摘要： An apparatus for reforming rod-shaped, electrically conductive and/or magnetizable materials, in particular for drawing and extruding, having the following features: the apparatus has a female mold having a die, which forms the tool for reforming; the apparatus has an inductor of an electric linear motor, by means of which a traveling electric field can be produced; the inductor includes at least one first group at least with first coils; the first coils in the first group are arranged axially next to one another and thus form a channel; using the inductor it is possible to produce a traveling field in the channel which has a magnetic flux density having a gradient in the axial direction of the channel, which has an amplitude of greater than B=1 T.

摘要： The disclosure relates to a method for applying compressive and/or tractional forces to an essentially rod-shaped workpiece, according to which a mechnical engagement in the rod-shaped workpiece can be avoided. To this end, the method involves applying compressive and/or tractional forces to an essentially rod-shaped workpiece including an electroconductive and/or magnetizable material. A magnetic field is applied to the workpiece, including a gradient in the direction of the force to be applied. The disclosure also relates to a device for applying compressive and/or tractional forces to an essentially rod-shaped workpiece including electroconductive and/or magnetizable material. The device includes a coil arrangement that is supplied by a current and is designed to produce a magnetic field having a gradient.

摘要： A method for induction heating of a metallic workpiece to a desired temperature by rotating the workpiece relative to a direct-current magnetic field permeating the workpiece is provided. The workpiece is clamped between two clamping jaws adapted to be rotated about a common axis. At least one of the clamping jaws is driven to rotate, and at least one of the clamping jaws is adapted to be actively displaced along or parallel to the rotation axis. The contact force of at least one of the clamping jaws is regulated; moreover, at least one mechanical parameter representative of the workpiece temperature is measured as an actual value and is compared with a desired value of this mechanical parameter as being representative of the desired temperature.
