High aluminum poly light insulation brick ALO₂ content of more than 48%, mainly by mullite and glass phase or corundum together composed of light refractory material. Bulk density 0.4~1.35g/cm³. The porosity is 66% ~ 73%, the compressive strength is 1 ~ 8MPa, the fire resistance temperature is 1600 degrees, and the thermal shock resistance is good.

High-alumina poly-light thermal insulation brick, also known as high-alumina poly-light ball brick, is produced by poly-light burning loss method with super-grade blast charge as the main raw material, supplemented by appropriate admixture. The product has the advantages of high strength, good thermal stability, small change of reburning fiber, small thermal conductivity and so on.

1, high temperature and high strength;

2. Good thermal insulation performance;

3. Resistance to corrosion in various atmospheres;

4. Significant energy saving effect;

5. Excellent thermal shock stability.

high aluminum poly light brick uses:

High aluminum poly light brick has reached the international similar products to various technical indicators, is the current industrial kiln design must choose new materials. Widely used in metallurgy, machinery, ceramics and chemical industry furnace lining (not by the erosion of the solution) and insulation layer, it is an ideal energy-saving products. Its use temperature is below 1350°C.
