加入一定量的第三元素Si，常可令在液态铝合金中的铁，由不饱和状态转变为过饱和状态，以含铁化合物T2初晶形态析出。利用固-液两相的密度差，进行控制在585 ℃的等温精炼。使含铁化合物发生重力分离，将铁去除。试验中获得的“超净化”现象，可令铸造铝合金中的铁的质量分数由2%下降至0.5%。

Adding cerbain quantity of third element Si to molten a luminum makes Fe transfer from unsaturated to supersaturated states with Fe cont aining primary phase T2 prepcipitation.Based on the density difference betwee n solid-liquid phase and isothermal refinement at 585 ℃, Fe was removed due to the Fe-containing phase to gravity deposit. The phenomenon of "super purification" obtained dur ing the experiment could make Fe in cast Al alloy decrease from 2% to 0.5%.
