ABSTRACT:
Elongated workpieces having an extended intermediate portion of substantially uniform cross-section and axially spaced end or other portions of enlarged cross-section are inductively heated to a desired surface temperature by axially moving them at a continuous rate of speed coaxially of and sequentially through a succession of three axially aligned multiturn induction heating coils and energizing selective ones of the heating coils, during the passage therethrough of selected ones of the workpiece portions to inductively heat the same to the desired surface temperature. The coils have separate power supply circuits for energizing the coils, and suitable control means are provided for activating the power supply circuits to energize the coils in succession and during the travel of the selected portions of the workpiece through selected ones of the heating coils.
