Product description of wear resistant castable
Refractory corundum wear-resistant castable is an amorphous refractory made of corundum as the main raw material, and then added with the required binder and additives. It is a kind of amorphous refractory widely produced and used at present. The fire resistance and wear resistance are more outstanding than other castables, and the aluminum content of corundum series castables is relatively high, so the use effect is also good.
Features of wear resistant castable
- Erosion resistance
- Good thermal strength
- High strength and wear resistance
- High density and low porosity
- High fire resistance
- Good peeling resistance
Application of wear resistant castable
- Furnace for chemical industry and construction industry
- Metallurgical furnace, heat treatment furnace
- Garbage incinerator, circulating fluidized bed boiler
