Paper Title:
Effects of Electromagnetic Purification on Properties of Al-RE Rod for Electrical Purpose
  Abstract

An electromagnetic purification system was installed to process molten aluminum in an Al-RE rod continuous casting and hot rolling line. The variation of inclusion concentration in rod samples with and without electromagnetic purification was detected via quantitative metallography. The tensile strength and electrical resistivity of as-rolled rods as well as subsequently cold drawn wires were also tested. Results show that a 61% additional improvement of removal efficiency was achieved by electromagnetic purification other than ceramic foam filtration. The inclusion concentration in the rods has negligible impact on electrical resistivity of samples and the deformation restricts the fluctuation of electrical properties apparently. The UTS of drawn wires with electromagnetic purification improves by 3%-5% as compared with those with filtration only, while the variation of inclusion concentrations has little influence on the UTS of as-rolled rods. A negative linear relationship between the logarithm of UTS and the logarithm of inclusion area fraction for cold-drawn samples is also obtained.
