Sillimanite bricks are sillimanite mineral structured refractory bricks produced by high temp sintering method or even slurry casting method. So that they have very good temperature performance in furnace or kiln. If you need this refractory brick for sale, welcome to contact us for detailed information.
Sillimanite is definitely natural high grade refractory mineral, it features throughout low thermal expansion charge, good molten slag rust resistance and glass water corrosion resistance, excellent hot temperature abrasion resistance and consequently on. After high temp calcining, sillimanite will enhance into mullite and free of charge SiO2.
Sillimanite refractory bricks and mullite bricks have higher refractoriness under load in comparison with fireclay bricks. Sillimanite brick has compacted structure, when applied inside glass furnaces, glass chemical is not tend in order to form bubbles. So they are definitely suited for feeding canister, clay-based barrel, former block in addition to feeder bowl.
Sillimanite Bricks Manufacturing Process
Slurry audition method produced sillimanite bricks adopt natural sillimanite, produced mullite, high alumina clinker and so on because recycleables. Gypsum mould will be made in accordance with products forms, and slurry used intended for casting is prepared centered on technical parameters. Right after casting, green sillimanite bricks should be dried ahead of warm sintering.

Sillimanite Bricks Application
Sillimanite bricks application have much better physiochemical properties than large alumina bricks, they will be mainly used in a glass tank furnace throat, boost furnace lining, furnace tonsils, ceramics industry kiln home furniture and so on. Seeing that sillimanite brick has great temperature thermal stability, very good capacity glass liquid deterioration ., low pollution to a glass liquid, they are normally used at glass sector feeding canister, feeder, conduit drawing machine and also other gear, production efficiency are drastically improved.
