題がある。By the way, in the conventional configuration, the molten metal is in contact with a crucible made of a refractory material such as ceramic or graphite, and the gas, ceramic or graphite from the crucible is melted or kept warm during melting. There is a problem of contamination by contamination. In addition, since the crucible made of ceramic or graphite is eroded or oxidized, it is difficult to continuously cast a refractory metal. In addition to the above, for example, in the case of a hard and brittle metal, there is a problem that even if an ingot can be manufactured, a processing method such as a rear right extrusion method or a Mannesmann perforation method cannot be adopted.

In FIG. 1, members denoted by the same reference numerals as those of the conventional example have approximately the same functions, and therefore description thereof will be omitted. In FIG. 1, reference numeral 10 denotes an outlet 10a which is formed in a cylindrical shape with a bottom and discharges a molten metal 11 formed at the bottom, and a lower part of the outlet 10a has a tapping pipe portion having a larger diameter than the outlet 10a and a cylindrical portion. A crucible made of a good conductive metal having vertically long slits provided radially at substantially equal intervals, 12 is an upper induction coil provided on the outer diameter side of the crucible 10, and 13 is a lower induction coil provided on the outer diameter side of the crucible 10. Induction coils, 14 and 15, are AC power melts for individually supplying high-frequency current to the upper and lower induction coils, and 16 is a substantially cylindrical body provided by a cylindrical body provided on the outer peripheral side thereof and projecting from the inner surface of the cylindrical body. A die (see FIG. 2) formed to be supported at the center and mounted on the outlet 10a to cast the molten metal 11 into a tube. A die 17 supports the die 16 and a part thereof is provided below the outlet 10a. Outflow port 1 A die support pipe mounted on a tapping pipe section having a diameter larger than a, a cooler 18 closely disposed on an outer peripheral side of a die support pipe 17, and a die 19 mounted on a die 16 to prevent molten metal from leaking during a melting period. At the same time, a dummy tube 20 serving as a starting block at the time of casting indicates a dummy tube 19 and a pinch roller for pulling out the cast tube 21 at a predetermined speed.
As will be described later, the upper induction coil 12 is provided so as to mainly apply the melting energy to the molten metal 11, and the lower induction coil 13 is provided so as to mainly apply the levitation force to the molten metal 11.

ないように水冷されている。A material to be melted is put in the crucible 10, and as shown in the principle diagram of the levitation melting furnace in FIG. 3, magnetic fluxes generated in the induction coils 12, 13 are electrically insulated from each other. In addition to inducing eddy currents in the crucible-constituting metal between the slits, the eddy currents enter the crucible 10 through the gaps of the slits, interlink with the material to be melted, and induce eddy currents in the material to be melted. The directions of the eddy currents flowing through the crucible 10 and the material to be melted are opposite to each other at the opposing surface portions, so that magnetic repulsion occurs. Since the crucible 10 is fixed, the levitation force is applied to the material to be melted. If the buoyancy is greater than the weight of the material to be melted, the material to be melted is crucible 10.
Levitate away from. The material to be melted generates heat due to resistance loss and continues heating. Further, since the eddy current induced in the crucible 10 also heats the crucible 10, the crucible 10 is water-cooled so as not to melt.

源１４から供給されることが行われている。Here, in order to prevent the material to be melted from coming into contact with the crucible 10, it is desirable that the material to be melted be stably positioned at the central portion of the crucible 10. In order to stably levitate in the crucible 10, it is necessary to increase the electromagnetic repulsive force from the crucible 10 against the weight of the material to be melted toward the bottom of the crucible. In order to increase the electromagnetic repulsion at the bottom of the crucible, a current is supplied to the lower induction coil 13 wound around the bottom of the crucible from an AC power supply 15 having a lower frequency so as to obtain a larger levitation force than the upper induction coil 12. A high-frequency current for melting the material to be melted is supplied from another AC power supply 14 to the upper induction coil 12.

の中央まで挿入する。By using a floating melting device as a device for melting and keeping the temperature of the metal used in continuous casting, the molten metal does not come into contact with other objects during melting, so that there is very little foreign matter mixed in, and even a material having a high melting point can be used. Features such as the ability to dissolve and the small heat conduction loss can be used. And
The continuous casting device is an outlet 1 of the crucible 10 of the flotation melting device.
In order to solidify the molten metal 11 while passing through the die 16, a cooler 18 is provided in close contact with the outer peripheral side of the die support tube 17. Weld the molten solidified in 16,
A dummy tube 19 serving as a starting block for pulling out at an appropriate speed through a pinch roller 20 is inserted. The dummy tube 19 prevents the molten metal from dropping during the initial stage of melting, and when the melting is interrupted due to a power failure during the melting or a failure of the power supply system, etc.
Is used to prevent burning of the pinch roll 20 and other devices below the crucible 10 at a speed higher than the speed of solidification in the die 16 and to avoid scattering of the molten metal 11. When casting the pipe 21 with the above configuration, first,

After dissolving the metal in 0 to form a floated molten metal 11 and make it ready for tapping such as component adjustment and hot water temperature adjustment, the coil currents of the upper and lower induction coils 12 and 13 are adjusted to place the molten metal in the die 16. After casting, the molten metal 16 is welded to the dummy tube 19, and the dummy tube 19 and the tube welded to the dummy tube 19 are continuously drawn downward by the pinch roll 20 to continuously cast the tube 21. In the above description, the molten metal 11 is

It is important to select a combination of the metal and the die that has as little reaction as possible. . However, since the contact area between the metal and the die is small, and the temperature of the metal is close to the solidification temperature at the contact portion, the entire crucible, such as a refractory crucible,
In addition, compared with the case of contact at a high temperature, impurities are less likely to be mixed into the metal due to the contact reaction, so that it is practically no problem.
