Figure 2 shows the case where no convection suppression method of the molten metal in the crucible is taken.The molten metal 5 is heated by the electron beam 3, but is cooled by the cooling pipe 2, so the electron beam 3 Convection 4 as shown by the arrow occurs inside the molten metal due to the temperature difference between the electron beam 3 and the incident part.
The molten metal heated to a high temperature at the entrance part moves by convection and heats part A of the crucible. Therefore, part A of the crucible was attacked by the heat and convection of the molten metal, and this part was most susceptible to damage.

1. Convection is suppressed by the convection suppression matrix 7, but when melting extremely corrosive metals, the convection suppression matrix 7 will be corroded by the corrosive metal and gradually become ineffective. However, if the convection suppressing matrix 7 is made of a material that easily forms an alloy with the molten metal, the convection suppressing matrix 7 will form an alloy with the molten metal and similarly gradually become ineffective.

2、このような形状の対流抑制マトリクス7は対流は抑

2. Although the convection suppression matrix 7 having such a shape can suppress convection, it cannot suppress radiant heat dissipation from the surface of the molten metal 8 because its area covering the liquid surface of the molten metal 8 is small.

ない。
3. The convection suppression matrix 7 needs to be placed in the crucible to suppress convection, so it has a considerable size, so even if it corrodes or melts, it cannot be easily replenished from the outside. The shape of the convection suppression matrix 7 needs to be different depending on the shape, and it is not possible to use the same shape of the convection suppression matrix 7 for all crucible shapes.

ない場合がある。
4. There is no problem if all the metal in the crucible is melted, but if any part of the metal touching the convection suppression matrix 7 does not melt and becomes a solid phase, the convection suppression matrix 7 freely melts into the molten metal. The molten metal may not be able to float, and a portion of the molten metal may excessively protrude from the surface of the molten metal, or may be restrained by the solid phase metal at the bottom of the crucible, resulting in a failure to exert a sufficient convection suppressing effect.

という問題点があった。There was a problem.

In the case of the embodiment shown in Fig. 4, the convection suppressing plate 9 is inserted into the molten metal from above, so if the convection suppressing plate becomes worn out, it can be easily replenished by sending in new convection suppressing plates from above one after another. All problems are the same as those of the known example shown in FIG.

In order to solve these problems, in the present invention, instead of the conventional large convection suppressing matrix or convection suppressing plate fixed to the top of the crucible, mutually independent floats of arbitrary shapes made of molten metal or its alloy are used. It floats on molten metal in a crucible to replace convection suppression plates, convection suppression matrices, etc. No matter how much the liquid level of molten metal fluctuates, its effect remains the same, and it can also be applied to partial melting, and it can be used as a convection suppression plate or convection suppression matrix. It is easy to replenish when needed, and has good thermal efficiency because it suppresses radiant heat dissipation.

In other words, the float is made of a material with a melting point equal to or higher than that of the molten metal, and its specific gravity is reduced, or the float is made hollow or sponge-like so that parts of it can be placed independently on the surface of the molten metal. The float is constructed so that it floats on the surface of the liquid, and then the float is naturally brought to the edge of the crucible, that is, the periphery of the molten metal surface, by the convection of the molten metal, and the float is placed below the surface of the molten metal. The sunken part acts to prevent convection currents from directly hitting the crucible.

表面からの輻射放熱が抑制され放熱率が向上する。
Furthermore, since the float widely covers the surface of the molten metal, radiant heat radiation from the molten metal surface is suppressed and the heat radiation rate is improved.

An embodiment of the invention is shown in FIG. A crucible 33 having a cooling pipe 34 stores molten metal 39 to be evaporated, and a linear electron beam 32 is generated from a linear electron gun 31.
The melt reaches the center of the crucible and forms an extremely high-temperature evaporator 35, from which metal vapor is generated upwards.Most of the liquid surface of the molten metal 39, except near the evaporator 35, is floating In this embodiment, the float 36 is made of the same composition as the evaporated metal, and the molten metal lost due to evaporation is supplied as a replenishment float 38 through the float supply trough 37. That is, in the case of this embodiment, the float 36 is a sponge-like float and has a bulk specific gravity smaller than that of the molten metal, so it floats on the surface of the molten metal until it melts, suppressing convection in the crucible during that time. It also plays a role in suppressing heat radiation from the molten surface.

Another embodiment of the present invention is shown in FIG. 5. The crucible has the same structure as the conventional crucible, and the molten metal 14 is made of a metal having a higher melting point and lighter specific gravity than the molten metal 14. Specifically, when melting copper (specific gravity 8.93°, melting point 1083°C), for example, iron (specific gravity 7.86, melting point 1536°C) is used as the float. The center of the liquid surface of the molten metal 14 is heated by the electron beam 3, and convection 13 occurs in the molten metal (liquid phase') 14-1.The floats 12 are initially scattered evenly in the molten metal, but convection occurs. The float 12 is carried by the molten metal (liquid phase) 14-1 and is gradually blown closer to the crucible. Molten metal 1
The head of 4-1 is slightly above the liquid level, and the rest is almost submerged in the molten metal, so convection 13
The convection current flowing toward the crucible wall just below the surface of the molten metal, which has the highest temperature, hits the float 12 and changes its direction downward before reaching the crucible wall, so the temperature of the crucible wall is sufficient. Lean low.

Further, according to the present invention, the float 12 floats so as to adhere to the wall surface of the crucible, and if highly abrasive powder or solids are mixed in the molten metal, the convection speed is high and abrasive wear on the wall surface of the crucible occurs. It is also effective as a countermeasure if it becomes a problem.

Furthermore, even if part of the molten metal solidifies and becomes a solid phase ↓4-2, the float 12 surrounded by the solid phase 14-2 will not move due to convection, but the float in the liquid phase will move freely. It never loses its effectiveness.

旦固相中に取り込まれた浮き子も再び同相が液相に変わ

The effect of floats once incorporated into the solid phase can be restored if the same phase changes to the liquid phase again.

The spherical float 15 has the simplest shape, and is made of metal or ceramic, which has a higher melting point than molten metal and has a slightly lighter specific gravity, or a combination of both.
It may also be made of the same metal as the molten metal (if the metal expands in volume during solidification, it will float on the surface of the molten liquid even if it is made of the same metal as the molten metal).

Sponge-like floats are used when the same metal as the molten metal is used as the material for the float; in other words, molten metal is supplied to the crucible by placing the float into the crucible. shape float 19
For a while, the molten metal does not seep into the interior due to the action of surface tension, so it floats on the surface of the molten metal and acts as a float, preventing the crucible wall from getting too hot, but it gradually melts, until it completely melts. Once this happens, the sponge-like float loses its effectiveness as a float, so the sponge-like float is constantly replenished with new material little by little.
