The molten copper flow is poured so as to directly hit the fixed mold 13 side. In other words, it is possible to pour the molten metal without directly applying the molten copper flow to the wheel mold 11, and the life of the wheel mold 11 can be extended, and the surface roughness of the groove 12 is reduced, so that the surface during contraction when the molten copper M solidifies is reduced. The sliding becomes smoother and more complex molds can be used.

The cross-sectional shape of the groove of the wheel mold shown in the embodiment is changed so that a flat plate, for example, an anode plate, is made continuously, so that the groove 32 has a small groove depth. There is. By the way, when performing such flat plate casting, it is preferable to use the fixed mold 13 shown in FIG. 5 and to apply the molten copper flow to the fixed mold 13 with a large inclination angle θ. Further, by selecting the shape of the groove of the wheel mold, it is possible to continuously cast ingots having various shapes.

る。(Effects of the Invention) As explained above, according to the present invention, the fixed mold can be provided opposite to the groove of the wheel mold, and the fixed mold can be slid as the wheel mold rotates as necessary. Since the cast ingot is guided by guide rollers, there are no accidents such as replacement or cutting of the belt due to its lifespan, which occurs in conventional devices using metal belts, and it is also possible to replace the fixed mold as necessary. Since seizure can be prevented by sliding, there is no need to interrupt continuous casting work, which has the effect of greatly improving work efficiency.

なく、該矯正による品質の悪化もない。 In addition, the fixed mold has a substantially rectangular parallelepiped shape, and the surface facing the groove of the wheel mold is flat, and the contact area with the molten copper is relatively small, so it is affected by the heat from the molten copper. The life of the fixed mold is extended. In addition, as mentioned above, since the contact area of the fixed mold with the molten copper is small and the resistance is small, the sliding operation of the fixed mold can be smoothed, and wrinkles etc. can occur on the skin of the copper plate being manufactured. A high-quality product can be obtained with less oxidation. In addition, since the copper plate as a product is not bent into an arc by the fixed mold during the manufacturing process, there is no need to straighten the arc-shaped copper plate into a straight shape, and the quality deteriorates due to such correction. Nor.
