Red Fireclay Fireproof brick special shaped 30~48% Al2O3 refractory brick for
industrial kilns
Fireclay FireProof bricks are one of the main varieties of aluminum silicate products. They are refractory products with 30% to 48% AL2O3 content made of clay clinker as aggregate and refractory soft clay as binding agent.
The properties of Fireclay FireProof bricks fluctuate within a wide range. This is due to the fact that the
chemical composition of the products fluctuates in a very wide
range (fluctuations in the AL2O3 content range from 30% to 48%) and
the differences in production processes. The refractoriness
fluctuates from 1580°C to 1700°C;
Fireclay FireProof bricks have good thermal shock resistance, large fluctuation range,
generally more than 10 times (water cooling at 1100°C); 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.
The fireclay fireproof material is a weakly acidic refractory
product and its acidity increases as the SiO2 content increases. 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.
