Analysis of current state and perspectives of electroslag metal surfacing technology development in current-supplying mould has been performed, the feasibility of conducted research on the specified process is justified. The nature of the studied process and the role of the slag pool in electroslag technologies are described. For a deeper understanding of the features of the electromagnetic influence on hydrodynamic processes in a liquid slag pool, a three-dimensional mathematical model that describes the interaction of the electromagnetic field of the current-supplying section of the mould for electroslag surfacing with liquid slag has been formulated taking into account the deformation of the free surface. Using modern numerical modeling methods, a study of electromagnetic and hydrodynamic processes has been conducted having as an example a sectional mould with a diameter of 180 mm, containing a protective graphite lining of the upper section. Based on the obtained modeling results, for different positions of the power terminal of the current-supplying section of the mould an analysis of the distribution of electric current in the volume of the slag pool has been carried out, the nature of the movement of liquid slag has been investigated, the dependence of the average velocity of liquid slag has been established, and the shape of the free surface has been obtained. Zones of maximum heat release have been identified, current density distributions in the upper section of the mould and the slag pool have been shown, and profiles of the azimuthal velocity of slag on the free surface and on the boundary in contact with the deposited metal layer have been determined. It has been established that the azimuthal displacement of the upper section current terminal allows to control effectively the liquid slag circulation intensity in the mould.
