Intermediate frequency induction heating system is a widely used heating technology in the industrial field, with a working frequency typically ranging from a few hundred hertz to several thousand hertz, between audio and radio frequency. This heating method utilizes the principle of electromagnetic induction to generate eddy currents in the metal workpiece through an alternating magnetic field, thereby converting electrical energy into thermal energy and achieving rapid heating of the metal. Compared with high-frequency and ultra-high frequency induction heating, medium frequency induction heating systems provide a better balance in penetration depth and heating area, making them suitable for heating larger cross-sectional metal materials.
working principle
The operation of the intermediate frequency induction heating system is based on Faraday's law of electromagnetic induction. When an alternating current passes through an induction coil, an alternating magnetic field is generated near the workpiece. This magnetic field will generate eddy currents inside the workpiece, that is, induced currents. The flow of current generates Joule heat, thereby causing the workpiece to heat up. The frequency selection of the intermediate frequency ensures a moderate depth of thermal penetration, neither shallow nor deep, suitable for heating thick metal materials.
Main components
Induction coil: carries alternating current and generates a magnetic field.
Power supply: Provide stable intermediate frequency current.
Control system: Adjust frequency and power output, monitor heating process.
Cooling system: Ensure that coils and other components do not overheat due to prolonged operation.
Supporting mechanism: Position and fix the workpiece to be heated.
Characteristics and advantages
High heating efficiency: high energy conversion efficiency and low heat loss.
Uniform heating: By adjusting the frequency, more uniform heating can be achieved.
Non contact heating: There is no direct contact with the workpiece, reducing the risk of contamination.
Fast heating speed: Compared to methods such as resistance heating, the heating speed is much faster.
Wide applicability: Suitable for heating various metal materials and large cross-sectional workpieces.
Typical applications
Intermediate frequency induction heating systems are widely used in many industries:
Metal processing: preheating before welding and forging of steel pipes.
Heat treatment: surface quenching, tempering and other heat treatment processes.
Casting: alloy melting and insulation.
Oil and gas: Heating of pipeline welding, valves, and fittings.
Aerospace: Thermal assembly of aircraft components.
Automobile manufacturing: Heating of components such as wheels and bearings.
conclusion
The medium frequency induction heating system plays an important role in modern industrial production due to its high efficiency, speed, and controllability, especially in situations where precise control of heating depth and uniformity is required. With the continuous advancement of technology, intermediate frequency induction heating systems are developing towards automation, intelligence, and modularity to better adapt to increasingly complex industrial needs.
