Slagging Flux is a chemical, white powder, mainly used for aluminum and aluminum alloys other than high magnesium aluminum alloys.
Slagging Flux can change the interfacial tension between the aluminum melt and the slag body, reduce the bonding force between the melt and the slag body, effectively separate the metal from the slag, and improve the metal utilization rate.
After the Slagging Flux enters the aluminum melt, a large number of bubbles escape and play a certain role in stirring the melt.
These bubbles fully pull the slag of the aluminum melt to the surface of the metal liquid, which is conducive to the complete removal of the slag and the cleanness of the melt.

Why Use It?
After the melting of aluminum and aluminum alloys, especially after using Non-Sodium Granulated Flux , there is a thin layer of scum on the surface of the aluminum liquid. These slags contain more metal aluminum. The function of slagging is to change the wettability of the slag and aluminum liquid. Increase the surface tension at the interface of the slag and aluminum, making it difficult for the aluminum to wet the slag Content, reduce the amount of aluminum liquid brought out during slag stripping, reduce the loss of aluminum, and increase economic benefits.
Alloy: Except for high-magnesium aluminum alloys, other aluminum and aluminum alloys
Good heat generation, can separate aluminum beads from the slag, and can partially decompose alumina to form light, loose powder scum, reduce slag adhesion to the lining.
Add 0.1% -0.2% of aluminum alloy melt
After refining, the aluminum slag powder is evenly spread on the surface of the slag, and the Slagging Flux is stirred in time.
After the slag is crushed, the slag powder is pulled out.
If the aluminum slagging agent is used as a covering agent, it is best to sprinkle it into the flux in three times.
The first time it is added when the charge starts to melt, the second time it is added after all melting, and the third time it mainly plays the role of separating the slag aluminum and should be refined.
Covering agent, slagging agent, slag cleaning agent, refining agent used in aluminum alloy melting
1. When the temperature of the aluminum alloy reaches about 660-720 degrees, add the refining agent. Press the tool to the bottom until no bubbling occurs. It is mainly used to remove hydrogen from the aluminum liquid. Refining agent: zinc chloride.
2. Add slagging agent after refining, remove the slag after fully stirring with tools, mainly used to remove impurities in the aluminum liquid, slagging agent is mainly used for lead alloy smelting.
3. After the slag is cleaned, spread covering agents such as expanded perlite and expanded graphite on the surface to prevent the hydrogen in the air from entering the aluminum liquid and keeping it warm.
4.After the melting of aluminum and aluminum alloys, the furnace cleaning agent cleans the furnace wall.
