General Information of Insulating Fire Brick GJM26
Insulating fire brick GJM26 are produced by high purity alumina and low iron raw materials. A viariety of
To make our firebricks more energy and cost effective, we have different manufacturing methods for our insulating fire bricks casting and extruding method.
For insulating fire bricks GJM28,we choose the extruding method. Extruding insulating fire bricks have better strength and offering great performance in load bearing applications and in conditions where abrasion from mechanical abuse or flow of hot gases.
Characteristics of Insulating Fire Brick GJM26
Our insulating fire bricks exhibit the following characteristics:
Light weight and low thermal conductivity allows thinner furnace walls
Low heat storage results in rapid cooling and heating operation
Low iron and impurities to enhance reducing atmosphere
