This heater is designed for the induction heating sleeper bolts to forging temperatures. It consists of heater box, inductor, transistor frequency converter and three-phase transformer.
The hopper for the semi-product is accomplished by a gravity-fed angled chute from which the billets are transferred to the feeder sled. The billets are the shifted from the feeder sled to the inductor entrance. System control is handled by a Siemens programmable logic controller. The temperature of each heated piece is measured by a non-contact pyrometer and the date/time 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 display. The heater parameters (desired temperature, power level, temperature ranges, employee login, etc) are all set on the PLC display. This same display also communicates any faults in the induction heating system to the operator.
