low thermal conductivity

High spalling resistance

For industrial ceramics, industrial furnaces

 

Light Weight Insulating Firebrick / Mullite Brick / High Alumina brick

 

Description:

Insulating Firebrick / Mullite Brick/ High alumina brick with light weight has high mini-porosity arranged in average, keep furnace wall low radiation.They can be used for hot face lining directly exposed to the heat or as a backup insulation layer.Light weight means the lowest thermal storage, it's quicker to heat and cool, and permit rapid cycle work.They are used for 800C~1500C 



Property 

Light weight and low thermal conductivity reduce the thickness of the insulating layer 
Maintain stable structural strength throughout ambient to maximum service temperature 
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; 
Customize any size and shape 
High spalling resistance 
High hot compressive strength 
Accurate dimensions 
Roller kiln 

 

Application

Rock wool products have the following application:

Lining of high-temperature kilns of industrial ceramics, industrial furnaces 
Annealing furnaces 
Galvanizing furnaces 
Heat-treating furnaces
