Product Description

Blast furnace lining spalling with anti stripping high quality sillimanite bricks

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.

Sillimanite brick Advantage:
Our Sillimanite Brick: with high refractoriness, low creep and mechanical behavior under high temperature, high refractoriness under the load, good thermal shock resistance and slag resistance

1.Good thermal stability.
2.Strong resistance to chemical attack.
3.It is the first choice of stable material for glass forming.

Sillimanite brick Features:
1) Sillimanite bricks possess good refractory properties and good stability against
thermal shocking.
2) Mainly used in the blast furnace, wind pipe of blast heating cupola, lime kiln,discharging channel and cover board of glass melting kiln.
