Refractory fire brick new product mullite lightweight insulation brick
1. Description
Mullite insulating brick, using high pure mullite as raw material, is made by adding alumina powder according to different type and then sintering in high temperature.
Classified by working temperature, there are JM-23,JM-26,JM-28, JM30, JM32.
These products can directly contact with fire, characterized with high temperature resistance, lightweight, low thermal conductivity, good energy saving effect,
specially suitable for cracking furnace, hot blast furnace, ceramic roller kiln, porcelain kiln extraction, glass crucible and various electric furnaces as lining.
It is an ideal product of energy efficiency and longevity.
