ABSTRACT:
An induction heating system for heating an end length of a forging bar following the cut-off therefrom of a previously heated and forged end length is arranged to bring the end length to be heated to a uniform temperature despite the existence of a residual hot end portion from the previous heat. The heating system has an induction heating coil with a longitudinally extending axial passageway therethrough for receiving the bar length to be heated by insertion into a feed-in end of the coil passageway. A stop member is positioned adjacent the open other end of the passageway to abut the forward end of the inserted bar so as to locate it wholly within the passageway. Electrical circuitry is arranged to connect an AC power supply first to a partial portion of the length of the heating coil extending from the feed-in end thereof so as to heat the as yet unheated portion of the inserted bar end length to a temperature more or less corresponding to that of the residually heated endmost portion of the inserted bar length. Thereupon, the electrical circuitry then connects the full length of the heating coil to the power supply so as to evenly heat the inserted bar length throughout its entire extent to the desired forging temperature.
