High strength wear-resisting refractory castable

High strength wear-resisting refractory castable 

It is very complex when working inside the CFB boiler , the materials in circulation system flow high with big volume. So it requires using high strength refractory and wear-resisting materials on the liner of boiler. High strength wear-resisting refractory castable is mainly made up of corundum ,carborundum and the stunts burned bauxite, matched with superfine powder and composite additive. …
