BFA is highly valued for its exceptional hardness, toughness, and thermal stability, making it a versatile choice for numerous industrial applications. It plays a key role in the production of grinding wheels, abrasive blasting media, and refractory materials. Thanks to its excellent resistance to high temperatures and corrosion, BFA is also widely utilized in the foundry and steel industries. Its combination of durability and adaptability ensures consistent demand across sectors that rely on dependable abrasive and refractory solutions.
Brown Fused Alumina Production process
1. Raw Material Preparation:
High-quality bauxite is selected as the primary raw material, often combined with iron filings and anthracite to ensure optimal chemical composition.
2.Smelting:
The raw materials are melted at high temperatures (around 2200–2300°C) in an electric arc furnace. This process removes impurities and forms the fused material.
3.Cooling:
The molten material is cooled and solidified into large, dense blocks under controlled conditions.
4.Crushing and Milling:
The solidified blocks are crushed and milled into smaller sizes to achieve the desired granularity.
5.Magnetic Separation:
Magnetic separation is used to remove any residual metallic impurities from the material.
6.Screening and Grading:
The particles are sieved and graded according to specific size distributions, adhering to standards such as FEPA, JIS, or ANSI.
7.Quality Inspection:
The final products undergo strict quality control checks to ensure consistency in chemical composition, hardness, and particle size.
8.Packaging:
The graded materials are packaged in suitable containers, ready for storage or shipment to customers.
This comprehensive process ensures that brown fused alumina meets the high standards required for abrasive, refractory, and other industrial applications.
