How to Use Aluminum Flux
Pay attention to the following issues when using flux refining
1) Different alloys should use different fluxes
We provide refining flux, slagging flux, oxide removal flux, and covering flux. AdTech refining flux is a kind of white with slightly gray fine particles. The Main ingredients are chloride with other compounds. Deslagging flux is used for deslagging for roll casting and molten Aluminum alloy, especially for A356.2 alloy and wheel hub. Oxide Removal Flux is used for removing hard slags from the furnace wall and bottom. Covering Flux is used for inner furnace covering to prevent molten aluminum oxidation, lower oxidation, and burning loss.
2) Perform thorough pre-refining preparations
Before refining, thoroughly dry the flux to remove moisture. This prevents explosions when the flux is added to the molten aluminum and improves refining efficiency. The flux particle size should be appropriate, generally between 50 and 80 mm. Before refining, preheat the refining basket, brush the basket, and activate the fume exhaust. Turn off the furnace.
3) Perform refining operations strictly according to regulations
The refining temperature should be controlled within the upper limit of the pouring temperature to improve refining efficiency. Sufficient flux should be used. For products requiring higher internal purity, the flux dosage can be increased appropriately, generally to 6-8 kg/ton of metal; for general products, the flux dosage is 5-6 kg/ton of metal. During refining, place the refining basket at the bottom of the furnace and move it slowly and evenly to eliminate dead spots. Avoid refining in fixed spots. After the reaction is complete, remove the refining basket. After refining is complete, immediately remove the slag, apply a covering agent, and allow the basket to rest. The resting time varies depending on the product. Important products should be left standing for no less than 30 minutes; general products should be left standing for no less than 15 minutes.
