High Temperature Resistance Brown Fused Alumina BFA Grain For Refractory Ramming
High Temperature Resistance Brown Fused Aluminuim Oxide BFA Grain 5-8mm For Refractory Ramming.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
In order to meet the demands of the refractory industry, we independently develop and produce RS brown fused alumina. Which is characterized by high purity,good crystal,strong fluidity,low coefficient of linear expansion,good corrosion-resistance and so on. RS Brown fused alumina could not burst,pulverise and craze in using course.
Brown fused alumina for abrasive SandblastingPrecision casting advantages:
1) Not affecting the color of the processing cases.
2) Sandblasting in the non-iron process.
3) High speed processing.
4) Very low amount of iron oxide, suitable for non-ferrous blasting
operations.
Brown fused alumina for refractory advantages:
1) High quality bauxite as raw material
2) Refractory temperature is more than 1900°C
3) No burst,no pulverization and crack in the using course of refractory
4) Very low amount of iron oxide
