A device for inductively heating the edges of elongated movable workpieces, includes an inductor having vertical pole surfaces disposed one above. The edge of the elongated movable workpiece is maintained at a given distance from and completely outside the inductor, so that the workpiece cna move up and down completely freely relative to the inductor.

Device for inductively heating the edges of elongated moving workpieces

An inductive heating apparatus for forging ingots which are pushed in a row through the apparatus for thoroughly heating them and subsequent transport includes a friction disc type of drive engaging the ingots as they enter the inlet end of the heating apparatus. A thyristor-controlled d.c. shunt motor is used as the drive for the friction discs and the speed of this motor is controlled by a regulating device which is programmed for alternate low and high speeds, the low speed matching the required staying time of each ingot in the inductor heater necessary to thoroughly heat the same, and the high speed being used to effect a fast discharge of the heated ingot from the apparatus.
