White fused alumina(WFA) is made of industrial aluminum oxide powder, which is smelted at a high temperature above 2000 ° C in electric arc and then cooled. After grinding and shaping, the iron is removed by magnetic separation and screened into various particle sizes.
White fused alumina(WFA) is made of industrial aluminum oxide powder, which is smelted at a high temperature above 2000 ° C in electric arc and then cooled. After grinding and shaping, the iron is removed by magnetic separation and screened into various particle sizes. Hardness is slightly higher than brown fused alumina, toughness is slightly lower, high purity, good self-sharpening, strong grinding ability, low calorific value, high efficiency,acid and alkali corrosion resistance, high temperature and thermal stability.It is suitable for grinding high speed steel, high carbon steel and so on.Bubble Alumia Bricks use Bubble Alumina, Tabular Alumina and White Fuse Alumina as raw materials. It has very high refractoriness and can work as working lining for some high temperature industrial furnaces. As the low thermal conductivity compared with corumdum bricks, it is an energy saving and green high end refractory materials.
It is widely used in consolidation abrasive, coated abrasive, polishing and precision casting industries. Moreover, white fused alumina is refined and crystallized by electric melting. It is a kind of advanced refractory material with good heat stability and high temperature resistance.
