Description for Sillimanite brick:
Sillimanite brick are sillimanite mineral based refractory bricks produced by high temperature sintering method or slurry casting method. Sillimanite bricks manufacturing have very good high
temperature performance. Sillimanite is natural high grade refractory mineral, it features in low thermal expansion rate, good molten slag corrosion resistance and glass liquid corrosion resistance,
excellent high temperature abrasion resistance and so on. After high temperature calcining, sillimanite will transform into mullite and free SiO2. Sillimanite bricks and mullite bricks have higher
refractoriness under load compared with fireclay bricks. Sillimanite bricks have dense structure, when applied in glass furnaces, glass liquid is not tend to form bubbles. So sillimanite bricks are
definitely suitable for feeding canister, clay barrel, former block and feeder bowl.
Advantages of Sillimanite brick:
Sillimanite brick ,With low thermal expansion rate, sillimanite brick not only have good resistance to metallurgical slag and various glass liquids, good wear resistance at high temperature. But
also have good thermal stability at high temperature, less pollution to molten glass and high refractoriness under load.
1. Good thermal stability, low thermal expansion rate;
2. Slag has good corrosion resistance;
3. Body dense, resistant to glass corrosion;
4. High temperature resistance;
5. High softening temperature under load.
