日本工业技术院名古屋工业技术研究所的非平衡工艺研究院,开发了从再生铝合金中除去铁的脱铁技术。为提高再生铝合金的再利用率,必须尽量减少其中的杂质。但是,其中最易混入铝合金中,损害产品机械性质的材料是铁。用工业方法除去已在熔液中熔化的铁质是一大难题。名古屋工艺研究所,在铝合金熔液中生成铝一铁系金属化合物,使容器旋转,利用离心力,将铁质多的部分集中到外周部从而分离出来。实验结果表明,从含铁2％的铝合金中,可除去85％左右的铁,可制成高质量的含铁0.3％以下的铝合金。
Japan Institute of Industrial Technology Nagoya Institute of Technology Institute of non-equilibrium process, developed from the removal of iron from the regeneration of the iron off the iron technology. In order to improve the reutilization rate of recycled aluminum alloy, the impurities in it must be minimized. However, the most easily mixed into the aluminum alloy, the material that impairs the mechanical properties of the product is iron. Industrial methods to remove iron that has been melted in the melt are a big problem. Nagoya Process Research Institute produces aluminum-iron-based metal compounds in the aluminum alloy melt and rotates the container. Centrifugal force concentrates the iron-rich portion to the periphery to separate it. The experimental results show that about 85% of the iron can be removed from the aluminum alloy containing 2% of iron, and high quality aluminum alloy containing less than 0.3% of iron can be made.
