摘要 试验研究了电磁搅拌对铝偏析提纯中溶质径向分布的影响,并分析了产生不同分布行为的原因及理论依据,在此基础上结合试验结果得出了如下结论:(1)搅拌加快了热量在径向上的传导,使等温线弯曲度减小;(2)径向的偏析同等温线弯曲幅度成正比,随着搅拌强度的增加各溶质无论K0>1或K0<1径向浓度相对标准偏差有明显的降低趋势。 The study is about the effect of electromagnetic stirring on solute radial distribution in the process of aluminum segregation and purification,the causing reason and the theoretical foundation of the different distribution is analyzed,according to the above mentioned,and combining with the test results,the following conclusions can be get:(1)the heat conduction in the radial direction sped up by stirring,the curvature of isotherm is decreased;(2)this is proportional to the radial segregation and isotherm curvature,the relative standard deviation of each radial solute(wether K0>1 or K0 <1)has the obvious decreasing trend along with the increasing of stirring intensity.
