Medium-Frequency Induction Heating Power Supply

Medium-Frequency Induction Heating Power Supply

The medium-frequency induction heating power supply is industrial equipment designed based on the principle of electromagnetic induction for rapid, efficient heating. It offers customizable output power ranging from 15 kW to 160 kW and an output voltage of 70–200 V. The system utilizes advanced IGBT/MOSFET series resonant inverter technology to convert standard line-frequency power into medium-frequency current (1–20 kHz). inducing eddy currents within the metal workpiece and causing rapid heating. Compared to high-frequency induction heating, medium-frequency heating offers greater current penetration depth and superior heat penetration capabilities.

Produktfunksjoner

1. Customizable Power Output (15–160 kW)

The equipment offers customizable output power ranging from 15 kW to 160 kW and an output voltage of 70–200 V, meeting heating requirements for metal workpieces of various sizes and materials.

2. Deep Penetration for Large Workpieces

With a frequency range of 1–10 kHz, the current penetration depth reaches 1–10 mm. This offers greater penetration depth compared to high-frequency heating, making it ideal for processing large-volume or thick-walled metal workpieces.

3. Vacuum Heating with Glow Discharge Prevention

This equipment is specifically designed for heating applications in vacuum environments. Through optimized design and insulation measures (such as high-temperature tape, ceramic paste, varnish, or shielded housings), it effectively prevents coil glow discharge in a vacuum.

4. High-Efficiency, Stable IGBT Series-Resonant Inverter

Utilizing a series-resonant inverter topology based on IGBT/MOSFET technology, the system converts mains frequency power (50/60 Hz) into medium-frequency power (1–20 kHz). Operating at the resonant point maximizes energy transfer efficiency while minimizing losses.

5. High Application Flexibility

Suitable for a wide range of industrial processes, including melting, shrink fitting, sintring, forging, spraying, annealing, and surface hardening. Custom induction coils can be designed for specific workpiece shapes, ensuring flexible adaptation to diverse production needs.

Ofte stilte spørsmål (FAQ)

1. What is the difference between medium-frequency and high-frequency heating?

Medium-frequency heating operates at a lower frequency and offers greater current penetration depth, making it suitable for large workpieces and through-heating; high-frequency heating is better suited for rapid surface heating and shallow heat treatment.

2. Can the equipment power output be customized?

Ja.

3. Can the induction coil be customized?

Ja. The coil shape, dimensions, number of turns, and cooling method can all be professionally designed to meet specific workpiece requirements.

4. Does the equipment require a cooling system?

Ja. The medium-frequency power supply, capacitors, and induction coil all require a circulating water cooling system to ensure stable operation and extend the equipment’s service life.

5. What safety protection features does the equipment have?

Standard features include over-current protection, over-voltage protection, water-shortage protection, over-temperature protection, and fault alarm functions, ensuring safe and reliable equipment operation.
