Core of uniform heating for steel plate induction hardening furnace

The core of uniform heating for steel plate induction hardening production line lies in the synergistic effect of IGBT induction heating power supply and electromagnetic induction principle, which directly heats the surface of the steel plate through high-frequency current, achieving high efficiency, energy saving and temperature uniformity. The specific principle of the steel plate induction hardening furnace is as follows:

1. Electromagnetic induction heating mechanism

Eddy current generation: IGBT power supplies output high-frequency alternating current (200-300kHz), which generates an alternating magnetic field through an induction coil and generates eddy current (induced current) inside the steel plate.

Skin effect: High frequency current concentrates eddy currents on the surface of the steel plate, forming "surface heating" and reducing the temperature of the core to avoid overheating and deformation.

Joule heating effect: Eddy currents generate heat through steel plate resistors, achieving rapid heating (up to 800-1000 ℃ within seconds).

2. Energy saving and uniformity guarantee

Advantages of IGBT power supply: Compared with traditional resistance furnaces, IGBT power supply has a thermal efficiency of over 60% and energy savings of over 30%.

Temperature control: The PLC intelligent system monitors the temperature of the steel plate in real time, adjusts the current frequency and power through feedback, and ensures uniform surface temperature.

Medium free heating: directly using the resistance of the steel plate to generate heat, avoiding the loss of heat transfer medium in traditional heating.

3. Application scenario adaptation

Thin steel/medium thick steel: By adjusting the frequency and power, it can meet the quenching requirements of steel plates of different thicknesses.

Automated production: The roller conveyor+power double pinch roller system realizes continuous feeding, and cooperates with the industrial computer system to record parameters, ensuring consistency in batch production.

Forever Electromechanical has achieved efficient, energy-saving, and uniform heating of steel plate induction hardening mahcine through the above technology, which is suitable for the high-strength needs of industries such as mining machinery and railway transportation.
