す。Conventionally, in continuous casting in which the number of strands is two or more, as shown in FIG. 6, a tank having a hot water receiving portion 15 and a hot water outlet portion 17 having a number of hot water outlet holes 16 corresponding to the number of strands is formed in a T shape. The dish 18 is generally used, and the molten metal received in the hot water receiving portion 15 is distributed to the mold (not shown) of each strand through the hot water outlet 17 of the hot water outlet portion 17 for casting. In the figure, 19 is a hot water receiving portion 15 for floating and separating inclusions in the molten metal.
The tundish weir provided between the hot water and the hot water outlet 17 is shown.

However, when this low temperature casting was performed in the tundish 18, it was difficult to maintain the melt superheat temperature (ΔT), and it was difficult to perform stable low temperature casting.

ある。Due to the background of the continuous casting technology as described above, in recent years,
In order to improve the quality and operation of slabs in continuous casting, a tundish for continuous casting in which an induction heating device is provided in the tundish is proposed, and the number of strands is used as a tundish for continuous casting equipment having two or more, For example, as shown in FIG. 7, the hot water outlet portion 20 is divided into two hot water outlet chambers 22 and 23 by a hot water receiving chamber 21, and a molten metal passage 24 is provided between each hot water outlet chamber 22 and 23 and the hot water receiving chamber 21. Induction heating cough 25
The tundish 26 which has been provided has come to be proposed. (See Iron and Steel, No.12 VOL.73 SEPT.1987, pages 192-193) [Problems to be solved by the invention] However, in the tundish 26 having the above-mentioned configuration, the hot water receiving room 21 and the exit room 22 Although having the effect of retaining the molten metal overheating temperature (ΔT) in the molten metal passages 23 and 23, the molten metal passages 22 and 23 are provided on the left and right sides of the molten metal receiving chamber 21, and the molten metal passages are provided between the molten metal heating chambers 22 and 23 and the molten metal receiving chamber 21. Since the induction heating weir 25 having 24 is provided, the space between the right and left strands is widened, the continuous casting equipment becomes large, the installation space is large, and the induction heating weir 25 is required on the left and right sides, which is extremely unfavorable. In addition to being economical, there is a problem that it is difficult to apply to the tundish of the existing continuous casting equipment with a narrow strand interval.

The object is to provide a tundish for continuous casting which can be applied to casting equipment.

操業改善が図れる。An induction heating weir is provided between the two hot water discharge chambers, and the inside of the induction heating weir is made to communicate with the space between the two hot water discharge chambers and the hot water receiving chamber.
Since the molten metal passage is provided by connecting the molten metal passage between the two hot water discharge chambers or between the hot water receiving chamber and the hot water discharge chamber, the tundish can be formed compactly, and therefore the strand spacing of the continuous casting equipment can be reduced. It can be made narrow and can be applied to continuous casting equipment with narrow strand intervals. Moreover,
During casting, the molten metal from the hot water receiving chamber can be heated by induction heating and sent to the two tapping chambers at the same time. In the tapping chamber, the pinch effect of induction heating (the action of sucking and discharging the molten metal into the molten metal passage) ) Flow and stirring is performed,
The molten metal can retain heat, and at the same time, the molten metal in the tapping chamber can be evenly heated. Therefore, low-temperature casting in which the molten metal superheat temperature (ΔT) is lowered can be effectively performed, and the quality and operation of the slab in continuous casting can be improved.
