Aluminum Alloy Refining Fluxes

Aluminum Alloy Refining Fluxes

The main purpose of aluminum alloy refining fluxes is to agglomerate nonmetallic inclusions and break apart and pile up oxide particles. It begins slowly sink when added into the melt with dissolving and absorbing the oxides and gases. It plays an important role in improving the quality of aluminum and aluminum alloy castings.

Our country is a country with relatively developed industrialization. In many industrial production processes, especially metal smelting, various refining agents are added to improve the performance advantages of products. Regardless of the pharmaceutical industry or the metal industry, refining agents are one of the common fluxes products, mainly white powder or granules, which are prepared by a variety of inorganic salt treatments in a certain proportion. So, what do you know about the role of aluminum alloy refining fluxes and how to use it?

Adding an appropriate amount of refining agent when smelting aluminum products can effectively remove the hydrogen contained in the aluminum liquid and the floating oxidized slag. The main reason is that the refining agent is easy to decompose at high temperature, especially the produced gas is prone to chemical reactions, and the strong adsorption capacity of slag inclusion can allow hydrogen to escape from the melt, so it can achieve slag removal effect. It is a good choice for companies with high requirements for smelting pure aluminum, and it has been unanimously praised and recognized by customers.

Degassing with Flux

In fact, the use of refining agents is relatively simple, you can learn more about their use before using them. Especially, evenly sprinkle it on the surface of the liquid, quickly press it into the molten aluminum, and perform slag removal after fully mixing and standing still. Adding flux to the melt surface, stirring the flux with a lance to ensure the maximum contact between the flux and aluminum metal. It will be better to use inert gas to spray it. The dosage is about 0.3% of the weight of the aluminum liquid. If the purity of the aluminum liquid is relatively high, please add more refining agents.
