The electroslag remelting (ESR) process involves multiple interacting physical fields, including the electromagnetic field, flow field, temperature field, and concentration field. These fields are inherently coupled, resulting in a complex multi-field coupling system (Qiang in Study on the thermophysical behavior during the electroslag remelting process of the combined cycle turbine rotor. Northeast University, Shenyang (2016) [1]). The movement of metal droplets and the dynamic behavior of the slag bath/metal pool interface significantly alter the distribution of the electromagnetic field. Variations in the electromagnetic field subsequently influence the generation of Joule heating and Lorentz forces, which in turn affect the distributions of the temperature field, flow field, and concentration field.
