Insulating Fire Brick ranges a wide temperature 2300F-2600F-2800F-3200F, they are widely used in many kinds of industrial furnace insulating linings.

Mullite Insulating Firebricks Characteristics and Advantages: 
 
1. Lower content of iron, alkaline and impurities, good high temperature properties. 
2. Homogeneous structure, light weight, energy saving because lower heat storage in the furnace during cooling cycles. 
3. High strength, good thermal shock resistance under high temperature. 
4. Precise sizes due to grinding and shaping after sintering, which meets the requirement of construction. 
5. Max service temp: Up to 1730C 
 
NR Heat Insulating brick is in accordance with ISO9001 Standard. 
 
Typical Application
1)  Lining of high-temperature kilns of industrial ceramics, industrial furnaces under 1650C of petrochemical, metallurgy and machinery industries
2) Lining of hot-surface of industrial furnaces as carbon furnace, cracking furnace, heating furnace for oil refining, roller kiln, tunnel kiln.
3) Back lining insulating layer of industrial furnace as glass tank kiln.
4) Atmosphere furnace.
