The study examines the current state of research on electroslag remelting (ESR), which combines experimental methods with numerical modeling to describe the motion of metallic droplets in the slag bath. Particular attention is paid to the influence of fluorine–oxide slag composition on the density and viscosity of the melt, which determine the kinematic characteristics of droplets and the efficiency of metal purification. The proposed generalized empirical equation adequately describes the velocity of small and medium droplets within the density range of 2800-3500 kg/m³ and viscosity of 0.2-0.6 Pa·s. It is shown that droplet diameter is a key factor in thermal equalization: small droplets heat uniformly, whereas large ones retain temperature heterogeneity. The modeling results confirm the applicability of the equation as an approximation model for predicting ESR processes and highlight prospects for its refinement by considering droplet deformation and multifactorial effects.
