Mid-frequency induction heater made for Federal-Mogul Valvetrain s.r.o., Dačice, is used for induction heating of rods with circular cross-section up to required temperature for mechanical cutting of steel rods. It consists of heater box, inductor, frequency converter and three-phase transformer.
The heater is controlled by Programmable Logic Controller (PLC) made in Siemens. The temperature of each heated rod is measured by a non-contact temperature gauge and its value and time of measurement can be stored in the PLC memory. The induction heater is operated from the control box with buttons and the communication panel. Heating parameters (required temperature, output, temperature limits, operator´s code) are set on the communication panel. All failures of the heater are displayed in text on this panel, including the instructions for troubleshooting.
