    High Heat Light Weight Bricks​​​​​ generally refer to refractory bricks with a density less than 1.3 g/cm3. Due to the characteristics of low density, high porosity, small thermal conductivity, good thermal insulation and certain compressive strength, light-weight refractory bricks have been widely used in heat treatment equipment.


    High Heat Light Weight Bricks​​​​​  is also known as high aluminum insulation brick. Lightweight refractory material with alumina content above 48%, mainly composed of mullite and glass phase or corundum. The bulk density is 0.4 to 1.35 g/cm3. The porosity is 66%~73%, and the compressive strength is 1~8MPa. Good thermal shock resistance.


    The materials of ordinary light-weight heat-resistant refractory bricks are clay, high-alumina high-strength floating bead bricks, low-iron mullite, high-aluminum poly light-insulating refractory bricks, and diatomaceous earth heat-resistant refractory bricks.

    For strength products, high-quality plate-like corundum and mullite are used as aggregates, sillimanite composite is used as a matrix, special additives and a small amount of rare earth oxides are mixed, and then subjected to high-pressure molding and high-temperature firing.




•Resistance to High temperature, Resistance to erosion, resistance to abrasion

  • Nonferrous Metal Furnace
  • Rotary & Shaft Kiln
  • Various Incinerator
  • Reheating Furnace
  • Permanent Lining For EAF Ladle
