Product Description of Dry Pressed Insulating Refractory Brick Kiln Fired Clay Bricks Low Porosity Fireclay Bricks

Fireclay bricks are a type of refractory brick made from aluminum silicate materials. They have an alumina content of 30-40% and a melting point of up to 1690-1730 degrees Celsius. Fireclay bricks are made from kaolinite (Al2O3·2SiO2·2H2O) as the main mineral composition, with impurities of 6-7%, including potassium, sodium, calcium, titanium, and ferrous oxide. Fireclay bricks are classified as slightly acidic refractory materials that can resist acid slag and gas erosion.

Features of Dry Pressed Insulating Refractory Brick Kiln Fired Clay Bricks Low Porosity Fireclay Bricks

Fireclay bricks are highly heat-resistant ceramic bricks designed for use in high-temperature environments. Key features include:

1.High Heat Resistance: Can withstand temperatures up to 1,200-1,800°C (2,192-3,272°F).

2.Excellent Thermal Insulation: Low thermal conductivity for conserving heat.

3.Chemical Resistance: Resistant to chemical corrosion.

4.Abrasion Resistance: Endures wear and tear.

5.Low Porosity: Doesn't absorb water or liquids easily.

6.Dimensional Stability: Maintains shape under extreme heat.

7.Versatile: Used in steelmaking, glassmaking, and various industrial applications.

8.Customizable: Can be shaped to fit specific needs.

9.Cost-Effective: Offers good performance for the cost.

10.Long-lasting: With proper maintenance, provides a reliable solution for high-temperature environments.
