METHOD FOR INDUCTION HEATING OF A METALLIC WORKPIECE

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 rendered distinct by the features that the workpiece is clamped between two clamping jaws adapted to be rotated about a common axis, that at least one of the clamping jaws is driven to rotate, that at least one of the clamping jaws is adapted to be actively displaced along or parallel to the rotation axis, that the contact force of at least one of the clamping jaws is regulated, and that 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.
