Characteristics of Kerui Aluminum Bricks

High Refractoriness: High Al₂O₃ content and melting point, superior to fireclay bricks.

High Load Softening Temperature: Maintains structural strength under heavy loads at high temperatures.

Good Slag Resistance: Effectively resists both acidic and basic slags.

Chemical Erosion Resistance: Withstands corrosion from molten metals and slags.

High Hot Strength: Excellent mechanical strength and abrasion resistance at elevated temperatures.

Industrial Applications of Kerui Alumina Fire Bricks

In general, alumina bricks composition is bauxite, clay, and other raw materials. It is a high-temperature resistant brick. Among components, one of their main components is alumina. It has a melting point of 2050°C (3722°F). So, aluminum fire bricks have a refractoriness of over 1750°C (3182°F). So, this feature enables them to withstand extreme temperatures. Therefore, it is widely used in the following industries.
