Refractory Wear-resistant Anchor Bricks are specially designed refractory components that combine excellent anchoring performance with superior wear resistance. Made from high-quality alumina-based raw materials such as bauxite and processed through advanced molding and high-temperature firing technology, these bricks feature high strength, excellent thermal shock resistance, and outstanding volume stability.
These anchor bricks are mainly used to secure refractory linings and protect furnace structures in high-temperature and high-abrasion environments. Their unique structural design enhances the bonding strength between refractory bricks, castables, and steel structures, effectively preventing lining deformation, falling, and damage caused by thermal expansion, mechanical vibration, and material erosion.
With excellent resistance to abrasion, high temperature, and chemical corrosion, Refractory Wear-resistant Anchor Bricks have been successfully applied in high-wear areas such as cement kiln preheaters, separators, high-temperature combustion chambers, boilers, and industrial furnace roofs. They help reduce external shell temperatures, extend furnace service life, and improve operational safety.

Product Features of Refractory Wear-resistant Anchor Bricks
- Excellent Wear Resistance: Refractory Wear-resistant Anchor Bricks are manufactured with high-quality alumina and bauxite materials, providing excellent resistance against mechanical abrasion, material impact, and high-speed airflow erosion. They are ideal for furnace areas exposed to continuous wear.
- High Temperature Resistance: With a refractoriness of up to 1790°C, these anchor bricks maintain stable physical properties under extreme temperature conditions. They prevent deformation, softening, and structural failure during long-term furnace operation.
- Superior Mechanical Strength: The cold crushing strength can reach 80 MPa, enabling the bricks to withstand heavy loads, thermal stress, and mechanical impact. Their high structural strength ensures reliable support for refractory linings.
- Outstanding Thermal Shock Resistance: These bricks are designed to handle rapid heating and cooling cycles. Their excellent thermal shock resistance reduces cracking and spalling caused by temperature fluctuations, improving furnace reliability.
- Stable Volume Performance: Low permanent linear change ensures dimensional stability during high-temperature operation. This helps maintain tight connections between anchor bricks and refractory castables, reducing the risk of lining failure.
- Strong Chemical Corrosion Resistance: The high alumina composition provides excellent resistance to slag, alkaline substances, acidic gases, and other corrosive media commonly found in industrial furnaces.
- Customized Shapes and Sizes Available: According to different furnace structures and installation requirements, customized anchor brick shapes, dimensions, and material grades can be provided to achieve better fitting and anchoring performance.
Applications
Refractory Wear-resistant Anchor Bricks are widely used in the following industrial applications:
- Cement Industry: Used in cement rotary kilns, preheaters, precalciners, separators, and high-temperature combustion chambers to anchor refractory linings, improve structural stability, and reduce abrasion caused by high-speed material flow.
- Steel and Metal Industries: Applied in blast furnaces, hot blast stoves, ladle furnaces, and heating furnaces to support refractory linings, withstand high temperatures, thermal cycling, and mechanical stress.
- Petrochemical and Refining: Suitable for cracking furnaces, reformers, gasifiers, and other high-temperature reactors where strong anchoring performance, wear resistance, and long service life are required.
- Power Generation Industry: Used in boilers, circulating fluidized bed furnaces, incinerators, and thermal reactors to secure insulation materials, protect furnace structures, and maintain long-term operational performance.
- Glass Furnaces: Installed in glass melting furnaces and other high-temperature zones to provide stable refractory support, improve lining durability, and extend furnace service life.
