The aluminium refining flux is white powder and granular. It is mixed according to a certain proportion after the drying of various inorganic salts. It plays an important role in the process of smelting aluminium. What is the role of the specific aluminium refining agent?
Aluminium refining flux is mainly used to remove the hydrogen and floating oxidized slag inside the aluminium liquid, which can make the aluminium liquid purer and also has the effect of removing slag. Aluminium refining agent is easy to decompose at high temperature, the generated gas can react with hydrogen, and can strongly adsorb slag, and quickly escape from the melt, playing a certain role in slag removal.
Aluminium refining flux can be used for all kinds of aluminium alloys, can be used for pure aluminium smelting, and play the role of refining and slag removal. When using it, you only need to sprinkle the refining agent on the surface, and then the refining agent will quickly dissolve in the aluminium liquid, and then fully stir. If you use a jet machine, the effect of using inert gas to spray the refining agent 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 aluminium refining agent from blocking the nozzle. If you find that the aluminium 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 aluminium refining agent to the surface of the aluminium liquid, so that the surface of the aluminium liquid can be evenly covered and protect the aluminium liquid from air oxidation. The added amount needs to be added according to the proportion.
