Refining Agent/ Flux

Refining Agent is a functional chemical additive widely used in the metal smelting industry, mainly designed to remove impurities (such as gas, slag, and inclusions) from molten metals and optimize the physical and chemical properties of the metal matrix. It is commonly used in the processing of non-ferrous metals like aluminum, copper, and magnesium, as well as in the smelting of certain ferrous metals.

Working Mechanism

1. Melting and Dispersion: When added to molten metal, the refining agent quickly melts and disperses uniformly, forming a reaction interface with the molten metal.

2. Impurity Reaction: It reacts chemically with dissolved gases (e.g., hydrogen) and solid inclusions (e.g., oxides, carbides) in the molten metal to form low-density, easy-to-separate compounds.

3. Separation and Removal: The reaction products (such as slag or gas bubbles) float to the surface of the molten metal under the action of buoyancy, and are then removed by slag skimming or vacuuming, achieving purification.

Applications

- Aluminum Industry: Used in the smelting of primary aluminum and recycled aluminum to remove hydrogen and oxide inclusions, ensuring the quality of aluminum profiles, plates, and castings.
