Aluminium Grain Refiner is used for degassing and slagging of molten metal during aluminum alloy casting.
It adopts unique technology to improve the effect of traditional degassing and slag removal in the molten metal. It is used in the casting and rolling process of many series of aluminum alloy products: micron-level aluminum foil wool, PS plate base for printing, can making material, elasticity Purification of degassing and slag removal of liquid metal in the process of casting aluminum alloy raw materials such as packaging materials, rail transit, aerospace products, cable wires, etc.

Aluminium Grain Refiner main advantages
1. Since this product does not contain sodium, it avoids or reduces the occurrence of white spots on the surface of aluminum and aluminum alloys.
2. Good heat generation, the aluminum in the slag is separated, and the alumina in the slag is decomposed, so that the aluminum slag is dry and loose, which is very easy to remove.
3.After the treatment, the purity of the aluminum liquid is greatly improved, the performance of the alloy is improved, and the aluminum consumption is reduced.
4. Reduce the adhesion of slag to the furnace wall and bottom, avoid the damage of the furnace body, prolong the service life of the aluminum body and reduce the number of furnace cleaning.

How to use Aluminium Grain Refiner
1. The amount of this refining agent is about 0.3% (the amount depends on the situation);
2. When using, pour this product into a special container, connect it with argon gas or dry nitrogen gas, blow it into the aluminum liquid by pressure, and stir it repeatedly and evenly.
Set a period of time and then cast;
3. Sprinkle the cast aluminum refining agent on the liquid surface, quickly press it into the aluminum liquid, stir it fully, and let it stand, slag slag; if using a spray machine, use an inert gas to spray the refining agent into the aluminum liquid.
Better
4. Press the cast aluminum refining agent into the bottom of the aluminum liquid. At this time, due to the release of a lot of heat, the aluminum liquid quickly heats up and becomes red. The Granulated Flux should be fully connected to the aluminum liquid.
Touch and remove the slag after it is dry and powdery.

Scope of application: Deslagging and degassing of aluminum and aluminum alloy liquids.
Product performance: The appearance is white powder, the water content is less than 0.5%. This refining agent is used for powder refining. Since the powder is sprayed with inert gas, it has the effect of removing slag and degassing. So the amount of refining agent is relatively small , Deslagging and degassing effect is stronger.

Note: should be stored in a dry place. Prevent moisture and pressure

Aluminium Grain Refiner evenly enters the lower layer of the aluminum liquid through the powder sprayed through the refining agent tank under the action of the carrier gas (N or Ar), and forms numerous small bubbles in the aluminum liquid through physical and chemical changes to fully contact the aluminum liquid and separate the aluminum liquid [H] and other harmful gases.
At the same time, some substances contained in the refining agent can strongly adsorb and melt the oxides and suspended matters in the melt and attach to the bubbles together, and they will be brought to the surface of the aluminum liquid as the bubbles rise, so as to achieve the purpose of degassing and slag removal.

The refining agent is mainly used to remove hydrogen and floating oxidized slag inside the aluminum liquid, so that the aluminum liquid is more pure, and also has the role of a slag cleaning agent.

Some components in the refining agent are easily decomposed at high temperature, the generated gas is easy to react with hydrogen, and has strong adsorption force with the slag, and quickly escapes from the melt. Other components also have the function of slag cleaning agent.
