Description for Sillimanite Refractory Bricks
Sillimanite bricks 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.
Sillimanite Refractory Bricks Advantages
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.
Dimensions of Refractory Brick
The standard size of it is 230*114*65mm; and 230*114*76mm, 230*114*32mm, etc are also common used. Except for the common sizes, some special shapes could be customized according to the customers' requirements

Applications For Refractory Sillimanite Brick :
Sillimanite brick mainly used for the molding of liquid hole in glass pool kiln, blast furnace lining, furnace throat and ceramic industrial kiln furniture. The refractory materials based on natural sillimanite also have these advantages. Therefore, sillimanite refractories are widely used in metallurgy, chemical and building materials industries
Packaging : Packed by sea-worthy wooden pallet + shrink wrapped + carton
For example,Standard size of sillimanite bricks : 230x114x65mm
Shipping : 384pcs/plt x 18plts in one 20 feet container;
