に移動してノズル2を開閉する。FIG. 1 is a sectional view of a container for carrying out the method of the present invention. In the figure, ■ is a ladle, and 2 is a nozzle attached to the bottom of the ladle 1. The ladle 1 has an iron shell 1a and a large diameter lb provided inside the shell 1a, and the nozzle 2 has an upper nozzle 2a and a lower nozzle 2bt. 3 is an opening/closing device provided between the upper nozzle 2a and the lower nozzle 2b, and this opening/closing device 3 is a fixed brick:
3a and a slide brick 31), and the slide brick 31) moves horizontally to open and close the nozzle 2 by driving the j drive device U'4.

供給する。By the arrangement as shown in I-H, ff is added to the induction coil 5.
By passing a 1u current, the force in the upper nozzle 2a is induction heated and melted, and therefore the nozzle is clogged, and the molten steel is heated, so a drop in temperature of the molten steel at the final stage of pouring is prevented. . The induction coil 5 can stir the molten steel in the upper nozzle 2a, thereby preventing the slag from entering the final stage of Komagome. By changing the current value or frequency of the countercurrent, the dissolution time, stirring speed, and stirring intensity can be changed. The father current supplies Iu4 intermittently or continuously.
以上説明したように、この発明においては、安全確実に
、溶゛融金属を汚染することなくノズル話りを除去でき
る。As explained above, in the present invention, nozzle chatter can be removed safely and reliably without contaminating the molten metal.
