Product Description Product DescriptionBrown Fused Alumina, renowned in the industry as Brown Aluminum Oxide, is a top-tier synthetic mineral celebrated for its unparalleled hardness and remarkable wear resistance. This exquisite material is meticulously engineered through an advanced process that merges bauxite, iron filings, and anthracite in a high-temperature electric arc furnace. Following this fusion, it undergoes a meticulous cooling, crushing, and screening sequence to ensure the pinnacle of quality standards. The superior physical and chemical properties of this product make it essential for a multitude of industrial applications, delivering exceptional performance and enduring 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 captivating journey through the intricate creation of brown fused alumina (BFA), a masterpiece of precisely orchestrated stages. From the initial raw material preparation, through fusion and cooling, to the final crushing and meticulous classification, each step unveils the artistry behind this exceptional process.Raw Material Preparation:Bauxite: This vital cornerstone of our premium production is meticulously chosen for its rich alumina (Al2O3) content. Our carefully selected bauxite guarantees purity and superior quality, laying the foundation for outstanding results.Iron filings or scrap iron: Skillfully integrated into the mix, these materials enhance the reduction process during fusion, significantly boosting efficiency and quality.Anthracite coal: Serving as an essential component in the fusion process, anthracite coal acts as a powerful reducing agent, playing a crucial role in achieving the desired transformation.Fusion:Electric Arc Furnace (EAF): Our expertly blended mixture is introduced into the Electric Arc Furnace, where temperatures soar to an astonishing 2000-2200°C (3632-3992°F). Under the influence of potent electric arcs from carbon electrodes, the transformation begins.Reduction and Fusion: Within this intense high-temperature environment, the bauxite's alumina melts and reacts with the carbon from anthracite, producing molten alumina. Impurities such as iron are effectively reduced and separated, ensuring exceptional purity.Cooling:Cooling the Molten Alumina: The process continues as molten alumina is expertly poured into molds or spread on a cooling floor. This controlled cooling process is essential for achieving the desired crystal structure and size.Formation of Ingots: During the cooling phase, the material solidifies into magnificent ingots or blocks, showcasing the luxurious form of fused alumina.Crushing and Grinding:Primary Crushing: These cooled ingots undergo an initial breakdown by robust jaw crushers or similar machinery, preparing them for further refinement.Secondary Crushing and Grinding: This phase involves meticulous crushing and grinding using cone crushers, roll crushers, and ball mills, ensuring the material achieves the optimal particle size.Magnetic Separation:Removing Metallic Impurities: The finely ground material is passed through magnetic separators, which excel at removing iron particles and other metallic impurities, ensuring immaculate purity.Sieving and Classification:Particle Size Distribution: The refined alumina is expertly sieved into various grades based on particle size, utilizing vibrating screens and air classifiers for exceptional precision and accuracy.Quality Control: Each batch undergoes rigorous testing for chemical composition, particle size distribution, and other critical quality metrics to ensure full compliance with industry standards and deliver unrivaled quality.ApplicationBrown fused alumina is renowned across numerous industrial sectors for its extraordinary hardness, outstanding toughness, and exceptional high melting point, making it an unparalleled necessity:Abrasives: This powerhouse material is essential in crafting high-performance grinding wheels, superior sandpaper, blasting media, and a vast array of other premium abrasive products, ensuring precision and excellence in every application.Refractories: At the heart of producing refractory bricks, castables, and other robust materials, brown fused alumina is engineered to withstand extreme heat, embodying reliability and resilience in high-temperature environments.Surface Preparation: The ultimate choice for cleaning, deburring, and surface preparation, especially in metalworking, automotive, and precision industries, where attention to detail is paramount. It ensures surfaces are impeccably prepared for the next stage.Ceramics: A critical ingredient in ceramic products, brown fused alumina enhances durability and thermal shock resistance, granting these items exceptional longevity and performance, meeting the industry's rigorous demands.Detailed Photos Product ParametersGRAIN SIZES AVAILABLE (F) Experience the exceptional versatility of our Brown Fused Alumina Abrasive Blocks, designed to deliver superior performance across an expansive spectrum of industrial uses.
