The refining agent is generally introduced into the aluminum alloy melt with inert gas as a carrier for degassing and impurity removal. Refining agent is also called Aluminum Flux, Aluminum Casting Flux, Flux Aluminium, Aluminium Degassing Tablets, Flux For Aluminum Melting, Flux For Melting Aluminum Cans, Aluminium Casting Flux, Aluminum Casting Foundry Flux, Aluminum Degassing Flux, Aluminum Flux Powder.
Aluminum alloy will inevitably absorb and carry gas and produce inclusions during the smelting process, which will cause a series of defects such as porosity, shrinkage, shrinkage, cracks and leakage of the casting, which will reduce the purity of the aluminum alloy and affect the quality. Therefore, the aluminum alloy smelting process must be refined and purified to eliminate these gases and inclusions and improve the quality of the aluminum alloy. Adding a refining flux to the aluminum alloy for refining and purification is a common measure.
The refining flux is a white powder or granular flux. It is prepared by mixing a variety of inorganic salts after drying treatment in a certain proportion. The refining agent is mainly used to remove the hydrogen and floating oxidized slag in the aluminum liquid, so that the aluminum liquid is more pure, and it has the effect of a slag cleaning agent. Part of the components in the degassing refining flux is easily decomposed at high temperatures, and the generated gas is prone to hydrogen reaction, has a strong adsorption force with slag inclusions, and quickly escapes from the melt. Other components have the function of slag cleaning agent.
The refining flux is suitable for common grades of aluminum alloy (alloys with high magnesium content and aluminum-magnesium alloys cannot be used), and when smelting pure aluminum, degassing refining and slag removal.
Refining Agent Usage: Sprinkle the refining agent on the liquid surface, quickly press it into the molten aluminum, fully stir and let it stand for slag removal. For example, with the help of a sprayer, spray the Aluminum Casting Flux into the molten aluminum with inert gas for better results.
The potassium-free refining agent provided by AdTech has good slag-making performance, strong degassing and impurity removal capabilities, and low cost. The aluminum ash produced after refining aluminum and aluminum alloys with the Aluminium Granulated Flux can be recycled into the tank.
The aluminum alloy smelting refining flux increases the ability to remove hydrogen, reducing the hydrogen content to the level of 0.12ml/g Al, and the removal effect is obvious, and the refining production process after adding the Aluminum Flux is simple, which improves the utilization rate of the refining flux.
