Abstract
Different schemes of producing the effect of slag pool rotation are considered. The rationality of achieving this effect without application of additional power sources or devices for electromagnetic impact on the slag pool is shown. Experiments were conducted in two types of moulds, namely current-supplying and regular modifications. It is established that in order to achieve the defined goal it is rational to apply current-supplying moulds with one or several cuts and current-supplies in the current-supplying section.
