The composition and Application of white fused alumina
It is made of industrial alumina after being melted at a high temperature above 2300℃ in an electric arc furnace and then cooled. The main component is aluminum oxide (Al2O3) with a content of more than 98% and contains a small amount of iron oxide, sodium, and other ingredients. It is white, after crushing and shaping, magnetic separation to remove iron, and sieving into various particle sizes. Its texture is dense and high in hardness. , The grains form sharp horns. Because it is formed through high-temperature smelting, it is determined that it has high wear resistance and fire resistance.
Application of white fused alumina: white fused alumina abrasive is suitable for surface beautification treatment of various high-end products, crafts or hardware, etc. Fine white fused alumina can be used as the first for polishing and grinding. white fused alumina can also be used as consolidation and coating abrasive tools, wet or dry or spray sand, suitable for ultra-precision grinding and polishing in the crystal, electronics industry and making high-grade refractory materials. Commonly used sandblasting models are 16#46#60#80#100#120#150#180#200#220# etc.
In addition, white fused alumina is suitable for processing hardened steel, alloy steel, high-speed steel, high-carbon steel, and other materials with harder hardness and higher tensile strength. It is also an ideal raw material for making large-scale ladle castables, medium and high-grade iron trough castables, gunning materials, bottle blanks, and other unshaped refractory materials.
Zhengzhou Yufa Abrasives Group has a history of producing high-quality alumina for more than 30 years.
