Sillimanite bricks Introduction
Sillimanite bricks are refractory bricks made of sillimanite minerals that are made via slurry casting or high temperature sintering.
For use in high temperature furnaces like blast furnaces, hot blast stoves, lime kilns, glass melting furnaces, and others, sillimanite bricks are made from sillimanite minerals using the high temperature firing method or slurry casting. These high-quality refractory bricks have many outstanding features, including high temperature wear resistance and high strength.

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 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 bricks have better physiochemical properties than high alumina bricks, they are mainly used in glass tank furnace throat, blast furnace lining, furnace throat, ceramics industry kiln furniture and so on. As sillimanite bricks have good high temperature thermal stability, good resistance to glass liquid corrosion, low pollution to glass liquid, they are usually used at glass industry feeding canister, feeder, tube drawing machine and other equipment, production efficiency are significantly improved. Sillimanite bricks series products mainly include: feeder bricks, feeding canister, rotating tube, feeder nose, feeder bowl, former block, slag skimmer block, shutter block, front arch bricks, back arch bricks, feeder nose cover, burner nozzle bricks, cover plate and so on.
