N - 3a High Temperature Brick With 30%-48% AL2O3 / Fireclay Heat Proof Bricks

High Quality N-3a FireClay Bricks With 30%-48% AL2O3 Sell Well In Singapore

Multipurpose Fireclay brick manufactured by us takes clay clinker as aggregate and refractory soft clay as binding agent. It is a universal refractory products with 30%-48% AL2O3 content. The refractoriness fluctuates from 1580°C to 1700°C. The products fluctuates in a very wide range and the differences in production processes, thus its properties fluctuate within a wide range.

Fireclay bricks features:

1.Have good thermal shock resistance,

2.Large fluctuation range, generally more than 10 times (water cooling at 1100°C);

3.Coefficient of linear expansion of clay products; average line expansion between 20°C and 1300°C the coefficient is (4.5-5.8)×10-6°C-1;
4. The fireclay refractory material is a weakly acidic refractory product and its acidity increases as the SiO2 content increases;

5.It has a certain erosion resistance to the acid slag, and poor resistance to alkaline slag erosion.

Therefore, fireclay fireproof products should be used as lining for acid slag furnaces.
