Anchor Brick is a special type of brick used in industrial furnaces and kilns. It is mainly used to fix and support the refractory lining to prevent it from falling off. Made of high – temperature – resistant materials, it has good heat resistance and mechanical strength. It can effectively improve the stability and service life of the furnace lining.

Anchoring bricks have several characteristics. They possess high strength and good heat resistance, which enables them to withstand high temperatures. They also have excellent anchoring performance, ensuring firm connection with the substrate. Moreover, they have certain wear – resistance and corrosion – resistance, contributing to a long service life.
Anchoring bricks find wide applications in industrial settings. 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. They are also used 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.
