Abstract

PURPOSE:To remove safely and surely the clogging in a nozzle by heating inductively the molten or solidified metal in a nozzle of a vessel for molten metal. CONSTITUTION:The nozzle 2 in the bottom of a ladle 1 has an upper nozzle 2a and a lower nozzle 2b, and the sliding brick 3b of a opening/closing device 3 provided between the same moves horizotally with respect to a stationary brick 3a thereby opening and closing the nozzle 2. An induction coil 5 is provided at the circumference of the nozzle 2a and when AC current is conducted to said coil, the solidified steel in the nozzle 2a is inductively heated to melt. The clogging in the nozzle is thus safely and surely removed without contaminating the molten metal.

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:

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.
