1. Energy Transformation:

2. This equipment transforms conventional 50Hz industrial alternating current into high-frequency AC,laying the fundamental energy source needed to produce magnetic fields in the follow-up process.

3. Magnetic Field Formation:

4. As high-frequency electric current flows through the induction coil,an alternating magnetic field comes into being, with its field strength fluctuating swiftly in line with the frequency of the applied current.

5. Eddy Current Thermal Effect:

6. Positioning an electrically conductive workpiece adjacent to the induction coil triggers fluctuating magnetic flux,which induces eddy currents inside the component.Restricted by the workpiece’s inherent resistance,such eddy currents produce heat and bring about fast temperature elevation.

3. Welding Fabrication

4. Applicable to welding operations of copper, aluminium, silver and assorted metallic materials; it delivers consistent heating on weld zones and optimizes finished welding quality.

5. Forging & Moulding

6. The equipment enables localized heating on rod and sheet metal ends, supplying steady thermal energy to support forging, bending and similar forming procedures.

7. Pipeline Construction & Thermal Fitting

8. It serves preheating of industrial pipelines, post-weld thermal treatment for weld joints, as well as hot fitting and dismantling of motor bearings and various mechanical spare parts.

9. IV.Product Features Introduction:

• Industry-leading wide inductance design

• Designed with widely adjustable inductance ranging from 2μH to 600μH, the electromagnetic induction heating system spans low-inductance configurations for precise localized heating up to high-inductance setups suited for deep penetration heating of bulky workpieces, making it adaptable to various industrial application conditions. Equipped with self-adaptive resonance regulation technology, the unit achieves high-efficiency energy coupling amid varying loads including shifts in metallic workpiece composition and dimension, which greatly boosts the equipment’s universal adaptability and thermal efficiency.

• Integrated isolation transformer

  Nanocrystalline magnetic cores help cut down high-frequency eddy current loss and elevate overall operational efficiency. An isolating transformer can efficiently suppress noise stemming from high-frequency inverters and mitigate electromagnetic interference against the utility grid; furthermore, it electrically separates the output terminal from the mains supply to advance the safety of output circuits.

• Precise temperature control improves process quality.

  --It delivers precise temperature regulation with a tolerance of ±3℃ and can reach an optimal accuracy of up to ±1℃, which fits demanding working conditions including semiconductor processing and precision metal thermal treatment.

• --Non-contact thermal processing prevents workpiece oxidation and dimensional distortion,thereby securing consistent physical properties of processed materials.

• High stability and comprehensive fault mechanisms The equipment supports round-the-clock continuous full-load operation. For the three-phase 400VAC variant,normal running is maintained amid grid voltage swings within ±20%.In addition,the unit is equipped with comprehensive protective functions covering overvoltage,overcurrent,open-phase and over-temperature conditions.

• Safe and reliable, industrial-grade protection design

  This intermediate-frequency induction heating power source is constructed with either standalone air-cooling or full water-cooling configurations.Its printed circuit boards and related electronic parts undergo three-pass conformal coating treatment,enabling reliable deployment in sophisticated operating surroundings including offshore platform sites.

• Data storage

  Real-time display and system storage are available for the heating temperature curve.Operators may retrieve heating records whenever needed,and upon completion of heating processes,all historical thermal data can be exported to a USB storage device for backup.

• Multi-segment process curve

  The system is equipped with diverse control options consisting of constant power mode,power-time curve mode, constant-temperature mode (with the relevant constant-temperature control module supplied as an optional accessory),as well as temperature-time curve mode. Operators are allowed to switch among these options in accordance with varying working circumstances and technical demands.

• Remote control (customized module)

  Built-in WiFi,5G wireless,RS485 as well as TCP/IP MODBUS communication modules are integrated into the equipment to realize remote monitoring and operational control.

• Diverse power control modes

• Output power can be controlled via 0-10V,0-5V,4-20mA,and digital adjustment.
