Abstract

An apparatus for electromagnetic stirring of the steel melt in an electrical arc furnace includes two electromagnetic stirrer units, a current supply, and a control unit. The two stirrers are mounted on an outer bottom surface of the electrical arc furnace at opposites sides of a central position of the bottom surface, the current supply is operatively connected to the two electromagnetic stirrer units, and the control unit is operatively connected to the current supply to control the operation of the two electromagnetic stirrer units.
