Granule Refining Flux

Granule refining flux is a highly efficient molten refining agent specifically designed for the aluminum alloy smelting process. It is in uniform granular form, facilitating feeding and dispersion. The recommended addition amount is 0.08%-0.15% of the total melt volume. It is effective at refining temperatures of 700-720℃ and above. This refining agent's core characteristic is its environmental friendliness and smokeless operation; it does not produce irritating fumes during the smelting process, significantly improving the workshop working environment. Each bag is packaged in a standard 5 kg form, ensuring precise measurement and convenient on-demand use. Its excellent overall performance effectively improves the purity of molten aluminum, making it an ideal auxiliary material in the aluminum alloy smelting process.

Main Advantages: Environmentally friendly and smokeless, green smelting: This product is effective at temperatures of 700-720℃." The reaction is stable at the above operating temperatures, releasing almost no visible smoke or harmful odors, fully meeting the requirements of modern foundry enterprises for clean production and occupational health and safety, reducing the burden of flue gas treatment at the source.

Outstanding refining effect: Highly efficient refining can be achieved at a low addition level of 0.08%-0.15%, quickly adsorbing and carrying oxide inclusions, slag, and other impurities in the molten aluminum to the surface, forming easily removable dry slag, significantly improving the purity of the molten aluminum, thereby enhancing the mechanical properties and surface quality of aluminum alloy castings.

Particle form, convenient operation: The product is in regular granular form, with good flowability and is not prone to moisture absorption and clumping. It can be evenly sprinkled manually or mechanically during feeding, with rapid dispersion and good contact with the molten aluminum. With a large contact area, it melts rapidly and participates in the reaction, avoiding the drawbacks of powdered refining agents, such as easy dispersion and significant losses.

Wide applicable temperature range: Recommended operating temperature is 700-720℃ and above, covering the temperature range of most aluminum alloy melting, holding, and settling processes. Even at slightly higher melting temperatures, this product maintains stable performance without producing side reactions.

Economical and practical: Pre-packaged in 5 kg bags, facilitating inventory management and cost accounting. The combination of low dosage and high efficiency helps users obtain clean aluminum liquid at a lower cost per ton of aluminum, offering high overall cost-effectiveness.

Product Applications: Granule refining flux is widely used in various aluminum alloy melting processes, especially suitable for casting processes requiring high aluminum liquid cleanliness. Purification treatment of aluminum alloys, wrought aluminum alloys, and recycled aluminum. Specifically, this includes, but is not limited to:

Refining and removing impurities from die-cast aluminum alloys to reduce porosity and shrinkage defects in castings;

Purification of molten aluminum for gravity casting and low-pressure casting to improve casting density and elongation;

Pre-treatment of melt during aluminum rod and profile production to reduce the risk of slag inclusions;

Slag separation during recycled aluminum smelting to improve metal separation efficiency and reduce aluminum loss.

Whether in a centralized smelting furnace, crucible furnace, or reverberatory furnace, adding this refining agent in the temperature range above 700-720℃ can produce clean molten aluminum and dry, easily removable slag, suitable for refining processes in small and medium-sized aluminum processing enterprises and large aluminum plants.
