Dense Mullite castable refractory Cement kiln material 65% Al2O3 ISO9001 Certificate
Mullite castable refractory 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 content of Fe2O3 is controlled within a certain range (less than 1. 5%) cause it's the main impurity of mullite castable refractory, which is good for the product stability, improving the using performance.
Mullite castable refractory produced by us is widely used in cement kiln decomposition furnace, tertiary air duct and any other parts.
Mullite castable refractory features:
1, High cold crushing strength
2, Good resistance to erosion
3, 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.
4, Volume stability and high service temperature.
5, As for its outstanding using effect, it is the best and the most ideal castable for new dry process cement kiln.
