Furnace systems and methods for stirring a metal material

Abstract

The disclosure describes a furnace system and a method for electromagnetic stirring of a metal melt. The furnace system includes a furnace for melting a metal material and a stirring system. The stirring system consists of at least two electromagnetic stirring units. The electromagnetic stirring units are located beneath the furnace on the vertices of an N-polygon. N is the number of electromagnetic stirring units. Each electromagnetic stirring unit is configured to induce a force on the metal material along a main direction of each electromagnetic stirring unit. The projection of the main direction of each electromagnetic stirring unit into a horizontal plane defines a main axis of each electromagnetic stirring unit. Each main axis of each electromagnetic stirring unit essentially passes through the center of the N-polygon.
