Experiments on studying the rotation of slag and metal pools in the electroslag process in current-supplying mould were conducted. It is found that metal pool rotation can occur both due to the forces of friction from the rotating slag pool, and due to electromagnetic forces applied to the molten metal. Working current flowing through the mould current-conducting section, has a decisive influence on generation of the rotating effect. 13 Ref., 1 Tabl., 3 Fig.
