Abstract
The mathematical models describing motion and heating of molten metal droplets in a liquid slag layer at the process of traditional
electroslag remelting have been developed, assuming that the droplets have a spherical shape or deform to a spheroids
flattened in their movement direction. The deformation of metal droplets impacts the velocity of their motion, making more
efficient their heating while falling through the molten slag layer because of the bigger midsection and surfase areas of the
deformed droplets at the same volume and mass. The differences between the predicted characteristics of motion and heat up
of spherical and deforming droplets in the slag layer are more significant for the droplets of large size.
