Abstract
1. Arrangement for heating workpieces (W), especially tubes or rods, by induction, using a plurality of inductors (L1 , L2 , Ln ) which with capacitors (C1 , C2 , C3 ) form a plurality of individual resonant circuits (L1 , C1 ; L2 , C2 , Ln , Cn ) powered by a common a.c. source, the current supply to said resonant circuits being adapted to be connected and disconnected individually and/or in groups by a controlling system (V, E) in response to a deviation in the temperature of the workpiece, said controlling system (V, E) only connecting the supply of current to one or more individual resonant circuits if the voltage from the a.c. source disappears at least for the switching instant, characterised in that the a.c. source is a controlled anti-resonant circuit converter (U) the rectifier valves of which can be moved into the blocking state by the controlling system (V, E) containing a device (GW) for setting the delay angle of the rectifier valves whenever an individual resonant circuit (L1 , C1 ; L2 , C2 ; Ln , Cn ) is to be connected or the last individual resonant circuit in operation is to be disconnected, but which, however, can only be operated to give a reduced output voltage from the a.c. source if one of the connected individual resonant circuits is to be disconnected, said reduced output voltage corresponding roughly to the reduced power output of the a.c. source expected after the individual resonant circuit is disconnected.
