Product Description

Product Description

Product Introduction:

Mullite Insulating Brick
Product Introduction:
Mullite light-weight brick are made from good quality and super-pure raw materials,with strictly classified fillings according to their grades.These fillings can form a uniform  pore structure after burnt during the process of manufacture.Bulk Density    0.5~1.25g/cm'.Working temperatures range from 1000ºC to 1600ºC.Each grade of products has unique design to meet different thermal, physicl and chemical demands.Each face of the brick is machined to the required accurate size.

Product Highlights:
- Low thermal conductivity: Hh series lightweight heat-insulating Bricks have an excellent feature of heat-insulation.
- Low heat capacity: Hh series lightweight heat-insulating bricks store very little heat because of their  characters of lightweight and low thermal conductivity,which causes good energy saving especially in batch operation.
- Low   content   of  impurities: Hh series lightweight heat-insulating bricks have high refractorieness with low content of iron and alkali-metal,High content of alumina enables them to maintain nice performances in reducing atmosphere.
- High hot compressive strength
- Accurate size
- The bricks can be processed into special shapes to avoid the joints and the number of bricks.
-Application:
Suitable for various industrial furnaces: Suspended ceiling,wall and heat insulation lining material of various  industrial  furnaces,suck  as  bell-type  furnace, heating furnace, cracking furnace, thermal treatment furnace, shuttle kiln,tunnel  furnace, roller kiln,enamel kiln,etc.

Usage of Corundum Mullite Bricks: mainly used in key parts of kilns in industries such as steel, electronics, petrochemical, non-ferrous, refractory materials, etc.
