The instant invention is concerned with the casting of metal fibers, preferably ferrous fibers, by the melt extraction technique. The metal to be cast as a fiber is in the form of a rod which is brought into contact with a spinning wheel having a tapered perimeter. The rod is heated by electromagnetic induction by a specially designed, slightly curved spiral coil. The coil is shaped to focus the heat at, or close to, the tip of the rod so to induce a meniscus. The rod is fed the through an opening in a guide that acts as a heat sink to carry away excess ...
Apparatus for fabricating metallic fibers having a small cross section, comprising: a guide having a generally vertical, longitudinal opening extending therethrough, an induction coil located at the upper end of said guide with the center of the turns of said coil being proximately coaxial with the axis of said opening, a wheel having a tapered portion around the perimeter thereof, said tapered portion of said wheel being in general alignment with the axis of said opening, and means for rotating said wheel. A method for fabricating metallic materials hav...
