公平７−９１５７１号公報に記載されている。2. Description of the Related Art Conventionally, a method of tapping a levitation and melting apparatus of this type is based on, for example, reducing the current of a lower induction coil among upper and lower induction coils supplied with currents from separate power sources in the upper and lower directions to reduce the molten metal to a copper crucible. Japanese Patent Laid-Open Publication No. Hei 7-245182 discloses a flotation / melting apparatus in which hot water is discharged from an outlet at the bottom, and a flotation / melting apparatus provided with a control device for continuously controlling the operation from input of a material to be melted to hot water. Japanese Patent Application Laid-Open No. 10-38467 concerning the apparatus and its tapping method further discloses that a crucible made of a copper segment and having an opening at the bottom is mounted in a vacuum or an inert gas atmosphere to dissolve the titanium and make the titanium come into contact with the crucible. The skull is formed so that the molten titanium does not come into contact with anyone other than the skull, and after the melting is completed, the current of the induction coil wound around the outer periphery of the crucible is increased. Flip by flowing down the titanium melt from the bottom opening of the crucible, atomizing grinding the melt into particulate titanium blown substantially perpendicularly inert gas to the tapping stream is described in Japanese Patent Kokoku 7-91571.

きなかった。By the way, in a conventional flotation melting apparatus in which the amount of hot water is controlled by power control using upper and lower induction coils, the power of the lower induction coil is increased to increase the pinch force applied to the molten metal flow. In this case, if the diameter of the molten metal flow becomes smaller than a certain value, there is a limit that the pinch force does not allow the molten metal to be squeezed stably. According to the results of experiments with a practical levitation melting apparatus, the amount of molten metal was determined by the depth of the molten metal and the diameter of the outlet, and almost no adjustment was possible with the vertical induction coil.

It takes a long time, the control is impossible during this time, and the falling section is governed by the decrease in the head of the molten metal, and there is a section in which the constant amount of molten metal is not discharged. In these sections, for example, in the case of performing atomization, it is necessary to control the gas flow rate for atomization in accordance with the amount of hot water in order to keep the powder size constant.

材等の溶解に用いられる。In FIG. 1, when a material to be melted is charged into a water-cooled copper crucible 1 and currents are supplied to the induction coils 3 and 4 from AC power supplies 5 and 6, the currents are supplied to the induction coils 3 and 4. The magnetic flux generated by flowing into the copper crucible 1 passes through the slit 2 and interlinks with the material to be melted to induce an eddy current, and also induces an eddy current in the copper crucible 1. The material to be melted is heated by the eddy current induced in the material to be melted, and an electromagnetic force is generated between the material and the eddy current induced in the copper crucible 1. Since the two eddy currents are opposite to each other on the opposing surfaces, the electromagnetic force becomes a repulsive force. Since the copper crucible 1 is fixed, a levitation force is given to the material to be melted, and the material to be melted melts and floats. It becomes the melt 1a. The molten metal 1a melted in the copper crucible 1 does not come into contact with other objects at the time of melting, so that the amount of foreign matter is extremely small, even a material having a high melting point can be melted, the heat conduction loss is small, and the like. Therefore, it is used for dissolving a material requiring a high melting point and high purity, for example, titanium, a target material and the like.

ない。The molten metal 1a, which has been melted as described above, has its buoyancy reduced by the power control of the vertical induction coils 3 and 4, and flows downward through the nozzle 7 attached to the outlet 1b.
The amount of molten metal discharged per unit time is controlled to a desired amount by the inner diameter of the nozzle 7 and the drawing force of the induction coil 8 wound around the outer periphery of the copper crucible 1 where the nozzle 7 is mounted. Then, the powder 1 cooled by the gas blown out from the atomizing nozzle 9 below the nozzle 7
It becomes 0. The rising time until reaching a fixed amount of hot water is initially rapidly rising. From a certain amount, the amount of hot water gradually increases until the amount of hot water corresponding to the inner diameter of the nozzle 7 is reached. The nozzle inside diameter is selected so as to have a small value, and the nozzle is mounted on the outlet 1b so as to reach a desired amount of hot water quickly to shorten the rise time. In addition, at the time of constant-rate tapping following the tapping start, the tapping force of the induction coil 8 is used to control the constant tapping.
Further, in the last stage of tapping, it is possible to stop the tapping by solidifying the tapping flow in the nozzle 7 by stopping the current supply to the induction coil 8 and stopping the heating of the tapping flow to enhance the cooling of the nozzle 7. In this hot water stopping method, the nozzle 7
Until the molten metal in the tank can be controlled from the constant-rate tapping, it is not a problem because it is in a small quantity.

However, the diameter of the outlet at the bottom of the copper crucible 1 is reduced, and a large diameter tapping pipe is provided below the outlet. A nozzle may be attached to the tapping pipe part without providing a nozzle at the outlet.
