Brief description
1. Can contact with the flame directly
2. High Refractoriness,
3. High insulation
4. Low thermal conductivity
5. Significant energy-saving effect
Typical Application
Light weight brick can be used as heat surface refractory lining or other refractory material backing heat insulating layer, used in melting furnace, firing kiln, flue, refining device, heating device, regeneration unit, gas furnace and pipeline, soaking furnace, annealing furnace, reaction chamber and other industrial thermal equipment.
Advantage of Mullite Light- weight Insulating Brick
Mullite Light- weight Insulating Bricks are made of high pure materials, fired at high temperature by advanced technology, with the advantages of high strength, high compression resistance, good thermal shock resistance, good performance in high temperature, good thermal conductivity, good erosion resistance and so on. Widely be used for linings of furnace in industries.
