Abstract
This study explores the effect of rotating magnetic fields on the quality of casting low-carbon steel. Magnetic casting influences the molten metal flow through a controlled permanent magnetic field, which optimizes heat dissipation and induces fluid stirring within the mold. Our simulations reveal that a rotating magnetic field can enhance crystal fragmentation and improve microstructure homogeneity by inducing a vortex in the superheated region of the molten metal. The impact of variables, including the distance and magnetic flux density of the permanent magnet, was analyzed, showing their influence on the molten metal flow and casting outcomes. Experimental results, supported by modeling, highlight that higher magnetic flux densities contribute to a more uniform microstructure. This approach can refine casting processes, reduce defects, and promote structural consistency. Our findings offer valuable insights for optimizing magnetic-assisted casting technologies for enhanced metal solidification and improved casting quality.
