Insulating Fire brick

Specifications

Insulation fire brick
Density:0.5, 0.6, 0.8, 0.9,1.0, 1.2, 1.3g/cm3
Temp:900-1300degree
Size: 230x114x65/75mm

CHARACTERISTIC:

Low thermal conductivity,excellent thermal insulation.

Low thermal capacity excellent conserve energy in batchoperation kiln

Low impurity. The higher aluminumcontent made it still to maintain the good performance under thereducing atmosphere.

Precise outlook size. Speeds up the masonry and building speed, thebrickwork joint thin also neat is consistent. Guaranteed masonry andbuilding body intensity high, the stability is high.

 

APPLICATION:

Heat surface fireproof lining or other fire-proofmaterials back lining thermal insulation
