Insulation fire brick

Detailed Product Description

The photo shows insulation fire brick in carton package, being loaded in the container. This brick is chamotte insulating brick, red color.

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. Our brand is CCE WOOL , and OEM is also available.

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
