Abstract (en)

[origin: WO2017063811A1] The invention relates to an induction furnace for heating a workpiece consisting of metal, in particular to temperatures between 400°C and 1100°C, for industrial applications. The invention also relates to an extrusion press comprising an induction furnace and also to a method for heating a workpiece with the induction furnace. The object of the invention is to heat a workpiece with little expenditure of energy. To achieve the object, an induction furnace comprises a plurality of permanent magnets for generating a magnetic field in an interior space. There is a holding device, by which a workpiece can be held in the interior space for heating. There is a drive, preferably with a controllable speed, for producing a relative movement between the holding device and the permanent magnets.
