Description
High strength high alumina refractory castable is made of super high alumina clinker, composite binders and adhesives. The products are featured with high strength, good wear resistance, permeability resistance, erosion resistance, good mechanical properties, convenient construction, etc. It is commonly used in top of CFB boiler furnace, rear wall, etc.
This series of castable to refractory high alumina raw materials is mainly combined with the use of new powder technology and efficient compound chemical additives. load softening in high temperature, long service life, easy for construction and other characteristics, it has a has a significant effect on improving the insulation, reducing heat loss, reducing the environmental operating temperature.
