Study on magnetic properties and domain structures of Fe-(5, 6) wt% Si alloys prepared with high purity metallurgy
説明
The hysteresis loss of silicon iron alloy is highly connected to the crystal defects caused by impurities, stress and so on, which contribute to a pinning effect of magnetic domain wall displacement and rotation, thus results in an increase of iron loss[1]. Therefore, highly pure silicon iron alloy is always desired among industries and researchers. In order to obtain high purity iron silicon alloy in the experiment, highly pure raw iron and silicon with a purity of 99.99 wt% were utilized, and a method called CCLM (Cold Crucible Levitation Melting), which is popular for high purity metallurgy of various materials, was introduced to melt raw materials. In CCLM furnace, during melting by electromagnetism induction heating, the melted alloy can avoid contacting the crucible because it is levitated by magnetic force simultaneously that can effectively reduce impurities of the alloy than other metallurgy.
