High strength Mullite castable refractory for Cement kiln thermal shock resistant
refractory material
High-strength mullite castable refractory for cement kiln uses high-quality mullite as main raw material, Al2O3 content indicators for more than 65%, in addition, added to cement, silica powder, wear-resisting material, and other auxiliary materials. The main impurity of high strength mullite castable refractory used in cement kiln is iron oxide. According to the actual situation of mullite raw materials in China, 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.
Good thermal shock resistance is an outstanding advantage of high strength mullite castable. Good thermal shock resistance is the necessary premise that make good use effect, the set of test program of thermal shock resistance (1100 ℃, water cooling) is to highlight the performance of high-strength mullite refractory castable used in cement kiln.
High-strength mullite refractory castable, 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.
