れている。In these methods, a tundish method has been adopted in order to enlarge the hot water pool to enable large-scale processing. However, particularly in the system provided with the stopper, the runner is squeezed from the tundish to the nozzle tip having the spout of the molten metal. An example of such tundish system will be described with reference to FIG. A tundish nozzle 4 is provided at the bottom of the tundish 1 for storing the molten metal (molten metal) 2, and an intermediate nozzle 5 and a nozzle holder 6 are connected to each other to form a molten metal passage.

面に飛散し付着する。As shown in FIG. 7, the nozzle holder 6 has an end portion of the flow path 9 for the molten metal and a spread portion 10 that spreads abruptly from the opening of the flow path 9, and the front surface of the spread portion 10 The nozzle tip 7 is fixedly installed in the. As shown in FIG. 6, the molten metal 2 in the tundish 1 is jetted from the nozzle slit 8 through the molten metal flow passage 9 by the rise of the stopper 3, and is rapidly cooled by the cooling roll R and the ribbon (metal ribbon) 11 Is formed. However, at this time, since the melt flow path 9 is narrow, the flow velocity of the melt increases and a large amount is ejected to the central portion as shown in FIG. The shape is separated into three as shown in Fig. 2 (b). Then
When the molten metal pressure of the entire spreading portion is increased, a merging occurs between the molten metal flows I and II and the shape becomes a steady state. The collision of the molten metal occurs when the molten metal flows merge. In this way, the non-uniform molten metal flow phenomenon at the start causes collision of the molten metal at the nozzle tip, and as a result, splash occurs and scatters and adheres to the front surface of the nozzle.

To solve
A control plate for controlling the flow rate of the molten metal is provided in the nozzle holder.

る。The flow of hot water in the apparatus of the present invention is as shown in Fig. 1 (a).
The molten metal that has flowed into the expanded portion 10 of the nozzle holder collides with the central portion of the control plate 12 and branches into the edge portion, and flows out of the nozzle tip 7 at substantially the same flow velocity by the holes 15 and 16 in FIG. The middle part of both parts also flows out with a slight delay due to the low flow velocity in both parts, and as a result, the first part
The tip of the ribbon 11 is almost flattened as shown in FIG. As a result, no violent collision of the molten metal on the front surface of the nozzle tip 7 occurs and no splash occurs. Further, when the structure as shown in FIGS. 3 and 4 is used, the rectification in the spread portion is promoted, and the uniformization of the molten metal flow becomes more remarkable. As a result, there are no vertical streaks or vertical cuts. As described above, according to the device of the present invention, the shape of the ribbon at the start portion is improved, and further, the improvement is effective in reducing the plate crown. FIG. 5 shows the ribbon thickness (μm) at the position in the width direction of the ribbon with and without the control plate (A-with control plate, without B-control plate). It shows that there is an effect.
