Alkali resistant castable is a kind of acidic fire-resistant aluminum casting material. At 1250 ℃, the surface crust of alkali resistant castable can form anti-erosion protection layer. The layer can effectively prevent the lining to be erosion and infiltration in the high temperature when cement kiln feed materials. Because of its high-intensity, low-density advantages, Alkali-resistant casting material widely used in cement kiln preheated site.
