Sillimanite Brick For Furnace Regenerator
1.Good structure.
2.High Heat Stability
3.Excellent thermal shock resistance.
4.Strong resistance to chemical attack.
Features:
The sillimanite brick is made of sillimanite minerals .After high temperature calcination,it become mullite and
dissociate silicon dioxide.Generally use high-temperature firing method and slurry casting method to produce.
1.Good thermal stability.
2.Strong resistance to chemical attack.
3.It is the first choice of stable material for glass forming.
Applications:
1.Widely used in glass furnace ,such as regenerator arch.
2.Mainly used in the blast furnace.
