A device for continuous or semi-continuous casting of metals, comprising a casting mold ( 1 ) which is open in both ends in the casting direction, means ( 2 ) for supplying melt to the mold ( 1 ), a first electromagnetic induction coil ( 4 ) energized by A.C. current and adapted to induce a stirring motion to the melt ( 7 ) in the mold ( 1 ), and a second electromagnetic induction coil ( 3 ) arranged upstream of the first induction coil ( 4 ) and adapted to control the stirring motion of the melt in the region adjacent to the upper free surface ( 5 ) of the melt. The second induction coil ( 3 ) is arranged to be interchangeably energized by either D.C. or A.C. current. The invention also relates to methods for control of stirring motion in a casting mold ( 1 ).
