ABSTRACT OF THE DISCLOSURE A method and apparatuis for stirring the non- solidified regions of a cast strand, the strand being formed in a mold of a continuous casting machine, is disclosed. Molten metal enters the mold in a tap stream or jet from a casting pipe or enters by direct injection into the mold. A static magnetic field is generated across the mold and acts in the path of the tap stream in the melt in the mold. The magnetic field, due to the movement of the metal stream, retards the velocity of the tap stream in the melt and splits the tap stream, thus stirring the melt. The magnetic poles which generate the static magnetic field are positioned substantially adjacent the casting pipe or the mold so that certain portions of the melt will be located at the side of the casting stream and will not be directly influenced by the stream. These portions, upon retardation of the stream, will be stirred by the interaction of the magnetic field and the currents produced in these portions. - 10 -
