Product Description

Fire brick, refractory brick, insulation brick, insulating fire brick, insulation refractory brick, fire bricks, refractory bricks, insulation bricks, insulating bricks, insulating fire bricks, insulator, fire proof brick, lining brick, hot face bricks, cold face bricks,

JM series insulation refractory bricks with characteristics of little of impurities of iron and alkali metal of low temperature melts, good high temperature fire resistance, which can minimize the effects of reduction atmosphere effectively. Uniform structure, light weight, high cold crushing strength, good insulating performance.
White color low iron insulation refractory bricks which have high CCS and low liner change widely used as lining in various kiln and furnace.

Characteristics of our Mullite IFB(JM-IFB):
1) After shaping and sintering, cutting and grinding processing are done, drilling is necessary according to brick drawings.
2) Little impurities of iron and alkali metal
3) High temperature resistance
4) uniform structure and high cold crushing strength
5) Good thermal shock resistance, stable volume, good insulation performance in high temperature
6) Low thermal conductivity

Application:
Our mullite IFB can be used as a hot face lining directly exposed to the fire, as a backup insulation layer in iron and steel mills, non ferrous foundries, , petrochemical, ceramic, glass, cement and oil fired electric power generating plants.
