Induction Heating Principle
Heating Principle Of Induction
How exactly does induction heating work? It helps to have a basic understanding of the principles of electricity. When an
alternating electrical current is applied to the primary of a transformer, an alternating magnetic field is created. According to Faraday's Law, if the secondary of the transformer is located within the magnetic field, an electric current will be induced.
In a basic induction heating setup shown in, a solid state RF power supply sends an AC current through an inductor (often a copper coil),and the part to be heated (the workpiece) is placed inside the inductor. The inductor serves as the transformer primary and the part to be heated becomes a short circuit secondary. When a metal part is placed within the inductor and enters the magnetic field, circulating eddy currents are induced within the part.

1. What is the Full Automatic Wheels Steel CNC Induction Quenching Machine Tool?
It is an automated CNC induction heating and quenching system designed primarily for hardening steel parts such as wheels. It uses high-frequency induction heating with rapid quenching to change surface hardness and improve wear resistance while offering CNC-controlled process repeatability.
2. How does induction heating in this machine work?
A solid-state RF power supply drives an inductor (a copper coil). The workpiece placed inside the coil acts as the transformer's secondary and eddy currents are induced in the metal. These eddy currents produce rapid, localized heating. The system then applies quenching to harden the heated zone.
3. What are the main electrical and performance specifications?
Model: JLC-120KW. Power: 120 kW. Voltage: 3-phase 380 V, 50/60 Hz. Max input current: 195 A. Oscillating frequency: 10–30 kHz. Duty cycle: 100%. Cable length: 2–6 meters. Cooling water: >0.2 MPa and >6 L/min, temperature ≤40°C.
4. What cooling/water requirements does the machine have?
The system requires a stable cooling water supply with pressure greater than 0.2 MPa, flow over 6 L/min, and water temperature at or below 40°C. Adequate filtration and gradual flow control are recommended to prevent cavitation and protect the power electronics.
5. What materials and parts can be processed?
The machine is optimized for ferrous materials (carbon and alloy steels) that respond to induction hardening and quenching. It can process wheels and similar steel components. Nonferrous metals (aluminum, copper) heat differently and are generally not suitable for quench hardening with this system.
6. What does the 10–30 kHz frequency range mean for processing?
Frequency controls the heating penetration depth: higher frequencies (toward 30 kHz) produce shallower, surface-focused heating for thin case depths; lower frequencies (toward 10 kHz) penetrate deeper. The machine's 10–30 kHz range covers many typical wheel and component case-hardening requirements.
7. Is the machine fully automatic and CNC-controlled?
Yes. It uses CNC control for repeatable positioning and process sequencing. The RF generator employs MOS/IGBT frequency-conversion tracking and supports automatic frequency tracking, constant-current and constant-power control, and integration with temperature feedback for closed-loop operation.
8. Does it have temperature monitoring and automatic control?
The system supports infrared temperature measurement (optional/available) for automatic temperature feedback and closed-loop control, improving heating accuracy and reducing the need for manual adjustments.
9. What built-in protections and safety features are provided?
The unit includes multiple fault protections such as over-current, over-voltage, water-shortage, and phase-missing detection. Because it uses solid-state medium-voltage electronics rather than very-high-voltage equipment, it reduces some electrical hazards, but proper grounding and safety measures are still required.
10. What installation requirements should I prepare for?
Prepare a stable 3-phase 380 V power supply sized for the unit (up to the listed max current), a chilled/circulating water system meeting the flow and pressure specs, adequate ventilation, a leveled and load-bearing floor area, and proper grounding. Exact footprint and anchoring depend on the chosen configuration—confirm with the supplier.
11. What routine maintenance does the machine need?
Regular maintenance includes checking and maintaining cooling water quality and flow, inspecting coils and connectors for wear, cleaning filters and vents, verifying cable and grounding integrity, and periodic inspection/testing of power electronics modules (IGBT/MOS). Follow the manufacturer's maintenance schedule for parts replacement and calibration.
12. What are common fault codes and basic troubleshooting steps?
Typical faults include over-current, over-voltage, water shortage, and phase missing. Basic checks: verify cooling water flow/temperature and pressure, confirm all three-phase power present and within spec, inspect coil and bus connections for shorts/loose contacts, and restart the system per manual. If faults persist, consult authorized service.
13. What is the maximum workpiece size or weight this machine can handle?
Maximum part size and weight depend on the chosen coil, chuck/fixture, and CNC handling configuration rather than the generator alone. Contact the supplier with your specific part dimensions and mass so they can recommend or design the appropriate coil, fixtures, and automation package.
14. Can the machine be integrated into an automated production line?
Yes. The CNC and control architecture, along with automatic frequency tracking and temperature feedback, make the system suitable for integration into automated production lines. PLC/communication interfaces and custom fixturing are typically provided to match line control protocols—discuss integration requirements with the manufacturer.
15. What support, training, and warranty options are available?
Service, commissioning, operator training, and warranty terms vary by supplier and region. Contact the manufacturer or authorized dealer for details on warranty coverage, available training programs, spare parts packages, and onsite commissioning/support options.
