More details :
Light weight insulation Refractory castable is one of the unshaped refractory materials.It is made of refractory aggregate . refractory powder . binders and other additives. It is loose, No fixed shape,Has high liquidity, Casting and vibration molding,Can use directly or use after add appropriate water or other liquid. It is one of the new type refractory material of don’t need calcination.

thermal shock resistance castable

Thermal shock resistance refractory castable

This type product uses superior artificial materials as main raw materials and mix with superior combined binder and super micropowder . it has characteristics of excellent steady thermal shock , high refractoriness and high strength which could ensure the whole structure of CFB boiler liner and more suitable for the circumstance where temperature fluctuation is relatively large in the Ignition channel and water cooling chamber of CFB boiler . …


high strength wear-resisting castable

High strength wear-resisting refractory castable suitable

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. …
