200KW High Frequency Induction Hardening Equipment

How exactly does induction hardening equipment work?

Through the conversion of the high-frequency gear induction hardening equipment, the 50HZ/60HZ alternating current is converted into a direct current voltage, and then the direct current is converted into a 20-40KHZ high-frequency voltage output through the control circuit. The fast-moving high-voltage current will produce high-speed changes in the cable. After the magnetic field cable is in contact with the iron container, the surface of the container will cut off the AC magnetic lines of force and generate alternating current on the metal part at the bottom of the container. The vortex causes the iron atoms at the bottom of the container to move irregularly at high speed.

Induction heating is to generate current eddy currents in the inductor coil through alternating current so that the electron holes in the magnetically conductive objects in the coil move to generate heat. High-frequency CNC induction hardening equipment can instantly heat metal objects to any desired temperature, including their melting point.

The high-frequency crankshaft induction hardening equipment is composed of a bed, loading and unloading mechanism, clamping and rotating mechanism, quenching transformer and resonance tank circuit, cooling system, quenching liquid circulation system, electrical control system, etc. Two main types: vertical and horizontal. The induction hardening process is mainly realized by the cooperation of the hardening machine tool and the medium and high-frequency power supply. It is used for various gears, bearings, shaft parts, valves, cylinder liners, and various machinery. The parts are quenched and heat treated.

A 200kW high frequency induction hardening system consists of several key components that work together to deliver efficient, precise, and reliable heat treatment:

Power Supply
Converts standard AC power into high-frequency current, providing stable 200kW output for efficient heating.

Induction Coil
Generates a high-frequency magnetic field to heat the workpiece. Typically water-cooled and customized for different part shapes.

Transformer & Resonant Circuit
Ensures efficient energy transfer between the power supply and the coil, improving heating performance and stability.

Mechanical Handling System
Positions and moves the workpiece during processing, including rotation, scanning, and clamping for consistent results.

Quenching System
Rapidly cools the heated area using spray or immersion methods to achieve the required hardness.

Cooling System
Uses water cooling to protect the coil, power components, and cables from overheating.

Control System (PLC/CNC)
Provides precise control of power, frequency, and heating time through a user-friendly interface.

Safety Protection System
Includes safeguards such as overcurrent, overvoltage, and water flow protection to ensure safe operation.

Among the metals, those with high melting point are relatively large in power, and those with low melting point are relatively small; those with low resistivity are more powerful, and those with high resistivity are less power.

The shape of the welded parts of the high-frequency heating machine is almost unlimited, the outline pattern will not be damaged, the external crystal layout of the metal remains unchanged, the annealing range is small, and it is widely used in the metal glasses manufacturing industry without welding scars. High-frequency quenching uses high-frequency current to locally heat and cools the surface of the workpiece to obtain a surface-hardened layer.
