General Information of Insulating Fire Brick GJM28

 

Insulating fire brick GJM28 are produced by high purity alumina and low iron raw materials. A viariety of shapes are available.
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 GJM28


The organic fillers, which are mixed in the materials and then burned out during sintering, give our insulating fire bricks a uniform controllable pore structure. The insulating fire bricks exhibit the following characteristics:
Light weight and low thermal conductivity allows thinner furnace walls
Maintain stable structural strength throughout ambient to maximum service termperature
Low heat storage results in rapid cooling and heating operation
Low iron and impurities to enhance reducing atmosphere
High thermal shock resistance in preventing spalling


Typical Application of Insulating Fire Brick GJM28


Ceramic shuttle kilns
Metal heat treatment furnaces
Steel billet reheating furnaces
Oil refrinery heaters
Laboratory furnaces
Backup insulation for all furnaces
