Aluminum refining agent is white powdery and granular. It is made by mixing a variety of inorganic salt drying treatments according to a certain proportion. It plays an important role in the process of smelting aluminum. What is the role of the specific aluminum refining agent? Let me explain in detail below.

The aluminum refining agent is mainly used to clear the hydrogen inside the molten aluminum and the floating oxidized slag, which can make the aluminum liquid more pure and also has the effect of removing slag. Some members of the aluminum refining agent are easy to separate under high temperature, the generated gas can react with hydrogen, and can absorb the slag strongly, and quickly escape from the melt, playing a certain role in slag removal.

Aluminum refining agent can be used for a variety of aluminum alloys, if alloys with relatively high magnesium content and aluminum-magnesium alloys cannot be used. It can be used for pure aluminum smelting to play the role of refining and slag removal. When in use, you only need to sprinkle the refining agent on the surface, and then the refining agent will quickly dissolve in the aluminum liquid, and then fully stir. If you use a sprayer, the effect of spraying the refining agent with inert gas will be better, for example, nitrogen and argon can be selected.

Pay special attention when spraying. At the beginning, the air must be turned on and then the powder will be supplied. At the end, the powder must be cut off before the air is stopped. This is to prevent the aluminum refining agent from blocking the nozzle. If you find that the aluminum refining agent is damp or agglomerated, you can continue to use it after opening the package and drying it in the sun.

It is necessary to add enough aluminum refining agent to the surface of the aluminum liquid, so that the surface of the aluminum liquid can be evenly covered and protect the aluminum liquid from air oxidation. The added amount needs to be added according to the proportion.
