Refining Flux is a key chemical additive used in aluminum melt processing to remove hydrogen, oxides, and other impurities, ensuring high-quality aluminum casting and rolling products. It is a fine white to slightly gray powder, composed mainly of chloride and fluoride salts, along with other functional compounds.
After heating and screening, the flux particles are uniform in size, allowing them to evenly disperse into the lower layers of the aluminum melt under the action of carrier gases such as nitrogen (N₂) or argon (Ar). During operation, countless fine bubbles form in the molten aluminum, which effectively capture hydrogen and other harmful gases. Simultaneously, flux components adsorb or dissolve oxides and suspended inclusions, which attach to rising bubbles and are removed at the surface.
Key Features
- Uniform particle size for efficient dispersion
- Effective hydrogen removal and dross separation
- Physical purification with low burning loss
- Non-sticky and loose aluminum dross
- Compatible with different aluminum alloy melts
Product Advantages
Effective Degassing and Deslagging
Refining flux produces fine bubbles that interact fully with the aluminum melt, removing hydrogen and bringing oxides and impurities to the surface for easy removal.
Low Material Loss & Reusability
The flux has low burning loss, forming loose, non-sticky dross, reducing material waste and improving operational efficiency.
Improved Metal Quality
By removing dissolved gases and inclusions, refining flux enhances aluminum melt cleanliness and downstream casting quality.
