The high-efficiency aluminum melting 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 the metal solvent also has the effect of removing slag. The principle is that some members of the molten aluminum refining agent are easy to decompose at high temperature, the generated gas reacts with hydrogen, and can also strongly adsorb slag, which can play a certain role in slag removal.
Aluminum melting refining agent can be used for various aluminum alloys. If alloys with relatively high magnesium content and aluminum-magnesium alloys cannot be used unexpectedly, they can be used for pure aluminum smelting for refining and slag removal. When using, 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 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 aluminum melting refining agent from blocking the nozzle. If you find that the molten 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 molten aluminum refining agent to the surface of the molten aluminum, so that the surface of the molten aluminum can be evenly covered, and the molten aluminum is protected from air oxidation. The added amount needs to be added according to the proportion.
