Brown fused alumina slag-fesi During fusion process of brown fused alumina, the iron and metal content(mainly ferro and silicon)settle at the bottom of the arc furnace because of their higher density. After cooling down, it seperated from brown fused alumina whose content is aluminium oxide(al2o3). We select the settled metal part, crush and grade it into grains suitable for various industrial purposes. Its main content is ferro and silicon and can replace some fesi. We call it brown fused alumina-fesi. So the manufacturing process of brown fused alumina slag fesi is different from normal fesi. Because silicon is easy to react chemically with oxygen to become silicon oxide, it is used as deoxidizer in steel making industry. Silicon oxide(sio2) also produce a lot of heat, so can improve the temperature of steel. Fesi is also widely used in low alloy structural steel, spring steel, bearing steel, heat resistant steel etc. Its ferro content is typically 76%-80% and silicon content 13%-17%. Sizes can be made according to customer quest, common sizes are 0-10mm, 0-25mm etc. Applications of brown fused alumina slag-fesi Because of its hardness, it's used for sand blasting, rust removal, cleaning, polishing etc. Deoxidizer in steel making industry to improve strength, hardness and density of steel. Used as inoculant to help graphite precipitation Used as reducing agent in steel alloy industry. Newly development products like mineral processing, lithium ferro battery etc.

White fused alumina is made from high quality alumina by being melted above 2000°C in the electric arc furnace. It is characterized by high purity, great self-sharpening, acid and alkali resistance, high temperature resistance and stable thermal performance. Its hardness is a little higher than brown fused alumina. It is with low toughness, great grinding ability, small heat and high efficiency. White fused alumina can be made into all kinds of abrasives, suitable for grinding high carbon steel, high speed steel, stainless steel and other fine-grained abrasives; it can be also used for precision casting and high-refractory materials.

Pink fused aluminium oxide Pink fused alumina, also called pink fused aluminium oxide, chromium aluminum oxide, abbreviated as "pa", belongs to the group of artificial corundum. It's made from fusion of high purity alumina powder and chromium oxide in electric arc furnace. Because of its chrome content, it's a pink color material. Its main content is aluminium oxide(al2o3), with little content(about 0.7% chromium oxide and about 0.3% sodium oxide(na2o). Pink fused aluminium oxide is a hard, tough, self-sharpening, low magnetic, coarse grits, pure and clean abrasive material. Compared to white fused aluminium oxide, it has similar hardness, while better strength and cutting side. It's widely used in production of vitrified grinding wheel, resinoid grinding wheel, cutting discs, grinding head and other abrasive tools, also for sandblasting abrasvies, polishing, free grinding, cutting etc. Physical and chemical properties True gravity: ?3.9 g /cm3 Bulk density: 1.40-1.91 kg / m3 Mosh hardness: 9 Color: pink, light purple Melting point: 2200 celcius degree Sizes: f8-f220 Applications of pink fused aluminium oxide Production of ceramic and vitrified grinding wheel Grinding head and other bonded abrasives and coated abrasive tools Refractory bricks, glass oven and other refractory materials Free grinding and polishing on precision devices, mahinery parts, ceramics, precision casting etc. Clean, sand blast, polish, rust remove metal and non-metal parts

ight lower toughness comparing with brown fused alumina. It is also characterized by its high purity, acid and alkali resistance, good thermal stability. It¡¡¥s the high grade refractory materials. Applications Dedicated lines produce products for different applications. White fused alumina is highly friable and hence used in vitrified bonded abrasives products where cool, fast cutting action is essential and also in the manufacture of high purity alumina refractories. Other applications include use in coated abrasives, surface treatment, ceramic tiles, anti-skid paints, fluidized bed furnaces and skin / dental care.
