Compared to traditional thyristor-based medium-frequency equipment, this 90kW furnace employs IGBT inverter technology to reduce energy consumption by over 20% and supports continuous operation at 100% load. It is particularly well-suited for applications such as metal melting, forging, heat treatment, thermal assembly, and scientific research.

Produktfunksjoner

1. IGBT Power Devices for High Efficiency and Energy Savings

Utilizing IGBT power devices and a dual-control converter technology based on parallel resonance, the system allows for independent control of power and frequency conversion. Compared to traditional SCR-based medium-frequency equipment, it offers energy savings of over 20% and maintains an exceptionally high power factor and power supply efficiency across the entire power range. Its compact and lightweight design makes it ideal for use in factories, schools, and research institutions.

2. 100% Duty Cycle for Robust Continuous Operation

The equipment is designed for a 100% duty cycle, supporting continuous full-load operation over extended periods. It utilizes IGBT switching devices and amorphous inductors to form a high-frequency chopping circuit for power regulation.

3. Wide Frequency Range to Meet Diverse Heat Penetration Needs

With a frequency range of 1–20 kHz, the system can be matched to the specific dimensions of the workpiece or the required depth of heat penetration, offering broad application versatility. Medium-frequency heating provides deep penetration, making it suitable for the through-heating of large metal workpieces in processes such as melting, deep heating, and forging.

4. LC Series Resonance for Efficient Energy Transfer

The system operates on the principle of LC series resonance, where the induction coil (L) and capacitor bank (C) form a resonant circuit. In the resonant state, impedance is minimized and current is maximized, enabling efficient energy transfer to the workpiece via eddy current heating.
