KSO 250/4-A38L Compact Mid-frequency Heater, Power Class 250 kW

This heater is designed for the induction heating of cross-sectionally round steel billets to forging temperatures. It is designed for manual placement of the billets including the ability to place more billets at one time into the angled feed chute. The system is controlled by a Unitronics 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.   Billets can leave the inductor one of two ways:

1. Gravitationally - this is rather designed for shorter billets.  The billets fall into a fixed chute.
2. Roller extractor - must be manually set in place for longer billets just after the inductor exit.  This helps guide the billets leaving the inductor in such a manner that that billet exit angle doesn't change until the entire billet is clear of the inductor core.

For both exit systems, it is possible to use a billet separator which functions to separate billets which are occasionally stuck to each other.  Furthermore, the heater is equipped with a hot billet sorter, which blocks improperly-heated billets (either underheated or overheated) from being delivered to the press.  Heater controls are handled by a Unitronics programmable logic controller (PLC).  The temperature of each billet 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.
