COMPLETE EQUIPMENT FOR INDUCTION HEATING
KSO-T-series medium-frequency billet heaters are designed for the inductive heating of steel billets with circular or square cross-section up to forging temperatures. The inductor is accompanied by a transistor-based frequency converter. The advantages of placing the frequency converter in the heater are:
The heater is comprised of three modules: feeding, heating and delivery. At the customers request, the heater can also be equipped with an automatic hot billet sorter.
Heater control is accomplished by a programmable logic controller (PLC). The temperature of every heated billet is monitored by a non-contact temperature sensor. Its temperature value and time stamp can then be stored in the PLC memory. System control is performed via an interactive display panel and push-buttons all located at the main operation panel. Heater specifications (desired temperature, output power level, temperature range, employee code, etc.), are all set on the display. Any system failures are also listed on this display.

Feeding module is designed for the feeding of cold billets to the inductor entrance. With the KSO-T series, the feeding system is comprised of a chain conveyor, which delivers the billets to the area directly in front of a piston which pushes the billet into the inductor. Billets can be placed on the conveyor manually, or a plate feeder can be used. Information about our plate feeders is located in their own catalog list.
Heating module contains:
The inductor is placed on top of the machine. New mid-frequency input connectors and cooling system quick-couplers allow for minimal down-time when the inductor needs to be changed out. We can design inductors with a square or circular heating chamber. Inductor dimensions can be interpreted by noting the model series, the following sizes are available: 20, 25, 30, 35, 40, 45, 50. Of course, inductors of other dimensions can be designed, built, and delivered exactly to our customer's specifications.
The delivery module is designed for removal of the billet from the inductor core.
At the customer's request, the gravity chute can be coupled with:
