Essential Raw Material Preparation:
Bauxite Mastery: As the core component, our bauxite boasts a rich alumina (Al2O3) content, meticulously chosen to maintain superior alumina levels and minimize impurities, ensuring premium quality.
Iron Filings or Scrap Iron: These are introduced into the blend to facilitate the reduction process during the remarkable fusion stage.
Anthracite Coal: This serves as a powerful reducing agent, instrumental in the transformation journey.
The Magnificent Fusion Process:
Electric Arc Furnace (EAF): Our expertly prepared mixture enters the electric arc furnace, where temperatures soar to an astounding 2000-2200°C (3632-3992°F), courtesy of electric arcs striking between carbon electrodes.
Reduction and Fusion Magic: Amidst these remarkable temperatures, alumina from bauxite melts and interacts with carbon from anthracite, creating molten alumina while iron and impurities are artfully reduced and separated.
Cooling into Perfection:
Cooling the Molten Alumina: The molten alumina gracefully flows from the furnace into molds or onto cooling floors, where precise temperature control is paramount for achieving the perfect crystal structure and size.
Formation of Ingots: As it cools, the material transforms into substantial ingots or blocks of remarkable fused alumina.
Crushing and Grinding Excellence:
Primary Crushing: Robust jaw crushers and heavy machinery diligently break down the cooled ingots.
Secondary Crushing and Grinding: With precision, the material undergoes further refinement through cone crushers, roll crushers, and ball mills, expertly shaped to the desired particle size.
Magnetic Separation Artistry:
Eliminating Metallic Impurities: The refined material passes through magnetic separators, expertly cleansing it of any residual iron particles and other metallic impurities.
Sieving and Classification Precision:
Advanced Particle Size Distribution: The impeccably crushed and purified alumina is systematically sieved into various grades based on particle size, utilizing state-of-the-art vibrating screens and air classifiers.
Quality Control Assurance: Each batch undergoes rigorous testing for chemical composition, particle size distribution, and other quality parameters, ensuring unwavering adherence to industry standards.
White fused alumina (WFA) is meticulously crafted in an impressive array of sizes, perfectly tailored to satisfy the extensive demands of myriad industrial applications. The particle size of WFA is pivotal, as it can greatly influence performance, necessitating the selection of the ideal size for each unique application. Presented below are the typical sizes of white fused alumina, designed to cater to your precise industrial requirements:
Macro Grit Sizes:
Coarse Grit: Spanning from F8 to F220, conforming to the esteemed FEPA standard.
Commonly utilized sizes include F12, F24, F36, F46, F60, F80, F100, F120, F150, F180, and F220.
Applications: Ideal for heavy-duty grinding, cutting, and surface preparation.
Micro Grit Sizes:
Fine Grit: Extending from F230 to F1200, adhering to the FEPA standard.
Popular sizes typically used include F240, F280, F320, F360, F400, F500, F600, F800, and F1000.
Applications: Perfect for precision grinding, lapping, and polishing.
Powder Form:
Ultra-fine powders with exceptionally small particle sizes, ranging from a few microns to sub-micron levels, offering unparalleled precision.
Applications: Tailored for high-precision polishing, specialty ceramics, coatings, and as a versatile filler in various composite materials.
Choosing the Right Size:
Coarse Grit (F8 - F220): Ideal for applications where high material removal rates and robust surface preparation are critical, such as grinding high carbon steel and engaging in heavy-duty polishing tasks.
Medium to Fine Grit (F230 - F1200): Expertly crafted for situations requiring an exceptional balance between material removal and surface finish quality, ideal for fine grinding, lapping, and precision polishing.
Ultra-Fine Powder: Exceptionally suited for applications demanding an extraordinarily smooth and precise finish, such as the production of advanced ceramics, high-performance coatings, and catalyst carriers.
Selecting the correct size of white fused alumina is essential for achieving optimal performance in your specific application. Whether the need is for coarse grit during heavy-duty grinding or for ultra-fine powders in precision tasks, white fused alumina offers a comprehensive range of sizes to fulfill your requirements. Maximize results by selecting the precise size for your abrasive, polishing, casting, coating, catalytic, ceramic, or refractory application.
