High Strength Cement Unshaped Refractory Castable Wear Resistant For Furnace
High Strength Unshaped Refractory Castable Wear Resistant For Furnace
Description:
High strength wear resistant castable is mixed by corundum,high-quality bauxite clinker,silicon carbide as aggregate,all kinds of powder,ultra-fine powder,micropowder,alumina powder and additives as admixture with strict mixture ratios according to different varieties.its main characters are:high strength in normal and medium temperature,wear resistance and erosion resistance,thermal shock stability,etc.it is mainly used in the position of coal-fired circulating fluidized bed boilers,waster incineration furnace,lining of fluid-bed furnace etc,where are seriously abraded.
