CMAX refractory castable for electric power industry has an excellent performance in the important parts of the CFB boiler, due to the refractory castable’s advantages of being suitable to the high erosion environment.
CMAX refractory castable is also a good substitute for some refractory bricks to be much easier for construction.
Our refractory castable for electric power industry mainly has below characteristics:
Excellent chemical corrosion resistance
Excellent high strength
Excellent abrasion resistance
Excellent resistance to erosion
Excellent thermal shock resistance etc
Our refractory castable for electric power industry can be widely used in many part, such as:
Boiler furnace
Cyclone separator
Cold slag part
Ignition part
Other high erosion parts
CNBM has a good fame for the excellent performance of the CMAX refractory castable in electric power industry. CNBM also has rich experience in the electric power plants design and construction. We would like to assist you in product selection, system design, and installation techniques.
