摘要:
本发明公开了一种有色金属的稀土精炼方法,属于有色金属领域。其包括以下步骤:(1)铝液精炼的准备;(2)稀土的加入;(3)铝液的静置;(4)精炼后处理。本发明解决了现有铝液在精炼的过程中,因铝液中的氢不易除去,而使铝液容易出现针孔的问题,具有方法简单,成本低,加工容易的优点。
摘要(英):
The invention discloses a rare earth refining method for a nonferrous metal, and belongs to the field of nonferrous metals. The rare earth refining method comprises the following steps: (1) preparing for molten aluminum refinement; (2) adding the rare earth; (3) standing the molten aluminum; (4) treating after the refinement. The rare earth refining method disclosed by the invention solves the problem that in the existing molten aluminum refining process, pinholes are easily generated in the molten aluminum as hydrogen in the molten aluminum is difficult to remove; the refining method provided by the invention has the advantages of being simple, low in cost and easy to process.
