity in high stress environments and exhibit excellent mechanical properties.

Stability and durability in high temperature environments

High alumina special-shaped bricks have excellent stability and durability in high temperature environments. The following are related performance displays:

• Refractoriness: over 1750°C
• High temperature volume stability: maintain constant volume
• Thermal shock stability: After 30 cycles of rapid cooling and heating, no obvious strength attenuation was found in the high-alumina special-shaped bricks

Application Cases

Application in metallurgical industry

In the metallurgical industry, high-aluminum special-shaped bricks are widely used in the construction and maintenance of steel smelting furnaces and ladle linings. Practical applications have shown that the use of high-aluminum special-shaped bricks can extend the service life of equipment and reduce downtime for maintenance.

Applications in the chemical industry

In the chemical industry, especially in the lining construction of high-temperature and high-pressure reactors, high-aluminum special-shaped bricks show extraordinary corrosion resistance and stability. For example, in a fluidized bed reactor lining project of a chemical plant, the stability and safety of the reactor were significantly improved after the use of high-aluminum special-shaped bricks.

in conclusion

High-alumina special-shaped bricks have been widely used and highly praised in many industries such as metallurgy and chemical industry due to their excellent pressure resistance and stability in high temperature environment. Their outstanding performance in practical applications provides a reliable choice for the industry and further promotes the efficiency and safety of industrial development.
