Abstract
The results of numerical modelling of electromagnetic processes in the system of electroslag surfacing of metal with sectional mould for different positions of the terminals of the current supply, which is made on the basis of the developed mathematical model. The results are presented in the form of current density distributions in the metal of section with a vertical slit and electromagnetic forces in the liquid slag. It is shown that the azimuth displacement of the upper terminal of the mould, which is connected to the current-carrying section, relative to its vertical slit significantly affects the electromagnetic forces in the slag bath, but does not change the heat output in the system. At the same time, the position of the lower terminal connected to the workpiece has virtually no effect not only on heat dissipation, but also on the forces in the liquid slag.
