Product Description
Lightweight High Alumina Insulation Brick For Energy-Efficient Furnaces 230*114*65mm
Lightweight high alumina bricks, or high-alumina insulating bricks, are critical components for thermal insulation in industrial kilns and furnaces. Engineered to minimize heat loss and enhance energy efficiency, they typically contain over 48% Al₂O₃. Primarily serving as backup insulation, they are installed behind the primary furnace wall, shielded from direct exposure to peak temperatures. This refractory material combines high compressive strength with low thermal conductivity to deliver reliable and effective thermal insulation.

Application in Furnace Design:
Lightweight high alumina bricks are strategically positioned in the insulating layer of a composite refractory lining system. Their role is critical in:
- Thermal Management: They act as a high-temperature insulator behind the primary working lining, drastically reducing heat flux to the furnace shell.
- Energy Conservation: By forming a reliable thermal barrier, they directly contribute to lower operating costs and improved energy efficiency of the thermal unit.
- Structural Protection: Their installation helps maintain a lower and more stable temperature on the furnace’s steel casing, protecting it from thermal damage.
- Typical Placement: These bricks are not in direct contact with the furnace charge or flame but are essential for the lining's overall thermal performance and longevity.
