description A new flux, JDN-I, including rare earth compounds, for purification of the scraps of 99.99% aluminum foil was introduced. The experimental results indicate that its function of degassing and deoxidizing is excellent. The hydrogen content of the scrap aluminum foil melt purified by JDN-I flux decreases greatly from 4.5 mL/kg to 1.2mL/kg at 720 ℃. The tensile strength of the samples refined with JDN-I flux increases by 19.2% and the elongation increases by 38.3% in comparison with those without flux. The purification mechanism of JDN-I was discussed and a theory of covering, protecting & atomic purification was also put forward.
