“…It was found that the melt velocity was axisymmetric under linear EMS, and the grains in the EMS zone were isometric. Tao et al [10] established a two dimensional numerical model with multiple field coupling and used PLCO semi-solid model to describe the flow field of aluminum alloy paste. The results show that the electromagnetic field increases and the distribution is uneven when the stirring frequency and stirring current increase, which causes the velocity of slurry to increase rapidly and unevenly.…”

In the melting process of non-ferrous metals, melt stirring is one of the most important processes. In this paper, a new type of EMS (Electromagnetic Stirring) device with long service life and low energy consumption is designed based on the basic equations of Maxwell electromagnetics combined with finite element method. The effect of the designed EMS on the non-ferrous metal melt is studied. The 3D numerical model of multi-field coupling of DC EMS device is established. The distribution and morphological characteristics of magnetic field and flow field are simulated by ANSYS software. Through the streamline distribution and the volume fraction cloud diagram analysis, it is found that the melt flow state and the Si composition distribution are different under different stirring speed especially for early time, but when the time is long enough, the melt will be stirred evenly. During the stirring, the alternating magnetic field can form the circumferential electromagnetic torque, through which the non-ferrous metal melt can move. It is found that the circulating flow inside the melt and the shear flow near the groove wall are in conflict with each other. This phenomenon creates favorable conditions for the collision, friction and mixing of non-ferrous metals and reinforcement groups.

“…Therefore, the microstructure is non-uniform. The primary grains are relatively small and slightly spherical in outer layer but are relatively larger and rosette-like or dendritic in inner of the slurry, as a result, the quality of billet is poor [10][11]16].…”

The electromagnetic stirring combined with mechanical stirring (EMSCMV) method was developed for preparing the AlSi9Mg alloy semi-solid slurry. The experimental results demonstrate that, the preparation of semi-solid slurry by EMSCMV is sufficient to obtain fine microstructure of billet. The primary -Al particles are small, spherical and uniform throughout the microstructure. When increasing the stirring power and the vibrating power, the size of primary -Al particles decreases while the shape factor increases, and its distribution is more uniform. The fine microstructure of billet prepared by EMSCMV was obtained at the stirring power of 2.0~2.4 kW and vibrating power of 0.8 kW.
