High Alumina Refractory Firebricks

They are commonly used in boiler furnaces, combustion chambers, kilns, furnaces, incinerators, and other high-temperature industrial equipment. Grade selection depends on the specific service conditions.

Key properties include alumina content, bulk density, cold crushing strength, and apparent porosity. You can refer to the sample test certificate for the tested values.

Common sizes include 230 × 115 × 75 mm, 230 × 115 × 65 mm, 230 × 115 × 50 mm, and 300 × 150 × 75 mm. Custom sizes and shapes can also be manufactured to drawings.

Common grades include 40%, 50%, 60%, 70%, 80%, and 90% Al₂O₃. Higher alumina generally provides greater refractoriness, strength, and resistance to chemical attack.

Grade selection depends on operating temperature, mechanical load, abrasion, chemical exposure, and thermal cycling. The appropriate grade can be recommended based on the service conditions.
