Detailed Product Description

The photo tells us insulating brick in red color. It's the chamotte insulating brick.

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

Double Egret is the specialized manufacturer and exporter of refracotry and insulation material in north of China. Our products mainly include insulating brick, refractory brick, refractory castable, ceramic fiber products. For insulating brick, the production capacity is 300tons per month, including JM insulating brick and chamotte insulating brick, primarily export to UK, USA, ITALY, JAPAN etc.

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
Low impurity

APPLICATION:
Heat surface fireproof lining
Other fireproof materials back lining
Industrial furnace
Electric furnace
Metallurgical stove
