PURPOSE:To prevent molten metal leakage at a tundish nozzle part by burying a magnetic field generator in each block mold of a shifting type mold to generate eddy current in the molten metal. CONSTITUTION:Each magnetic field generator 6 in the plural block molds 1' at near the tundish nozzle 4 is worked among the block molds 1 shifted as rotating by a driving motor. Then, the shifting magnetic field is generated at the tundish nozzle 4 part, and as the result, the eddy current is generated in the molten metal 7, to generate a force toward progressing direction in the molten metal 7. Therefore, the molten metal 7 is flowed toward the shifting direction of the block mold 1' without inserting in the gap 8 between the tundish nozzle 4 and the block mold 1', and the casting sheet is formed continuously and smoothly. |
