Aluminum alloy casting flux can degass and remove impurities, make aluminum alloy solution purer and improve its mechanical properties.
The amount of Aluminum Alloy Casting Flux added to aluminum alloy casting should be determined according to the weight of liquid aluminum, because too much or too little will affect the performance of aluminum alloy, so it must be calculated before adding.
When operating the refining agent, the operator should control the refining flow freely through the barometer and powder feeder to control the rolling degree of molten aluminum, so as to reduce the secondary pollution. Nitrogen and argon are usually used as carriers to form a large number of dispersed bubbles in aluminum alloy solution. During the floating process of bubbles, the molten aluminum will completely contact and quickly remove the gas and inclusions in the liquid aluminum.
At the same time, some substances contained in the aluminum casting flux can strongly adsorb the oxides and suspended solids in the molten melt, and adhere to the bubbles. As the bubbles rise, they are brought to the surface of liquid aluminum, so as to achieve the purpose of refining.
Aluminum slag is an inevitable part of the melting aluminum and casting process. Although relevant measures have been taken, a certain proportion of aluminum has been removed. Therefore, smelters need to deal with aluminum slag effectively. The simplest and most economical method is to grind the aluminum slag repeatedly with a grinder, and then screen to recover part of aluminum effectively.
Special attention should be paid to the use of aluminum alloy casting flux. Let air in before adding powder. Finally, stop the powder before stopping the gas. This is to prevent the nozzle from being blocked by aluminum concentrate. If water or nodules are found in the liquid aluminum refining agent. If it is square, you can open the package, dry it in the sun and continue to use it. Sufficient liquid aluminum preparation must be added to the surface of the liquid aluminum to make the surface of the liquid aluminum evenly covered and protect the liquid aluminum from being oxidized by air. The amount of liquid aluminum preparation should be added in proportion.
