摘要： In taping for discharging molten metal (16) and slag (18) from a blast furnace, a pipe (30) is connected to the external end of a tap hole (12), and an electromagnetic energy supplying member (32) is disposed on the outside of this pipe (30) to apply. A turning motion or a magnetic pressure due to electromagnetic repulsion to the flow of melt in the pipe (30) so that the molten metal (16) and the slag (18) may be separately discharged at controlled speed. According to this method, the discharge quantity from the blast furnace can be kept substantially constant from the start till the end of tapping, the number of times of opening/closing of tapping can be remarkably reduced, and stability of product quality and saving of operations can be accomplished.
