Sillimanite Bricks Manufacturing

Sillimanite bricks is mainly firebrick made of siliconite minerals. Sillimanite is converted into mullite and free silica after calcining at high temperature. It is to use high temperature to burn commonly and mud pouring method production.

The physical and chemical properties of sillimanite refractory brick are better than that of high aluminum brick. The refractoriness is generally 1770℃~1830℃. The starting point of its load softening is generally 1500℃~1650℃. It is mainly used for the forming of liquid flow hole of glass pool kiln, furnace lining, furnace throat and ceramic industrial kiln.

Sillimanite is a kind of high-duty refractory, it has the characteristics of low thermal expansion rate, resistance to corrosion of metallurgical slag and various glass liquids, good high temperature wear resistance and so on. In addition, the sillimanite products of the binder its physical and chemical properties are the best close to natural sillimanite, especially the chemical composition and thermal expansion coefficient, and natural sillimanite is basically consistent, relatively speaking, high aluminum binding agent can meet these requirements, so choose high aluminum binding agent.
