PURPOSE: To stably keep the temp. of a molten metal uniform by setting a plasma heating device between both nozzles of a ladle and a tundish and an electromagnetic molten steel stirring device near the heating device.
CONSTITUTION: The molten steel 2 is poured in the tundish 10 from the ladle incorporating the molten steel 2 through the ladle nozzle 3 and further, poured into a mold through the tundish nozzle 4 to execute continuous casting. Then, the plasma heating device 5 for heating the molten steel 2 is set between the ladle nozzle 3 and the tundish nozzle 4. Further, the molten steel stirring device 11 for stirring the molten steel with electromagnetic force is set near the plasma heating device 5. An AC linear motor electromagnetic coil or an electric magnet is used to the molten steel stirring device. By this method, inclusion brought in the mold can be reduced.
