| description | This paper focuses on the electromagnetically stirred process for manufacturing the material required for the semi-solid forming method. The maximum weight of the molten metal used at a laboratory scale in the currently published research is 3 kg. However, a large-scale electromagnetic device is needed when using a material with a maximum weight of 5 kg or more of the molten metal used in the actual industry. Therefore, controllers in this study are installed at each pole in the electromagnetic stirrer, which has six poles in order to stir materials weighing 5 kg or more. The current is input to the adjacent pole counterclockwise (CAMP), and to the symmetrical poles counterclockwise (CSMP). The experiment results show that the current method input to the CSMP can generate the highest electromagnetic force at the center of molten metal. A phase analysis is performed for the size and the roundness of primary α-Al particle from the material prepared by different input currents. The degree of roundness of primary α-Al particles is better when the current is input to the symmetrical poles counterclockwise. |
