Universal Grain Refiner is a white powder or granular flux. After being dried by a variety of inorganic salts, it is mixed and formulated in a certain proportion.
Aluminum and aluminum alloys are rich in natural resources and have the characteristics of light weight, high strength, easy processing, corrosion resistance and beautiful appearance.
Therefore, its power is increasingly shown in industry, national defense, science and technology and daily life.From the perspective of application, it is second only to steel.
With the massive increase in the demand and production of aluminum materials, more and more attention is paid to the quality of aluminum and aluminum alloys.
Molten Aluminum Refining uses the flux added to the aluminum liquid to form a large number of fine droplets, so that the oxides in the aluminum liquid are wetted, absorbed and dissolved by these droplets, forming new droplets and rising to the surface. After cooling, the scum is formed and removed.
The flux used for purification is composed of salt with low melting point, low density, low surface tension, high activity, and strong adsorption capacity for oxidized slag.
Universal Grain Refiner function
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 also has the function of a slag cleaning agent.
Features
Some components in the refining agent are easily decomposed at high temperature, and the generated gas is easy to react with hydrogen, and has a strong adsorption force with slag inclusions, and quickly escapes from the melt. Other components also have the function of slag cleaning agent.
Scope of use
It 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.
How to use? Sprinkle the refining agent on the liquid surface, quickly press it into the molten aluminum, stir it and let it stand still to remove the slag; for example, with the help of a sprayer, spray the refining agent into the molten aluminum with inert gas for better results.
