Product Description

    Brown Fused Alumina F24，F46,F54Abrasive Raw Materials For Vitrified Wheel .Brown Fused Alumina is fused and crystallized under the high temperature of above 2250°C with high quality abrasive bauxite as raw material.It is characterized by good self-sharpening and high grinding ability. Brown Fused Alumina can produce ceramic grinding wheel ,resin grinding wheel.And BFA could be used for abrasive,sandblasting and precision casting

    Brown corundum production process:
Break up the bauxite →add iron filings ,carbon smelting→cooling→break the brown corundum block→manual sorting→different grades of brown corundum
 
Brown fused alumina for refractory advantages:

1) No burst,no pulverization and crack in the using course of refractory

2) Refractory temperature is more than 1900°C

3) High quality bauxite as raw material
4) Very low amount of iron oxide
5) High purity
6) Low coefficient of linear expansion

Brown corundum for Abrasive SandblastingPrecision casting advantages:

1)Very low amount of iron oxide, suitable for non-ferrous blasting operations.

2) Sandblasting in the non-iron process.

3) High speed processing.

4) Not affecting the color of the processing cases.
