FAQ:


How does frequency affect induction heating?

Operating frequency affects current concentration and heating penetration. Higher frequencies generally concentrate heat closer to the surface and are suitable for localized heating or surface treatment. Lower frequencies provide deeper penetration and are often more suitable for larger or thicker workpieces.

What is the best frequency for induction heating?

There is no single frequency that is suitable for every application. Frequency should be selected according to the workpiece material, diameter, required heating depth, target temperature, production speed and induction coil design. Higher frequency does not automatically mean faster or more efficient heating.

How do I select the right ZG-HF model?

Provide the workpiece material, dimensions, heated area, target temperature, required cycle time, available input voltage and production quantity. Based on this information, the appropriate power supply, frequency range, transformer and coil can be evaluated.

Can a high-frequency induction heater heat steel rods and bars?

Yes, it can be used for localized heating, end heating, surface hardening and preheating of suitable rods and bars. However, large-diameter bars requiring uniform through-heating may need a lower-frequency induction heating system.

Does the ZG-HF Series require water cooling?

The ZG-HF Series is water-cooled. The power supply, transformer and induction coil must operate within the specified water temperature, pressure and flow requirements. The exact cooling requirements should be listed separately for each model.
