High strength wear-resistant castable Product Features: Series of high-strength wear-resistant refractory castable, respectively high quality bauxite or corundum, silicon carbide and other aggregates according to different grades, and the introduction of a variety of powder, superfine powder, Emery and admixtures for admixture dispositions. Its main features are: high strength, erosion resistance, good thermal shock resistance and other characteristics, for use in a circulating fluidized bed boiler air distribution plate, put the dregs tube furnace and the furnace exit dense area, and import and export flue cyclone back to the feeder, cold slag and other structure is more complicated, and the vibration can stand die casting smaller parts. Working temperature about 900 ℃.
