Rotating magnetic field (RMF) of commercial frequency is used in pilot scale of horizontal continuous casting of CuNi10Fe1Mn alloy hollow billets. The effect of RMF on solidification macrostructure, element distribution and mechanical properties is studied. The result shows that the formerly inhomogeneous columnar grain macrostructure turns into homogeneous equiaxed grain macrostructure with the application of RMF, the average grain size reduces from 6.1 to 0.56 mm and the element segregation is restrained, the ultimate tensile strength is increased by 20.3% and the elongation is improved by 65.7% compared to those without RMF. Moreover, the action mechanism of RMF is discussed to explain its effect on improving the solidification macrostructure, element distribution and mechanical properties.
