This heater series is designed for induction heating of cross-sectionally round steel billets up to forging temperatures. The first part of this system is the bin unloader, which handles emptying of the bins into the vibratory drum feeder. The billets leave the drum feeder oriented lengthwise and consecutively to a conveyor with a pneumatic jaw mechanism. These jaws advance the billets toward the inductor opening. The heater is also equipped with a jaw extractor for hot billets leaving the inductor, which removes them and sorts them into one of three categories. Properly heated pieces are placed on the delivery conveyor, and underheated and overheated are sorted to two pallet bins. Heater control is handled by an Siemens programmable logic controller (PLC). The temperature of each heated piece is measured with a non-contact pyrometer and the time/date stamp and temperature value can be saved to the PLC memory. The operator interfaces with the induction heater using the control panel which includes push-buttons and an interactive PLC display. The heater parameters (desired temperature, power level, temperature ranges, employee code, etc) are all set on the PLC display. This same display also communicates any system faults to the operator.
