Product Description Product DescriptionBrown Fused Alumina, also celebrated as Brown Aluminum Oxide, stands as a beacon of excellence among synthetic minerals, renowned for its unmatched hardness and exceptional wear resistance. This premium-grade material is meticulously engineered through an advanced and sophisticated process involving the fusion of bauxite, iron filings, and anthracite in a high-temperature electric arc furnace. Post this, the material undergoes a thorough cooling, crushing, and screening process, ensuring it surpasses the highest quality standards. Its outstanding physical and chemical properties make this product indispensable for a myriad of industrial applications, promising unrivaled performance and enduring durability, making it a choice material for those seeking excellence.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 captivating journey into the intricate world of brown fused alumina (BFA) production, where precision meets artistry at every turn. This remarkable process unfolds through a series of meticulously orchestrated stages: from the careful preparation of raw materials to the grand finale of systematic crushing and classification. Each step reveals the mastery and craftsmanship dedicated to creating this exceptional material.Raw Material Preparation:Bauxite: A crucial element at the heart of our production, this high alumina (Al2O3) content material is meticulously chosen. Our rigorous selection process ensures unmatched purity and quality, forming the foundation for exceptional results.Iron filings or scrap iron: These materials are seamlessly incorporated into the blend, significantly enhancing the reduction process during fusion, thereby elevating both efficiency and the quality of the final output.Anthracite coal: Acting as an essential component in the fusion process, anthracite coal serves as a powerful reducing agent, facilitating vital transformations with unparalleled effectiveness.Fusion:Electric Arc Furnace (EAF): Our expertly formulated mixture is introduced into the Electric Arc Furnace, where temperatures escalate to an astounding 2000-2200°C (3632-3992°F). Here, under the influence of electric arcs generated by carbon electrodes, the transformation process begins.Reduction and Fusion: In this searing heat, bauxite's alumina liquefies as it interacts with carbon from anthracite, resulting in the formation of molten alumina. Impurities, including iron, are effectively reduced and separated, ensuring exceptional purity throughout.Cooling:Cooling the Molten Alumina: The delicate art of cooling commences as molten alumina is expertly poured into molds or carefully layered on a cooling floor. This controlled cooling is pivotal in achieving the precise crystal structure and size desired.Formation of Ingots: The cooling phase facilitates the solidification of the material into magnificent ingots or blocks, epitomizing the refined elegance of fused alumina.Crushing and Grinding:Primary Crushing: These solidified ingots are subjected to an initial crushing by powerful jaw crushers or similar machinery, setting the stage for further refinement.Secondary Crushing and Grinding: This phase involves meticulous grinding and crushing through cone crushers, roll crushers, and ball mills, ensuring the material achieves the desired particle size.Magnetic Separation:Removing Metallic Impurities: The finely ground material is processed through magnetic separators, which excel in removing iron particles and other metallic impurities, guaranteeing superior purity.Sieving and Classification:Particle Size Distribution: The refined alumina is meticulously sieved into diverse grades based on particle size, employing vibrating screens and air classifiers for extraordinary precision and accuracy.Quality Control: Every batch undergoes stringent testing for chemical composition, particle size distribution, and other pivotal quality parameters to ensure adherence to industry standards and deliver exceptional quality.ApplicationBrown fused alumina is renowned across numerous industrial sectors for its extraordinary hardness, superior toughness, and impressive high melting point, making it an indispensable, unparalleled component in various applications:Abrasives: An essential element in the production of grinding wheels, sandpaper, blasting media, and a broad spectrum of premium abrasive products, offering unmatched performance.Refractories: Integral to the fabrication of refractory bricks, castables, and other durable materials engineered to endure extreme heat and withstand temperature challenges effectively.Surface Preparation: The ultimate choice for precise cleaning, deburring, and preparing surfaces in metalworking, automotive, and other precision-focused industries, ensuring impeccable results.Ceramics: A crucial component in crafting ceramic products that demand exceptional durability and resistance to thermal shock, ensuring longevity and outstanding performance.Detailed Photos Product ParametersGRAIN SIZES AVAILABLE (F) Discover the unparalleled versatility of our High Purity Brown Fused Alumina Blocks, expertly crafted to meet the rigorous demands of industrial grinding applications.
