High Refractoriness Wear resisting Castable for Slag Cooler of Easy To Wear Erosion
Description:
Scientific use of optimized particle gradation, powder, particle shape and other factors, together with a small amount of dispersant (water reducing agent) and appropriate amount of retarder and other additives made of admixture.
Features:
01:Good thermal shock stability
02:anti-peeling, abrasion resistance
03:acid-resistant medium erosion.
Application:
Mainly used for circulating fluidized bed boiler combustion chamber, separator and flue and other parts of the easy to wear erosion.
