The andalusite mullite refractory brick is made of andalusite , and is added with a powder of sillimanite powder, mullite powder, etc., The binder is added in proportion, and is prepared by mixing, kneading, molding, and drying at a high temperature. Usage of andalusite mullite refractory bricks in hot blast stoves: hot blast stove wall, checker brick, furnace top, combustion chamber ( andalusite low creep series)
1. High temperature resistance, abrasion resistance and corrosion resistance.
2. Good thermal shock resistance.
3. Low creep rate.
4. High refractoriness under load .
5. Reduce harmful impurities
6,Good hot peeling resistance.
