300KW Induction Heat Treatment Machine , 250A Induction Heating Furnace

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.
