Product Description Product DescriptionIndulge in the excellence of Brown Fused Alumina, also celebrated as Brown Aluminum Oxide, a top-tier synthetic mineral famed for its extraordinary hardness and unrivaled wear resistance. Crafted through an intricate procedure involving the fusion of bauxite, iron filings, and anthracite, all within a high-temperature electric arc furnace, it undergoes a sophisticated process of cooling, crushing, and screening. This ensures that every particle boasts superior quality. The exclusive physical and chemical properties of this product make it indispensable across a vast array of industrial applications, delivering peak performance and long-lasting durability.TYPICAL CHEMICAL ANALYSISAl2O399.54%Na2O0.23%SiO20.06%Fe2O30.06%PHYSICAL PROPERTIESColorBrownShapeAngular grain shapeCrystal FormAlpha aluminaSpecific Gravity3.95Hardness2150 Knoop scaleMagnetic Material0.00%Production ProcessEmbark on a journey through the intricate and artful creation of brown fused alumina (BFA), a masterpiece of engineering. This multi-stage process is a symphony of precision, seamlessly integrating raw material preparation, fusion, cooling, crushing, and thorough classification. Join us for an enlightening dive into this extraordinary process:Raw Material Preparation:Bauxite: The cornerstone of our premium production, handpicked bauxite, brimming with rich alumina (Al2O3) content, guarantees superior quality and minimal impurities, setting the stage for unparalleled excellence.Iron filings or scrap iron: Strategically infused into the mixture to act as a catalyst in the reduction process during fusion, significantly enhancing efficiency and performance.Anthracite coal: This crucial reducing agent is an integral part of the fusion process, delivering powerful results.Fusion:Electric Arc Furnace (EAF): The meticulously prepared blend is introduced into the electric arc furnace, where temperatures reach an astonishing 2000-2200°C (3632-3992°F), thanks to electric arcs from carbon electrodes, sparking the transformative journey.Reduction and Fusion: At these intense temperatures, bauxite's alumina gracefully melts and reacts with the carbon of anthracite to produce molten alumina. This process effectively segregates and reduces iron and other impurities.Cooling:Cooling the Molten Alumina: Expertly poured into molds or onto the cooling floor, the molten alumina undergoes controlled cooling, which is pivotal in creating the ideal crystal structure and desired size.Formation of Ingots: As cooling continues, the material solidifies into magnificent ingots or blocks, heralding the birth of illustrious fused alumina.Crushing and Grinding:Primary Crushing: The resolute cooled ingots face their initial transformation, broken down by powerful jaw crushers or similar robust machinery, preparing them for further refinement.Secondary Crushing and Grinding: Here, the material is meticulously ground and crushed to smaller sizes through cone crushers, roll crushers, and ball mills, pursuing the perfect particle size with unwavering precision.Magnetic Separation:Removing Metallic Impurities: The finely ground material undergoes magnetic separation, expertly eliminating iron particles and other metallic impurities, ensuring pristine purity.Sieving and Classification:Particle Size Distribution: The refined alumina is systematically sieved and classified into diverse grades based on particle size. Utilizing precision vibrating screens and air classifiers, we achieve exacting standards.Quality Control: Each batch is subjected to stringent testing for chemical composition, particle size distribution, and other quality metrics, assuring compliance with industry standards and delivering exceptional quality.ApplicationBrown fused alumina stands as a titan in various industrial sectors, revered for its extraordinary hardness, unmatched toughness, and a lofty melting point, making it an essential material across the board:Abrasives: This formidable component is pivotal in crafting grinding wheels, sandpaper, blasting media, and a host of other elite abrasive products, elevating quality and performance.Refractories: Indispensable in the creation of refractory bricks, castables, and a suite of resilient materials engineered to endure and excel under extreme temperatures.Surface Preparation: Perfectly suited for cleaning, deburring, and preparing surfaces, it finds a home in metalworking, automotive, and other meticulous industries requiring precision.Ceramics: This vital ingredient enriches ceramic products, endowing them with superior durability and thermal shock resistance, guaranteeing enduring performance and reliability.Detailed Photos Product ParametersGRAIN SIZES AVAILABLE (F) Discover the unmatched precision of our Advanced Brown Fused Alumina Sanding Blocks.
