Abstract

PURPOSE:To rotate the molten steel in walls smoothly and horizontally by generating the rotating magnetic field of which the electromagnetic force along the long side walls of the side walls is smaller and the electromagnetic force along the short side walls is larger. CONSTITUTION:The AC of (u) phase of the ACs (u), (v) (where u<v) of two phases which have a phase difference of a pi/2 electrical angle to electromagnetic coils 4a, 4b, and differ in current values is flowed to the electromagnetic coil 4a of the convex magnetic poles on the respective long side walls and the AC of the (v) phase to the electromagnetic coil 4b of the convex magnetic poles of the respective short side walls. Electromagnetic forces F1-F8 act in a clockwise direction along the rotating magnetic field, and in the respective corner parts B, D where the thrusts of the molten flow flowing along the respective long side walls 6a, 6a' are larger than the thrusts of the molten steel flowing along the respective short side walls 6b, 6b' and turbulence tends to occur, the thrusts act in such a manner that the flow of the molten steel deviates from the corner parts; therefore, the occurrence of inclusion and turbulence is eased and the molten steel is smoothly flowed.
