Drossing-Off Flux
General Description And Function of Drossing-Off Flux Drossing-off flux is used to absorb oxides and non-metallic material, cleansing the metal and forming a good metal-free dross which can easily be removed. Drossing-off fluxes agglomerate the oxides allowing easy removal from the surface of the melt. They are used to remove the dross with the minimum metal loss Advantages of Drossing-Off Flux 1. Being exothermic fluxes, it can ensure that liquid aluminum trapped in the dross layer is returned to the melt. Produce dry powdery dross. 2. Provide further decrease of the flux melting point and improve its cleaning ability. Due to the high wetting capacity of fluoride compounds: it has a good effect of contributes to oxide – metal separation. 3. It helps recover metal from this slag layer , improving the yield of the process.
