Red 230*114*65mm Anti-erosion Fireclay brick Universal kiln refractory material
Fireclay brick 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.
