Insulation bricks are classified under temperature between 1300ºC and 1700ºC, manufactured from high purity alumina clay by mixing, press-forming, drying, sintering and machining. Bricks contain carefully-graded organic fillers which are burned out during sintering to give a uniform controllable pore structure. This technique makes product feature low thermal conductivity and excellent heat insulation

 

Refractory Insulation brick can be used as a hot face lining directly exposed to the heat or as a backup insulation layer in iron and steel mills, non ferrous foundries, petrochemical, ceramic, glass, cement and oil fired electric power generating plants.

 

ADVANTAGES: 

Light weight and low thermal conductivity allows thinner furnace walls 
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 
Non standard sizes and shapes are available upon request
