The auxiliary facilities for medium- and high-frequency induction heating furnaces can be categorized into core infrastructure and process-support systems. The power supply unit converts mains-frequency AC into medium-frequency power (ranging from 300 Hz to 20 kHz); through rectification and inversion, it generates an adjustable current that utilizes the principle of electromagnetic induction to induce eddy currents within the metal material itself, thereby achieving heating.
Medium/High-Frequency Power Supply
Serving as the core energy conversion unit, this component converts mains-frequency AC power into the appropriate medium- or high-frequency current. Modern systems predominantly utilize energy-efficient IGBT power supplies, which can be customized based on heating power and frequency requirements to suit various through-heating, hardening, and melting processes.
Furnace Body and Induction Coil
The furnace assembly comprises the induction coil, furnace lid, crucible, support structure, and other elements. Small-scale systems often feature a dual-furnace setup (one active, one standby) to ensure continuous production. The induction coil-wound from high-purity oxygen-free copper tubing-is the core component that directly heats the workpiece; its design is customized to match the workpiece's shape.
Mechanical Transmission and Handling Systems
This category includes hydraulic or electric drive mechanisms for moving the furnace lid and tilting/resetting the furnace body, as well as components for loading and feeding materials-such as electromagnetic chucks, charging carts, pneumatic pushers, and sprocket-driven feed mechanisms-to meet diverse automated production requirements.
Temperature Measurement and Discharge Mechanism
Optional thermocouple or infrared temperature sensing units enable precise control of workpiece heating temperatures; the discharge end can be configured with a three-way sorting and rapid extraction mechanism to facilitate the classified transfer of workpieces across different temperature ranges.
Central Control Console
Integrates all equipment control units to enable unified, visual management of heating parameters and operational status, significantly enhancing the system's automation level.
Specialized Process Machine Tool
Designed for quenching applications involving components such as shafts and gears, the system can be paired with a CNC quenching machine tool to ensure precision in heating travel and positioning, thereby preventing issues such as soft spots or deformation.
