Firebird Refractory Anchor Bricks are made from selected high-quality raw materials such as bauxite, andalusite, mullite, alumina, or silicon carbide, depending on the working temperature and atmosphere. These bricks boast key features including high strength, excellent refractoriness under load, and outstanding volume stability.
Manufactured to provide superior structural support and thermal insulation, our Refractory Anchor Bricks ensure long-lasting durability in demanding environments. They are essential for securing ceramic fiber modules, castable refractory linings, and other insulating materials in kilns, boilers, and furnaces.
Refractory Anchor Bricks are widely used in:
Cement Kilns: To anchor castable linings in rotary kilns, precalciners, and coolers.
Glass Furnaces: Offering durability and insulation in the high-temperature regions of glass furnaces.
Petrochemical and Refining: For securing linings in cracking furnaces, reformers, and gasifiers.
Steel and Metal Industries: In blast furnaces, hot stoves, and ladle furnaces to protect lining materials.
Power Generation: Used in boilers, incinerators, and thermal reactors for anchoring insulation materials.
