chamotte insulating brick (NG0.5)

Detailed Product Description

The photo shows chamotte insulating brick NG series.

DOUBLE EGRET is the specialized manufacturer and exporter of insulation and refractory material in north of China with more than 10 years' history. Our brand CCE WOOL is well known in the world, enjoying good maket in Europe, America, Southeast Asia and Mid East.

Chamotte insulating brick, also named light clay brick,using chamotte as raw material, is made by adding combustible, gas evolution method, or foam method. Chamotte insulating brick is a kind of porous material with Al2O3 content 30-46%. The refractoriness is almost the same as fire clay brick. But compressive strength, slag resistance and corrosion resistance are much lower.

CHARACTERISTIC:

Low thermal conductivity, excellent thermal insulation.

Low thermal capacity: excellent conserve energy in batch operation kiln

Low impurity: The higher aluminum content made it still to maintain the good performance under the reducing atmosphere.

APPLICATION:

heat surface fireproof lining

other fireproof materials back lining

industrial furnace

electric furnace

metallurgical stove
