Medium Frequency Furnace High And Medium Frequency Induction
Heating Furnace With Low Failure Rate
Working principle of intermediate frequency furnace:
The medium frequency furnace is a power supply device that converts
the power frequency 50Hz AC to the medium frequency (above 300Hz to
1000Hz). It converts the three-phase power frequency AC into DC
after rectification, and then converts the DC into an adjustable
medium frequency current. It supplies the medium frequency
alternating current flowing through the capacitor and the induction
coil, generates high-density magnetic lines in the induction coil,
and cuts the metal materials contained in the induction coil,
generating large eddy currents in the metal materials.

Features of intermediate frequency furnace:
1. It can be controlled manually or automatically by using the
automatic control panel. According to customer requirements,
infrared controller can be additionally configured to make heating
more intelligent.
2. The machine uses the principle of electromagnetic induction,
which can penetrate non-metallic materials and instantly induce
heat to any metal in a non-contact manner;
3. IGBT inverter power device is adopted, which is efficient and
energy-saving and easy to control heating. The heating current
value and the heating voltage value can be set, and the current,
voltage, power and frequency are all displayed. The operation is
intuitive, simple and convenient.
4. The traditional intermediate frequency parallel resonance
structure is adopted, with a large frequency range, from 1kHz to
20kHz. It can be matched according to the size of the specific
heating workpiece or the depth of heat penetration, and has a wide
range of adaptability. Simple load matching, high equipment
efficiency and high utilization.
5. The machine has multiple self-protection functions: overvoltage,
overcurrent, water shortage, overheating, high frequency, low
frequency, phase loss protection, etc. in case of any manual error
during operation, the machine will automatically alarm immediately
to protect its own life.
