Description:

 

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 

 

3) Good hydrophilicity

 

4) Good toughness and high hardness

 

 

Remark: specification and size can be optimized by per customer' requirement
