Get PriceSOME PRINCIPLES GOVERNING THE PERFORMANCE OF REFRACTORY
The erosion resistance of a fired castable to the cutting acting of solid particles suspended in a gas (as in fluidized-bed reactors) depends chiefly on the properties of the binder. The aggregate plays a less important part but it must have adequate physical properties and a large maximum size of particle is unfavourable to erosion resistance.
