Drossing Flux

Change the composition and properties of the slag, so that the scum is loose and easy to clean and scrape out.
Remove the oxide scale and impurities in the molten aluminum, clean the slag thoroughly, and clean the molten aluminum to ensure the quality of the castings.

Technical introduction

When aluminum or aluminum alloy is melted or refined, a lot of scum is produced, and when mixed with aluminum, more scum is produced. The scum is easy to stick to form a block, absorb a large amount of molten aluminum, and it is difficult to operate when removing the slag, and a large amount of molten aluminum is taken away, resulting in losses. With the use of slag, these problems are solved.

The slag is loose, which can significantly reduce the loss of molten aluminum, which can reduce the loss of molten aluminum by 0.3 to 0.5 kg per ton.

Instructions

After the refining flux is sprayed into the aluminum melt, there will be oxidation inclusions floating and gas precipitation, forming a viscous wet slag on the surface of the aluminum liquid. At this time, add the drossing flux to the surface of the molten aluminum and stir gently, and the viscosity of the slag will decrease immediately.
