|---|---|---|---|
In the high temperature state, the anti-crust refractory castable forms a glaze layer on the surface of the material, preventing the penetration of the glass phase in the cement raw material, thereby playing an anti-skinning effect. The anti-crust refractory material is mainlyused for the easy skinning of the cyclonepreheater cutting slope, rising flue, preheater cone and other parts.
