characteristics of fire clay bricks:
1,high density
2,good thermal shock resistance
3,excellent volume stability at high temperatures
Lightweight clay refractory brick is with a light weight, small thermal conductivity and high refractoriness. Its drawback is high air permeability, loose structure, low mechanical strength, anti-slag and poor anti-harmful gas erosion ability, easily to be damaged in long-term use. Therefore, the density of 0.4-0.8g / cm3 fireclay products are generally used as high temperature insulation components, the density of 1.0-1.3g / cm3 fireclay product as an insulation wall between industrial boiler pipe.
