Method and device for the electromagnetic stirring of electrically conductive fluids

A device for the electromagnetic stirring of electrically conductive fluids by using a magnetic field RMF rotating in the horizontal plane, and a magnetic field WMF traveling in a vertical direction, comprising at least

• a cylindrical container,
• a centrally symmetrical arrangement, surrounding the container, of at least three pairs of induction coils for forming a rotating magnetic field RMF producing a Lorentz force FL, and
• an arrangement, surrounding the container, of at least two induction coils lined up one above another in a stack coaxially with the axis of symmetry in order to produce the vertically traveling magnetic field WMF, and
• at least one temperature sensor for measuring the temperature of the fluid in the container and controlling the temperature by means of a control/regulation unit,
• wherein that a power supply unit is connected to the induction coils by the control/regulation unit, the power supply to the induction coils being performed in a fashion set by the prescribed conditions
• 0.2·ti.a.<TP,RMF=TP,WMF<2·ti.a. (I) or
• 0.5·TP,RMF<TP,WMF<5·TP,RMF (II).
