High Hardness Precision Casting Materials Brown Aluminium Oxide Powder
Brown Fused Alumina is fused in the electric-arc furnace under the high temperature of above 2250°C with high quality bauxite as raw material and matched by the carbon material and scrap iron .The degree of refractory is more than 1850°C.
Brown fused alumina melt film precision casting sand is the latest corundum products self- developed by RuiShi Companytomeetemeedemands. Based on the production of the brown fused alumina and with special tehology, it is produced by the careful oganizincd eresearchers. The quality has reached the advanced level of similar foreign products through laboratory tests and productioninpracticeofdozensof casting enterprises. And some performances of it can be adjusted or showcased according to the customers' requirement. Theprecisioncatiosand of RuiShi Brand has high refractorinesss, low thermal expansion cofficient, good thermal stability, strong air permebilit,higitensty,easto shell, high casting finish.It can substitute Zirconia sand (powder) its price is only half of zirconia sand (powder), and the recovery ratioishighaswell.It can be mainly applied to the melt films and silicasol technology of jewelry, handicrafts, stainless steel products, watches, glasses, aluminumdiecasting industries, and can be processed in line with the demands of the clients.

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
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.
