Andalusite Refractory Brick For Flue-wall Compressive Strength: A Y60 Megapascals (Mpa )

Being the most respected organization guided by experienced and knowledgeable professionals, we are the famous Exporter, Manufacturer & Supplier of Andalusite Refractory Brick For Flue-Wall in Zhengzhou, Henan, China.
Andalusite refractory bricks have a number of advantages, it is strong creep resistance, creep is a measure of refractory bricks long-term resistance to high temperature load capacity, can cause premature softening of the refractory melt magazine on the creep effect is enormous, Even high-quality dense clay bricks will have about 5% Fe2O3, TiO2, R2O and so on.

Andalusite refractory bricks contain less impurities, so the creep value of 25 hours at 1300 a / 0.2MPa is 0.28%, only 20% -25% of the high quality clay brick with 42% Al2O385% bauxite high alumina brick is also low.

The high temperature strength is higher and the decrease is lower with the temperature and the other is the other characteristic of the red and theorite refractory bricks. The high temperature strength is related to the liquid phase formed by the refractory bricks at high temperature.

In addition, andalusite refractory bricks also have high temperature stability, thermal stability is better than the same Al2O3 content of other Al2O3-SiO2 refractory bricks, chemical resistance and other characteristics.
