Product description
Sillimanite bricks manufactured by CH Refractories are made of sillimanite minerals. Sillimanite is converted into mullite and free silica after high-temperature calcination. Generally, it is produced by high-temperature firing method and mud casting method. Its physical and chemical properties are better than high alumina bricks, with a refractoriness of 1770~1830℃ and a softening starting point under load of 1500~1650℃. It is mainly used for the forming of the flow hole of the glass tank kiln, blast furnace lining, furnace throat and ceramic industrial kiln furniture.
Application:
The Sillimanite bricks has good high-temperature thermal stability, resistance to glass liquid erosion and erosion, and little pollution to the glass liquid. It is suitable for the superstructure, feed channel, cover plate and molding parts of the glass kiln. It is also suitable for hot blast furnaces and blast furnaces in the steel industry.
