Advanced Induction Thermal Processing for Precision Manufacturing: Multi-Physics Synergy and High-Frequency Resonant Control

The rapid global transition toward green industrial manufacturing and carbon neutrality has placed stringent requirements on the thermal processing of critical components, such as industrial pipes and shaft parts. Traditional heat treatment technologies, including gas combustion and resistance heating, suffer from severe energy losses, slow dynamic response, and limited precision in digital control. This monograph presents a comprehensive investigation into high-frequency resonant induction heating systems, establishing an integrated framework spanning physical mechanism innovation, multi-physics field coupling, topology modeling, and digital hardware implementation.Key Contributions & Value Proposition[1]. Synergistic Control Topology: Combines magnetic field cancellation/superposition with Buck chopper power tuning for wide-range, high-precision thermal control.[2].
