The manufacturing journey of our exquisite brown fused alumina (BFA) is a meticulous sequence of steps, encompassing the preparation of raw materials, fusion, cooling, crushing, and classification. Delight in the intricate stages of this sophisticated process:
Raw Material Preparation:
Bauxite: This is the cornerstone of our production, carefully chosen for its high alumina (Al2O3) content and supreme purity, ensuring excellence in every grain.
Iron filings or scrap iron: Integrated into the mix to facilitate the reduction process during fusion, enhancing the purity of the final product.
Anthracite coal: Utilized as an essential reducing agent, crucial for achieving the premium quality of our alumina.
Fusion:
Electric Arc Furnace (EAF): This is where the magic happens. The meticulously prepared mix is introduced into an electric arc furnace, achieving blistering temperatures of 2000-2200°C (3632-3992°F) via electric arcs from carbon electrodes.
Reduction and Fusion: In this intense heat, the alumina melts and reacts with carbon to form a molten masterpiece, while iron and impurities are deftly reduced and separated.
Cooling:
Cooling the Molten Alumina: The molten marvel is carefully poured into molds or onto cooling floors, undergoing a controlled cooling process pivotal for attaining the optimal crystal structure and size.
Formation of Ingots: As it cools, it solidifies into formidable ingots or blocks, setting the stage for the next transformation.
Crushing and Grinding:
Primary Crushing: The cooled giants are first tackled by jaw crushers or robust machinery, breaking them into manageable pieces.
Secondary Crushing and Grinding: These chunks are further reduced through cone crushers, roll crushers, and ball mills into finer particles, culminating in the perfect size.
Magnetic Separation:
Removing Metallic Impurities: The ground particles make their way through magnetic separators, ensuring any lingering iron and metallic impurities are expertly removed.
Sieving and Classification:
Particle Size Distribution: The refined alumina undergoes sieving into varied grades based on particle size, utilizing vibrating screens and air classifiers for precision.
Quality Control: Every batch undergoes rigorous testing for chemical composition, particle size distribution, and quality parameters, ensuring it meets and exceeds industry standards.
Brown fused alumina is a versatile star in the realm of industrial applications, cherished for its remarkable hardness, unparalleled toughness, and impressive high melting point:
Abrasives: It stands out as a premium choice in the creation of grinding wheels, enhancing the effectiveness of sandpaper, and adding precision to blasting media, along with other top-notch abrasive products.
Refractories: A crucial component in crafting refractory bricks and castables, ensuring that materials can bravely endure extreme temperatures with unwavering strength.
Surface Preparation: An indispensable ally in industries such as metalworking and automotive, where it excels in cleaning, deburring, and impeccably preparing surfaces for optimal performance.
Ceramics: An essential ingredient in crafting ceramic products, delivering unmatched high durability and resistance to thermal shock, ensuring longevity and reliability.
