Refractory material Brown Fused Alumina

Refractory material brown fused alumina Our company owns a bauxite mine, a smelting factory and a processing factory, and we are a professional BFA manufacturer including mining, smelting, processing, inspection, selling and transportation. Now we have two 3150KVA tilting pouring electrical arc furnaces, the annual output reached 30,000 tons for brown fused alumina. Brown Fused Alumina is made by high-quality bauxite as main materal, fusing and purifying in a pouring electric arc furnace at a temperature of over 2200°c, and made into different grain size through crystal, choosing, crashing, magnetic, separating, screening, washing and acid cleaning, etc. It has the characteristics of high hardness, high toughness, resistance of high-temperature, anti-oxidation, corrosion resistance, etc. Chemical composition: Technical specificationBFA97BFA95SiO2<1.0<1.2Al2O3>97>95Fe2O3<0.3<0.3TiO2<1.6<3.0Na2O<0.1<0.2CaO+ MgO<0.7<0.8ZrO2<0.13<0.15Humidity<0.2<0.2Magnetic Iron<0.1<0.1Specific Gravity3.93gr./cm33.8gr./cm3
