How is Pink Fused Alumina Produced?
Pink Fused Alumina is produced through a specific fusion process in an electric arc furnace. Here’s an overview of the production steps:
Raw Material Selection:
The primary raw material for Pink Fused Alumina is aluminum oxide (Al2O3). A precise amount of chromium oxide (Cr2O3) is added to the aluminum oxide. The presence of chromium oxide differentiates Pink Fused Alumina from other types of fused alumina, giving it its characteristic pink color.
Melting:
The aluminum oxide and chromium oxide mixture is melted in an electric arc furnace at temperatures exceeding 2000°C. This high-temperature process ensures the complete fusion of the materials.
Cooling and Solidification:
After achieving the desired melt composition and homogeneity, the molten material is cooled and allowed to solidify. This cooling process is controlled to promote the formation of the desired crystal structures.
Crushing and Sizing:
The solidified material is then crushed into smaller pieces and processed into grains of specific sizes, suitable for various abrasive applications. This step involves a series of crushing, milling, and screening operations to achieve the desired grain sizes.
Quality Control:
Stringent quality control measures are in place throughout the production process to ensure the final product meets specific standards for chemical composition, grain size, and purity. Samples are tested for physical and chemical properties to ensure they meet industry standards and application requirements.
The addition of chromium oxide not only imparts the pink color but also enhances the toughness and durability of the alumina, making Pink Fused Alumina suitable for precision grinding applications where a balance between cutting efficiency and abrasive life is required.
