High-strength wear-resistant castable product categories: high-strength wear-resistant castable GL-160 high-strength wear-resistant castable GL-135 high-strength wear-resistant castable GL-130 Product Description: Lego high-strength wear-resistant casting material, using high-quality or high-quality high-alumina corundum bauxite clinker, aggregates such as silicon carbide, and the introduction of a variety of powder, superfine, Emery and admixtures for admixture preparation; Macleod patented formula designed with wear minimal loss, high strength, arbitrary shape can control, integrity, simple construction, good performance, due to the addition of polymer to a solid layer of concrete bonding, for a construction site abrasion requirements is the preferred material. 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, corundum powder and additives for blending material 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 slag tube furnace and the furnace exit dense area, cyclones and import and export flue back to the feeder, cold slag and other more complex structure that can stand and vibration smaller die cast parts. Operating temperature is about 900 ℃.
