High-Alumina Insulating Special-Shaped Brick
Category:
Product introduction
This product is manufactured using rapid-foaming and setting technology, resulting in low bulk density, high compressive strength, a high load-softening temperature, tight dimensional tolerances, and excellent thermal stability. It boasts the lowest and most stable thermal conductivity among all existing insulating refractory bricks, making it widely suitable for insulation layers in various thermal-process equipment as well as for lining applications where there is no severe erosion or attack by high-temperature molten materials. By effectively reducing the overall weight of the furnace and enabling thinner furnace walls, this material enhances thermal efficiency, lowers energy consumption, improves working conditions, and delivers significant economic benefits.
