    摘要: Method and apparatus for melting rod-shaped material 12. This is continuously displaced in the direction of the rod axis towards an induction coil (5), disposed at the lower end (12a) of the rod, which has an opening coaxial with the rod and which is supplied with an alternating current. An induction coil (5) is used of which the axial dimension is several times smaller than the radial dimension. Preferably, a so-called flat-coil is used. The induction coil has an opening (5c) which is smaller than the rod diameter. On melting the lower end (12a) of the rod is held with its end face at a substantially constant spacing above the induction coil (5). The method and apparatus are suitable for the production of metal powder and for the direct production of shaped parts.
