2. Description of the Prior Art
In general, a metal fiber is used in a filtering system for lubricating oil or refined oil and a filler for conductive plastics. Conventionally, the metal fiber is produced by melting a plurality of metal bars. However, because there is an interval between the metal bars, there are much electric consumption wasted in melting the metal bars by a heating device, and thereby production efficiency of metal fiber to power consumption is lowered. Furthermore, because a device for feeding the plural metal bars is required, it is very complex in structure and is inconvenient in management of the device. In addition, a controlling system for keeping the metal bars in an even temperature or in a uniform speed are required.

DETAILED DESCRIPTION OF THE INVENTION
The present invention will now be described in detail in connection with preferred embodiments with reference to the accompanying drawings. For reference, like reference numerals designate corresponding parts throughout all views.
FIG. 1 is a schematic view of a metal fiber-producing device according to the preferred embodiment of the present invention, and FIG. 2 is a side view of FIG. 1.
The metal fiber producing apparatus according to the preferred embodiment of the present invention includes a rectangular frame 10, two induction coils 12 disposed horizontally in the inside of the frame 10 and a rotary disk 11 disposed horizontally at a lower portion of the induction coils 12.
The frame 10 is in a sealed structure and thereby metal fiber can be produced in a vacuum condition. The frame 10 may be filled with inert gas, such as argon or helium instead of the vacuum condition. The induction coils 12 are horizontally disposed at an interval in the inside of the frame 10. A metal plate 20 is dropped into a space between the induction coils 12 and then melted with heat generated by the induction coils 12 while passing between the induction coils 12. The rotary disk 11 rotating in a high speed is horizontally disposed at the lower portion of the induction coils 12. The rotary disk 11 has a plurality of blades formed vertically on a round bar, and the metal plate 20 dropped vertically is brought into contact with the blades of the rotary disk 11 and thereby extracted into a fiber form.
A method for producing metal fiber according to the preferred embodiment of the present invention includes steps of: making the frame 10 in a vacuum conduction by removing the air, dropping the metal plate 20 between the induction coils 12 and heating and melting an end of the metal plate 20 with heat generated by the induction coils 12; and bringing the end of the metal plate 20 into contact with the blades of the rotary disk 11 by moving the metal plate 20 gradually downward and separating and solidifying metal fiber.
In the step of making the frame 10 in the vacuum condition by removing the air, it is preferable that the pressure in the vacuum condition is 10−1˜10−3 atm. The frame 10 may be filled with inert gas, such as argon or helium instead of the vacuum condition. In this case, an oxidation of the metal fiber in a high temperature can be prevented.
Preferably, a thickness of the metal plate 20 is about 2˜15 mm, but may be adjusted according to materials of the metal plate 20. It is preferable that a heating temperature of the induction coils 12 is about 1,000˜1700° C., but it also may be adjusted according to the materials of the metal plate 20. A rotational speed of the rotary disk 11 is about 3,000˜5,000 rpm.
The metal fiber extracted by the blades of the rotary disk 11 is cooled and solidified. At this time, a cooling speed of the metal fiber is about 1,000˜100,000° C./sec. The rotary disk 11 is water-cooled. The extracted metal fiber is about 15 μm˜500 μm and it may be adjusted according to uses.
In the present invention, not a metal bar but the metal plate is used to extract the metal fiber and thereby production efficiency of the metal fiber is increased. Especially, the production efficiency of the metal fiber to power consumption is very increased, and manufacturing equipments are simplified.
While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated by those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
