Product Description

Characteristics of our JM INSULATING FIRE BRICK--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.
