In this figure, 1 is a bottom cylindrical sump portion, and the center portion of the bottom 1a of this sump portion 1. is made of a rectangular non-magnetic metal plate 4, and the other parts are made of a steel plate. A cavity forming member 8 made of a nonmagnetic material is attached to the lower surface of the nonmagnetic metal plate 4 to cover the entire lower surface so that a cavity 5 is formed. This cavity forming member 8 has a structure in which a thin side wall with a low height is formed around a rectangular bottom plate. Here, FIG. 2 is a bottom view of the bottom portion 1a viewed from below, and the broken line shown in this figure indicates the shape of the cavity portion 5. As shown in FIG. One short side of this cavity 5 or 1
The tube 6 is connected to the other short side, and the v7 is connected to the other short side.

generates a linear moving magnetic field above it, which causes υ,
It stirs the molten metal υ, and the shape of the non-magnetic metal plate 4 mentioned above is this I! It is formed to have approximately the same shape as the top surface of the magnetic stirring device 10. On the other hand, 3 is a fireproof member provided with a certain thickness on the upper surface of the bottom part 1a, and 2
is molten metal.
