Packing: 1 MT big bag or 25kg paper bag *40 bags on one pallet ; As per customer’s requirement
Brown fused alumina for refractory advantages:
1) High quality bauxite as raw material
2) Refractory temperature is more than 1900°C
3) High hardness, good toughness
4) Very low amount of iron oxide
Brown aluminium oxide for resinoid grinding wheel advantages
1) Low coefficient of linear expansion
2)Without resillage, without rust
3)Good hydrophilicity
4)Good toughness and high hardness
In order to meet the demands of the refractory industry, We independently develop and produce RS Brown Fused Alumina whichis adoptedbymodern unique technology of smelting and processing under the universities and research institutes support.
RS Brown Fused Alumina is characterized by high purity, good crystal, strong fluidity, low coefficient of linear expansion ,goodcorrosion-resistance and so on. After practical tests by dozens of refractory manufacturers, RS Brown Fused Alumina can t burst. pulverise andcraze in the using course. In particular, its performance- -cost ratio is much higher than traditional Brown Fused Alumina, making RS Brown FusedAlumina become the best aggregate and padding of brown fused alumina refractory materials.
Remark: specification and size can be optimized by per customer' requirement
