Crafted by manufacturers like Taizhou Hongkang Electric Co., Ltd., these furnaces harness advanced technology to optimize metal melting processes, presenting a host of advantages over conventional methodologies.

Principle of Operation

At the heart of the Metal Melting Induction Furnace lies the principle of series resonance. Within the furnace circuit, the combination of inductive reactance from the furnace coil and capacitive reactance from the circuit forms a resonant circuit. This resonance is crucial for efficient energy transfer, enabling rapid and uniform heating of the metal charge. Facilitating this precise energy delivery are thyristor-based power electronics, which regulate the power flow to the furnace, ensuring optimal performance and temperature control.

  1. Inductive Reactance: Inductive reactance, generated by the furnace coil, creates a magnetic field that induces currents in the metal charge, heating it rapidly and uniformly.
  2. Capacitive Reactance: Capacitive reactance, contributed by the circuit’s capacitors, complements the inductive reactance to establish series resonance, maximizing energy transfer efficiency.
