Mullite Castable refractory for Cement kiln Dense thermal shock resistant 2.45g/cm3
Mullite castable refractory for cement kiln uses high-quality mullite as main raw material, added to cement, silica powder, wear-resisting material, and other auxiliary materials. Al2O3 content is more than 65%, The main impurity of high strength mullite castable refractory used in cement kiln is iron oxide, the content of iron oxide is controlled within a certain range (less than 1. 5%), which is good for the product stability, improving the using performance.
Mullite castable refractory features:
1, Good thermal shock resistance, this is an outstanding advantage of high strength mullite castable that make good use effect. Thermal shock resistant at 1100℃ water cooling, can reach more than 25 times.
2, High cold crushing strength
3, Good resistance to erosion
4, Volume stability and high service temperature.
Mullite refractory castable application
As for its outstanding using effect, it is the best and the most ideal castable for new dry process cement kiln. And it’s widely used in cement kiln decomposition furnace, tertiary air duct and any other parts.
