High Alumina Poly Light Insulation Brick 230*114*65 Mm Insulating Brick Light Weight For Kiln Insulation Lining Energy-Saving

High Alumina Poly Light Insulation Brick also known as Light Weight High Alumina Brick and high-aluminium heat insulating brick, Light weight high alumina bricks contain more than 48% alumina oxide, less than 2% Fe2O3 Content. The refractory temperature of this kind of brick can reach 1770 degrees, and the usable temperature can reach 1550 degrees. This brick has many advantages such as small volume density, high porosity, high mechanical intensity, good insulation effect, and long service life. It is a kind of essential refractory for energy saving and temperature preservation for various industrial kilns & furnaces.

Advantages:

1.Lightweight & Strong: Low volume density reduces structural load while maintaining high compressive strength

2.Energy Efficient: Fundamentally reduces heat loss, leading to direct fuel savings.

3.Excellent Insulation: Low thermal conductivity and high porosity ensure outstanding heat preservation.

4.Cost-Effective: A lower-price refractory option that reduces both construction and long-term operational costs.

5.High Refractoriness: Can withstand temperatures of 1650-1800°C, suitable for various atmospheres.

6.Superior Stability: Good thermal shock resistance, chemical stability, and strong resistance to corrosive gases and slag.

Application:

1.Ceramic Tunnel Kilns, Roller Kilns, Shuttle Kilns

2.Various Thermal Equipment & Heat Treatment Linings

3.Furnace Lining and Insulation Layers

4.Heating Furnaces & Coking Furnaces in the Iron and Steel Industry

5.Energy Conservation: By forming a reliable thermal barrier, they directly contribute to lower operating costs and improved energy efficiency of the thermal unit.

6.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.

7.Thermal Management: They act as a high-temperature insulator behind the primary working lining, drastically reducing heat flux to the furnace shell.
