Anchor Brick

Description of Anchor Brick

Anchoring bricks, also known as anchor bricks, play a crucial role in various industrial applications, especially in furnaces and kilns. These bricks are designed with special shapes and structures. They typically have protrusions or hooks on their surfaces. These features are used to firmly attach refractory linings to the underlying supporting structures. The anchoring bricks prevent the refractory materials from dislodging due to thermal expansion, mechanical stress, or vibration during the operation of high – temperature equipment. Made from high – quality refractory materials, they can withstand extremely high temperatures, usually ranging from 1500°C to 1800°C. This high – temperature resistance ensures their long – term stability and effectiveness in maintaining the integrity of the furnace or kiln linings, thus improving the overall performance and lifespan of these industrial facilities.

Advantages of Anchor Brick

Exceptional High – Temperature Resistance

Anchor Brick can endure extremely high temperatures within industrial furnaces and kilns. This property prevents softening or melting, ensuring the refractory lining remains intact under harsh heat conditions.

Superior Mechanical Strength

Anchoring bricks are strong enough to firmly hold the refractory lining in place. They bear the weight and thermal stress of the lining, providing reliable support.

Buona resistenza agli shock termici

These bricks can withstand rapid temperature fluctuations without cracking or breaking. This is crucial as furnaces often experience sudden heating and cooling cycles.

High Dimensional Stability

Their dimensions remain consistent over time and under different temperatures. This ensures a perfect fit during installation and throughout the service life, maintaining the structural integrity of the lining.

Excellent Chemical Stability

Anchoring bricks resist chemical attacks from corrosive gases and substances present in industrial environments. This property helps to extend the lifespan of the refractory system.

Application of Anchor Brick

• • In steel – making furnaces: they secure the refractory linings, withstanding high temperatures and mechanical stress during the steel – making process.
  • In cement kilns：these bricks play a crucial role in supporting the kiln linings, ensuring continuous and stable operation.
  • In glass – melting furnaces: to fix the refractory materials, protecting the furnace structure. Their ability to firmly anchor refractory components makes them essential for maintaining the integrity and longevity of high – temperature equipment across various industries.
